Description

Technical field

[0001] The present invention relates to a correction of a production plan. State of the art

[0002] In Japan, China, Europe, America, and elsewhere, the automation of production facilities is being promoted to make production more efficient. On the other hand, legal regulations regarding the emission of pollutants such as carbon dioxide have become more stringent in recent years.

[0003] To comply with legal requirements, the introduction of a renewable energy supply system is currently being considered as an energy supply system that supplies the production facility with electrical energy. Examples of renewable energy supply systems include photovoltaic energy generation (hereinafter also referred to as PV (photovoltaic) energy generation) and an EV equipped with V2X (Vehicle-to-Everything).

[0004] In these situations, it is expected that the proportion of energy supplied by the renewable energy supply facility to the demanded amount of electrical energy, which is the energy consumption amount or the energy consumption amount of the production facilities and supply facilities, will increase. Supply facilities are facilities or facilities that provide the production facilities with the resources required for production.

[0005] In this way, since the proportion of energy supplied by the renewable energy supply facility to the amount of energy demand is expected to increase, a balance is required between the operation of the production and supply facilities and the operation of the renewable energy supply facility. By achieving a balance in operation, it is possible to reduce carbon dioxide emissions while maintaining production efficiency, thus making it possible to comply with legal regulations.

[0006] Patent Literature 1 discloses a method for optimizing an electric energy price by adjusting a production plan.

[0007] More specifically, in the technology of Patent Literature 1, based on a predetermined price plan, production is carried out in a night time zone with a low unit price of electric energy, thereby optimizing the price of electric energy. Reference listPatent literature

[0014] Embodiments are explained below using the drawings. In the following description of the embodiments and in the drawings, components with the same reference numerals denote the same part or correspond to each other. Embodiment 1.***Description of the system structure***

[0015] Fig. 1 shows an example of a production plan optimization system 100 according to Embodiment 1.

[0016] As in Fig. 1, the production plan optimization system 100 comprises production facilities 1, a production control device 2, a supply facility 3, a production plan generation device 4, renewable energy supply facilities 5, a supply control device 6, a supply facility operation plan generation device 7, an optimization device 8, a display device 9, and a network 10.

[0017] In the present embodiment, an example is described in which the production plan optimization system 100 includes three production facilities 1. However, the number of production facilities 1 is arbitrary.

[0018] In the present embodiment, an example will be further described in which the production plan optimization system 100 includes one supply facility 3. However, the number of supply facilities 3 is arbitrary.

[0019] In the present embodiment, an example is further described in which the production plan optimization system 100 includes three renewable energy supply plants 5. However, the number of renewable energy supply plants 5 is arbitrary.

[0020] Note that the production plan generation device 4, the supply facility operation plan generation device 7, and the optimization device 8 correspond to an information processing system 500. Furthermore, the operation to be performed in the production plan generation device 4, the supply facility operation plan generation device 7, and the optimization device 8 corresponds to an information processing method. Furthermore, a program that realizes the operation of the production plan generation device 4, the supply facility operation plan generation device 7, and the optimization device 8 corresponds to an information processing program.

[0021] The production facilities 1 are used to manufacture articles. The production facilities 1 produce articles by receiving electrical energy provided by the renewable energy supply facilities 5.

[0022] The production equipment 1 includes, for example, an injection molding machine or an extrusion molding machine, which processes the raw materials of the articles. The production equipment 1 may also include machining equipment such as a lathe and a grinder. Furthermore, the production equipment 1 may include assembly equipment, which assembles the articles by fastening them with components such as screws and nuts. The production equipment 1 may also include testing equipment such as magnetic particle inspection equipment, radiographic inspection equipment, and penetrant inspection equipment.

[0023] The production control device 2 controls the production facilities 1 by following an article production plan and administers the production of articles.

[0024] The production control device 2 is, for example, a programmable logic controller (PLC) or the like.

[0025] The supply system 3 provides the production systems 1 with a resource necessary for production.

[0026] The resource to be provided by the supply system 3 for the production systems 1 is, for example, cold water, hot water, compressed air, electrical energy or the like.

[0027] Although not illustrated, the production facilities 1 and the utility facility 3 are connected via a supply channel for supplying a resource, such as a water supply pipe, an air supply pipe, a cable line, or the like. Note that the utility facility 3 is a facility that cannot be controlled by the production control device 2. Furthermore, an administrator for administering the production facilities 1 may be different from an administrator for administering the utility facility 3. Furthermore, the utility facility 3 provides the resource only to the production facility 1 controlled by the production control device 2. The utility facility 3 does not provide the resource to the production facility 1 not controlled by the production control device 2.

[0028] The production plan generation device 4 generates a production plan for the production facilities 1.

[0029] Furthermore, when an instruction to correct the production plan is issued from the optimization device 8, the production plan generation device 4 generates a production plan correction suggestion. Then, the production plan generation device 4 generates a new production plan based on the production plan correction suggestion.

[0030] The renewable energy supply systems 5 each comprise a renewable energy generation facility. The renewable energy supply system 5 supplies the production systems 1 with electrical energy generated by the renewable energy generation facility.

[0031] The renewable energy supply systems 5 are power generation systems whose energy generation amount fluctuates depending on the change in the external environment. "The change in the external environment" refers to the fact that the state of the environment in which energy is supplied to the power generation systems as a source for conversion into electrical energy changes over time. In the present embodiment, it is assumed that the renewable energy supply systems 5 each include a photovoltaic (PV) power generation device as a renewable energy generation device.In the present embodiment, in an environment irradiated with optical energy (sunlight) as a source for conversion into electrical energy, the amount of optical energy (sunlight) radiation changes over time, which corresponds to the "change of the external environment state." That is, in the present embodiment, a change in the amount of solar radiation with the passage of time corresponds to the "change of the external environment state." As is known, in the photovoltaic power generation device, a change in the amount of solar radiation changes the power generation amount.

[0032] Furthermore, each renewable energy supply facility 5 may include another renewable energy generation facility, such as a geothermal energy generation facility or a biomass energy generation facility, instead of a photovoltaic energy generation facility. If the renewable energy supply facility 5 further includes another renewable energy generation facility, such as a geothermal energy generation facility or a biomass energy generation facility, the renewable energy supply facility 5 corresponds to a power generation facility in which the energy generation amount fluctuates depending on a change in the state of an external environment.

[0033] Renewable Energy Supply Facility 5 also includes an electric shuttle vehicle (EV) for employee shuttle traffic and an accumulator facility.

[0034] In addition, since, as explained above, the energy generation amount of the renewable energy supply facility 5 fluctuates, the energy generation amount may be insufficient with respect to the amount of electric energy required by the production facilities 1 and the supply facility 3. In the present embodiment, in order to accommodate the insufficiency of the energy generation amount, in addition to the renewable energy supply facilities 5, a Fig. 1 additional energy supply system not shown is present.

[0035] When the energy generation amount is insufficient, the renewable energy supply facility 5 acquires a shortfall of the amount of electrical energy (purchases energy) from the supplementary energy supply facility.

[0036] Based on the production plan generated in the production plan generation device 4, the supply facility operation plan generation device 7 generates a supply facility operation plan, which is an operation plan for the renewable energy supply facilities 5. The supply facility operation plan is an energy supply plan for the renewable energy supply facilities 5.

[0037] In addition, when an instruction to correct the production plan is issued from the optimization device 8, the provisioning facility operation plan generation device 7 generates a proposal to correct the provisioning facility operation plan based on the proposal to correct the production plan by the production plan generation device 4.

[0038] The supply control device 6 controls the renewable energy supply plant 5 by following the supply plant operation plan.

[0039] The supply control device 6 is, for example, a PLC or the like.

[0040] The optimization device 8 determines whether a correction of the production plan generated in the production plan generation device 4 is necessary.

[0041] If it is determined that a correction of the production plan is not necessary, the optimization device 8 approves the production plan. Then, based on the production plan approved by the optimization device 8, the production facilities 1 are controlled. Furthermore, the renewable energy supply facilities 5 are controlled using the supply facility operation plan approved by the optimization device 8.

[0042] On the other hand, if it is determined that a correction of the production plan is necessary, the optimization device 8 issues an instruction to generate a production plan correction suggestion to the production plan generation device 4. Following the instruction from the optimization device 8, the production plan generation device 4 generates a plurality of production plan correction suggestions.

[0043] The optimization device 8 selects any one proposal for correction from the plurality of proposals for correcting the production plan.

[0044] Then, the production plant 1 is controlled with the production plan that follows the correction suggestion selected by the optimization device 8. Furthermore, the renewable energy supply plants 5 are controlled with the supply plant operation plan based on the correction suggestion selected by the optimization device 8.

[0045] The display device 9 generates a display screen that takes into account the production plan approved by the optimization device 8 and displays the generated display screen. The display device 9 includes a monitor, such as a liquid crystal display or an organic EL (electroluminescence) display. The display device 9 displays the generated screen on the monitor.

[0046] Note that in the present embodiment, an example is described in which the display device 9 and the optimization device 8 are separated, but the display device 9 may be integrated with the optimization device 8. That is, the optimization device 8 may have a display function.

[0047] The network 10 connects the components of the production plan optimization system 100.

[0048] Specifically, the network 10 connects the production facilities 1 and the production control device 2. In addition, the network 10 connects the production control device 2 and the production plan generation device 4. Furthermore, the network 10 connects the supply facility 3 and the production plan generation device 4. In addition, the network 10 connects the production plan generation device 4 and the optimization device 8. Furthermore, the network 10 connects the optimization device 8 and the supply facility operation plan generation device 7. In addition, the network 10 connects the optimization device 8 and the display device 9. Furthermore, the network 10 connects the supply facility operation plan generation device 7 and the supply control device 6.Furthermore, the network 10 connects the supply control device 6 and the renewable energy supply systems 5 with each other.

[0049] The network 10 is, for example, a field network such as a CC-Link (Control & Communication Link, registered trademark) network. The network 10 may also be, for example, a general network such as Ethernet (registered trademark) or a dedicated input / output line.

[0050] Note that in the present embodiment, an example is described in which all components included in the production plan optimization system 100 are connected via the same network 10. However, each component may be connected via a different network. *** General principles ***

[0051] Before describing details of the Fig. 1, the production plan generation device 4, the supply plant operation plan generation device 7 and the optimization device 8, general operating principles of the production plan generation device 4, the supply plant operation plan generation device 7 and the optimization device 8 are described here with reference to Fig. 44 and Fig. 45 described.

[0052] First, the production plan generation device 4 generates a production plan (step S411). The production plan defines the general principles of production in Production Plant 1.

[0053] Information that specifies the production plan is called production plan information. Fig. 13 shows an example of production plan information. Details of Fig. 13 are described in more detail below.

[0054] Next, based on the production plan, the production plan generation means 4 generates a production facility operation plan for each unit time (step S412).

[0055] The time unit is a time for the administration of production in the production facilities 1. The time unit is also called a calculation time unit. The time unit is, as in Fig. 15, for example 3,600 seconds (= 1 hour).

[0056] The production facility operation plan is an operation plan for Production Facilities 1 and a plan that details the production plan. In the production facility operation plan, an item (model) is defined for each time unit as a production target, a production quantity, an operation in Production Facilities 1, and so on.

[0057] Information specifying the production facility operation plan is called production facility operation plan information. Fig. 21 shows an example of production plant operation plan information. Details of Fig. 21 are described in more detail below.

[0058] In addition, based on the production facility operation plan, the production plan generation device 4 generates a utility facility operation plan for each unit time (step S413).

[0059] The utility facility operating plan is an operating plan for utility facility 3. In the utility facility operating plan, a provision quantity of a resource provided by utility facility 3, an operation to be carried out in utility facility 3, and so on are defined for each time unit.

[0060] Information specifying the utility operation plan is referred to as utility operation plan information. Fig. Figure 24 shows an example of utility operation plan information. Details of Fig. 24 are described in more detail below.

[0061] Furthermore, based on the production facility operation plan and the supply facility operation plan, the production plan generation device 4 generates a total amount of consumption resources to be consumed in the production facilities 1 and the supply facility 3 (step S414).

[0062] Further, based on the production facility operation plan and the supply facility operation plan, the production plan generation device 4 generates a total amount of environmental pollution emission in the production facilities 1 and the supply facility 3 (step S415).

[0063] Information indicating the total amount of consumption resources calculated by the production plan generation device 4 is referred to as consumption resource information. Furthermore, information indicating the total amount of environmental pollution emission calculated by the production plan generation device 4 is referred to as environmental pollution information.

[0064] Fig. Figure 25 shows an example of consumption resource information and environmental impact information. Details of Fig. 25 are described in more detail below.

[0065] Then, the production plan generation device 4 transmits the production facility operation plan information, the supply facility operation plan information, the consumption resource information, and the environmental load information to the optimization device 8 (step S416).

[0066] Then, the optimization device 8 receives the production facility operation plan information, the supply facility operation plan information, the consumption resource information, and the environmental load information from the production plan generation device 4 (step S811).

[0067] Then, the optimization device 8 transmits the production facility operation plan information, the supply facility operation plan information, and the consumption resource information to the supply facility operation plan generation device 7 (step S812).

[0068] The supply facility operation plan generation device 7 receives the production facility operation plan information, the supply facility operation plan information and the consumption resource information from the optimization device 8 (step S711).

[0069] Next, the deployment facility operation plan generation device 7 generates a PV power generation plan based on weather forecast information (step S712). The PV power generation plan is a power generation plan of the photovoltaic (PV) power generation device included in each renewable energy deployment facility 5.

[0070] Information indicating the PV power generation plan generated by the provisioning facility operation plan generation device 7 is referred to as PV power generation plan information. Fig. 31 shows an example of PV energy generation plan information. Details of Fig. 31 are described in more detail below.

[0071] Further, based on the production facility operation plan information and the supply facility operation plan information, the supply facility operation plan generation unit 7 generates an EV operation plan (step S713). The EV operation plan is an operation plan for the EV. The EV is used for shuttle traffic of employees employed in the production facilities 1 and the supply facility 3.

[0072] Information specifying the EV operation plan is referred to as EV operation plan information. Fig. Figure 32 shows an example of EV operating plan information. Details of Fig. 32 are described in more detail below.

