An information processing system (500) determines whether or not there is a need to correct a production plan of a production facility (1) that performs production by receiving power supply from a power generation facility (5) whose power generation amount varies in accordance with a change in the state of an external environment. Furthermore, the information processing system (500) generates a production plan correction case when the production plan needs to be corrected, generates a power storage plan, a discharge plan, and a purchase plan on the basis of the generated production plan correction case and the power generation plan of the power generation facility (5) based on the prediction of the state transition of the external environment, and transmits the power storage plan, the discharge plan, and the purchase plan to the power generation facility (5). On the basis of a power storage plan, a discharge plan, and a procurement plan, whether or not to correct the production plan in accordance with a correction plan of the production plan is determined, the power storage plan being a plan of power storage for the amount of power exceeding the amount of power required when the amount of power generated exceeds the amount of power required, the discharge plan being a plan of discharging the amount of power exceeding the amount of power stored to the production facility (1), and the procurement plan. The purchase plan is a plan for purchasing, from power supply facilities other than the power generation facility (5), the amount of power that is insufficient in the case where the total amount of power, which is the amount of power generated and the amount of power stored, is insufficient with respect to the amount of power required.

Description

Technical Field

[0001] The present invention relates to the correction of production plans. Background Art

[0002] In Japan, China, Europe and the United States, the automation of production equipment is being promoted with the goal of improving manufacturing efficiency. On the other hand, in recent years, legal regulations related to the emission of environmentally harmful substances such as carbon dioxide have become increasingly stringent.

[0003] Currently, in order to comply with legal regulations, the introduction of renewable energy supply equipment as power supply equipment for supplying power to production equipment has begun to be studied. Renewable energy supply equipment includes EV (Electric Vehicle) equipped with solar power generation (hereinafter also referred to as PV (Photovoltaic) power generation) and V2X (Vehicle-to-everything).

[0004] Under such circumstances, it is assumed that the ratio of the power supply amount from the renewable energy supply facility to the power demand amount, which is the power consumption amount of the production facility and the utility facility, becomes high. The utility facility is a facility that supplies resources required for production to the production facility.

[0005] In this way, since it is assumed that the ratio of the power supply from the renewable energy supply equipment to the power demand becomes higher, it is required to strike a balance between the operation of the production equipment and the public service equipment and the operation of the renewable energy supply equipment. By striking a balance in the operation, it is possible to maintain production efficiency and reduce carbon dioxide emissions. In this way, it is possible to cope with legal regulations.

[0006] Patent Document 1 discloses a method of optimizing electricity rates by adjusting a production plan.

[0007] More specifically, in the technology of Patent Document 1, production is performed during the night time period when the unit price of electricity is low based on a predetermined rate plan, thereby optimizing the electricity rate.

[0084] Hereinafter, the embodiment will be described using the drawings. In the following description of the embodiment and the drawings, parts denoted by the same reference numerals represent the same parts or corresponding parts.

[0085] Implementation method 1.

[0086] ***Description of system structure***

[0087] Figure 1 An example of the production planning optimization system 100 according to the first embodiment is shown.

[0088] like Figure 1 As shown, the production plan optimization system 100 includes production equipment 1, a production control device 2, a public service equipment 3, a production plan generating device 4, a renewable energy supply device 5, a supply control device 6, a supply equipment operation plan generating device 7, an optimization device 8, a display device 9 and a network 10.

[0089] In the present embodiment, an example in which the production planning optimization system 100 includes three production facilities 1 is described, but the number of production facilities 1 may be any number.

[0090] Furthermore, in the present embodiment, an example is described in which the production planning optimization system 100 includes one common service device 3 , but the number of common service devices 3 may be plural.

[0091] Furthermore, in the present embodiment, an example is described in which the production planning optimization system 100 includes three renewable energy supply facilities 5 , but the number of the renewable energy supply facilities 5 may be any number.

[0092] In addition, the production plan generating device 4, the supply equipment operation plan generating device 7, and the optimization device 8 are equivalent to the information processing system 500. In addition, the actions performed by the production plan generating device 4, the supply equipment operation plan generating device 7, and the optimization device 8 are equivalent to the information processing method. In addition, the program that realizes the actions of the production plan generating device 4, the supply equipment operation plan generating device 7, and the optimization device 8 is equivalent to the information processing program.

[0093] The production facility 1 is used for producing products. The production facility 1 receives power supply from the renewable energy supply facility 5 to produce products.

[0094] The production equipment 1 may include, for example, an injection molding machine or an extrusion molding machine for processing raw materials of the product. In addition, the production equipment 1 may also include processing devices such as a lathe and a grinder. In addition, the production equipment 1 may also include an assembly device for assembling the product by fastening parts such as screws and nuts to the product. In addition, the production equipment 1 may also include inspection devices such as a magnetic particle inspection device, a radioactive inspection device, and a penetration inspection device.

[0095] The production control device 2 controls the production equipment 1 according to the production plan of the product and manages the production of the product.

[0096] The production control device 2 is, for example, a programmable logic controller (PLC) or the like.

[0097] The public service facility 3 supplies resources required for production to the production facility 1 .

[0098] The resources supplied by the public service equipment 3 to the production equipment 1 are, for example, cold water, warm water, compressed air, or electricity.

[0099] In addition, the production equipment 1 and the public service equipment 3 are connected by a supply line for supplying resources such as a water supply pipe, an air pipe or an electric wire line, which is not shown in the figure. In addition, the public service equipment 3 is a device that cannot be controlled by the production control device 2. In addition, the managers who manage the production equipment 1 and the public service equipment 3 are sometimes different. In addition, the public service equipment 3 only supplies resources to the production equipment 1 controlled by the production control device 2. The public service equipment 3 does not supply resources to the production equipment 1 that is not controlled by the production control device 2.

[0100] The production plan generating device 4 generates a production plan for the production facility 1 .

[0101] Furthermore, the production plan generating device 4 generates a revised production plan when the optimization device 8 instructs the optimization device 8 to revise the production plan. Then, the production plan generating device 4 generates a new production plan based on the revised production plan.

[0102] The renewable energy supply facility 5 includes a renewable energy power generation device. The renewable energy supply facility 5 supplies the production facility 1 with electric power generated by the renewable energy power generation device.

[0103] The renewable energy supply device 5 is a power generation device whose power generation varies according to the state transition of the external environment. "The state transition of the external environment" means that the state of the environment in which the energy that will become the conversion source of electric energy is supplied to the power generation device changes with the passage of time. In the present embodiment, it is assumed that the renewable energy supply device 5 has a solar power generation device (PV) as a renewable energy power generation device. In the present embodiment, in an environment where light energy (solar energy) is irradiated as the conversion source of electric energy, the change in the irradiation amount of light energy (solar energy) over time is equivalent to the "external environment state transition". That is, in the present embodiment, the change in the amount of sunlight with the passage of time is equivalent to the "external environment state transition". As is well known, in a solar power generation device, the power generation varies according to the change in the amount of sunlight.

[0104] In addition, the renewable energy supply device 5 may also include other renewable energy power generation devices such as geothermal power generation devices and biomass power generation devices as solar power generation devices. Even if the renewable energy supply device 5 includes other renewable energy power generation devices such as geothermal power generation devices and biomass power generation devices, the renewable energy supply device 5 is equivalent to a power generation device whose power generation varies according to the state of the external environment.

[0105] Furthermore, the renewable energy supply facility 5 includes an electric shuttle vehicle (EV) for picking up employees and a power storage device.

[0106] In addition, as described above, due to the fluctuation of the power generation of the renewable energy supply device 5, the power generation may be insufficient for the power required by the production device 1 and the public service device 3. In this embodiment, in order to cope with the insufficient power generation, in addition to the renewable energy supply device 5, there is also Figure 1 Auxiliary power supply equipment not shown in the figure.

[0107] When the amount of power generated by the renewable energy supply facility 5 is insufficient, the renewable energy supply facility procures (purchases) the insufficient amount of power from the auxiliary power supply facility.

[0108] The supply equipment operation plan generating device 7 generates an operation plan for the renewable energy supply equipment 5 , that is, a supply equipment operation plan, based on the production plan generated by the production plan generating device 4 . The supply equipment operation plan is a power supply plan for the renewable energy supply equipment 5 .

[0109] Furthermore, when the optimization device 8 instructs the optimization device 8 to revise the production plan, the supply equipment operation plan generating device 7 generates a revised plan for the supply equipment operation plan based on the revised plan for the production plan generated by the production plan generating device 4 .

[0110] The supply control device 6 controls the renewable energy supply equipment 5 according to the supply equipment operation plan.

[0111] The supply control device 6 is, for example, a PLC or the like.

[0112] The optimization device 8 determines whether the production plan generated by the production plan generating device 4 needs to be corrected.

[0113] If it is determined that the production plan does not need to be corrected, the optimization device 8 approves the production plan. Then, the production equipment 1 is controlled based on the production plan approved by the optimization device 8. In addition, the renewable energy supply equipment 5 is controlled by the supply equipment operation plan based on the production plan approved by the optimization device 8.

