Mode for Carrying Out the Invention

[0012] (Summary of the Present Disclosure) The restoration equipment notification method according to one aspect of the present disclosure includes, when two or more of a plurality of facilities each performing a first step are stopped, estimating the productivity of one or more post-process facilities that use at least one of the members produced by each of the two or more facilities among the one or more post-process facilities that perform a second step, which is a subsequent step of the first step; identifying, based on the productivity of the one or more post-process facilities, one of the two or more facilities as a target facility for restoration work; and notifying the identified target facility.

[0013] Thereby, since the productivity of the post-process facility is utilized, the productivity of the post-process facility can be efficiently increased by restoring the identified target facility. Therefore, according to the restoration equipment notification method according to this aspect, improvement in productivity can be supported.

[0014] Further, for example, in the identifying step, based on the productivity of the one or more post-process facilities, a priority of each of the two or more facilities may be set, and a facility whose set priority is higher than a threshold value may be identified as the target facility.

[0015] Thereby, since the priority is set based on the productivity of the post-process facility, the productivity of the post-process facility can be efficiently increased when the target facility identified based on the priority is restored.

[0016] Further, for example, in the identifying step, based on the productivity of the one or more post-process facilities, a priority of each of the two or more facilities may be set, the priorities may be compared, and a facility whose set priority is higher than the others may be identified as the target facility.

[0017] As a result, since the priority is set based on the productivity of the post-process equipment, when the target equipment specified based on the priority is restored, the productivity of the post-process equipment can be efficiently increased.

[0018] Also, for example, in the estimating step, when a first equipment among the plurality of equipment is stopped, when a second equipment different from the first equipment among the plurality of equipment is stopped, the number of first members that the first equipment produces, which is the number required in the second process during a predetermined period, and the number of second members that the second equipment produces, which is the number required in the second process during the predetermined period, are estimated as the productivity of the one or more post-process equipment, and in the specifying step, the number of first members and the number of second members are compared, and (a) when the number of first members is larger than the number of second members, the priority of the first equipment is set higher than the priority of the second equipment, and (b) when the number of second members is larger than the number of first members, the priority of the second equipment may be set higher than the priority of the first equipment.

[0019] The number of members required by the post-process equipment is one of the indicators directly representing the productivity of the post-process equipment. By setting the priority based on this number of members, it is possible to appropriately identify the target equipment that contributes to the improvement of productivity.

[0020] Also, for example, in the estimating step, the productivity of each of the two or more equipment is further estimated, and in the specifying step, the priority of each of the two or more equipment is set based on the productivity of each of the two or more equipment.

[0021] As a result, since the productivity of the equipment in the first process (described as the current process equipment) is further utilized, it is possible to identify the target equipment suitable for improving the productivity of the entire production system including the current process equipment and the post-process equipment.

[0022] Also, for example, in the estimating step, when a first facility among the plurality of facilities has stopped, when a second facility different from the first facility among the plurality of facilities has stopped, the number of first members produced by the first facility is the number of first members required in the second process during a predetermined period, and the number of second members produced by the second facility is the number of second members required in the second process during the predetermined period, are estimated as the productivity of the one or more post-process facilities, and the first increase amount which is the number by which the first members increase when the first facility is restored, and the second increase amount which is the number by which the second members increase when the second facility is restored, may be estimated as the production quantity of each of the two or more facilities. In the specifying step, (a) when the number of first members is greater than the number of second members and the first increase amount is greater than the second increase amount, the priority of the first facility is set higher than the priority of the second facility, (b) when the number of second members is greater than the number of first members and the second increase amount is greater than the first increase amount, the priority of the second facility may be set higher than the priority of the first facility.

[0023] The number of members required by the post-process facility is one of the indicators directly representing the productivity of the post-process facility. The increase amount due to the production in the current process facility is one of the indicators directly representing the productivity of the current process facility. By setting the priority based on these numbers of members and increase amounts, it is possible to appropriately identify the target facilities contributing to the improvement of productivity.

[0024] Further, for example, the restoration facility notification method according to one aspect of the present disclosure may include a step of acquiring weight information indicating the weight of each of the first step and the second step. In the specifying step, the weight of the second step is multiplied by each of the first member number and the second member number, the weight of the first step is multiplied by each of the first increment and the second increment, and a first evaluation value which is a sum value of the first member number after the weight is multiplied and the first increment after the weight is multiplied, and a second evaluation value which is a sum value of the second member number after the weight is multiplied and the second increment after the weight is multiplied are calculated, and (a) when the first evaluation value is greater than the second evaluation value, the priority of the first facility is set higher than the priority of the second facility, and (b) when the second evaluation value is greater than the first evaluation value, the priority of the second facility may be set higher than the priority of the first facility.