[0073] Further, based on the consumption resource information, the PV power generation plan, and the EV operation plan, the provisioning facility operation plan generation means 7 generates an energy accumulation plan, an electric discharge plan, and a reference plan (step S714).

[0074] The energy accumulation plan is a plan for energy accumulation of a surplus amount of electric energy for a storage battery and / or an EV when the PV energy generation amount exceeds a requested amount of electric energy (amount of electric energy required in the production facilities 1 and the supply facility 3).

[0075] The electrical discharge plan is a plan for electrical discharge of the accumulated surplus amount of electrical energy to the production facilities 1.

[0076] The purchase plan is a plan for purchasing a shortfall in the amount of electrical energy (energy purchase) from the auxiliary energy supply system when the total amount of electrical energy from the PV energy generation amount and the accumulated amount of electrical energy is insufficient for the requested amount of electrical energy.

[0077] Furthermore, based on the consumption resource information, the PV power generation plan, the energy accumulation plan, the electric discharge plan, and the supply plan, the supply facility operation plan generation means 7 generates a supply facility operation plan (step 715).

[0078] Information specifying the deployment facility operating plan is referred to as deployment facility operating plan information. Fig. Figure 35 shows an example of deployment facility operating plan information.

[0079] In the provisioning facility operation plan information, the demand-side energy consumption amount is based on the consumption resource information ( Fig. 25). Furthermore, the PV energy generation amount is based on the PV energy generation plan. The accumulator battery charging / discharging amount and the EV charging / discharging amount are based on the energy accumulation plan and the electrical discharge plan. The energy purchase demand coverage / demand amount is based on the purchase plan. Details of Fig. 35 are described in more detail below.

[0080] Next, the provisioning facility operation plan generation means 7 transmits the provisioning facility operation plan information to the optimization means 8 (step S716).

[0081] The optimization means 8 receives the provisioning facility operation plan information from the provisioning facility operation plan generation means 7 (step S811).

[0082] Then, the optimization device 8 calculates the production cost based on the production facility operation plan information, the supply facility operation plan information, the consumption resource information, the environmental load information, and the supply facility operation plan information (step S813).

[0083] Production costs are the costs required for production that follows the production plan. Production costs include labor costs (personnel costs), environmental pollution costs, and energy purchasing costs (energy procurement costs), which are the costs required to acquire the amount of electrical energy from the auxiliary energy supply system, and so on.

[0084] Next, the optimizer 8 calculates a production evaluation index, which is an index value of the production cost (step S814).

[0085] The optimization device 8 next determines whether a correction of the production plan is necessary (step S815).

[0086] Specifically, the optimization device 8 determines whether the production evaluation index agrees with a target value.

[0087] If the production evaluation index matches the target value, the optimization device 8 determines that correction of the production plan is not necessary. If it is determined that correction of the production facility operation plan is not necessary, the optimization device 8 approves the production plan generated by the production plan generation device 4 (step S816). If the optimization device 8 approves the production plan, the production facilities 1 are controlled with the production facility operation plan generated by the production plan generation device 4. The renewable energy supply facility 5 is also controlled with the supply facility operation plan generated by the supply facility operation plan generation device 7.

[0088] On the other hand, if the production evaluation index does not agree with the target value, the optimizer 8 determines that a correction of the production plan is necessary.

[0089] If it is determined that a correction to the production plan is necessary, the optimization device 8 transmits a correction suggestion generation instruction (step S817). The correction suggestion generation instruction is a command for generating an instruction for generating a suggestion for a correction to the production plan to the production plan generation device 4.

[0090] The optimization device 8 causes the production plan generation device 4 to generate a proposal for the correction of the production plan according to a round-robin scheme or round-robin method in order to satisfy the correction proposal generation instruction.

[0091] Note that the optimizer 8 may use the production cost instead of the production evaluation index to determine whether a correction to the production plan is necessary. That is, the optimizer 8 may determine whether the production cost is consistent with the target production cost. In this case, the optimizer 8 may omit the calculation of the production evaluation index (step 814).

[0092] As in Fig. 45, upon receiving the correction proposal generation instruction from the optimization device 8, the production plan generation device 4 generates a plurality of proposals for correcting the production plan using the round-robin scheme (step S420). It is assumed that N (N ≥ 2) correction proposals are generated. Fig. Figure 65 shows an example of production plan correction suggestion information where N suggestions for a correction to the production plan are specified. Details of Fig. 65 are described in more detail below.

[0093] Subsequently, the processes from step S421 to step S825 are performed for each correction suggestion. That is, the processes from step S421 to step S825 are repeated N times.

[0094] Specifically, the production plan generation device 4 generates an i-th new production plan based on an i-th (i is arbitrary from 0 to N) correction proposal (step S421).

[0095] Information that specifies the new production plan is called new production plan information.

[0096] The new production plan information differs from that in Fig. 13 production plan information is only in numerical values, and the format is the same as in Fig. 13 production plan information is identical.

[0097] Furthermore, the production plan generation device 4 generates an i-th new production facility operation plan based on the i-th new production plan (step S422).

[0098] Information specifying the new production facility operation plan is called new production facility operation plan information.

[0099] The new production plant operating plan information differs from that in Fig. 21 production plant operation plan information only in the numerical values, and the format is the same as in Fig. 21 production plant operating plan information is identical.

[0100] Further, the production plan generation means 4 generates an i-th new utility facility operation plan based on the i-th new production facility operation plan (step S423).

[0101] Information specifying the new utility operation plan is referred to as new utility operation plan information.

[0102] The new production plant operating plan information differs from that in Fig. 24 shows the utility operation plan information only in numerical values, and the format is the same as in Fig. 24 is identical to the utility operating plan information shown.

[0103] In addition, the production plan generation device 4 calculates an i-th new total amount of consumption resources to be consumed in the production facilities 1 and the supply facility 3 based on the i-th new production facility operation plan and the i-th new supply facility operation plan (step S424).

[0104] Information specifying the new total amount of resources to be consumed in Production Facility 1 and Supply Facility 3 is referred to as new consumption resource information.

[0105] The new consumption resource information differs from that in Fig. 25 consumption resource information is only in the numerical values, and the format is the same as in Fig. 25 shown consumption resource information is identical.

[0106] In addition, the production plan generation device 4 calculates an i-th new total amount of environmental pollution emission amounts in the production facilities 1 and the supply facility 3 based on the i-th new production facility operation plan and the i-th new supply facility operation plan (step S425).

[0107] Information indicating the new total amount of environmental impact emission amounts in Production Facility 1 and Supply Facility 3 is referred to as new environmental impact information.

[0108] The new environmental impact information differs from that in Fig. 25 environmental impact information is presented only in numerical values, and the format is the same as in Fig. 25 is identical to the environmental impact information presented.

[0109] Then, the production plan generation device 4 transmits the i-th new production facility operation plan information, the i-th new supply facility operation plan information, the i-th new consumption resource information, and the i-th new environmental load information to the optimization device 8 (step S426).

[0110] Then, the optimization means 8 receives from the production plan generation means 4 the i-th new production facility operation plan information, the i-th new supply facility operation plan information, the i-th new consumption resource information, and the i-th new environmental load information (step S821).

[0111] Then, the optimization means 8 transmits the i-th new production facility operation plan information, the i-th new supply facility operation plan information, and the i-th new consumption resource information to the supply facility operation plan generation means 7 (step S822).

[0112] Then, the supply facility operation plan generation means 7 receives from the optimization means 8 the i-th new production facility operation plan information, the i-th new supply facility operation plan information, and the i-th new consumption resource information (step S721).

[0113] Next, the provisioning plant operation plan generation device 7 generates an i-th new PV power generation plan based on weather forecast information (step S722). Note that step S722 may be omitted. In this case, in step S724 explained below, the provisioning plant operation plan generation device 7 uses the immediately previously generated PV power generation plan.

[0114] In addition, the supply facility operation plan generation means 7 generates an i-th new EV operation plan based on the i-th new production facility operation plan information and the i-th i-th new supply facility operation plan information (step S723).

[0115] In addition, the provisioning facility operation plan generation means 7 generates an i-th new energy accumulation plan, an i-th new electric discharge plan, and an i-th new reference plan based on the i-th new consumption resource information, the i-th new PV power generation plan, and the i-th new EV operation plan (step S724).

[0116] In addition, the provisioning facility operation plan generation means 7 generates an i-th new provisioning facility operation plan based on the i-th new consumption resource information, the i-th new PV power generation plan, the i-th new energy accumulation plan, the i-th new electric discharge plan, and the i-th new reference plan (step 725).

[0117] Information specifying the new deployment facility operation plan is referred to as new deployment facility operation plan information.

[0118] The new deployment facility operating plan information differs from that in Fig. 35 shows the deployment facility operation plan information only in numerical values, and the format is the same as in Fig. 35 is identical to the deployment facility operating plan information.

[0119] Next, the provisioning facility operation plan generation means 7 transmits the i-th new provisioning facility operation plan information to the optimization means 8 (step S726).

[0120] The optimization means 8 receives the i-th new provisioning facility operation plan information from the provisioning facility operation plan generation means 7 (step S821).

[0121] Then, the optimizer 8 calculates the i-th new production cost based on the i-th new production facility operation plan information, the i-th new supply facility operation plan information, the i-th new consumption resource information, the i-th new environmental load information, and the i-th new supply facility operation plan information (step S823).

[0122] Next, the optimizer 8 calculates an i-th new production evaluation index, which is an index value of the i-th new production cost (step S824).

[0123] The optimizer 8 next determines whether all production plan correction proposals have been tested (step S825). That is, the optimizer 8 determines for each N correction proposal whether a production evaluation index has been calculated.

[0124] If not all correction suggestions have been tested, the processes from step S421 are repeated for an (i+1)th correction suggestion.

[0125] If, however, all correction suggestions have been tested, the optimization device 8 selects a proposal for correcting the production plan with a minimum production evaluation index (step S826).

[0126] Subsequently, the production plants 1 are controlled with a new production plan that corresponds to the correction proposal selected by the optimization device 8. In addition, the renewable energy supply plants 5 are controlled with a new supply plant operating plan that corresponds to the new production plan.

[0127] Note that the optimizer 8 may use the production cost instead of the production evaluation index to select a correction proposal. That is, the optimizer 8 may select a production plan correction proposal with minimal production cost. In this case, the optimizer 8 may omit the calculation of the production evaluation index (step 824).

[0128] In this way, in the present embodiment, when the optimization unit 8 determines that a correction of the production plan is necessary, the production plan generation unit 4 generates a production plan correction proposal. Then, using the production plan based on the generated correction proposal and the PV power generation plan generated based on the weather forecast, the supply facility operation plan generation unit 7 generates a new energy accumulation plan, a new electrical discharge plan, and a new supply plan. Furthermore, the supply facility operation plan generation unit 7 generates a new supply facility operation plan by considering the new energy accumulation plan, the new electrical discharge plan, and the new supply plan.Furthermore, the optimization device 8 calculates a production evaluation index using the new supply facility operation plan, and selects any correction suggestion from the plurality of correction suggestions based on the production evaluation index. Note that the optimization device 8 selecting any correction suggestion from the plurality of correction suggestions is equivalent to the optimization device 8 determining, for each correction suggestion, whether the production plan should be corrected by following the correction suggestion.

[0129] In addition, an example is described here in which the optimizer 8 selects a correction proposal with a minimum production evaluation index from the plurality of correction proposals generated using the round-robin scheme.

[0130] Instead, the production plan generation device 4 may generate one correction suggestion at a time, and the optimization device 8 may determine whether the production evaluation index based on the correction suggestion matches the target value each time a correction suggestion is generated by the production plan generation device 4. That is, the optimization device 8 may perform step S815 after step S824 to determine whether the new production evaluation index matches the target value. In this case, if the new production evaluation index matches the target value, the optimization device 8 selects its corresponding correction suggestion.On the other hand, if the new production evaluation index does not agree with the target value, the optimization device 8 executes step S817 and issues an instruction to generate another proposal for correcting the production plan to the production plan generation device 4.

[0131] In the round-robin scheme, a correction proposal to be included in the production plan can only be selected after all correction proposals have been generated and the production evaluation indices for all correction proposals have been calculated. In contrast, in this scheme, a correction proposal to be included in the production plan can be selected early. ***Details of Production Plan Generation Facility 4***

[0132] Next, details of the production plan generation device 4 are explained.

[0133] Fig. 2 illustrates an example of a hardware structure of the production plan generation device 4 according to Embodiment 1.

[0134] As in Fig. As shown in Figure 2, the production plan generation device 4 includes a control unit 41, a main memory 42, a working memory 43, a communication unit 44, and an input unit 45. Note that the production plan generation device 4 also includes a power supply (not shown) serving as a driving power source.

[0135] The control unit 41 controls the production plan generation device 4.

[0136] The control unit 41 may be a processor, such as a CPU (Central Processing Unit). The control unit 41 may also be an integrated circuit, such as an FPGA (Field Programmable Gate Array), LSI (Large Scale Integration), or ASIC (Application Specific Integrated Circuit). The control unit 41 may also be a combination of a processor and an integrated circuit.

[0137] It should be noted that the control unit 41, which is a subordinate concept of a processor and an integrated circuit, may be referred to as a “processing circuit”.

[0138] In the present embodiment, an example will be described in which the control unit 41 is a processor that executes a program. That is, the control unit 41 executes a production plan generation program 421 stored in the main memory 42. Details of the production plan generation program 421 will be further explained below.

[0139] The control unit 41 controls the main memory 42, the working memory 43, the communication unit 44 and the input unit 45 and executes the production plan generation program 421 to generate a production plan.

[0140] In the main memory 42, various programs to be executed by the control unit 41, data to be referred to when the control unit 41 executes various programs, data generated as a result of execution of each program by the control unit 41, and the like are stored.

[0141] For example, the production plan generation program 421 is stored in the main memory 42.

[0142] The main memory 42 is, for example, a non-volatile memory such as a flash memory, a ROM (Read Only Memory), a hard disk, a hard disk drive or a memory card reader / writer.