[0114] On the other hand, when it is determined that the production plan needs to be corrected, the optimization device 8 instructs the production plan generating device 4 to generate a correction plan for the production plan. The production plan generating device 4 generates a plurality of correction plans for the production plan in accordance with the instruction from the optimization device 8.

[0115] The optimization device 8 selects an arbitrary correction plan from a plurality of correction plans of the production plan.

[0116] Then, the production facility 1 is controlled by the production plan according to the correction plan selected by the optimization device 8. Furthermore, the renewable energy supply facility 5 is controlled by the supply facility operation plan based on the correction plan selected by the optimization device 8.

[0117] The display device 9 generates a display screen reflecting 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 display screen on the monitor.

[0118] In addition, in this embodiment, an example in which the display device 9 is separated from the optimization device 8 is described, but the display device 9 may be integrated with the optimization device 8. That is, the optimization device 8 may also have a display function.

[0119] The network 10 connects the elements included in the production planning optimization system 100 .

[0120] Specifically, the network 10 connects the production equipment 1 with the production control device 2. In addition, the network 10 connects the production control device 2 with the production plan generating device 4. In addition, the network 10 connects the public service equipment 3 with the production plan generating device 4. In addition, the network 10 connects the production plan generating device 4 with the optimization device 8. In addition, the network 10 connects the optimization device 8 with the supply equipment operation plan generating device 7. In addition, the network 10 connects the optimization device 8 with the display device 9. In addition, the network 10 connects the supply equipment operation plan generating device 7 with the supply control device 6. In addition, the network 10 connects the supply control device 6 with the renewable energy supply equipment 5.

[0121] The network 10 is, for example, a field network such as CC-Link (Control & Communication Link, registered trademark). Alternatively, the network 10 may be a common network such as Ethernet (registered trademark) or a dedicated input / output line.

[0122] In addition, in the present embodiment, an example is described in which all the elements included in the production planning optimization system 100 are connected via the same network 10. However, they may be connected via different networks.

[0123] ***summary***

[0124] Here, in the description Figure 1 The details of the production plan generating device 4, the supply equipment operation plan generating device 7 and the optimization device 8 shown in FIG. Fig.44 and Fig.45 , an overview of the operations of the production plan generating device 4, the supply equipment operation plan generating device 7 and the optimizing device 8 is described.

[0125] First, the production plan generating device 4 generates a production plan (step S411). In the production plan, the production outline in the production facility 1 is defined.

[0126] Information indicating a production plan is referred to as production plan information. Fig.13 An example of production plan information is shown below. Fig.13 Details of the situation.

[0127] Next, the production plan generating device 4 generates a production equipment operation plan for each unit time based on the production plan (step S412 ).

[0128] The unit time is the time used to manage the production in the production equipment 1. The unit time is also called the calculation unit time. Fig.15 As shown, the unit time is, for example, 3600 seconds (= 1 hour).

[0129] The production equipment operation plan is an operation plan of the production equipment 1 and is a detailed production plan. In the production equipment operation plan, the product (model) to be produced, the production quantity, the operation to be performed by the production equipment 1, etc. are specified per unit time.

[0130] The information indicating the production equipment operation plan is referred to as production equipment operation plan information. Fig.21 An example of production equipment operation plan information is shown below. Fig.21 Details of the situation.

[0131] Furthermore, the production plan generating device 4 generates a public service equipment operation plan for each unit time based on the production equipment operation plan (step S413 ).

[0132] The public service equipment operation plan is an operation plan of the public service equipment 3. In the public service equipment operation plan, the supply amount of resources supplied from the public service equipment 3, the operation performed by the public service equipment 3, etc. are specified for each unit time.

[0133] The information showing the public service facility operation plan is referred to as public service facility operation plan information. Fig.24 An example of public service equipment operation plan information is shown. Fig.24 Details of the situation.

[0134] Furthermore, the production plan generating device 4 calculates the total amount of consumed resources consumed by the production facility 1 and the public service facility 3 based on the production facility operation plan and the public service facility operation plan (step S414 ).

[0135] Furthermore, the production plan generating device 4 calculates the total of the environmental load discharge amounts in the production facility 1 and the public service facility 3 based on the production facility operation plan and the public service facility operation plan (step S415 ).

[0136] Information showing the total of the consumed resources calculated by the production plan generating device 4 is referred to as consumed resource information. In addition, information showing the total of the environmental load discharge amount calculated by the production plan generating device 4 is referred to as environmental load information.

[0137] Fig.25 Examples of resource consumption information and environmental load information are shown below. Fig.25 Details of the situation.

[0138] Then, the production plan generating device 4 sends the production equipment operation plan information, the public service equipment operation plan information, the resource consumption information and the environmental load information to the optimizing device 8 (step S416).

[0139] The optimization device 8 receives production equipment operation plan information, public service equipment operation plan information, resource consumption information and environmental load information from the production plan generation device 4 (step S811).

[0140] Then, the optimization device 8 sends the production equipment operation plan information, the public service equipment operation plan information and the consumed resource information to the supply equipment operation plan generating device 7 (step S812).

[0141] The supply equipment operation plan generating device 7 receives the production equipment operation plan information, the public service equipment operation plan information and the consumed resource information from the optimizing device 8 (step S711).

[0142] Next, the supply equipment operation plan generating device 7 generates a PV power generation plan based on the weather forecast information (step S712 ). The PV power generation plan is a power generation plan of the solar power generation device (PV) included in the renewable energy supply equipment 5 .

[0143] Information indicating the PV power generation plan generated by the supply equipment operation plan generating device 7 is referred to as PV power generation plan information. Fig.31 An example of PV power generation plan information is shown below. Fig.31 Details of the situation.

[0144] Furthermore, the supply equipment operation plan generating means 7 generates an EV operation plan based on the production equipment operation plan information and the public service equipment operation plan information (step S713). The EV operation plan is an operation plan of EVs. EVs are used to transport employees working at the production equipment 1 and the public service equipment 3.

[0145] The information indicating the EV operation plan is referred to as EV operation plan information. Fig.32 An example of EV operation plan information is shown. Fig.32 Details of the situation.

[0146] Furthermore, the supply equipment operation plan generating device 7 generates a power storage plan, a discharge plan, and a purchase plan based on the consumption resource information, the PV power generation plan, and the EV operation plan (step S714).

[0147] The power storage plan is a plan related to storing the excess power in the storage battery and / or EV when the PV power generation exceeds the required power (the power required by the production facility 1 and the public service facility 3 ).

[0148] The discharge plan is a plan related to the discharge of the excess amount of stored electric power to the production equipment 1 .

[0149] The procurement plan is a plan related to procurement (purchase) of the shortfall in power from the auxiliary power supply equipment when the total power of the PV power generation amount and the power storage amount is short of the required power amount.

[0150] Furthermore, the supply equipment operation plan generating device 7 generates a supply equipment operation plan based on the resource consumption information, the PV power generation plan, the power storage plan, the discharge plan, and the purchase plan (step 715 ).

[0151] The information indicating the supply equipment operation plan is referred to as supply equipment operation plan information. Fig.35 An example of supply equipment operation plan information is shown.

[0152] In the supply equipment operation plan information, the demand side power consumption is based on the consumption resource information ( Fig.25 ). In addition, the PV power generation is based on the PV power generation plan. The battery charge and discharge amount and EV charge and discharge amount are based on the storage plan and discharge plan. The supply and demand power purchase amount is based on the procurement plan. Fig.35 Details of the situation.

[0153] Next, the supply equipment operation plan generating device 7 sends the supply equipment operation plan information to the optimizing device 8 (step S716).

[0154] The optimization device 8 receives the supply equipment operation plan information from the supply equipment operation plan generating device 7 (step S811).

[0155] Then, the optimization device 8 calculates the production cost based on the production equipment operation plan information, the public service equipment operation plan information, the consumed resource information, the environmental load information and the supply equipment operation plan information (step S813).

[0156] Production costs are costs required for production according to the production plan. In addition to labor costs and environmental load costs, production costs also include costs required to purchase electricity from auxiliary power supply equipment, namely power purchase costs (power purchase costs), etc.

[0157] Next, the optimization device 8 calculates the index value of the production cost, that is, the production evaluation index (step S814).

[0158] Next, the optimization device 8 determines whether correction of the production plan is required (step S815).

[0159] Specifically, the optimization device 8 determines whether the production evaluation index is consistent with the target value.

[0160] When the production evaluation index is consistent with the target value, the optimization device 8 determines that the production plan does not need to be corrected. When it is determined that the production equipment operation plan does not need to be corrected, the optimization device 8 approves the production plan generated by the production plan generation device 4 (step S816). When the optimization device 8 approves the production plan, the production equipment 1 is controlled by the production equipment operation plan generated by the production plan generation device 4. In addition, the renewable energy supply device 5 is controlled by the supply equipment operation plan generated by the supply equipment operation plan generation device 7.