[0143] The main memory 43 is a storage device that the control unit 41 can directly access when executing a process of the program. Various programs and data stored in the main memory 42 are copied and temporarily stored in the main memory 43.

[0144] The main memory 43 is, for example, a volatile memory, such as RAM (Random Access Memory).

[0145] It should be noted that the control unit 41 executes the program by temporarily storing, in the working memory 43, the program normally stored in the main memory 42, and reading the program from the working memory 43.

[0146] The communication unit 44 includes a receiver that receives data and a transmitter that sends data.

[0147] The communication unit 44 performs communication with an external device by using the receiver and the transmitter.

[0148] The input unit 45 receives input from a user. The input unit 45 is, for example, a keyboard, a mouse, a touchpad, or a touch panel with a display function.

[0149] Next, an example of a functional structure of the production plan generating device 4 according to the present embodiment will be explained.

[0150] Fig. Figure 3 shows the example of the functional structure of the production plan generation device 4.

[0151] In Fig. 3, for example, an information input unit 451 receives, using the input unit 45, an input of necessary information for the production plan based on order data from a user of the production plan generation device 4.

[0152] The order data displays the order details of a customer. More specifically, the order data specifies how many lots (number of production batches) and pieces (production quantity) of which items (models) are to be produced and by when (production delivery time).

[0153] The necessary information for the production plan defines the information required to generate a production plan that takes into account the order specified in the order data.

[0154] Further, when generation of a proposal for correcting the production plan is required, the information input unit 451 receives an input of the production start time interval from the user of the production plan generating device 4 using the input unit 45. Details of the production start time interval information will be explained later.

[0155] The information required for the production plan is described here.

[0156] The information required for the production plan includes information about a model, a production delivery time, a number of production batches, and a production quantity specified by the order data. Furthermore, the information required for the production plan includes information about the earliest production-enabling time, the production start time, and the production-enabling line. The earliest production-enabling time is the earliest time at which production of an item specified by the order data can start within a period surrounding the production delivery time. The production start time is a time at which production of the item starts. The production-enabling line is a production line capable of producing the item.For example, if the production of an item X is possible on both a production line Y and a production line Z, the production-enabling lines of item X are production line Y and production line Z.

[0157] Parameters as change targets (hereinafter, change parameters) in an instruction unit 815 described below are the following three.

[0158] The first parameter is the production quantity of each model for each production line.

[0159] The second parameter is a production sequence. If the production of two or more models is scheduled on the same production line within the delivery time, the specification unit 815 can change the production sequence of the models.

[0160] Furthermore, the third parameter is the production start time. If the production completion time (total production time) for all scheduled models is earlier than the delivery time, the specification unit 815 can change the production start time.

[0161] In the present embodiment, these three parameters are treated as discrete values. Note that the production quantity and production start time may be treated as continuous values.

[0162] The control unit 41 carries out the Fig. 2 shows the production plan generation program 421.

[0163] Fig. 3 schematically shows a state in which the control unit 41 executes the production plan generation program 421.

[0164] The production plan generation program 421 includes programs that fulfill the functions of a production plan generation unit 411, a production facility operation plan generation unit 412, a communication control unit 413, a utility facility operation plan generation unit 414, and a resource load calculation unit 415.

[0165] Hereinafter, for the convenience of description, the execution of the programs that fulfill the functions of the production plan generation unit 411, the production facility operation plan generation unit 412, the communication control unit 413, the utility facility operation plan generation unit 414, and the resource load calculation unit 415 by the control unit 41 will be described as operations by the production plan generation unit 411, the production facility operation plan generation unit 412, the communication control unit 413, the utility facility operation plan generation unit 414, and the resource load calculation unit 415.

[0166] Note that the production plan generation unit 411, the production facility operation plan generation unit 412, the communication control unit 413, the utility facility operation plan generation unit 414, and the resource load calculation unit 415 to be executed by the control unit 41 each correspond to a "correction unit." Furthermore, the process to be performed by the production plan generation unit 411, the production facility operation plan generation unit 412, the communication control unit 413, the utility facility operation plan generation unit 414, and the resource load calculation unit 415 corresponds to a "correction process."

[0167] The production plan generation unit 411 executes step S411 of Fig. 44 and step S420 and step S421 of Fig. 45 out.

[0168] Specifically, the production plan generation unit 411 generates a production plan based on the information necessary for the production plan and the production facility information.

[0169] The production facility information is stored in advance in a master database 431. Details of the production facility information will be explained later.

[0170] The production plan generation unit 411 acquires the production facility information from the master database 431. Then, the production plan generation unit 411 generates a production plan based on the order data acquired by the information input unit 451 and the production facility information obtained from the master database 431.

[0171] The production plan generation unit 411 outputs production plan information indicating the production plan to the production facility operation plan generation unit 412. The production plan generation unit 411 further causes the production plan information to be stored in the master database 431. As described above, the production plan information is information stored in Fig. 13 are shown as examples.

[0172] Further, when the production plan generation unit 411 receives a correction suggestion generation instruction from the optimizer 8 via the communication control unit 413, it generates a plurality of suggestions for correcting the production plan using the round-robin scheme based on the correction suggestion generation instruction. The correction suggestion generation instruction specifies a change parameter to be considered in the correction suggestion. The production plan generation unit 411 generates a correction suggestion based on the change parameter specified in the correction suggestion generation instruction. In the correction suggestion generation instruction, for example, "production quantity" is specified as a change parameter to be considered in the correction suggestion.When “production quantity” is specified in the correction suggestion generation instruction, the production plan generation unit 411 generates a plurality of correction suggestions for changing the production quantity of any item.

[0173] The production plan generation unit 411 sets a correction suggestion number i for each correction suggestion. Here, it is assumed that the production plan generation unit 411 generates N correction suggestions. In this case, the correction suggestion number i takes any value from 0 to N. In the following, representations such as an i-th correction suggestion, the i-th production plan information, the i-th production facility information, and so on can be used. It is assumed that the correction suggestion number i is set to the i-th correction suggestion, the i-th production plan information, and the i-th production facility information, respectively.

[0174] Specifically, the production plan generation unit 411 generates an i-th production plan for each correction proposal by referring to the information necessary for the production plan and the production facility information. The production plan generation unit 411 outputs the i-th production plan information, in which the i-th production plan is specified, to the production facility operation plan generation unit 412. The production plan generation unit 411 further causes the production plan information to be stored in the master database 431.

[0175] The production plant operation plan generation unit 412 executes step S412 of Fig. 44 and step S422 of Fig. 45 out.

[0176] Specifically, the production facility operation plan generation unit 412 generates an i-th production facility operation plan for each unit time based on the i-th production plan information and the i-th production facility information generated by the production plan generation unit 411.

[0177] The production facility operation plan generation unit 412 outputs i-th production facility operation plan information, in which the i-th production facility operation plan is specified, to the utility facility operation plan generation unit 414. Furthermore, the production facility operation plan generation unit 412 causes the i-th production facility operation plan information to be stored in a production facility operation plan database 432. As described above, the production facility operation plan information is information stored in Fig. 21 are shown as examples.

[0178] Further, when the i-th production plan information is generated by the production plan generation unit 411, the production facility operation plan generation unit 412 generates an i-th production facility operation plan based on the i-th production plan information and the i-th production facility information.

[0179] The production facility operation plan generation unit 412 outputs i-th production facility operation plan information, in which the i-th production facility operation plan is specified, to the utility facility operation plan generation unit 414. Furthermore, the production facility operation plan generation unit 412 causes the i-th production facility operation plan information to be stored in the production facility operation plan database 432.

[0180] The utility operation plan generation unit 414 executes step S413 of Fig. 44 and step S423 of Fig. 45 out.

[0181] Specifically, the utility facility operation plan generation unit 414 generates an i-th utility facility operation plan for each time unit based on the i-th production facility operation plan information and the utility facility information. The utility facility operation plan is an operation plan of utility facility 3.

[0182] The utility information is stored in advance in a master database 431. Details of the utility information will be explained later.

[0183] The utility facility operation plan generation unit 414 acquires the utility facility information from the master database 431, and then generates an i-th utility facility operation plan based on the i-th production facility operation plan information acquired by the production facility operation plan generation unit 412 and the utility facility information acquired from the master database 431.

[0184] The utility operation plan generation unit 414 outputs the i-th production facility operation plan information and the i-th utility operation plan information indicating the i-th utility operation plan to the resource load calculation unit 415. Furthermore, the utility operation plan generation unit 414 causes the i-th utility operation plan information to be stored in a utility operation plan database 433. As described above, the utility operation plan information is information stored in Fig. 24 are shown as examples.

[0185] Further, when i-th production facility operation plan information is generated by the production facility operation plan generation unit 412, the utility facility operation plan generation unit 414 generates an i-th utility facility operation plan based on the i-th production facility operation plan information and utility facility information.

[0186] The utility operation plan generation unit 414 outputs the i-th production facility operation plan information and the i-th utility operation plan information indicating the i-th utility operation plan to the resource load calculation unit 415. Furthermore, the production facility operation plan generation unit 412 causes the i-th utility operation plan information to be stored in the utility operation plan database 433.

[0187] The resource load calculation unit 415 executes step S415 and step S416 of Fig. 44 and step S425 and step S426 of Fig. 45 out.

[0188] Specifically, the resource load calculation unit 415 calculates a total amount of resources to be consumed in the production facilities 1 and the supply facility 3 based on the i-th production facility operation plan information and the i-th supply facility operation plan information. Then, the resource load calculation unit 415 causes i-th consumption resource information indicating the calculated total amount of resources to be stored in a resource load database 434.

[0189] Furthermore, the resource load calculation unit 415 calculates a total amount of environmental pollution emission in the production facilities 1 and the supply facility 3 based on the i-th production facility operation plan information and the i-th supply facility operation plan information. Then, the resource load calculation unit 415 causes i-th environmental pollution information indicating the total amount of environmental pollution emission to be stored in the resource load database 434.

[0190] As described above, the consumption resource information and the environmental impact information are information that is Fig. 25 are shown as examples.

[0191] Furthermore, when the i-th utility facility operation plan information is generated by the utility facility operation plan generation unit 414, the resource load calculation unit 415 generates i-th consumption resource information and i-th environmental load information based on the production facility operation plan information and the i-th utility facility operation plan information. Then, the resource load calculation unit 415 causes the i-th consumption resource information and the i-th environmental load information to be stored in the resource load database 434.

[0192] The communication control unit 413 carries out communication via the communication unit 44 with the production control device 2, the supply system 3 and the optimization device 8.

[0193] Specifically, the communication control unit 413 reads the production facility operation plan information from the production facility operation plan database 432 via the production facility operation plan generation unit 412. Then, the communication control unit 413 transmits the read production facility operation plan information to the production control device 2 and the optimization device 8.

[0194] Furthermore, the communication control unit 413 reads the utility operation plan information from the utility operation plan database 433 via the utility operation plan generation unit 414. Then, the communication control unit 413 transmits the read utility operation plan information to the utility 3 and the optimization device 8.

[0195] Furthermore, the communication control unit 413 reads the consumption resource information and the environmental load information from the resource load database 434 via the resource load calculation unit 415. Then, the communication control unit 413 transmits the read consumption resource information and environmental load information to the optimization device 8.

[0196] The communication control unit 413 further receives a correction suggestion generation instruction from the optimization device 8.

[0197] Upon receiving a correction suggestion generation instruction from the optimization device 8, the communication control unit 413 outputs the correction suggestion generation instruction to the production plan generation unit 411.

[0198] Further, upon receiving a correction suggestion generation instruction from the optimization device 8, the communication control unit 413 transmits the i-th production facility operation plan information, the i-th supply facility operation plan information, the i-th consumption resource information, and the i-th environmental load information to the optimization device 8. ***Details of the Provisioning Facility Operation Plan Generation Facility 7***

Note that the provisioning facility operation plan generation device 7 also includes a power supply (not shown) serving as a driving power source.

[0202] The control unit 71 controls the provisioning facility operation plan generation device 7.

[0203] The control unit 71 may be a processor, such as a CPU. The control unit 71 may also be an integrated circuit, such as an FPGA, an LSI, or an ASIC. The control unit 71 may also be a combination of a processor and an integrated circuit.

[0204] It should be noted that the control unit 71, which is a subordinate concept of a processor and an integrated circuit, may be referred to as a “processing circuit.”

[0205] In the present embodiment, an example will be described in which the control unit 71 is a processor that executes a program. That is, the control unit 71 executes a provisioning facility operation plan generation program 721 stored in the main memory 72. Details of the provisioning facility operation plan generation program 721 will be further explained below.

[0206] The control unit 71 controls the main memory 72, the working memory 73, the communication unit 74 and the input unit 75 and executes the provisioning facility operation plan generation program 721 to generate a provisioning facility operation plan.

[0207] In the main memory 72, various programs to be executed by the control unit 71, data to be referred to when the control unit 71 executes various programs, data generated as a result of execution of each program by the control unit 71, and the like are stored.

[0208] For example, the provisioning facility operation plan generation program 721 is stored in the main memory 72.

[0209] The main memory 72 is, for example, a non-volatile memory such as a flash memory, a ROM, a hard disk, a hard disk drive, or a memory card reader / writer.

[0210] The main memory 73 is a storage device that the control unit 71 can directly access when executing a process of the program. Various programs and data stored in the main memory 72 are copied and temporarily stored in the main memory 73.

[0211] The main memory 73, for example, is a volatile memory, such as RAM (Random Access Memory).

[0212] It should be noted that the control unit 71 executes the program by temporarily storing, in the working memory 73, the program normally stored in the main memory 72, and reading the program from the working memory 73.

[0213] The communication unit 74 includes a receiver that receives data and a transmitter that sends data.

[0214] The communication unit 74 performs communication with an external device by using the receiver and the transmitter.

[0215] The input unit 75 accepts input from a user. The input unit 75 is, for example, a keyboard, a mouse, a touchpad, or a touch panel with a display function.

[0216] Next, an example of a functional structure of the provisioning facility operation plan generation means 7 according to the present embodiment will be explained.

[0217] Fig. 5 shows the example of the functional structure of the provisioning facility operation plan generation device 7.