[0161] On the other hand, when the production evaluation index does not agree with the target value, the optimization device 8 determines that correction of the production plan is necessary.

[0162] When it is determined that the production plan needs to be corrected, the optimization device 8 sends a correction plan generation instruction (step S817). The correction plan generation instruction is a command to instruct the production plan generation device 4 to generate a correction plan for the production plan.

[0163] The optimization device 8 enables the production plan generation device 4 to generate a correction plan for the production plan in an exhaustive manner so as to comply with the correction plan generation instructions.

[0164] In addition, the optimization device 8 may use the production cost instead of the production evaluation index in determining whether the production plan needs to be corrected. That is, the optimization device 8 may determine whether the production cost is consistent with the target value for the production cost. In this case, the optimization device 8 can omit the calculation of the production evaluation index (step 814).

[0165] like Fig.45 As shown, when receiving the correction plan generation instruction from the optimization device 8, the production plan generation device 4 generates a plurality of correction plans for the production plan by exhaustive method (step S420). Here, it is assumed that N (N≥2) correction plans are generated. Fig.65 An example of production plan correction plan information showing N correction plans for the production plan is shown. Fig.65 Details of the situation.

[0166] Thereafter, the processing of step S421 to step S825 is performed for each calibration plan. That is, the processing of step S421 to step S825 is repeated N times.

[0167] Specifically, the production plan generating device 4 generates an i-th new production plan based on the i-th (i is any one of 0 to N) correction plan (step S421 ).

[0168] Information indicating a new production plan is referred to as new production plan information.

[0169] The new production plan information is only numerical and Fig.13 The production plan information shown is different and in the same format as Fig.13 The production plan information shown is the same.

[0170] Furthermore, the production plan generating device 4 generates an i-th new production equipment operation plan based on the i-th new production plan (step S422 ).

[0171] Information indicating a new production equipment operation plan is referred to as new production equipment operation plan information.

[0172] The new production equipment operation plan information is only numerical and Fig.21 The production equipment operation plan information shown is different in format from Fig.21 The production equipment operation plan information shown is the same.

[0173] Furthermore, the production plan generating device 4 generates an i-th new public service equipment operation plan based on the i-th new production equipment operation plan (step S423 ).

[0174] The information indicating the new public service facility operation plan is referred to as new public service facility operation plan information.

[0175] The new production equipment operation plan information is only numerical and Fig.24 The public service equipment operation plan information shown is different and the format is the same as Fig.24 The public service equipment operation plan information shown is the same.

[0176] Furthermore, the production plan generating device 4 calculates the i-th new total of the consumed resources consumed by the production equipment 1 and the public service equipment 3 based on the i-th new production equipment operation plan and the i-th new public service equipment operation plan (step S424 ).

[0177] Information showing a new total of resources consumed by the production equipment 1 and the public service equipment 3 is referred to as new consumed resource information.

[0178] The new resource consumption information is only numerical and Fig.25 The resource consumption information shown is different and in the same format as Fig.25 The consumed resource information shown is the same.

[0179] Furthermore, the production plan generating device 4 calculates the i-th new total of the environmental load emissions in the production facility 1 and the public service facility 3 based on the i-th new production facility operation plan and the i-th new public service facility operation plan (step S425 ).

[0180] Information indicating a new total of the environmental load discharge amounts in the production facility 1 and the public service facility 3 is referred to as new environmental load information.

[0181] The new environmental load information is only numerical and Fig.25 The environmental load information shown is different and in the same format as Fig.25 The environmental load information shown is the same.

[0182] Then, the production plan generating device 4 sends the i-th new production equipment operation plan information, the i-th new public service equipment 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).

[0183] The optimization device 8 receives the i-th new production equipment operation plan information, the i-th new public service equipment operation plan information, the i-th new consumption resource information and the i-th new environmental load information from the production plan generation device 4 (step S821).

[0184] Then, the optimization device 8 sends the i-th new production equipment operation plan information, the i-th new public service equipment operation plan information and the i-th new consumption resource information to the supply equipment operation plan generation device 7 (step S822).

[0185] The supply equipment operation plan generating device 7 receives the i-th new production equipment operation plan information, the i-th new public service equipment operation plan information and the i-th new consumption resource information from the optimizing device 8 (step S721).

[0186] Next, the supply equipment operation plan generating device 7 generates the i-th new PV power generation plan based on the weather forecast information (step S722). In addition, step S722 may be omitted. In this case, the supply equipment operation plan generating device 7 uses the previously generated PV power generation plan in step S724 described later.

[0187] Furthermore, the supply equipment operation plan generating device 7 generates an i-th new EV operation plan based on the i-th new production equipment operation plan information and the i-th new public service equipment operation plan information (step S723 ).

[0188] Furthermore, the supply equipment operation plan generating device 7 generates an i-th new storage plan, an i-th new discharge plan, and an i-th new purchase 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).

[0189] In addition, the supply equipment operation plan generating device 7 generates the i-th new supply equipment operation plan based on the i-th new resource consumption information, the i-th new PV power generation plan, the i-th new power storage plan, the i-th new discharge plan and the i-th new procurement plan (step 725).

[0190] The information indicating the new supply equipment operation plan is referred to as new supply equipment operation plan information.

[0191] The new supply equipment operation plan information is only numerical and Fig.35 The supply equipment operation plan information shown is different in format from Fig.35 The supply equipment operation plan information shown is the same.

[0192] Next, the supply equipment operation plan generating device 7 sends the i-th new supply equipment operation plan information to the optimizing device 8 (step S726).

[0193] The optimization device 8 receives the i-th new supply equipment operation plan information from the supply equipment operation plan generating device 7 (step S821).

[0194] Then, the optimization device 8 calculates the i-th new production cost based on the i-th new production equipment operation plan information, the i-th new public service equipment operation plan information, the i-th new resource consumption information, the i-th new environmental load information and the i-th new supply equipment operation plan information (step S823).

[0195] Next, the optimization device 8 calculates the i-th new production evaluation index which is the index value of the i-th new production cost (step S824).

[0196] Next, the optimization device 8 determines whether all correction plans of the production plan have been tried (step S825). That is, the optimization device 8 determines whether the production evaluation index has been calculated for all N correction plans.

[0197] When all the calibration cases have not been tried, the processing from step S421 onwards is repeated for the (i+1)th calibration case.

[0198] On the other hand, when all correction plans have been tried, the optimization device 8 selects the correction plan for the production plan with the smallest production evaluation index (step S826).

[0199] Thereafter, the production facility 1 is controlled by a new production plan corresponding to the correction plan selected by the optimization device 8. Furthermore, the renewable energy supply facility 5 is controlled by a new supply facility operation plan corresponding to the new production plan.

[0200] In addition, the optimization device 8 may also use production costs instead of production evaluation indicators in the selection of correction plans. That is, the optimization device 8 may also select a correction plan for the production plan with the minimum production costs. In this case, the optimization device 8 can omit the calculation of the production evaluation indicators (step 824).

[0201] Thus, in the present embodiment, when the optimization device 8 determines that the production plan needs to be corrected, the production plan generation device 4 generates a correction plan for the production plan. Then, the supply equipment operation plan generation device 7 uses the production plan based on the generated correction plan and the PV power generation plan generated based on the weather forecast to generate a new power storage plan, a new discharge plan, and a new procurement plan. In addition, the supply equipment operation plan generation device 7 reflects the new power storage plan, the new discharge plan, and the new procurement plan to generate a new supply equipment operation plan. In addition, the optimization device 8 uses the new supply equipment operation plan to calculate the production evaluation index, and selects an arbitrary correction plan from a plurality of correction plans based on the production evaluation index. In addition, the optimization device 8 selecting an arbitrary correction plan from a plurality of correction plans is synonymous with the optimization device 8 determining whether to correct the production plan according to each correction plan.

[0202] Here, an example is described in which the optimization device 8 selects a correction plan with the smallest production evaluation index from a plurality of correction plans generated by exhaustive enumeration.

[0203] Alternatively, the production plan generation device 4 may generate one correction plan at a time, and the optimization device 8 may determine whether the production evaluation index based on the correction plan is consistent with the target value each time the production plan generation device 4 generates the correction plan. That is, the optimization device 8 may also perform step S815 after step S824 to determine whether the new production evaluation index is consistent with the target value. In this case, the optimization device 8 selects the corresponding correction plan when the new production evaluation index is consistent with the target value. On the other hand, when the new production evaluation index is inconsistent with the target value, the optimization device 8 performs step S817 to instruct the production plan generation device 4 to generate a further correction plan for the production plan.

[0204] In the exhaustive method, it is not possible to select the correction plan to be reflected in the production plan until all the correction plans are generated and the production evaluation indexes for all the correction plans are calculated. On the other hand, in this method, the correction plan to be reflected in the production plan can be selected in advance.

[0205] **Details of the production plan generating device 4**

[0206] Next, the production plan generating device 4 will be described in detail.