[0218] In Fig. 5, for example, an input unit 751 receives an input of weather forecast information from a user of the deployment facility operation plan generation device 7 using the input unit 75.

[0219] The weather forecast information provides a weather forecast for the area where Production Facilities 1 is located. The weather forecast information is, for example, time series data that provides a weather forecast per hour.

[0220] The control unit 71 carries out the Fig. 4, executes the provisioning facility operation plan generation program 721.

Then, the supply facility operation plan generation unit 713 outputs the i-th PV power generation plan information corresponding to the i-th PV power generation plan correction proposal to the EV operation plan generation unit 712.

[0230] Furthermore, the power generation plan generation unit 711 causes the i-th PV power generation plan information to be stored in the power generation plan database 731.

Furthermore, the EV operation plan generation unit 712 causes the i-th EV operation plan information to be stored in an EV operation plan database 732.

[0237] The provisioning facility operation plan generation unit 713 executes step S714 of Fig. 44 and step S724 of Fig. 45 out.

[0238] Specifically, the provisioning facility operation plan generation unit 713 generates a provisioning operation plan based on the PV power generation plan information, the EV operation plan information, the production facility operation plan information, the supply facility operation plan information, and the consumption resource information acquired from the optimization device 8 via the communication control unit 714.

As described above, the provisioning facility operation plan information is information stored in Fig. 35 are shown as examples.

[0240] Furthermore, when the i-th new production facility operation plan information, the i-th supply facility operation plan information, and the i-th consumption resource information are received from the communication control unit 714, the supply facility operation plan generation unit 713 generates an i-th proposal for correcting the supply facility operation plan. Then, the supply facility operation plan generation unit 713 causes the i-th supply facility operation plan information corresponding to the i-th proposal for correcting the supply facility operation plan to be stored in the supply facility operation plan database 733.

[0241] The communication control unit 714 performs communication via the communication unit 74 between the feed control device 6 and the optimization device 8.

[0245] Further, the communication control unit 714 reads the deployment facility operation plan information from the deployment facility operation plan database 733 via the deployment facility operation plan generation unit 713. Then, the communication control unit 714 transmits the read i-th deployment facility operation plan information to the optimization device 8. ***Details of Optimization Device 8***

[0246] Next, details of the optimization device 8 are explained.

[0247] Fig. 6 illustrates an example of a hardware structure of the optimization device 8 according to Embodiment 1.

[0248] As in Fig. As shown in Figure 6, the optimization device 8 includes a control unit 81, a main memory 82, a working memory 83, a communication unit 84, and an input unit 85. It should be noted that the optimization device 8 also includes a power supply (not shown) that serves as a driving power source.

[0249] The control unit 81 controls the optimization device 8.

[0250] The control unit 81 may be a processor, such as a CPU. The control unit 81 may also be an integrated circuit, such as an FPGA, an LSI, or an ASIC. The control unit 81 may also be a combination of a processor and an integrated circuit.

[0251] It should be noted that the control unit 81, which is a subordinate concept of a processor and an integrated circuit, may be referred to as a “processing circuit.”

[0252] In the present embodiment, an example will be described in which the control unit 81 is a processor that executes a program. That is, the control unit 81 executes an optimization program 821 stored in the main memory 82. Details of the optimization program 821 will be further explained below.

[0253] The control unit 81 controls the main memory 82, the working memory 83 and the communication unit 84 and executes the optimization program 821.

[0254] In the main memory 82, various programs to be executed by the control unit 81, data to be referred to when the control unit 81 executes various programs, data generated as a result of execution of each program by the control unit 81, and the like are stored.

[0255] For example, the optimization program 821 is stored in the main memory 82.

[0256] The main memory 82 is, for example, a non-volatile memory such as a flash memory, a ROM, a hard disk, a hard disk drive, or a memory card reader / writer.

[0257] The main memory 83 is a storage device that the control unit 81 can directly access when executing a process of the program. Various programs and data stored in the main memory 82 are copied and temporarily stored in the main memory 83.

[0258] For example, the main memory 83 is a volatile memory, such as RAM.

[0259] It should be noted that the control unit 81 executes the program by temporarily storing, in the working memory 83, the program normally stored in the main memory 82, and reading the program from the working memory 83.

[0260] The communication unit 84 includes a receiver that receives data and a transmitter that sends data.

[0261] The communication unit 84 performs communication with an external device by using the receiver and the transmitter.

[0262] The input unit 85 accepts input from a user. The input unit 85 is, for example, a keyboard, a mouse, a touchpad, or a touch panel with a display function.

[0263] Next, an example of a functional structure of the optimization device 8 according to the present embodiment will be explained.

[0264] Fig. Figure 7 shows an example of the functional structure of the optimization device 8.

[0265] In Fig. 7, a weighting factor input unit 851 receives an input of a weighting factor from a user of the optimization device 8 using the input unit 85.

[0266] The weighting factor is used to calculate a production evaluation index.

[0267] The control unit 81 carries out the Fig. 6 shows the optimization program 821.

[0268] Fig. 7 schematically shows a state in which the control unit 81 executes the optimization program 821.

[0269] The optimization program 821 includes programs that fulfill the functions of a communication control unit 811, a production cost calculation unit 812, a production evaluation index calculation unit 813, a determination unit 814, and the instruction unit 815.

[0270] Hereinafter, for the convenience of description, the execution of the programs that fulfill the functions of the communication control unit 811, the production cost calculation unit 812, the production evaluation index calculation unit 813, the determination unit 814, and the instruction unit 815 by the control unit 81 will be described as operations by the communication control unit 811, the production cost calculation unit 812, the production evaluation index calculation unit 813, the determination unit 814, and the instruction unit 815.

[0271] Note that the process to be performed by the determination unit 814 corresponds to a “determination process”.

[0272] Furthermore, the communication control unit 811, the production cost calculation unit 812, the production evaluation index evaluation unit 813, and the instruction unit 815 to be executed by the control unit 81 may each correspond to a "correction unit." Furthermore, the process to be performed by the communication control unit 811, the production cost calculation unit 812, the production evaluation index evaluation unit 813, and the instruction unit 815 corresponds to a "correction process."

[0273] The production cost calculation unit 812 executes step S813 of Fig. 44 out.

[0274] Specifically, the production cost calculation unit 812 calculates the production cost based on the production facility operation plan information, the supply facility operation plan information, the consumption resource information, the environmental load information, and the supply facility operation plan information.

[0275] The production cost calculation unit 812 calculates production costs for each of the expense items, such as energy purchase costs, labor costs, environmental pollution costs, and so on.

[0276] The production cost calculation unit 812 outputs production cost information indicating the production cost for each expense item to the production evaluation index calculation unit 813.

[0277] The production cost calculation unit 812 further causes the production cost information to be stored in a production cost database 832. Furthermore, the production cost calculation unit 812 causes the production facility operation plan information, the supply facility operation plan information, the consumption resource information, the environmental impact information, and the supply facility operation plan information to be stored in a master database 831.

[0278] The production evaluation index calculation unit 813 executes step S814 of Fig. 44 out.

[0279] Specifically, the production evaluation index calculation unit 813 calculates a production evaluation index, which is an index value of production costs.

[0280] The production evaluation index calculation unit 813 acquires the weighting factor from the weighting factor input unit 851. Then, for each expense item of the production cost, the production evaluation index calculation unit 813 multiplies the amount of the cost by the corresponding weighting factor. Then, the production evaluation index calculation unit 813 sums the multiplication values ​​for each expense item to acquire a production evaluation index.

[0281] The production evaluation index calculation unit 813 outputs production evaluation index information in which the production evaluation index is indicated to the determination unit 814.

[0282] In addition, the production evaluation index calculation unit 813 causes the production evaluation index information to be stored in a production evaluation index database 833.

[0283] The determination unit 814 executes step S815 of Fig. 44 out.

[0284] That is, the determination unit 814 determines whether the production evaluation index indicated in the production evaluation index information agrees with a target value.

[0285] The determination unit 814 acquires target value information specifying the target value from a target value database 834.

[0286] Then, the determination unit 814 determines whether the production evaluation index indicated in the production evaluation index information agrees with a target value indicated in the target value information.

[0287] The determination unit 814 outputs determination result information indicating the production evaluation index information and the determination result to the instruction unit 815.

[0288] The instruction unit 815 executes step S816 or step S817 of Fig. 44 out.

[0289] Specifically, when the production evaluation index agrees with the target value as a result of the determination in the determination unit 814, the instruction unit 815 determines that correction of the production plan is not necessary. If it is determined that correction of the production plan is not necessary, the instruction unit 815 approves the production plan generated by the production plan generation device 4.

[0290] When approving the production plan, the instruction unit 815 reads the production facility operation plan information from the master database 831. Then, the instruction unit 815 outputs the read production facility operation plan information to the communication control unit 811.

[0291] On the other hand, if the production evaluation index does not agree with the target value, the instruction unit 815 determines that correction of the production plan is necessary.

[0292] Then, when it is determined that correction of the production plan is required, the instruction unit 815 outputs a correction suggestion generation instruction to the communication control unit 811 to cause the production plan generation device 4 to generate a suggestion for correction of the production plan.

[0293] The correction proposal generation instruction contains a change parameter that must be taken into account in the correction proposal.

[0294] The communication control unit 811 receives the production facility operation plan information, the supply facility operation plan information, the consumption resource information, and the environmental load information from the production plan generation device 4. In addition, the communication control unit 811 outputs the received production facility operation plan information, the supply facility operation plan information, the consumption resource information, and the environmental load information to the production cost calculation unit 812.

[0295] Furthermore, the communication control unit 811 transmits the production facility operation plan information, the supply facility operation plan information, and the consumption resource information to the supply facility operation plan generation device 7.

[0296] The communication control unit 811 also receives the provisioning facility operation plan information from the provisioning facility operation plan generation device 7. The communication control unit 811 outputs the received new provisioning facility operation plan information to the production cost calculation unit 812.

[0297] Further, when it is determined by the instruction unit 815 that correction of the production plan is not required, the communication control unit 811 transmits the production facility operation plan information to the display device 9.

[0298] The communication control unit 811 further transmits a correction suggestion generation instruction from the instruction unit 815 to the production plan generation device 4.

[0299] Furthermore, the communication control unit 811 receives the i-th production facility operation plan information, the i-th supply facility operation plan information, the i-th consumption resource information, and the i-th environmental load information from the production plan generation device 4.

[0300] The communication control unit 811 outputs the received i-th production facility operation plan information, the i-th supply facility operation plan information, the i-th consumption resource information, and the i-th environmental load information to the production cost calculation unit 812.

[0301] In addition, the communication control unit 811 transmits the i-th production facility operation plan information, the i-th supply facility operation plan information, and the i-th consumption resource information to the supply facility operation plan generation device 7.

[0302] The communication control unit 811 further receives the i-th provisioning facility operation plan information from the provisioning facility operation plan generation means 7. The communication control unit 811 outputs the received i-th provisioning facility operation plan information to the production cost calculation unit 812.

[0303] When the i-th production facility operation plan information, the i-th supply facility operation plan information, the i-th consumption resource information, and the i-th environmental load information are received from the communication control unit 811, the production cost calculation unit 812 calculates the i-th production cost based on the i-th production facility operation plan information, the i-th supply facility operation plan information, the i-th consumption resource information, and the i-th environmental load information.

[0304] Then, the production cost calculation unit 812 outputs i-th production cost information in which the i-th production cost is indicated to the production evaluation index calculation unit 813.

[0305] Further, the production cost calculation unit 812 causes the i-th production cost information to be stored in the production cost database 832.

[0306] Further, the production cost calculation unit 812 causes the i-th production facility operation plan information, the i-th supply facility operation plan information, the i-th consumption resource information, the i-th environmental load information, and the i-th supply facility operation plan information to be stored in the master database 831.

[0307] Then, the production evaluation index calculation unit 813 calculates an i-th production evaluation index, which is an index value of the i-th production cost.

[0308] In addition, the production evaluation index calculation unit 813 outputs i-th production evaluation index information in which the i-th production evaluation index is indicated to the instruction unit 815.

[0309] In addition, the production evaluation index calculation unit 813 causes the i-th production evaluation index information to be stored in the production evaluation index database 833.

[0310] Further, upon acquiring the i-th production evaluation index information from the production evaluation index calculation unit 813, the instruction unit 815 causes the acquired i-th production evaluation index information to be stored in a production plan change database 835.

[0311] Further, the instruction unit 815 determines whether all production plan correction proposals have been tested each time it acquires the i-th production evaluation index information. That is, the instruction unit 815 determines whether N pieces of new production evaluation index information have been acquired for N correction proposals. Specifically, the instruction unit 815 determines whether a value i, which is a correction proposal number, matches N. Note that it is assumed that the instruction unit 815 has been notified by the production plan generation unit 411 that the total number of correction proposals is N.

[0312] If not all correction suggestions have been tested, the instruction unit 815 waits to acquire new production evaluation index information for the next correction suggestion.

[0313] On the other hand, if all correction suggestions have been tested, the instruction unit 815 selects production evaluation index information with a minimum production evaluation index.

[0314] Then, the instruction unit 815 reads out production facility operation plan information in which the same correction suggestion number as that of the selected production evaluation index information is set from the master database 831. Then, the instruction unit 815 outputs the read out production facility operation plan information to the communication control unit 811.

[0315] The communication control unit 811 transmits the production facility operation plan information acquired from the instruction unit 815 to the display device 9. ***Description of a concrete example of information and operation***

[0316] Next, an operation example will be described using a concrete example of information for use in the present embodiment.

[0317] It should be noted that the following description assumes that supply system 3 is a compressed air supply system and a water recycling system.

[0318] The compressed air supply system provides compressed air as a resource for the production facilities 1.

[0319] In addition, the water recycling plant provides water as a resource for the production facilities 1. Furthermore, the water for recycling is purified in the water recycling plant after use. **Description of a concrete example of information for use in the production plan generation device 4 and operation of the production plan generation device 4**

[0331] Note that, before the production facility operation plan generation unit 412 generates a production facility operation plan, it is assumed that the production facility information is acquired from the production facilities 1 and stored in the master database 431. Instead, when the production facility operation plan generation unit 412 generates a production facility operation plan, the production facility operation plan generation unit 412 may acquire the production facility information from the production facilities 1 using the communication control unit 413.