[0207] Figure 2 A hardware configuration example of the production plan generating device 4 according to the first embodiment is shown.

[0208] like Figure 2As shown, the production plan generating device 4 includes a control unit 41, a storage 42, a memory 43, a communication unit 44, and an input unit 45. The production plan generating device 4 also includes a power source (not shown) serving as a power source.

[0209] The control unit 41 controls the production plan generating device 4 .

[0210] The control unit 41 may also be a processor such as a CPU (Central Processing Unit). In addition, the control unit 41 may also be an integrated circuit such as an FPGA (Field Programmable Gate Array), an LSI (Large Scale Integration), or an ASIC (Application Specific Integrated Circuit). In addition, the control unit 41 may also be a combination of a processor and an integrated circuit.

[0211] In addition, the control unit 41, which is a higher-level concept of a processor and an integrated circuit, can also be replaced by a "processing circuit".

[0212] In this embodiment, an example in which the control unit 41 is a processor that executes a program will be described. That is, the control unit 41 executes the production plan generation program 421 stored in the memory 42. The details of the production plan generation program 421 will be described later.

[0213] The control unit 41 controls the storage 42 , the memory 43 , the communication unit 44 , and the input unit 45 , executes the production plan generation program 421 , and generates a production plan.

[0214] The memory 42 stores various programs executed by the control unit 41 , data referred to when the control unit 41 executes the various programs, data generated as a result of the control unit 41 executing the programs, and the like.

[0215] The storage 42 stores, for example, a production plan creation program 421 .

[0216] The storage 42 is, for example, a non-volatile memory such as a flash memory, a ROM (Read Only Memory), a hard disk, a solid state drive, or a memory card reader.

[0217] The memory 43 is a storage device that is directly accessed when the control unit 41 executes the processing of the program. Various programs and data stored in the storage 42 are copied to the memory 43 and temporarily stored.

[0218] The memory 43 is, for example, a volatile memory such as a RAM (Random Access Memory).

[0219] Furthermore, the control unit 41 usually temporarily stores the program stored in the storage 42 in the memory 43 , and executes the program by reading the program from the memory 43 .

[0220] The communication unit 44 includes a receiver for receiving data and a transmitter for transmitting data.

[0221] The communication unit 44 communicates with an external device using a receiver and a transmitter.

[0222] The input unit 45 receives input from the user and is, for example, a keyboard, a mouse, a touch pad, or a touch panel having a display function.

[0223] Next, a functional configuration example of the production plan generating device 4 according to the present embodiment will be described.

[0224] Figure 3 A functional configuration example of the production plan generating device 4 is shown.

[0225] exist Figure 3 In the example, the information input unit 451 uses the input unit 45 to input production plan requirement information based on the order data from the user of the production plan generating device 4 .

[0226] The order data shows the order contents (order) from the customer. More specifically, the order data specifies which product (model) is to be produced, when (production delivery date), in which batches (production batch number), and how many (production quantity).

[0227] The production plan required information defines information required for generating a production plan reflecting the order indicated by the order data.

[0228] When it is necessary to generate a correction plan for the production plan, the information input unit 451 receives input of production start time interval information from a user of the production plan generating device 4 using the input unit 45. Details of the production start time interval information will be described later.

[0229] Here, the information required for production planning is explained.

[0230] The production plan requires information, including information on the model, production delivery date, production batch number, and production quantity specified by the order data. In addition, the production plan requires information, including information on the earliest possible production time, production start time, and available production lines. The earliest possible production time refers to the earliest time when the production of the product specified by the order data can be started within the period until the production delivery date. The production start time refers to the time when the production of the product starts. A possible production line is a production line that can produce a product. For example, when product X can be produced by both production line Y and production line Z, the available production lines for product X are production line Y and production line Z.

[0231] The parameters to be changed in the instruction unit 815 described later (hereinafter, changed parameters) are the following three.

[0232] The first is the production quantity of each model on each production line.

[0233] The second is the production order. When the production of two or more models is planned within the delivery period in the same production line, the designation unit 815 can change the production order between the models.

[0234] Then, the third is the production start time. When the production completion time (total production time) of all models scheduled for production is earlier than the delivery date, the designation unit 815 can change the production start time.

[0235] In this embodiment, these three parameters are treated as discrete values. Alternatively, the production quantity and production start time may be treated as continuous values.

[0236] The control unit 41 executes Figure 2 The production plan generation program 421 is shown.

[0237] Figure 3 The following schematically shows a state in which the control unit 41 executes the production plan generating program 421 .

[0238] The production plan generation program 421 includes programs for realizing the functions of the production plan generation unit 411 , the production equipment operation plan generation unit 412 , the communication control unit 413 , the public service equipment operation plan generation unit 414 , and the resource load calculation unit 415 .

[0239] In the following, for the sake of simplicity, the situation in which the control unit 41 executes the program to implement the respective functions of the production plan generation unit 411, the production equipment operation plan generation unit 412, the communication control unit 413, the public service equipment operation plan generation unit 414, and the resource load calculation unit 415 will be explained as the actions of the production plan generation unit 411, the production equipment operation plan generation unit 412, the communication control unit 413, the public service equipment operation plan generation unit 414, and the resource load calculation unit 415.

[0240] In addition, the production plan generation unit 411, the production equipment operation plan generation unit 412, the communication control unit 413, the public service equipment operation plan generation unit 414, and the resource load calculation unit 415 executed by the control unit 41 are equivalent to the "correction unit". In addition, the processing performed by the production plan generation unit 411, the production equipment operation plan generation unit 412, the communication control unit 413, the public service equipment operation plan generation unit 414, and the resource load calculation unit 415 is equivalent to the "correction processing".

[0241] The production plan generation unit 411 performs Fig.44 Step S411 and Fig.45 Step S420 and step S421.

[0242] Specifically, the production plan generating unit 411 generates a production plan based on the production plan requirement information and the production equipment information.

[0243] The production equipment information is pre-stored in the main database 431. The details of the production equipment information will be described later.

[0244] The production plan generation unit 411 acquires the production equipment information from the master database 431. Then, the production plan generation unit 411 generates a production plan based on the order data acquired from the information input unit 451 and the production equipment information acquired from the master database 431.

[0245] The production plan generation unit 411 outputs the production plan information indicating the production plan to the production equipment operation plan generation unit 412. In addition, the production plan generation unit 411 stores the production plan information in the master database 431. As described above, the production plan information is Fig.13 The information illustrated.

[0246] In addition, when the production plan generation unit 411 receives a correction plan generation instruction from the optimization device 8 via the communication control unit 413, it generates a plurality of correction plans for the production plan in an exhaustive manner based on the correction plan generation instruction. In the correction plan generation instruction, the change parameters reflected in the correction plan are indicated. The production plan generation unit 411 generates a correction plan based on the change parameters indicated in the correction plan generation instruction. For example, in the correction plan generation instruction, "production quantity" is indicated as a change parameter reflected in the correction plan. When "production quantity" is indicated in the correction plan generation instruction, the production plan generation unit 411 generates a plurality of correction plans for changing the production quantity of any product.

[0247] The production plan generation unit 411 sets a calibration case number i for each calibration case. Here, the production plan generation unit 411 generates N calibration cases. In this case, the calibration case number i takes any one of 0 to N. Hereinafter, the i-th calibration case, the i-th production plan information, the i-th production equipment information, etc. may be used for expression. The calibration case number i is set for the i-th calibration case, the i-th production plan information, and the i-th production equipment information, respectively.

[0248] The production plan generation unit 411 generates the i-th production plan for each correction plan by referring to the production plan requirement information and the production equipment information. The production plan generation unit 411 outputs the i-th production plan information indicating the i-th production plan to the production equipment operation plan generation unit 412. In addition, the production plan generation unit 411 stores the i-th new production plan information in the master database 431.

[0249] The production equipment operation plan generation unit 412 performs Fig.44 Step S412 and Fig.45 Step S422.

[0250] Specifically, the production equipment operation plan generation unit 412 generates the i-th production equipment operation plan for each unit time based on the i-th production plan information and the production equipment information generated by the production plan generation unit 411 .

[0251] The production equipment operation plan generating unit 412 outputs the i-th production equipment operation plan information indicating the i-th production equipment operation plan to the public service equipment operation plan generating unit 414. In addition, the production equipment operation plan generating unit 412 stores the i-th production equipment operation plan information in the production equipment operation plan database 432. As described above, the production equipment operation plan information is Fig.21 The information illustrated.

[0252] Furthermore, when the i-th production plan information is generated by the production plan generating unit 411 , the production equipment operation plan generating unit 412 generates the i-th production equipment operation plan based on the i-th production plan information and the i-th production equipment information.

[0253] The production equipment operation plan generation unit 412 outputs the i-th production equipment operation plan information indicating the i-th production equipment operation plan to the common service equipment operation plan generation unit 414. The production equipment operation plan generation unit 412 also stores the i-th production equipment operation plan information in the production equipment operation plan database 432.