The assembly process is the process of assembling components into an article. The testing process is the process of checking whether the quality of a produced article meets certain criteria.

[0339] Fig. 9 represents a sequence of a production process.

[0340] Fig. Figure 9 shows master data of the production process for models A, B, C, and D as a single flow. The production process for models A, B, C, and D starts and runs through the work processes on four different lines and then ends.

[0358] Under the item calculation time unit, a time unit is specified for the production facility operation plan generation unit 412 to calculate a process state of the production process in the production facility 1. The production facility operation plan generation unit 412 generates the production facility operation plan for each time unit.

[0359] The production facility operation plan generation unit 412 generates a production facility operation plan for every 3,600 seconds as shown in Fig. 15. Note that the calculation time unit can be any time other than 3,600 seconds. Note that the calculation time unit can be 7,200 seconds, 10,800 seconds, or the like.

Furthermore, the labor consumption is 1 hour. Furthermore, the cost item for electricity is electricity, and the cost item for labor is labor costs.

[0368] Fig. Figure 20 shows an example of environmental pollutant information for each production process.

[0369] Fig. Figure 20 shows an example of environmental pollutant information in Work 1 process to Work 4 process. It should be noted that the representation in Fig. 20 was partially omitted for reasons of graphic representation.

[0370] As in Fig. As shown in Figure 20, the environmental impact information is composed of a production process, a plant operation, an environmental impact substance, an emission amount, a reduction resource, a consumption amount and a regulation threshold.

[0371] Under the heading Production process, each production process that is included under the heading Production process of Fig. 8. The item Plant operation is the item Plant operation in Fig. 12 specified plant operation is specified. Under the item "polluting substance," a substance is specified as a cause of environmental pollution. Under the item "emission amount," the emission amount of the polluting substance is specified. Under the item "reduction resource," a reduction resource used to reduce emissions of the polluting substance is specified. Under the item "consumption amount," the consumption amount of the reduction resource is specified. Under the item "regulation threshold," the regulatory upper limit for the emission amount of the polluting substance is specified.

[0372] Fig. 13 shows an example of production plan information to be generated by the production plan generation unit 411. As in Fig. As shown in Figure 13, the production plan information consists of a target model, a production process, a production start time, a production delivery time and a production quantity.

[0373] Under the position Target Model, a model to be produced is specified. Under the position Production Process, each production process that is defined under the position Production Process of Fig. 8. The Production Start Time item specifies the time at which each production process starts. The Production Delivery Time item specifies the completion deadline for the production of a target model item. The Production Quantity item specifies the production quantity of the target model.

[0374] The production plan generation unit 411 generates production plan information based on order data and production facility information ( Fig. 8 to Fig. 12, Fig. 14 to Fig. 20).

[0375] Fig. 21 illustrates an example of production facility operation plan information to be generated by the production facility operation plan generation unit 412.

[0376] For reasons of graphic representation, the representation in Fig. 21 partially omitted.

[0377] The production plant operation plan information of Fig. 21 are composed of an operating time, a production model for each work process, a production quantity and a plant operation.

[0378] Under the operating time position, the time for each Fig. 15 shown time unit is given.

[0379] Under the Production Model position, a model name of a model that is to be produced in Production Plant 1 in a time unit starting from the operating time specified in the same line is specified.

[0380] Under the Production Quantity item, a production quantity of the model to be produced in Production Plant 1 in the time unit starting from the operating time specified in the same line is specified.

[0381] The item Plant Operation indicates an operation to be carried out by production plant 1 in the time unit starting from the operating time specified in the same line.

[0382] The production facility operation plan generation unit 412 generates the production facility operation plan information shown in Fig. 21, based on the production plan information ( Fig. 13) and the production plant information ( Fig. 8 to Fig. 12, Fig. 14 to Fig. 20).

[0383] Specifically, the production facility operation plan generation unit 412 generates for each production process included in the process information of Fig. 8, the production plant operation plan information from Fig. 21, based on the plant operating information from Fig. 12, the productivity information from Fig. 10, the process operation information from Fig. 11 and the production plan information from Fig. 13.

[0384] Here, an example is explained in which the production facility operation plan generation unit 412 generates production facility operation plan information from Fig. 21 for “Work 1” Fig. 8 generated.

[0385] Note that in the present embodiment, it is assumed that the time required to transport a produced item between production processes is included in the production processing time in each production process. It is also assumed that the transport of a produced item between production processes occurs hourly. Furthermore, it is assumed that the item produced in each production process is transported to the next production process.

[0386] The production plant operation plan generation unit 412 acquires from the process operation information Fig. 11 “Start”, “Work 1 Process”, “Standby”, “Process End” and “Stop” as plant operation for “Work 1”.

[0387] For “Work 1”, the production plant operation plan generation unit 412 acquires from the plant operation information Fig. 12 “1 hour” as start operation time, “1 hour” as end process operation time and acquires “0 hour” as stop operation time.

[0388] The production plant operation plan generation unit 412 further acquires for “Work 1” from the productivity information from Fig. 10 “Item A” as one item and “14.4 seconds / piece” as production capacity.

[0389] Furthermore, the production facility operation plan generation unit 412 acquires for “Model A” and “Work 1” from the production plan information from Fig. 13 “2021 / 04 / 05 09:00” as production start time and “6,000 pieces” as production quantity.

[0390] Then, since "1 hour" is required as the start operation time and the production start time for "Work 1" is "2021 / 04 / 05 09:00", the production facility operation plan generation unit 412 determines that the start of "Work 1" begins at "2021 / 04 / 05 08:00". Further, since the production quantity of "Item A" is "6,000 pieces" and the production capacity of "Item A" is "14.4 seconds / piece", the production facility operation plan generation unit 412 determines that the "Work 1 process" of "Work 1" requires 24 hours (6,000 pieces × 14.4 seconds ÷ 3,600 seconds = 24 hours). Thus, the production facility operation plan generation unit 412 determines that a work process for 250 pieces (6,000 pieces ÷ 24 hours = 250 pieces) is performed per hour. Furthermore, the production facility operation plan generation unit 412 determines that "Work 1" is completed at "2021 / 04 / 06 9:00," which is 24 hours after "2021 / 04 / 05 09:00."This shows that each “production quantity of labor 1” from “2021 / 04 / 05 09:00” to “2021 / 04 / 05 08:00” in . Fig. 21 is "250 pieces". It should be noted that "2021 / 04 / 06 09:00", which is the completion time of "Work 1", is within a range of "2021 / 04 / 06 09:30", which is the "production delivery time" in the production plan of Fig. 13 is.

[0391] The production facility operation plan generation unit 412 determines that “final process” of “work 1” starts at “2021 / 04 / 06 09:00”.

[0392] In addition, since “1 hour” is required as the operation time of final process for “Work 1”, the production facility operation plan generation unit 412 determines that “stop” of “Work 1” is performed at “2021 / 04 / 06 10:00”.

[0393] The production facility operation plan generation unit 412 also performs a similar process for “Work 2”, “Work 3” and “Work 4”.

[0394] The production facility operation plan generation unit 412 displays the values ​​acquired by the above-explained process in the production facility operation plan information Fig. 21 fixed.

[0395] With the above-mentioned operation, the production facility operation plan generation unit 412 generates the production facility operation plan information from Fig. 21.

[0396] Next, utility information is collected using Fig. 22 to Fig. 24 explained.

[0397] The utility information is composed of utility operation schedule information and utility resource information.

[0398] The utility operation schedule information specifies an operation schedule of utility 3.

[0399] The provisioning resource information specifies a resource to be consumed in the utility facility 3.

[0400] Note that it is assumed that the utility information (utility facility operation schedule information, provision resource information) is acquired from the utility facility 3 and stored in the master database 431 before the resource load calculation unit 415 generates a utility facility operation plan. Instead, when the resource load calculation unit 415 generates a utility facility operation plan, the utility facility operation plan generation unit 414 may acquire utility information from the utility facility 3 using the communication control unit 413.

[0401] Fig. Figure 22 shows an example of utility operation schedule information.

[0402] More precisely, Fig. 22 shows an example of supply plant operating schedule information of a compressed air supply plant.

[0403] As in Fig. As shown in Figure 22, the utility facility operation schedule information is composed of an operation time, a supply quantity, and a facility operation.

[0404] Under the item Operating time, the same time is indicated as that which is shown under the item Operating time in Fig. 21 is specified.

[0405] The item “supply quantity” indicates the quantity of compressed air that is to be supplied by supply system 3 to production system 1 in a unit of time starting from the operating time specified in the same line.

[0406] The item plant operation indicates an operation to be carried out by the supply system 3 in the time unit from the operating time specified in the same line.

[0407] The “compression process” specified under the item Plant Operation is an operation for compressing air for supply to Production Plant 1.

[0408] Fig. 23 shows an example of supply resource information More precisely, Fig. Figure 23 shows an example of supply resource information of the compressed air supply system.

[0409] As in Fig. As shown in Figure 23, the supply resource information is composed of a supply facility, a facility operation, a resource, a consumption quantity and an expenditure item.

[0410] The name of supply system 3 is given under the position “supply system”.

[0411] The Plant Operation item covers the plant operation that is carried out in Fig. 22 in the section on plant operation.

[0412] Under the item Resource, a resource is specified which is to be used in the supply system 3 when the supply operation is carried out.

[0413] The item consumption quantity indicates the quantity of a resource that is to be consumed in the supply system 3 when the system is operated.

[0414] The name is specified in the resource cost administration under the expense item.

[0415] Compressed air is not referred to as a resource here because compressed air is a resource that does not incur any costs, i.e. it has no expense item, and therefore does not need to be considered as a consumption amount.

[0416] Fig. 24 illustrates an example of utility operation plan information to be generated by the utility operation plan generation unit 414.

[0417] More precisely, Fig. 24 shows an example of supply system operating plan information of the compressed air supply system.

[0418] As in Fig. As shown in Figure 24, the utility operating status information is composed of a utility, an operating time, a supply quantity, a facility operation, and a utility resource.

[0419] The supply system item refers to the supply system which is located in Fig. 23 under the item supply system.

[0420] Under the position operating time, the operating time of Fig. 22 specified operating time.

[0421] Under the position provision quantity, the quantity under the position provision quantity of Fig. 22 specified provision quantity.

[0422] The position Plant Operation covers the Fig. 22 plant operation specified under the item plant operation.

[0423] Under the item Utility Resource, the resource specified under the item Resource and the quantity specified under the item Consumption in Fig. 23 specified consumption quantity.

[0424] Fig. 25 illustrates an example of consumption resource information and environmental load information to be calculated by the resource load calculation unit 415.

[0425] In Fig. 25, the consumption resource information and the environmental impact information are combined. Unlike in Fig. 25, the consumption resource information and the environmental impact information may each be different information elements.

[0426] In Fig. 25 Values ​​specified under the operating time and consumption resource items correspond to the consumption resource information. Furthermore, values ​​under the operating time and environmental impact items correspond to the environmental impact information.

[0427] It should be noted that the representation in Fig. 25 was partially omitted for reasons of graphic representation.

[0428] In Fig. 25, the same time is indicated under the position Operating time as that which is indicated under the position Operating time in Fig. 21 is specified.

[0429] The consumption resource item specifies the resource quantity to be consumed in each work process and the total resource quantity across all work processes. Specifically, the consumption hypocenter is composed of the energy consumption amount in each work process, the total value of the energy consumption amounts, the compressed air quantity in each work process, the total value of the compressed air quantities, the working hours in each work process, and the total value of the working hours.

[0430] The environmental impact item specifies the amount of environmental impact emissions in each work process and the total amount of environmental impact emissions. Specifically, the environmental impact item consists of the amount of CO2 emissions in each work process and the total amount of CO2 emissions.

[0431] Furthermore, based on the production resource information of Fig. 16 to Fig. 19 and the environmental impact information from Fig. 20, the resource load calculation unit 415 generates the consumption resource information (item of consumption resource) and the environmental load information (item of environmental load) of Fig. 25.

[0432] Here, an example is explained in which the resource load calculation unit 415 calculates the consumption resource information and the environmental load information in Fig. 25 for “Work 1” by Fig. 8 generated.

[0433] For “Work 1”, the resource load calculation unit 415 acquires from the production resource information Fig. 16 for each plant operation, the value explained under the item resource, the value explained under the item consumption quantity and the value explained under the item expenditure item.

[0434] Then, using the values ​​obtained from the production resource information of Fig. 16, the resource load calculation unit 415 generates the consumption resource information (consumption resource item) of Fig. 25.

[0435] Here, a process for deriving a value for “Work-1-Energy-Consumption Amount” from Fig. 25 described.

[0436] Then, the resource load calculation unit 415 extracts, for each operation time of the production facility, operation plan information from Fig. 21 the value of “Work 1 Plant Operation” of Fig. 21.

[0437] Furthermore, the resource load calculation unit 415 extracts for under “plant operation” in Fig. 16 the line in which a value corresponding to the extracted value is explained.

[0438] In addition, the resource load calculation unit 415 extracts the value “consumption amount” for “electricity” explained in the extracted line.

[0439] Next, the resource load calculation unit 415 multiplies the value “Consumption Quantity” by the value of “Work 1 Production Quantity” from Fig. 21.

[0440] Further, the resource load calculation unit 415 extracts the value of “utility resource” at the same operation time as that of the utility operation plan information in Fig. 24.

[0441] Then, the resource load calculation unit 415 sets an addition value of the multiplication value and the extracted value “utility resource” in “work-1 energy consumption amount” at the same operation time in Fig. 25 fixed.

[0442] For example, for “2021 / 04 / 05 09:00” in Fig. 21, the resource load calculation unit 415 multiplies the value (“0.0463”) of the “consumption amount” of “electricity” of the “work 1 process” of “work 1” in Fig. 16 with the value (“250”) of the “Labor 1 Production Quantity” in Fig. 21. In addition, the resource load calculation unit 415 adds the value (“20 kWh”) of the “utility resource” of “2021 / 04 / 05 09:00” in Fig. 24 to the multiplication value. Then, the resource load calculation unit 415 sets the addition value in “Work-1 Energy Consumption Amount” of “2021 / 04 / 05 09:00” in Fig. 25 fixed.