[0254] The public service equipment operation plan generation unit 414 performs Fig.44 Step S413 and Fig.45 Step S423.

[0255] Specifically, the public service equipment operation plan generator 414 generates the i-th public service equipment operation plan for each unit time based on the i-th production equipment operation plan information and the public service equipment information. The public service equipment operation plan is an operation plan for the public service equipment 3 .

[0256] The public service equipment information is pre-stored in the main database 431. The details of the public service equipment information will be described later.

[0257] The public service equipment operation plan generator 414 obtains the public service equipment information from the master database 431 , and then generates the i-th public service equipment operation plan based on the i-th production equipment operation plan information obtained from the production equipment operation plan generator 412 and the public service equipment information obtained from the master database 431 .

[0258] The public service equipment operation plan generation unit 414 outputs the i-th production equipment operation plan information and the i-th public service equipment operation plan information showing the i-th public service equipment operation plan to the resource load calculation unit 415. In addition, the public service equipment operation plan generation unit 414 stores the i-th public service equipment operation plan information in the public service equipment operation plan database 433. As described above, the public service equipment operation plan information is Fig.24 The information illustrated.

[0259] Furthermore, when the i-th production equipment operation plan information is generated by the production equipment operation plan generating unit 412 , the public service equipment operation plan generating unit 414 generates the i-th public service equipment operation plan based on the i-th production equipment operation plan information and the public service equipment information.

[0260] The public service equipment operation plan generation unit 414 outputs the i-th production equipment operation plan information and the i-th public service equipment operation plan information showing the i-th public service equipment operation plan to the resource load calculation unit 415. In addition, the production equipment operation plan generation unit 412 stores the i-th public service equipment operation plan information in the public service equipment operation plan database 433.

[0261] The resource load calculation unit 415 performs Fig.44 Step S415 and step S416 and Fig.45 Step S425 and step S426.

[0262] Specifically, the resource load calculation unit 415 calculates the total of resources consumed by the production equipment 1 and the public service equipment 3 based on the i-th production equipment operation plan information and the i-th public service equipment operation plan information. Then, the resource load calculation unit 415 stores the i-th consumed resource information showing the calculated total of resources in the resource load database 434.

[0263] Furthermore, the resource load calculation unit 415 calculates the total of the environmental load emission amounts in the production equipment 1 and the public service equipment 3 based on the i-th production equipment operation plan information and the i-th public service equipment operation plan information. Then, the resource load calculation unit 415 stores the i-th environmental load information showing the total of the environmental load emission amounts in the resource load database 434.

[0264] As mentioned above, resource consumption information and environmental load information are Fig.25 The information illustrated.

[0265] In addition, when the public service equipment operation plan generating unit 414 generates the i-th public service equipment operation plan information, the resource load calculating unit 415 generates the i-th resource consumption information and the i-th environmental load information based on the i-th production equipment operation plan information and the i-th public service equipment operation plan information. Then, the resource load calculating unit 415 stores the i-th resource consumption information and the i-th environmental load information in the resource load database 434.

[0266] The communication control unit 413 uses the communication unit 44 to communicate with the production control device 2, the public service equipment 3 and the optimization device 8.

[0267] Specifically, the communication control unit 413 reads the production equipment operation plan information from the production equipment operation plan database 432 via the production equipment operation plan generation unit 412. Then, the communication control unit 413 transmits the read production equipment operation plan information to the production control device 2 and the optimization device 8.

[0268] Furthermore, the communication control unit 413 reads out the public service equipment operation plan information from the public service equipment operation plan database 433 via the public service equipment operation plan generation unit 414. Then, the communication control unit 413 transmits the read out public service equipment operation plan information to the public service equipment 3 and the optimization device 8.

[0269] Furthermore, the communication control unit 413 reads out the consumed 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 consumed resource information and environmental load information to the optimization device 8.

[0270] In addition, the communication control unit 413 receives a correction plan generation instruction from the optimization device 8.

[0271] When receiving a correction plan generation instruction from the optimization device 8 , the communication control unit 413 outputs the correction plan generation instruction to the production plan generation unit 411 .

[0272] In addition, when receiving a correction plan generation instruction from the optimization device 8, the communication control unit 413 sends the i-th production equipment operation plan information, the i-th public service equipment operation plan information, the i-th consumption resource information and the i-th environmental load information to the optimization device 8.

[0273] **Details of the supply equipment operation plan generating device 7**

[0274] Next, the supply equipment operation plan generating device 7 will be described in detail.

[0279] In addition, the control unit 71, which is a higher-level concept of a processor and an integrated circuit, can also be renamed as a "processing circuit."

[0280] In this embodiment, an example is described in which the control unit 71 is a processor that executes a program.

[0348] Furthermore, the communication control unit 811, the production cost calculation unit 812, the production evaluation index calculation unit 813, and the instruction unit 815 executed by the control unit 81 are equivalent to the "correction unit". Furthermore, the processing performed by the communication control unit 811, the production cost calculation unit 812, the production evaluation index calculation unit 813, and the instruction unit 815 is equivalent to the "correction processing".

[0349] Production cost calculation unit 812 performs Fig.44 Step S813.

[0350] Specifically, the production cost calculation unit 812 calculates the production cost based on the production equipment operation plan information, the public service equipment operation plan information, the consumption resource information, the environmental load information, and the supply equipment operation plan information.

[0351] The production cost calculation unit 812 calculates the production cost for each cost item such as the power purchase cost, labor cost, and environmental load cost.

[0352] The production cost calculation unit 812 outputs production cost information indicating the production cost for each cost item to the production evaluation index calculation unit 813 .

[0353] Furthermore, the production cost calculation unit 812 stores the production cost information in the production cost database 832. Furthermore, the production cost calculation unit 812 stores the production equipment operation plan information, the public service equipment operation plan information, the consumption resource information, the environmental load information and the supply equipment operation plan information in the main database 831.

[0354] The production evaluation index calculation unit 813 performs Fig.44 Step S814.

[0355] Specifically, the production evaluation index calculation unit 813 calculates a production evaluation index which is an index value of production cost.

[0356] The production evaluation index calculation unit 813 obtains the weight coefficient from the weight coefficient input unit 851. Then, the production evaluation index calculation unit 813 multiplies the amount of the cost by the corresponding weight coefficient according to each cost item of the production cost. Then, the production evaluation index calculation unit 813 adds up the multiplied values ​​of each cost item to obtain the production evaluation index.

[0363] The determination unit 814 outputs the production evaluation index information and determination result information indicating the determination result to the instruction unit 815 .

[0364] The instruction unit 815 performs Fig.44 Step S816 or step S817.

[0365] Specifically, the instructing unit 815 determines that the production plan does not need to be corrected if the determination unit 814 determines that the production evaluation index matches the target value. If the production plan is not needed, the instructing unit 815 approves the production plan generated by the production plan generating device 4.

[0366] When the production plan is approved, the instruction unit 815 reads the production equipment operation plan information from the master database 831. Then, the instruction unit 815 outputs the read production equipment operation plan information to the communication control unit 811.

[0367] On the other hand, when the production evaluation index does not coincide with the target value, the instruction unit 815 determines that correction of the production plan is necessary.

[0368] Then, when it is determined that the production plan needs to be corrected, the instruction unit 815 outputs a correction plan generation instruction to the communication control unit 811 to cause the production plan generation device 4 to generate a correction plan for the production plan.

[0369] The correction plan generation instruction includes the change parameters to be reflected in the correction plan.

[0374] Furthermore, the communication control unit 811 transmits the correction plan generation instruction from the instruction unit 815 to the production plan generation device 4 .

[0375] Furthermore, the communication control unit 811 receives the i-th production equipment operation plan information, the i-th public service equipment operation plan information, the i-th resource consumption information, and the i-th environmental load information from the production plan generating device 4 .

[0376] The communication control unit 811 outputs the received i-th production equipment operation plan information, i-th public service equipment operation plan information, i-th resource consumption information, and i-th environmental load information to the production cost calculation unit 812 .

[0377] In addition, the communication control unit 811 sends the i-th production equipment operation plan information, the i-th public service equipment operation plan information, and the i-th consumption resource information to the supply equipment operation plan generating device 7 .

The communication control unit 811 outputs the received i-th supply equipment operation plan information to the production cost calculating unit 812.

[0379] When the communication control unit 811 receives the i-th production equipment operation plan information, the i-th public service equipment operation plan information, the i-th consumed resource information, and the i-th environmental load information, the production cost calculation unit 812 calculates the i-th production cost based on the i-th production equipment operation plan information, the i-th public service equipment operation plan information, the i-th consumed resource information, and the i-th environmental load information.

[0380] Then, the production cost calculation unit 812 outputs the i-th production cost information indicating the i-th production cost to the production evaluation index calculation unit 813 .

[0381] In addition, the production cost calculation unit 812 stores the i-th production cost information in the production cost database 832.

[0383] Then, the production evaluation index calculation unit 813 calculates the i-th production evaluation index which is the index value of the i-th production cost.

[0384] Furthermore, the production evaluation index calculation unit 813 outputs the i-th production evaluation index information indicating the i-th production evaluation index to the instruction unit 815 .

[0385] Furthermore, the production evaluation index calculation unit 813 stores the i-th production evaluation index information in the production evaluation index database 833 .

[0386] Furthermore, when the instruction unit 815 obtains the i-th production evaluation index information from the production evaluation index calculation unit 813 , it stores the obtained i-th production evaluation index information in the production plan change database 835 .

[0387] In addition, the instruction unit 815 determines whether all the correction plans of the production plan have been tried each time the i-th production evaluation index information is obtained. That is, the instruction unit 815 determines whether N new production evaluation index information for N correction plans has been obtained. Specifically, the instruction unit 815 determines whether the value i as the correction plan number is consistent with N. In addition, it is assumed that the instruction unit 815 is notified separately from the production plan generation unit 411 that the total number of correction plans is N.

[0388] When all the calibration plans have not been tried, the instruction unit 815 waits for acquisition of new production evaluation index information for the next calibration plan.

[0389] On the other hand, when all the correction plans have been tried, the instruction unit 815 selects the production evaluation index information indicating the minimum production evaluation index.

[0390] Then, the instruction unit 815 reads out the production equipment operation plan information in which the same correction plan number as the selected production evaluation index information is set from the main database 831. Then, the instruction unit 815 outputs the read production equipment operation plan information to the communication control unit 811.

[0391] The communication control unit 811 transmits the production equipment operation plan information obtained from the instruction unit 815 to the display device 9 .

[0461] The production equipment operation plan generation unit 412 generates a production plan based on the production plan information ( Fig.13 ) and production equipment information ( Figure 8 to Figure 12 , Figures 14 to 20 ),generate Fig.21 The production equipment operation plan information shown in the example.

[0462] Specifically, the production equipment operation plan generation unit 412 Figure 8 Each production process shown in the process information is based on Fig.12 Device action information, Fig.10 productive information, Fig.11 Process action information and Fig.13 Production planning information is generated Fig.21 Production equipment operation plan information.

[0463] Here, the production equipment operation plan generation unit 412 is described as follows: Figure 8 The "Processing 1" generates Fig.21 An example of production equipment operation plan information.

[0464] In addition, in this embodiment, the time spent on the transportation of products between production processes is included in the production processing time of each production process. In addition, the transportation of products between production processes is implemented every 1 hour. Furthermore, the products produced in each production process are transported to the next production process.

[0465] The production equipment operation plan generation unit 412 Fig.11 The process action information obtains "start", "processing 1 processing", "standby", "end processing" and "stop" as the equipment actions of "processing 1".

[0466] For "Processing 1", the production equipment operation plan generation unit 412 Fig.12 The device action information obtains "1 hour" as the start action time, obtains "1 hour" as the end processing action time, and obtains "0 hours" as the stop action time.

[0467] In addition, for "Processing 1", the production equipment operation plan generation unit 412 Fig.10 The productivity information obtains "Product A" as the product and "14.4 seconds / piece" as the production capacity.

[0468] In addition, for "machine type A" and "processing 1", the production equipment operation plan generation unit 412 Fig.13 The production plan information obtains "2021 / 04 / 05 09:00" as the production start time and "6000 pieces" as the production quantity.

[0469] Moreover, for "Processing 1", "1 hour" is required as the start-up action time, and the production start time is "2021 / 04 / 05 09:00", so the production equipment operation plan generation unit 412 decides that the start of "Processing 1" will start at "2021 / 04 / 05 08:00". In addition, the production quantity of "Product A" is "6000 pieces", and the production capacity of "Product A" is "14.4 seconds / piece", so the production equipment operation plan generation unit 412 determines that "Processing 1" of "Processing 1" requires 24 hours (6000 pieces × 14.4 seconds ÷ 3600 seconds = 24 hours). Therefore, the production equipment operation plan generation unit 412 determines that 250 pieces (6000 pieces ÷ 24 hours = 250 pieces) of processing are performed in 1 hour. Furthermore, the production equipment operation plan generation unit 412 determines that "Processing 1" is completed from "2021 / 04 / 05 09:00" to "2021 / 04 / 06 9:00" 24 hours later. Fig.21 The "Processing 1 Production Quantity" from "2021 / 04 / 05 09:00" to "2021 / 04 / 05 08:00" is "250 pieces".

[0470] The production equipment operation plan generation unit 412 determines that the “end process” of “processing 1” starts at “2021 / 04 / 06 09:00”.

[0471] Furthermore, for “Processing 1”, “1 hour” is required as the operation time for the end processing, and therefore, the production equipment operation plan generation unit 412 determines to perform “Stop” of “Processing 1” at “2021 / 04 / 06 10:00”.

[0472] The production equipment operation plan generating unit 412 performs the same processing on “processing 2”, “processing 3”, and “processing 4”.

[0615] Fig.39 An example of the worker headcount information is shown.

[0616] like Fig.39 As shown, the operator number information consists of the production process and the number of operators.

[0617] In the item of production process, each production process of process 1 to process 4 is shown.

[0618] The item of the number of workers shows the number of workers required in each production process.

[0619] The information on the number of operators is stored in the main database 831.

[0620] Fig.40 An example of CO2 emission unit price information is shown.

[0621] like Fig.40 As shown, the CO2 emission unit price information consists of electricity-CO2 conversion and CO2 emission unit price.

[0622] The item of electricity-CO2 conversion shows a value for converting the amount of power consumption into the amount of CO2 emissions.

[0623] The item of CO2 emission unit price shows the cost per 1 kg of CO2.

[0624] The CO2 emission unit price information is stored in the main database 831 .

[0625] Fig.41 An example of production cost information is shown.

[0626] like Fig.41 As shown, the production cost information consists of object, electricity, air, labor cost, CO2, and total.

[0627] exist Fig.41In the example of , the production cost of the entire supply and demand is shown. The production cost of the entire supply and demand refers to the total cost incurred by the production equipment 1, the public service equipment 3 and the supply equipment operation plan generation device 7.

[0628] The item of electricity shows the cost of electricity consumed in the production facility 1 , the public service facility 3 , and the supply facility operation plan generating device 7 .

[0629] The item of air shows the cost of air consumed in the production facility 1 , the public service facility 3 , and the supply facility operation plan generating device 7 .

[0630] The labor cost item shows the cost of labor consumed in the production facility 1 , the public service facility 3 , and the supply facility operation plan generating device 7 .

[0631] The item of CO 2 shows the cost of environmental load consumed in the production facility 1 , the public service facility 3 , and the supply facility operation plan generating device 7 .

[0632] The total items show the totals of the values ​​of electricity, air, labor costs, and CO2.

[0633] The production cost calculation unit 812 calculates the power purchase cost information based on the supply and demand ( Fig.37 ) and get the value of "electricity".

[0634] The production cost calculation unit 812 calculates the labor cost based on the labor cost information ( Fig.38 )、Number of operators information( Fig.39 ) to get the value of “labor fee”.

[0635] The production cost calculation unit 812 calculates the environmental load information based on the environmental load information ( Fig.25 )、Supply and demand electricity purchase cost information( Fig.37 )、CO2 emission unit price information( Fig.40 ) to get the value of "CO2".

[0636] The production evaluation index calculation unit 813 calculates the production cost information based on the production cost information ( Fig.41 ), calculate the production evaluation index.

[0637] Specifically, the production evaluation index calculation unit 813 calculates the production evaluation index through the following process.

[0638] In the present embodiment, the production evaluation index is classified into productivity, energy efficiency, and environmental load.

[0639] The production evaluation index of productivity is obtained by multiplying the labor cost of each production process by the load time and dividing the multiplied value by the production quantity (Formula 6).

[0640] The production evaluation index of energy efficiency is obtained by multiplying the power consumption cost of each production process by the load time and dividing the multiplied value by the load time (Formula 7).

[0641] The production evaluation index of the environmental load is obtained by the sum of the values ​​obtained by dividing the environmental load cost of each production process by the load time (Formula 8).

[0642] Here, the load time is obtained by subtracting the planned downtime time from the working time of the factory based on the current production plan as shown in Formula 9.

[0643] In addition, here, only labor costs are used when calculating the productive production evaluation index. In addition to labor costs, consumable resources other than power consumption, such as material costs, may also be used when calculating the productive production evaluation index. In addition, production evaluation indicators of consumable resources other than power consumption, such as material costs, may also be calculated.

[0644] Formula 6: (Productivity) = Σ(Labor Cost) × (Load Time) / (Production Quantity)

[0645] Formula 7: (Energy efficiency) = Σ(power consumption cost) × (load time) / (production quantity)

[0646] Formula 8: (Environmental load) = Σ(Environmental load cost) × (Load time) / (Production quantity)

[0647] Formula 9: (Load time) = (Operation time) - (Planned rest time)

[0648] Furthermore, the production evaluation index calculation unit 813 generates a final production evaluation index according to the production evaluation indexes of energy efficiency, productivity, and environmental load according to Formula 10. In addition, the more appropriate the production plan is, the smaller the value of the production evaluation index obtained by Formula 10 is.