[0443] The resource load calculation unit 415 also performs a similar process for “Work 2”, “Work 3” and “Work 4”.

[0444] Then, the resource load calculation unit 415 sums the energy consumption amounts for "Work 1," "Work 2," "Work 3," and "Work 4" for each operation time. Furthermore, the resource load calculation unit 415 sets the total value under the item "Total Energy Consumption Amount" in Fig. 25 fixed.

[0445] The resource load calculation unit 415 also performs a similar operation for the compressed air amount and the working hours.

[0446] In addition, the resource load calculation unit 415 for “Work 1” acquires, for each facility operation, the value under the item “Environmental pollution substance”, the value under the item “Emission amount”, the value under the item “Reduction resource”, and the value under the item “Consumption amount” from the environmental pollution information of Fig. 20.

[0447] Furthermore, using the values ​​obtained from the environmental pollution information of Fig. 20, the resource load calculation unit 415 generates a value of environmental load information (environmental load element) of Fig. 25.

[0448] Here, a process is described to derive a value for “Work 1 CO2 emission amount” from Fig. 25 described.

[0449] Then, the resource load calculation unit 415 extracts, for each operation time of the production facility, operation plan information from Fig. 21 the value of “Work 1 Plant Operation” of Fig. 21.

[0450] Furthermore, the resource load calculation unit 415 extracts under “plant operation” in Fig. 20 the line in which a value corresponding to the extracted value is explained.

[0451] In addition, the resource load calculation unit 415 extracts the value of “emission amount” explained in the extracted line.

[0452] Next, the resource load calculation unit 415 multiplies the extracted value of “Emission Amount” by the value of “Work 1 Production Quantity” from Fig. 21.

[0453] Then, the resource load calculation unit 415 sets the multiplication value in “Work 1 CO2 emission amount” at the same operation time in Fig. 25 fixed.

[0454] For example, for “2021 / 04 / 05 09:00” in Fig. 21, the value (“0.0488” of the “Emission Amount” of “Work-1 Process” of “Work 1” in Fig. 20 with the value (“250”) of the “Work 1 Production Quantity” in Fig. 21. Then, the resource load calculation unit 415 sets the multiplication value in “Work 1 CO2 emission amount” at “2021 / 04 / 05 09:00” in Fig. 25 fixed.

[0455] The resource load calculation unit 415 also performs a similar process for “Work 2”, “Work 3” and “Work 4”.

[0456] Then, for each operation time, the resource load calculation unit 415 sums the CO2 emission amounts for "Work 1," "Work 2," "Work 3," and "Work 4." Furthermore, the resource load calculation unit 415 sets the total value under the item "CO2 emission total amount" in Fig. 25 fixed. **Description of a concrete example of information for use in the provisioning facility operation plan generation device 7 and operation of the provisioning facility operation plan generation device 7**

[0457] Next, information for use in the provisioning facility operation plan generation device 7 will be explained.

[0458] In the present embodiment, it is assumed that the renewable energy supply system 5 has a Fig. 26 has the structure shown.

[0459] As in Fig. As shown in Figure 26, Renewable Energy Facility 5 contains four employee shuttle EVs. There are also four EV chargers and dischargers. A single storage battery is also present. Furthermore, a single energy generation facility is present.

[0460] Renewable energy supply facility 5 provides electrical energy, which is acquired through self-generated energy, for the employee shuttle EVs, the production facilities 1 and the supply facility 3.

[0461] Furthermore, in a unit time in which the energy supply amount is insufficient, the renewable energy supply facility 5 supplies electric energy (purchased energy) purchased from an energy supplier, which is an auxiliary energy supply facility, to the employee shuttle EVs, the production facility 1, and the supply facility 3.

[0462] Fig. 27 to Fig. 29 each show an example of renewable energy supply facility information.

[0463] The renewable energy supply plant information consists of maximum energy information, PV plant information and accumulator battery information.

[0464] It is assumed that the renewable energy supply facility information (maximum energy information, PV system information, accumulator battery information) is acquired from the renewable energy supply facility 5 and stored in the master database 730 before the power generation plan generation unit 711 generates a power generation plan. Instead, when the power generation plan generation unit 711 generates a power generation plan, the power generation plan generation unit 711 may acquire the renewable energy supply facility information 5 using the communication control unit 714.

[0465] Fig. Figure 27 shows an example of maximum energy information.

[0466] The maximum energy information indicates a maximum energy that can be provided by the renewable energy supply facility 5. In the present embodiment, the maximum energy of the renewable energy supply facility 5 is 500 kW.

[0467] Fig. Figure 28 shows an example of PV system information.

[0468] As in Fig. As shown in Figure 28, the PV system information consists of building installation area, module energy generation capacity, module installation area, number of modules and total energy generation capacity.

[0469] Fig. Figure 29 shows an example of accumulator battery system information.

[0470] As in Fig. As shown in Figure 29, the accumulator-battery system information consists of accumulator-battery capacity and charge / discharge efficiency.

[0471] Fig. 30 shows an example of weather forecast information.

[0472] The Fig. The weather forecast information input unit 751 shown in Fig. 5 inputs weather forecast information.

[0473] As in Fig. As shown in Figure 30, the weather forecast information consists of a time corresponding to the time unit and a weather forecast at any time.

[0474] Fig. Figure 31 shows an example of PV energy generation plan information.

[0475] The PV power generation plan information specifies a PV power generation plan generated by the power generation plan generation unit 711.

[0476] The PV energy generation plan information consisted, as in Fig. 31, consists of an operating time and a PV energy generation quantity.

[0477] Using the weather forecast information ( Fig. 30) and the PV system information ( Fig. 28), the power generation plan generation unit 711 predicts a PV power generation amount for each unit time to generate the PV power generation plan.

[0478] Under the item Operating time, the same time is indicated as that which is shown under the item Operating time in Fig. 21 is specified.

[0479] Under the item PV power generation amount, the PV power generation amount predicted by the power generation plan generation unit 711 is indicated.

[0480] Fig. Figure 32 shows an example of EV operating plan information.

[0481] In the EV operation plan information, an EV operation plan generated by the EV operation plan generation unit 712 is specified. The EV operation plan generation unit 712 generates an EV operation plan based on the production facility operation plan information ( Fig. 21) and the utility operating plan information ( Fig. 24).

[0482] As in Fig. 32, the EV operation plan information is composed of the EV number, the plant arrival year / month / day, the plant arrival time, the plant departure time / month / day, the plant departure time, the planned arrival batch rate, and the planned departure batch rate.

[0483] It should be noted that the batch rate [%] of the “scheduled arrival batch rate” and the “scheduled departure batch rate” is calculated using Expression 1. Charge rate[%]=EV remaining capacity[kWh]÷EV maximum capacity[kWh]

[0484] The term “plant” also includes the plants that contain both the production facilities 1 and the supply facility 3.

[0485] Fig. Figure 33 shows an example of request-side energy consumption information.

[0486] As in Fig. 33, the demand-side energy consumption quantity information is composed of an operating time, an energy consumption quantity in the production facility, an energy consumption quantity at the supply facility, and a demand-side energy consumption quantity.

[0487] Under the item Operating time, the same time is indicated as that which is shown under the item Operating time in Fig. 21 is specified.

[0488] The energy consumption quantity in production plant 1 is specified under the item Energy consumption quantity in production plant.

[0489] The energy consumption quantity in supply system 3 is specified under the item Energy consumption quantity in the supply system.

[0490] Under the item demand-side energy consumption quantity, a total value of the energy consumption quantity in the production plant and the energy consumption quantity in the supply plant is specified.

[0491] The provisioning facility operation plan generation unit 713 uses the value of “energy consumption amount” of the consumption resource information ( Fig. 25) as “energy consumption amount in the production plant” of Fig. 33. Furthermore, the supply facility operation plan generation unit 713 uses the value of “supply facility resource” of the supply facility operation plan information ( Fig. 24) as “energy consumption amount in the supply system” of Fig. 33.

[0492] Fig. Figure 34 shows an example of EV charging / discharging amount information.

[0493] As in Fig. 34, the EV charge / discharge amount information is composed of an operating time and an EV charge / discharge amount.

[0494] The EV Charge / Discharge Amount item shows the total charge / discharge amounts of the four EVs. A positive EV charge / discharge amount represents discharging, while a negative EV charge / discharge amount represents charging.

[0495] The provisioning facility operation plan generation unit 713 generates EV charging / discharging amount information based on the EV operation plan information ( Fig. 32).

[0496] Fig. Figure 35 shows an example of deployment facility operating plan information.

[0497] As in Fig. 35, the provisioning facility operation plan information is composed of an operation time, a demand-side energy consumption amount, a PV energy generation amount, a PV energy feed-in amount, an accumulator battery charging / discharging amount, an EV charging / discharging amount, and a demand coverage / demand amount of energy purchase.

[0498] Under the item Operating time, the same time is indicated as that which is shown under the item Operating time in Fig. 21 is specified.

[0499] The provisioning facility operation plan generation unit 713 generates provisioning facility operation plan information with the following operation.

[0500] As a value of “request-side energy consumption amount,” the provisioning facility operation plan generation unit 713 uses a value of “request-side energy consumption amount” of the request-side energy consumption amount information ( Fig. 33).

[0501] Further, as a value of “PV power generation amount”, the provisioning facility operation plan generation unit 713 uses a value of “PV power generation amount” of the PV power generation plan information ( Fig. 31).

[0502] In addition, the provisioning plant operation plan generation unit 713 decides a value of “PV energy feed-in amount” with the following process.

[0503] When “demand-side energy consumption amount ≥ PV energy generation amount”, the provisioning plant operation plan generation unit 713 uses a value of “PV energy generation amount” as a value of “PV energy feed-in amount”.

[0504] On the other hand, when “demand-side energy consumption amount < PV energy generation amount”, the provisioning plant operation plan generation unit 713 uses a value of “demand-side energy consumption amount” as a value of “PV energy feed-in amount”.

[0505] In addition, the provisioning facility operation plan generation unit 713 decides a value of “accumulator battery charge-discharge amount” with the following process.

[0506] When “demand-side energy consumption amount < PV energy generation amount,” the provisioning facility operation plan generation unit 713 calculates a value of “accumulator battery charge / discharge amount” with Expression 2.

[0507] On the other hand, if “demand-side energy consumption amount ≥ PV energy generation amount”, if “(battery remaining amount × charge / discharge efficiency) ≥ (request-side energy consumption amount - PV energy generation amount)”, the provisioning facility operation plan generation unit 713 calculates a value of “battery charging / discharging amount” using Expression 3. On the other hand, if “(battery remaining amount × charge / discharge efficiency) < (request-side energy consumption amount - PV energy generation amount)”, the provisioning facility operation plan generation unit 713 calculates a value of “battery charging / discharging amount” using Expression 4.

[0508] It should be noted that “Charge / Discharge Efficiency” is specified in the accumulator battery system information ( Fig. 29). Accumulator battery charge / discharge amount = (demand-side energy consumption amount − PV energy generation amount) × charge / discharge efficiency Accumulator battery charge / discharge amount = (demand-side energy consumption amount − PV energy generation amount) Accumulator-battery charge / discharge amount = Accumulator-battery remaining amount × Charge / discharge efficiency

[0509] Further, as a value of “EV charging / discharging amount”, the provisioning facility operation plan generation unit 713 uses a value of “EV charging / discharging amount” of the EV charging / discharging amount information ( Fig. 34).

[0510] In addition, the supply facility operation plan generation unit 713 calculates a value of “demand coverage / demand quantity of energy purchase” with Expression 5. Demand coverage / demand quantity of energy purchase = demand-side energy consumption amount - PV energy feed-in amount - accumulator battery discharge amount - EV charging / discharging amount

[0511] The changes in the amount of energy for each unit of time, which are subject to the Fig. The items “Accumulator Battery Charge / Discharge Amount” and “EV Charge / Discharge Amount” shown in Figure 35 correspond to the energy accumulation plan and the electrical discharge plan.

[0512] In addition, changes in the amount of energy for each time unit, which are specified under the item “Demand coverage / demand quantity of energy purchase”, correspond to the supply plan. **Description of a concrete example of information for use in the optimization device 8 and operation of the optimization device 8**

[0513] Next, information on usage in the optimization device 8 is explained.

[0514] Fig. Figure 36 shows an example of electric energy unit price information.

[0515] As in Fig. As shown in Figure 36, the electric energy unit price information is composed of a time zone, an electric energy unit price, and comments.

[0516] In Fig. Figure 36 shows an example where 24 hours are divided into six time zones. The electrical energy unit price indicates a unit price at which electrical energy is purchased from the auxiliary energy supply facility in each time zone.

[0517] The electric energy unit price information is stored in the master database 831.

[0518] Fig. Figure 37 shows an example of demand coverage / demand energy purchasing cost information.

[0519] As in Fig. As shown in Figure 37, the demand coverage / demand energy purchasing cost information is composed of an operating time, an energy purchasing amount and energy purchasing costs.

[0520] Under the item Operating time, the same time is indicated as that which is shown under the item Operating time in Fig. 21 is specified.

[0521] Under the item Energy Purchase Amount, the value under the item Demand Coverage / Demand Quantity of Energy Purchase of the supply facility operating plan information ( Fig. 35).

[0522] The production cost calculation unit 812 multiplies the value of the energy purchase amount by the value of the electric energy unit price of the electric energy unit price information ( Fig. 36) to acquire a value of the energy purchase costs.

[0523] Fig. Figure 38 shows an example of unit labor cost information.

[0524] As in Fig. As shown in Figure 38, the unit labor cost information is composed of a working hour zone type, unit labor costs, and a working hour zone.

[0525] In the example of Fig. 38 has six working time zones: four weekday time zones, Saturday, Sunday, and a public holiday. The names of the six working time zones are listed under the "Working Time Zone Type" item.

[0526] Unit labor costs show the labor costs for an employee per hour for each working time zone type.