[0649] Formula 10: (Production evaluation index) = w1×(Productivity) + w2×(Energy efficiency) + w3×(Environmental load)

[0650] w1, w2, w3: weight coefficients (set by user) (w1+w2+w3=1)

[0651] The weight coefficients w1, w2, and w3 can be appropriately set by the user according to the environment of the production site, the priority of evaluation, the digital alignment of each item, etc. In addition, when all the weight coefficients are added together, 1 is obtained.

[0652] Fig.42 An example of the production evaluation index information generated by the production evaluation index calculation unit 813 is shown.

[0653] like Fig.42 As shown, the production evaluation index information is composed of object, productivity, energy efficiency, environmental load, and total.

[0654] In addition, Fig.42 In the example of , the production evaluation index calculated by w1=0.1, w2=0.05, and w3=0.85 is shown.

[0655] The determination unit 814 obtains the target value information from the target value database 834 .

[0656] Fig.43 An example of target value information is shown.

[0657] The target value information shows the target value of the production evaluation index.

[0658] The determination unit 814 compares the value of the "target value" with the production evaluation index.

[0659] The determination unit 814 determines the production evaluation index information ( Fig.42 )’s production evaluation index (total) is compared with the target value information to determine whether the production plan needs to be corrected.

[0660] If the production evaluation index information ( Fig.42 ) is below the target value, the determination unit 814 determines that the production plan does not need to be corrected. On the other hand, if the production evaluation index information ( Fig.42 ) is greater than the target value, the determination unit 814 determines that the production plan needs to be corrected.

[0661] In addition, the target value can be arbitrarily set by the user of the optimization device 8.

[0662] When the determination unit 814 determines that the production plan needs to be corrected, the instruction unit 815 instructs the production plan generating device 4 to generate a correction plan of the production plan by the exhaustive method as described above.

[0663] Fig.65 An example of the production plan correction plan information generated by the production plan generating unit 411 is shown.

[0664] like Fig.65 As shown in the figure, the production plan correction plan information consists of the correction plan number, production process, target machine model, production start time, production delivery date and production quantity. Fig.65 In FIG. 1 , for simplicity, a correction plan for the production plan is shown that targets only the model B and the model D manufactured by process 2.

[0665] In the item of the calibration plan number, a number corresponding to the number of calibration plans generated by the production plan generation unit 411 is shown. Fig.65 It shows that N correction cases are generated).

[0666] In the item of the target model, the model of the target of calibration is shown.

[0667] In the production process item, the production process of the object of correction is shown. In the production process item, Figure 8 The arbitrary production process shown in the production process item.

[0668] The item of production start time shows a correction plan of the production start time. That is, the item of production start time shows a correction plan of the time when the production process shown in the item of production process starts.

[0669] The item of production end time shows a correction plan of the production end time. That is, the item of production end time shows a correction plan of the time when the production process shown in the item of production process ends.

[0670] The item of production quantity shows a correction plan of the production quantity. That is, the item of production quantity shows a correction plan of the production quantity of the model shown in the item of target model.

[0671] The production plan generation unit 411 generates a calibration plan according to the change parameter specified by the calibration plan generation instruction. In the calibration plan generation instruction, at least one of "production quantity", "production sequence" and "production start time" is specified as the change parameter.

[0672] Here, in the calibration plan generation instruction, "production quantity", "production sequence" and "production start time" are designated as change parameters.

[0673] Since the "production quantity" is designated as the change parameter, the production plan creation unit 411 creates a correction plan for changing the production quantities of model B and model D.

[0674] Furthermore, since the “production sequence” is designated as the change parameter, the production plan creation unit 411 creates a correction plan for changing the production sequence of the model B and the model D.

[0675] Furthermore, since the “production start time” is designated as the change parameter, the production plan creation unit 411 creates a correction plan for changing the production start time of the model B and the model D.

[0676] exist Fig.13 In the production plan of the production plan information, it is planned to produce 800 units of model B through process 2. In addition, it is planned to produce 290 units of model D through process 2.

[0677] The production plan generation unit 411 generates a correction plan to change the original plan of producing 800 units of model B and 290 units of model D in process 2. That is, the production plan generation unit 411 changes the production number of model B within the range of 0 to 799 units, and changes the production number of model D within the range of 0 to 279 units. Then, the production plan generation unit 411 generates N correction plans that cover all combinations of the production number of model B and the production number of model D in process 2.

[0678] exist Fig.65 In the calibration case number: 1, the production quantity of model B and model D is 0. In the calibration case number: K, the production quantity of model B and model D is 50. In the calibration case number: N, the production quantity of model B is 799 and the production quantity of model D is 289.

[0679] In addition, Fig.13 In the production plan of the production plan information, it is planned to produce model D after producing model B in process 2.

[0680] The production plan generation unit 411 generates a correction plan to change the original plan of producing model D after producing model B. That is, the production plan generation unit 411 generates a correction plan in which model D is produced first and model B is produced later.

[0681] exist Fig.65 The calibration plan number: K shows that the model D is produced first and the model B is produced after the production of the model D is completed.

[0682] In addition, Fig.13 In the production plan of the production plan information, the production start time of process 2 is "2021 / 04 / 05 09:00".

[0683] The production plan generation unit 411 generates a correction plan to change the original plan of starting the processing 2 at "2021 / 04 / 05 09:00". That is, the production plan generation unit 411 generates a correction plan to start the processing 2 at a different time.

[0684] exist Fig.65 In the correction case number: N, it is shown that the correction case for processing 2 started at "2021 / 04 / 05 03:00".

[0685] When generating a correction plan for changing the production start time, the production plan generating unit 411 first calculates the width by which the production start time of the process 2 can be changed (production start time changeable width).

[0686] The start time of the variable width at the production start time is the earliest time that production can be produced. The end time of the variable width at the production start time is the time obtained by subtracting the production time from the production delivery time. For example, if the delivery date 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, then "2021 / 04 / 05 12:30", which is obtained by subtracting 20 hours from "2021 / 04 / 06 08:30" which is the delivery date, is the end time of the variable width at the production start time.

[0687] Next, the production plan generation unit 411 refers to the production start time interval information. The production start time interval information shows the unit for changing the production start time by the production plan generation unit 411. Specifically, the production start time interval information shows time units such as "1 hour" and "30 minutes".

[0688] Here, for the sake of simplicity, it is assumed that the changeable width of the production start time of process 2 is "2021 / 04 / 05 03:00" to "2021 / 04 / 05 09:00". In this case, when "1 hour" is indicated in the production start time interval information, the production plan generation unit 411 generates a correction plan for the production start time of process 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 indicated in the production start time interval information, the production plan generation unit 411 generates a correction plan for the production start time of processing 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".

[0689] The production plan generating unit 411 generates a calibration plan in such a manner as to include all combinations of change parameters designated in the calibration plan generating instruction.

[0690] Then, the production plan generating unit 411 generates a new production plan for each correction plan.

[0691] Here, for the sake of simplicity, it is assumed that model B and model D can be produced in all processing steps (processing 1, processing 3, and processing 3) except processing 2. That is, the production line of model B and model D includes processing 1, processing 3, and processing 3.

[0692] For example, in Fig.65 In the correction case number: 1, the number of model B and model D produced by process 2 is 0. Therefore, the production plan generation unit 411 generates a new production plan to produce 800 model B and 290 model D in process 1, process 3, and process 3 in total. Fig.65 In the correction plan number: K of , the number of model B and model D produced by process 2 is 50. Therefore, the production plan generation unit 411 generates a new production plan to produce 750 model B and 240 model D in the total of process 1, process 3, and process 4.

[0693] Then, as described above, after trying all the correction plans, the instruction unit 815 selects the production plan that obtains the minimum production evaluation index.

[0694] ***Comparison between the sequential method and the synchronous method***

[0695] Next, the optimization method of the production plan of the technology of Patent Document 1 and the optimization method of the production plan of the present embodiment are compared.

[0696] Hereinafter, the production plan optimization method of the technology of Patent Document 1 is referred to as a sequential method. In addition, the production plan optimization method of the present embodiment is referred to as a synchronous method.

[0697] Fig.46 An example of production plan information optimized in a sequential manner is shown. Fig.46 Corresponds to Fig.13 .

[0698] In the sequential method, when making a production plan, all production processes are performed during the night time period when the electricity price is low, within the range that does not incur overtime labor costs. Therefore, in the sequential method, a production plan can be made that suppresses overtime costs and has low electricity costs.

[0699] However, in the sequential method, the power supply of the renewable energy supply equipment is not taken into consideration when the production plan is prepared.

[0700] Fig.47 An example of production plan information optimized by synchronization is shown. Fig.47 Corresponds to Fig.13 .