[0527] The unit labor cost information is stored in the production evaluation index calculation unit 813.

[0528] Fig. Figure 39 shows an example of information on the number of workers.

[0529] As in Fig. As shown in Figure 39, the information on the number of workers is composed of a production process and the number of workers.

[0530] Under the heading Production Process, each production process from Work 1 to Work 4 is specified.

[0531] The number of workers item indicates the number of workers required in each production process.

[0532] The information about the number of workers is stored in the master database 831.

[0533] Fig. Figure 40 shows an example of CO2 emission unit cost information.

[0534] As in Fig. As shown in Figure 40, the CO2 unit cost information is composed of an electricity-CO2 conversion and CO2 emission unit costs.

[0535] The item Electricity-CO2 conversion indicates a value for the conversion of energy consumption into a quantity of CO2 emissions.

[0536] The required CO2 costs per kilogram are stated under the item CO2 emission unit costs.

[0537] The CO2 emission unit cost information is stored in the master database 831.

[0538] Fig. Figure 41 shows an example of production cost information.

[0539] As in Fig. As shown in Figure 41, the production cost information consists of a target, electricity, air, labor costs, CO2 and a total.

[0540] In the example of Fig. Figure 41 shows the production costs of total demand coverage / demand. The production costs of total demand coverage / demand represent the total costs incurred in production facilities 1, supply facility 3, and supply facility operating plan generation facility 7.

[0541] The electricity item shows the electricity costs to be taken into account in the production facilities 1, the supply facility 3 and the provision facility operating plan generation facility 7.

[0542] The air costs to be taken into account in the production facilities 1, the supply facility 3 and the supply facility operating plan generation facility 7 are specified under the item air.

[0543] The item “Wage costs” shows the wage costs to be taken into account in the production facilities 1, the supply facility 3 and the supply facility operating plan generation facility 7.

[0544] Under the item CO2, the environmental pollution costs to be taken into account in the production plant 1, the supply plant 3 and the supply plant operating plan generation facility 7 are indicated.

[0545] Under the heading Total Amount, the total amount of the values ​​for electricity, air, labor costs and CO2 is given.

[0546] The production cost calculation unit 812 acquires a value for “electricity” based on the demand coverage / demand energy purchase cost information ( Fig. 37).

[0547] The production cost calculation unit 812 acquires a value for “labor costs” based on the unit labor cost information ( Fig. 38) and information on the number of workers ( Fig. 39).

[0548] The production cost calculation unit 812 acquires a value for “CO2” based on the environmental pollution information ( Fig. 25), the demand coverage / demand energy purchasing cost information ( Fig. 37) and the CO2 emission unit cost information ( Fig. 40).

[0549] The production evaluation index calculation unit 813 calculates a production evaluation index based on the production cost information ( Fig. 41).

[0550] Specifically, the production evaluation index calculation unit 813 calculates a production evaluation index with the following operation.

[0551] In the present embodiment, the production evaluation indices are classified into productivity, energy efficiency and environmental impact.

[0552] The production evaluation index of productivity is the total sum of the values ​​obtained by multiplying the labor cost in each production process by the load time and dividing the multiplication value by the production quantity (Expression 6).

[0553] The production evaluation index of energy efficiency is the total sum of the values ​​obtained by multiplying the energy consumption cost in each production process by the load time and dividing the multiplication value by the load time (Expression 7).

[0554] The production evaluation index of environmental pollution is obtained by dividing the environmental pollution cost in each production process by the load time (Expression 8).

[0555] Here, the load time is obtained by subtracting the planned non-operating time from the plant operating time based on the current production plan, as shown in Expression 9.

[0556] It should be noted that only labor costs are used to calculate a production evaluation index of productivity. In addition to labor costs, a consumption resource other than energy consumption, such as material costs, can also be used to calculate a production evaluation index of productivity. Furthermore, a production evaluation index of a consumption resource other than energy consumption, such as material costs, can be calculated. (Productivity)=∑(Labor costs)×(Load time) / (Production quantity) (Energy efficiency)=∑(Energy consumption costs)×(Load time) / (Production quantity) (Environmental impact)=∑(Environmental impact costs)×(Load time) / (Production quantity) (Load time)=(operating time)−(planned non-operating time)

[0557] In addition, the production evaluation index calculation unit 813 generates a final production evaluation index from the production evaluation indices of energy efficiency, productivity, and environmental load through the following Expression 10. Note that the value of the production evaluation index obtained from Expression 10 is smaller when the production plan is more suitable. (Production Evaluation Index) = w1 × (Productivity) + w2 × (Energy Efficiency) + w3 × (Environmental Impact) w1, w2, w3: Weighting factor (user setting) (w1+w2+w3 = 1)

[0558] The weighting factors w1, w2, and w3 can be set by the user depending on the situation, such as the environment of the production site, the evaluation priority level, the character arrangement of terms, etc. Note that all weighting factors add up to 1.

[0559] Fig. 42 illustrates an example of production evaluation index information to be generated by the production evaluation index calculation unit 813.

[0560] As in Fig. As shown in Figure 42, the production evaluation index information consists of a target, productivity, energy efficiency and environmental impact.

[0561] It should be noted that in the example of Fig. 42 a production evaluation index is given which was calculated with w1 = 0.1, w2 = 0.05 and w3 = 0.85.

[0562] The determination unit 814 acquires target value information from the target value database 834.

[0563] Fig. Figure 43 shows an example of target value information.

[0564] The target information specifies a target value for the production evaluation index.

[0565] The determination unit 814 compares the value of the “target value” with the production evaluation index.

[0566] The determination unit 814 compares the production evaluation index (total amount) of the production evaluation index information ( Fig. 42) and the target value information to determine whether a correction to the production plan is necessary.

[0567] If the production evaluation index (total amount) of the production evaluation index information ( Fig. 42) is equal to or less than the target value, the determination unit 814 determines that correction of the production plan is not necessary. On the other hand, if the production evaluation index (total amount) of the production evaluation index information ( Fig. 42) is greater than the target value, the determination unit 814 determines that a correction of the production plan is necessary.

[0568] It should be noted that the target value can be set arbitrarily by the user of the optimization device 8.

[0569] When the determination unit 814 determines that correction of the production plan is required as explained above, the instruction unit 815 instructs the production plan generation device 4 to generate a proposal for correction of the production plan with the round robin scheme.

[0570] Fig. 65 shows an example of the production plan correction suggestion information generated by the production plan generation unit 411.

[0571] As in Fig. As shown in Figure 65, the production plan correction proposal information consists of a correction proposal number, a production process, a target model, a production start time, a production delivery time, and a production quantity. Fig. For the sake of simplicity, Figure 65 shows a proposal for correcting the production plan, which only concerns model B and model D, which are to be manufactured in work 2.

[0572] Under the position Correction proposal number, a number is specified that corresponds to the number of correction proposals generated by the production plan generation unit 411 (in Fig. 65 shows that N correction suggestions were generated).

[0573] Under the Target Model position, a model is specified as a correction target.

[0574] Under the Production Process item, a production process is specified as a correction target. Under the Production Process item, any production process that is listed under the Production Process item of Fig. 8 is specified.

[0575] Under the Production Start Time item, a suggestion for correcting the production start time is given. This means that under the Production Start Time item, a suggestion for correcting the time when the production process specified under the Production Process item starts is given.

[0576] Under the Production End Time item, a suggestion for correcting the production end time is given. This means that under the Production End Time item, a suggestion for correcting the time is given when the production process specified under the Production Process item ends.

[0577] Under the "Production Quantity" item, a proposal for correcting the production quantity is given. This means that under the "Production Quantity" item, a proposal for correcting the production quantity of the model specified under the "Target Model" item is given.

[0578] The production plan generation unit 411 generates a correction proposal so that it corresponds to a change parameter specified by the correction proposal generation instruction. In the correction proposal generation instruction, at least one of the parameters "production quantity," "production sequence," and "production start time" is specified as a change parameter.

[0579] In the correction proposal generation instruction, it is assumed that “production quantity”, “production sequence” and “production start time” are specified as change parameters.

[0580] Since “production quantity” is specified as a change parameter, the production plan generation unit 411 generates a correction proposal for changing the production quantity of Model B and Model D.

[0581] In addition, since “production sequence” is specified as a change parameter, the production plan generation unit 411 generates a correction proposal for changing the production sequence of Model B and Model D.

[0582] In addition, since “production start time” is specified as a change parameter, the production plan generation unit 411 generates a correction proposal for changing the production start time of Model B and Model D.

[0583] In the production plan of the production plan information of Fig. At Work 13, it is planned that 2,800 units of Model B will be produced. It is also planned that 290 units of Model D will be produced at Work 2.

[0584] The production plan generation unit 411 generates a correction proposal to change the original plan in which 800 units of model B are produced and 290 units of model D are produced at work 2. That is, the production plan generation unit 411 changes the production quantity of model B in a range of 0 to 799 and the production quantity of model D in a range of 0 to 279. Then, the production plan generation unit 411 generates N correction proposals covering all combinations of the production quantity of model B and the production quantity of model D at work 2.

[0585] For the correction proposal number: 1 in Fig. 65, the production quantity of model B and the production quantity of model D are both 0 units. Furthermore, for correction proposal number: K, the production quantity of model B and the production quantity of model D are each 50 units. Furthermore, for correction proposal number: N, the production quantity of model B is 799 units and the production quantity of model D is 289 units.

[0586] Furthermore, it is in the production plan of the production plan information of Fig. 13 It is planned that at work 2 model D will be produced after model B has been produced.

[0587] The production plan generation unit 411 generates a correction proposal to change the original plan in which model D is produced after model B is produced. That is, the production plan generation unit 411 generates a correction proposal to produce model D first and then produce model B.

[0588] For the correction proposal number: K in Fig. 65 shows a correction proposal in which model D is produced first and model B is produced after production of model D has been completed.

[0589] Furthermore, in the production plan, the production plan information of Fig. 13 the production start time at work 2 “2021 / 04 / 05 09:00”.

[0590] The production plan generation unit 411 generates a correction proposal to change the original plan, in which work 2 starts at "2021 / 04 / 05 09:00." This means that the production plan generation unit 411 generates a correction proposal in which work 2 starts at a different time.

[0591] For the correction proposal number: N in Fig. 65 a correction suggestion is given where work 2 starts at “2021 / 04 / 05 03:00”.

[0592] When generating a correction proposal to change the production start time, the production plan generation unit 411 first calculates a range that allows the production start time of work 2 to be changed (changeable production start time range).

[0593] The start time of the modifiable production start time period is the earliest possible production time. The end time of the modifiable production start time period is the time obtained by subtracting the production time from the production delivery time. For example, if the delivery time of Model B and Model D is "2021 / 04 / 06 08:30" and the total production time of Model B and Model D is 20 hours, "2021 / 04 / 05 12:30," obtained by subtracting 20 hours from the delivery time "2021 / 04 / 06 08:30," is the end time of the modifiable production start time period.

[0594] Next, the production plan generation unit 411 refers to the production start time interval information. The production start time interval information specifies a unit by which the production start time is changed by the production plan generation unit 411. Specifically, the time unit, such as "1 hour" or "30 minutes," is specified in the production start time interval information.

[0595] Here, for convenience of description, the changeable production start time range of work 2 is "2021 / 04 / 05 03:00" to "2021 / 04 / 05 09:00". In this case, if "1 hour" is specified in the production start time interval information, the production plan generation unit 411 generates a proposal for correcting the production start time of work 2 in units of 1 hour, such as "2021 / 04 / 05 03:00", "2021 / 04 / 05 04:00", "2021 / 04 / 05 05:00" ... "2021 / 04 / 05 08:00". On the other hand, when “30 minutes” is specified in the production start time interval information, the production plan generation unit 411 generates a proposal for correcting the production start time of work 2 in units of 30 minutes, such as “2021 / 04 / 05 03:00”, “2021 / 04 / 05 03:30”, “2021 / 04 / 05 04:00”, “2021 / 04 / 05 04:30”, ... “2021 / 04 / 05 08:00”, “2021 / 04 / 05 08:30”.

[0596] In this way, the production plan generation unit 411 generates correction proposals so that all combinations of the change parameters specified in the correction proposal generation instruction are covered.

[0597] Then, the production plan generation unit 411 generates a new production plan for each correction proposal.

[0598] To simplify the description, it is assumed here that Model B and Model D can also be produced in all work processes other than that of Work 2 (Work 1, Work 3, and Work 3). This means that the producible line of Model B and Model D includes Work 1, Work 3, and Work 3.

[0599] For the correction proposal number: 1 in Fig. 65, for example, the number of Model B and Model D to be produced at Work 2 is 0. Thus, the production plan generation unit 411 generates a new production plan in which a total of 800 pieces of Model B are produced at Work 1, Work 3, and Work 3, and 290 pieces of Model D are produced. For the correction suggestion number: K in Fig. 65, the number of pieces of model B and the number of pieces of model D to be produced at work 2 are each 50. Thus, the production plan generation unit 411 generates a new production plan in which a total of 750 pieces of model B are produced at work 1, work 3, and work 3, and 240 pieces of model D are produced.

[0600] Thereafter, as described above, after all correction suggestions have been tested, the instruction unit 815 selects a production plan from which the minimum production evaluation index is acquired. ***Comparison between sequential schema and synchronous schema***

[0601] Next, a comparison will be made between the production plan optimization scheme according to the technique of Patent Literature 1 and a production plan optimization scheme according to the present embodiment.

[0602] Hereinafter, the production plan optimization scheme according to the technique of Patent Literature 1 is referred to as a sequential scheme. Meanwhile, the production plan optimization scheme according to the present embodiment is referred to as a synchronous scheme.

[0603] Fig. Figure 46 shows an example of production plan information after it has been optimized by the sequential scheme. Fig. 46 corresponds to Fig. 13.

[0604] In the sequential scheme, all production processes are carried out in a nighttime time zone with a low unit price of electricity, in an area where no overtime labor costs are incurred when creating a production plan. Thus, in the sequential scheme, it is possible to create a production plan with low electricity costs while simultaneously reducing overtime costs.

[0605] However, in the sequential scheme, the electrical energy supply from the renewable energy supply plant is not taken into account when preparing the production plan.

[0606] Fig. Figure 47 shows an example of production plan information after it has been optimized by the synchronous scheme. Fig. 47 corresponds to Fig. 13.

[0607] That means, Fig. Figure 47 shows the production plan information of a production plan from which a minimum production evaluation index is acquired after generating a production plan correction proposal using the round-robin scheme.

[0608] Fig. 48 shows an example of production plant operation plan information generated based on the production plan information under the Fig. 46 shown sequential scheme.

[0609] That means, Fig. 48 corresponds to Fig. 21.

[0610] Fig. 49 shows an example of consumption resource information and environmental impact information generated based on the production plan information under the Fig. 46 shown sequential scheme.

[0611] That means, Fig. 49 corresponds to Fig. 25.

[0612] Fig. 50 shows an example of production plant operation plan information generated based on the production plan information under the Fig. 47 shown synchronous schema.

[0613] That means, Fig. 50 corresponds to Fig. 21.

[0614] Fig. Figure 51 shows an example of consumption resource information and environmental impact information generated based on the production plan information under the Fig. 47 shown synchronous schema.

[0615] That means, Fig. 51 corresponds to Fig. 25.

[0616] Fig. 52 shows an example of demand-side energy consumption quantity information generated based on the production plan information under the Fig. 46 shown sequential scheme.

[0617] That means, Fig. 52 corresponds to Fig. 33.

[0618] Fig. 53 shows an example of demand-side energy consumption quantity information generated based on the production plan information under the Fig. 47 shown synchronous schema.

[0619] That means, Fig. 53 corresponds to Fig. 33.

[0620] Fig. 54 shows an example of provisioning facility operation plan information generated based on the production plan information under the Fig. 46 shown sequential scheme.

[0621] That means, Fig. 52 corresponds to Fig. 35.

[0622] Fig. 55 shows an example of provisioning facility operation plan information generated based on the production plan information under the Fig. 47 shown synchronous schema.

[0623] That means, Fig. 55 corresponds to Fig. 35.

[0624] Fig. Figure 56 shows an example of demand coverage / demand energy purchasing cost information calculated based on the production plan information under the Fig. 46 shown sequential scheme.

[0625] That means, Fig. 56 corresponds to Fig. 37.

[0626] Fig. Figure 57 shows an example of demand coverage / demand energy purchasing cost information calculated based on the production plan information under the Fig. 47 shown synchronous schema.

[0627] That means, Fig. 57 corresponds to Fig. 37.

[0628] Fig. 58 shows an example of production cost information calculated based on the production plan information under the Fig. 46 shown sequential scheme.

[0629] That means, Fig. 58 corresponds to Fig. 41.

[0630] Fig. 59 shows an example of production cost information generated based on the production plan information under the Fig. 47 shown synchronous schema.

[0631] That means, Fig. 59 corresponds to Fig. 41.

[0632] Fig. 60 shows an example of production evaluation index information calculated based on the production plan information under the Fig. 46 shown sequential scheme.

[0633] That means, Fig. 60 corresponds to Fig. 42.

[0634] Fig. 61 shows an example of production evaluation index information calculated based on the production plan information under the Fig. 47 shown synchronous schema.

[0635] That means, Fig. 61 corresponds to Fig. 42.

[0636] In the sequential scheme, all work processes in a time zone with a low electric energy unit price are carried out without considering the energy supply quantity of the renewable energy supply facility 5, and production in a time zone with a high electric energy unit price is suppressed. As in Fig. 52, the demand-side energy consumption is low in a daytime time zone and high in a nighttime time zone.

[0637] In contrast, the PV energy generation quantity of the renewable energy supply system 5 typically falls more into the daytime time zone, as in Fig. 54. Thus, during the daytime, there is a time zone in which the demand-side energy consumption falls below the PV energy generation. Specifically, the demand-side energy consumption falls below the PV energy generation from "2021 / 4 / 5 14:00" to "2021 / 4 / 5 15:00."

[0638] In these time zones, a surplus amount of PV energy generation accumulates in the accumulator battery from the PV energy generation amount, which exceeds the demand-side energy generation amount. In the example of Fig. 54, the accumulated electrical energy is provided to the request side at “2021 / 4 / 5 20:00” and “2021 / 4 / 5 21:00”.

[0639] Since the charge / discharge efficiency of the accumulator battery is 90%, as shown in Fig. As shown in Figure 29, the amount of electrical energy that can be provided is 81% of the amount of energy generated, which is not efficient when electrical energy is accumulated in the storage battery and then discharged.

[0640] As a result, in the sequential scheme, the demand coverage / demand energy purchasing costs increase, and as in Fig. As shown in Figure 56, the total energy purchasing costs for demand coverage / demand energy amount to 15,602 yen.

[0641] In contrast, in the synchronous scheme, the production plan is optimized taking into account the amount of energy provided by the renewable energy supply facility 5. Thus, in the synchronous scheme, all work processes are carried out in one time zone with a large amount of energy supply from the renewable energy supply facility 5.

[0642] As in Fig. 53, in the synchronous scheme, the demand-side energy consumption amount is high in a daytime time zone and low in a nighttime time zone.

[0643] As explained above, the PV energy generation quantity from the renewable energy supply system 5 typically falls more in the daytime time zone. As in Fig. 55, in the synchronous scheme, the demand-side energy consumption amount during the daytime is higher than the PV energy generation amount.

[0644] In the synchronous scheme, no energy accumulation occurs in the storage battery, and there is no impact on the charging / discharging efficiency of the storage battery. Thus, in the synchronous scheme, it is possible to efficiently supply electrical energy from the renewable energy supply facility 5.

[0645] As a result, the demand coverage / demand energy purchasing costs can be reduced in the synchronous scheme. Specifically, in the synchronous scheme, as shown in Fig. 57, the demand coverage / demand energy purchasing costs can be reduced to a total of 14,625 yen.

[0646] In the synchronous scheme, the demand coverage / demand energy purchasing costs can be reduced by about 6% compared to the sequential scheme.

[0647] Furthermore, in the synchronous scheme, the costs related to CO2 emissions can be reduced by about 15% compared to the sequential scheme.

[0648] Here, the synchronous scheme and the sequential scheme are compared in terms of demand satisfaction / demand-energy purchasing costs and CO2 emissions. A similar comparison can be made for an environmental pollutant such as volatile organic compounds (VOC gas).

[0649] Out of Fig. 60 and Fig. 61 shows that it is also possible for the production evaluation index in the synchronous scheme to acquire a value that is more favourable than that in the sequential scheme, both in terms of energy efficiency and environmental impact. ***Description of the effects of the embodiment***

[0650] In the present embodiment, an energy accumulation plan, an electrical discharge plan, and a supply plan are generated based on a production plan correction proposal and a power generation plan based on a prediction of a state change of the external environment. Then, based on the generated energy accumulation plan, the electrical discharge plan, and the supply plan, a production plan correction proposal to be adopted is selected.

[0651] Thus, according to the present embodiment, even when a power generation facility whose power generation amount fluctuates depending on the state change of the external environment is used as an energy supply source, it is possible to select a production plan including the energy accumulation plan, the electric discharge plan, and the purchase plan that can efficiently utilize fluctuations in the power generation amount.

[0652] Furthermore, in the present embodiment, a correction proposal in which the production cost is minimal or an index value obtained from the production cost is minimal is selected from a plurality of correction proposals. Thus, according to the present embodiment, the production cost can be reduced.

[0653] Furthermore, according to the present embodiment, it is possible to generate a production plan that meets the environmental regulations regarding the amount of carbon dioxide emissions, the amount of VOC gas emissions, the restrictions on the use of electric power, and so on, without reducing the production efficiency. Embodiment 2.

[0654] In Embodiment 1, an example was described in which a proposal for correcting a production plan is generated using the round-robin scheme.

[0655] In the present embodiment, an example in which the number of generations of suggestions for correcting the production plan is reduced will be described.

[0656] In the present embodiment, the differences from Embodiment 1 are mainly described.

[0657] It should be noted that the aspects not described below are similar to those of Embodiment 1. ***Description of the structure***

[0658] Fig. 62 shows an example of a functional structure of the optimization device 8 according to the present embodiment.

[0659] In Fig. 62 are compared to Fig. 7, a learning model generation unit 817 and a learning model database 837 are added.

[0660] The components other than the learning model generation unit 817 and the learning model database 837 are identical to those described in Fig. 7 are shown.

[0661] Like the instruction unit 815 and so on, the learning model generation unit 817 is also integrated into the optimization program 821.

[0662] The learning model generation unit 817 learns the previously corrected production plans and generates a learning model in which the learning results are taken into account.

[0663] The learning model generation unit 817 causes the generated learning model to be stored in the learning model database 837.

[0664] In the present embodiment, correction log information for the previously corrected production plans is stored in the production plan change database 835. The production plan correction log information is composed of pre-correction production plan information, post-correction production plan information, pre-correction order data, and post-correction order data.

[0665] The pre-correction production plan information is production plan information that specifies a production plan before correction (pre-correction production plan).

[0666] The post-correction production plan information is production plan information in which a production plan after correction by following the correction suggestion (post-correction production plan) selected by the instruction unit 815 is specified.

[0667] The pre-correction order data is order data that is used to generate the pre-correction production plan.

[0668] The post-correction order data is order data that is used to generate the post-correction production plan.

[0669] The learning model generation unit 817 acquires the production plan correction log information from the production plan change database 835. Using the acquired production plan correction log information, the learning model generation unit 817 performs machine learning such as reinforcement learning to generate a learning model. The learning model generation unit 817 learns a relationship between a difference between the pre-correction order data and the post-correction order data and a difference between the pre-correction production plan information and the post-correction production plan information. That is, the learning model generation unit 817 learns how the production plan changes when which parameter of the order data is changed and in what way.

[0670] The learning model is a model that serves as a guide for correcting the production plan.

[0671] Note that the learning model generation unit 817 may update the learning model regularly. Furthermore, the learning model database 837 is regularly copied to the main memory 82.

[0672] In the present embodiment, before the learning model generation unit 817 generates a learning model, as in Embodiment 1, the instruction unit 815 causes the production plan generation means 4 to generate a proposal for correcting the production plan with the round robin scheme.

[0673] Each time a correction proposal for the production plan is selected to be accepted, the instruction unit 815 causes the pre-correction production plan information, the post-correction production plan information, the pre-correction order data, and the post-correction order data to be stored in the production plan change database 835 as production plan correction log information.

[0674] After the learning model is generated by the learning model generation unit 817, the instruction unit 815 generates a new production plan using the learning model as a suggestion for correcting the production plan. Then, the instruction unit 815 transmits new production plan information specifying the new production plan to the production plan generation unit 4 via the communication control unit 811.

[0675] In the production plan generation device 4, a new production facility operation plan is generated based on the new production plan. ***Description of how it works***

[0676] Fig. 63 and Fig. 64 each show an example of the operation of the production plan generating means 4, the supply facility operation plan generating means 7 and the optimization means 8 according to the present embodiment.

[0677] Fig. 63 corresponds to Fig. 44. Fig. 64 corresponds to Fig. 45.

[0678] In Fig. 63, steps S411 to S416 for the operation of the production plan generation device 4 are identical to those of Fig. 44. Furthermore, steps S711 to S716 as the operation of the provisioning facility operation plan generating means 7 are identical to those of Fig. 44.

[0679] Furthermore, in the operation of the optimization device 8, steps S811 to S816 are identical to those of Fig. 44.

[0680] In the present embodiment, in step S837, the instruction unit 815 generates a new production plan using the learning model. Then, the communication control unit 811 transmits new production plan information indicating the new production plan to the production plan generation device 4.

[0681] In Fig. 64 are in contrast to Fig. 45 Step S420 and step S421 are omitted. That is, if the production plan generation unit 411 generates neither a correction proposal nor a new production plan, the production facility operation plan generation unit 412 generates a new production facility operation plan in step S422 based on the new production plan information transmitted from the optimization device 8.

[0682] Since the operation from step S423 in the production plan generation device 4 is identical to that in Fig. 45 is identical, a description is omitted.

[0683] Since the functionality in the provisioning system operating plan generation device 7 is also the same as in Fig. 45 is identical, a description is omitted.

[0684] Since in the optimization device 8 the steps S821 to S824 are carried out with the Fig. 45 are identical, a description is omitted.

[0685] In step S845, the instruction unit 815 determines whether generation of a new production plan is required, that is, whether the production evaluation index matches the target value. If generation of a new production plan is not required, that is, if the production evaluation index matches the target value, the instruction unit 815 approves a new production plan in step S846. The instruction unit 815 further causes production plan correction log information to be stored in the production plan change database 835.

[0686] On the other hand, if the production evaluation index does not match the target value and correction of the production plan is required, the instruction unit 815 further generates a new production plan using the learning model in step S847. Then, the communication control unit 811 transmits new production plan information indicating the new production plan to the production plan generation device 4.

[0687] Then, the processes from step S422 are repeated.

[0688] Note that, before generating a learning model, the instruction unit 815 causes the production plan generation device 4 to generate a proposal for correcting the production plan using the round-robin scheme. Instead, the instruction unit 815 may generate a new production plan using a solution search method such as a genetic algorithm or a Lagrange relaxation scheme. Thus, the instruction unit 815 can generate production plan information with a minimum production evaluation index in a finite period of time. ***Description of the effects of the embodiment***

[0689] As described above, in the present embodiment, new production plan information is generated using the learning model acquired through machine learning or reinforcement learning. Therefore, according to the present embodiment, it is possible to generate a production plan with a smaller production evaluation index with a small amount of time and process.

[0690] Embodiments 1 and 2 have been described above, and these two embodiments can be implemented in combination.

[0691] Alternatively, one of these two embodiments may be partially implemented.

[0692] Alternatively, these two embodiments can be partially combined for implementation.

[0693] Furthermore, the structures and operations described in these two embodiments may be changed as needed. ***Additional description of the hardware structure***

[0708] Furthermore, at least a part of the OS is executed by the control unit 81 as a processor.

[0709] While at least part of the OS is executing, the control unit 81 executes the optimization program 821.