[0725] Right now, Fig.59 Corresponds to Fig.41 .

[0726] Fig.60 Show according to Fig.46 The example of production evaluation index information generated based on the production plan information of the sequential method is shown.

[0727] Right now, Fig.60 Corresponds to Fig.42 .

[0728] Fig.61 Show according to Fig.47 The example of production evaluation index information generated based on the production plan information of the synchronous method is shown.

[0729] Right now, Fig.61 Corresponds to Fig.42 .

[0730] In the sequential method, all processing steps are performed in the time period with low electricity prices, regardless of the amount of electricity supplied by the renewable energy supply equipment 5, and production is suppressed in the time period with high electricity prices. Fig.52 As shown, the demand-side power consumption is low during the daytime hours and high during the nighttime hours.

[0731] On the other hand, Fig.54 As shown, the PV power generation of the renewable energy supply device 5 is more in the daytime period. Therefore, there is a time period during the day when the demand-side power consumption is lower than the PV power generation. Specifically, from "2021 / 4 / 5 14:00" to "2021 / 4 / 5 15:00", the demand-side power consumption is lower than the PV power generation.

[0732] During these time periods, the excess of PV power generation over the demand-side power consumption is stored in the storage battery. Fig.54 In the example of , the stored electricity is supplied to the demand side at "2021 / 4 / 5 20:00" and "2021 / 4 / 5 21:00".

[0733] like Fig.29 As shown, the charging and discharging efficiency of the storage battery is 90%, and therefore the amount of electric power that can be supplied when the storage battery is stored and then discharged is 81% of the amount of generated power, which is not efficient.

[0734] As a result, in the successive method, the cost of purchasing electricity will increase, e.g. Fig.56 As shown, a total of 15,602 yen of supply and demand electricity purchase costs were generated.

[0735] On the other hand, in the synchronous method, the production plan is optimized while taking into account the power supply of the renewable energy supply equipment 5. Therefore, in the synchronous method, all processing steps are performed in the time period when the power supply of the renewable energy supply equipment 5 is large.

[0736] like Fig.53 As shown, in the synchronous mode, the demand-side power consumption amount is high during the daytime period and low during the nighttime period.

[0737] As described above, the PV power generation of the renewable energy supply device 5 is characterized by the fact that more power is generated during the daytime. Fig.55 As shown, during the day, the demand-side power consumption exceeds the PV power generation.

[0738] Therefore, in the synchronous mode, electricity is not stored in the storage battery, and the charging and discharging efficiency of the storage battery is not affected. Therefore, in the synchronous mode, the renewable energy supply equipment 5 can efficiently supply electric power.

[0739] As a result, in the synchronous mode, the power purchase cost of the supply and demand can be suppressed. Specifically, in the synchronous mode, if Fig.57 As shown, the total supply and demand electricity purchase cost can be suppressed to 14,625 yen.

[0740] In the synchronous mode, the power purchase cost can be reduced by about 6% compared with the sequential mode.

[0741] In addition, the synchronous method can reduce the cost related to CO2 emissions by about 15% compared to the sequential method.

[0742] Here, the synchronous method and the sequential method are compared by the cost of purchasing electricity according to supply and demand and the cost related to CO2 emissions, but the same comparison can be made even for environmental load substances such as Volatile Organic Compounds (VOC) gases.

[0743] according to Fig.60 and Fig.61 Among the production evaluation indicators, the synchronous method obtains better values ​​in both energy efficiency and environmental load than the sequential method.

[0744] **Description of the effects of the implementation method**

[0745] In this embodiment, a storage plan, a discharge plan, and a purchase plan are generated based on the production plan correction plan and the power generation plan predicted based on the state transition of the external environment. Then, the production plan correction plan to be adopted is selected based on the generated storage plan, discharge plan, and purchase plan.

[0746] Therefore, according to this embodiment, even when a power generation facility whose power generation varies according to changes in the state of the external environment is used as a power supply source, a production plan with a storage plan, a discharge plan, and a purchase plan that can efficiently utilize the changes in the power generation can be selected.

[0747] In addition, in the method of this embodiment, the correction plan with the smallest production cost or the index value obtained from the production cost is selected from a plurality of correction plans. Therefore, according to this embodiment, the production cost can be suppressed.

[0748] Furthermore, according to the present embodiment, it is possible to generate a production plan that complies with environmental laws and regulations such as carbon dioxide emissions, VOC gas emissions, and power usage restrictions without reducing production efficiency.

[0749] Implementation method 2.

[0750] In the first embodiment, an example in which a correction plan for a production plan is generated by an exhaustive method has been described.

[0751] In this embodiment, an example of suppressing the number of generated correction plans for a production plan will be described.

[0752] In this embodiment, the differences from Embodiment 1 are mainly described.

[0753] In addition, matters not described below are the same as those in Implementation 1.

[0754] ***Structure description***

[0755] Fig.62 A functional configuration example of the optimization device 8 according to the present embodiment is shown.

[0756] exist Fig.62 In, with Figure 7 In comparison, a learning model generation unit 817 and a learning model database 837 are added.

[0757] Elements other than the learning model generation unit 817 and the learning model database 837 Figure 7 The elements shown are the same.

[0758] The learning model generation unit 817 is included in the optimization program 821 in the same manner as the instruction unit 815 and the like.

[0759] The learning model generation unit 817 learns the production plan corrected in the past and generates a learning model reflecting the learning result.

[0760] The learning model generation unit 817 stores the generated learning model in the learning model database 837 .

[0761] In this embodiment, production plan correction log information is stored for production plans corrected in the past in the production plan change database 835. The production plan correction log information includes pre-correction production plan information, post-correction production plan information, pre-correction order data, and post-correction order data.

[0762] The pre-correction production plan information is production plan information indicating a production plan before correction is performed (pre-correction production plan).

[0763] The corrected production plan information is production plan information indicating a production plan corrected according to the correction plan selected by the instruction unit 815 (corrected production plan).

[0764] The pre-correction order data is order data used to generate the pre-correction production plan.

[0765] The corrected order data is order data used to generate the corrected production plan.

[0766] The learning model generation unit 817 obtains the production plan correction log information from the production plan change database 835. Then, the learning model generation unit 817 uses the obtained production plan correction log information to perform machine learning such as reinforcement learning to generate a learning model. The learning model generation unit 817 learns the relationship between the difference between the order data before correction and the order data after correction and the difference between the production plan information before correction and the production plan information after correction. That is, the learning model generation unit 817 learns how the production plan changes when which parameter of the order data is changed in which way.

[0767] The learning model is a model that serves as a guideline for correcting the production plan.

[0768] In addition, the learning model generation unit 817 may periodically update the learning model. In addition, the learning model database 837 is periodically copied to the storage 82.

[0769] In the present embodiment, before the learning model generation unit 817 generates the learning model, the instruction unit 815 causes the production plan generation device 4 to generate a correction plan of the production plan by exhaustive enumeration, similar to the first embodiment.

[0770] Each time the instruction unit 815 selects a correction plan to be adopted for the production plan, it stores the pre-correction production plan information, the post-correction production plan information, the pre-correction order data, and the post-correction order data in the production plan change database 835 as production plan correction log information.

[0771] After the learning model generation unit 817 generates the learning model, the instruction unit 815 generates a new production plan as a revised production plan using the learning model. Then, the instruction unit 815 transmits new production plan information indicating the new production plan to the production plan generation device 4 via the communication control unit 811 .

[0772] The production plan generating device 4 generates a new production equipment operation plan based on the new production plan.

[0773] ***Action description***

[0774] Fig.63 and Fig.64 An operation example of the production plan generating device 4, the supply equipment operation plan generating device 7, and the optimizing device 8 according to the present embodiment is shown.

[0775] Fig.63 Corresponds to Fig.44 . Fig.64Corresponds to Fig.45 .

[0776] exist Fig.63 In the process of the production plan generating device 4, steps S411 to S416 are as follows: Fig.44 In addition, steps S711 to S716 as the operation of the supply equipment operation plan generating device 7 are also the same as Fig.44 same.

[0777] In addition, in the operation of the optimization device 8, steps S811 to S816 are also Fig.44 same.

[0778] In this 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 generating device 4.

[0779] exist Fig.64 In, with Fig.45 That is, the production plan generation unit 411 does not generate a correction plan and a new generation plan, and in step S422, the production equipment operation plan generation unit 412 generates a new production equipment operation plan based on the new generation plan information sent from the optimization device 8.

In addition, the instruction unit 815 stores the production plan correction log information in the production plan change database 835.

[0784] On the other hand, when the production evaluation index is inconsistent with the target value and the production plan needs to be corrected, in step S847, the instruction unit 815 uses the learning model to further generate a new production plan.

Alternatively, the instruction unit 815 may also generate a new production plan using a solution search method based on a genetic algorithm, Lagrangian relaxation method, etc. In this way, the instruction unit 815 can generate production plan information with the minimum production evaluation index within a limited time.