[0025] Thereby, by using the weights of the current process and the subsequent process, it is possible to prioritize the processes that are likely to contribute to the improvement of productivity. Thereby, it is possible to support the improvement of the productivity of the entire production system.

[0026] Further, for example, the restoration facility notification method according to one aspect of the present disclosure may include a step of acquiring weight information indicating the weight of each of the first step and the second step. In the specifying step, (i) when the weight of the second step is greater than the weight of the first step, (a) when the number of the first members is greater than the number of the second members and the first increase amount is less than the second increase amount, the priority of the first facility is set higher than the priority of the second facility, (b) when the number of the second members is greater than the number of the first members and the second increase amount is less than the first increase amount, the priority of the second facility is set higher than the priority of the first facility, (ii) when the weight of the first step is greater than the weight of the second step, (a) when the number of the first members is greater than the number of the second members and the first increase amount is less than the second increase amount, the priority of the second facility is set higher than the priority of the first facility, (b) when the number of the second members is greater than the number of the first members and the second increase amount is less than the first increase amount, the priority of the first facility may be set higher than the priority of the second facility.

[0027] Thereby, by using the weights of the current process and the subsequent process, it is possible to prioritize the process that is likely to contribute to the improvement of productivity. Thereby, it is possible to support the improvement of the productivity of the entire production system.

[0028] Further, for example, in the estimating step, the first usage number, which is the number of the first members used in the second step during the predetermined period, and the second usage number, which is the number of the second members used in the second step during the predetermined period, are estimated, the first unused number, which is the number of the first members not yet used in the second step, and the second unused number, which is the number of the second members not yet used in the second step, are acquired, a value obtained by subtracting the first unused number from the first usage number is calculated as the number of the first members, and a value obtained by subtracting the second unused number from the second usage number may be calculated as the number of the second members.

[0029] By using the unused quantity of the produced members in this way, the number of members required in the subsequent process equipment can be calculated as a more realistic value. For this reason, since the priority set based on the number of members is set more appropriately, the target equipment that contributes to the improvement of productivity can be specified appropriately.

[0030] Also, for example, in the step of estimating, when there are a plurality of subsequent process equipment that use the first member, for each of the plurality of subsequent process equipment, the number of the first members used during the predetermined period is estimated, and the value obtained by summing up the estimated numbers is calculated as the first usage quantity. When there are a plurality of subsequent process equipment that use the second member, for each of the plurality of subsequent process equipment, the number of the second members used during the predetermined period is estimated, and the value obtained by summing up the estimated numbers may be calculated as the second usage quantity.

[0031] Thereby, when the members produced by the current process equipment are used in a plurality of subsequent process equipment, the required number of members can be calculated as a more realistic value. For this reason, since the priority set based on the number of members is set more appropriately, the target equipment that contributes to the improvement of productivity can be specified appropriately.

[0032] Also, for example, in the step of estimating, when the subsequent process equipment that uses the first member satisfies a predetermined condition, the number of the first members used in the subsequent process equipment is set to 0. When the subsequent process equipment that uses the second member satisfies a predetermined condition, the number of the second members used in the subsequent process equipment may be set to 0.

[0033] Thereby, for example, when a predetermined condition such as the subsequent process equipment being stopped plannedly or being under maintenance is satisfied, the number of members used in the subsequent process equipment becomes 0. By omitting the processing required for estimating the number of members, the amount of calculation can be reduced.

[0034] Further, for example, the restoration facility notification method according to one aspect of the present disclosure includes the steps of obtaining equipment information including the operation and stop status of each of the plurality of facilities, the operation and stop status of each of the one or more subsequent process facilities, and the stop factors of the one or more subsequent process facilities, member type information including the type of member produced by each of the plurality of facilities, and correspondence information indicating, for each type of member, the subsequent process facilities that use the members produced by each of the plurality of facilities in the second process. In the step of estimating, the productivity of the one or more subsequent process facilities may be estimated by inputting the first equipment information, the second equipment information, the factor information, the member type information, and the correspondence information into a learning model created by machine learning.

[0035] Thereby, by using machine learning, the estimation accuracy of productivity can be improved. As the operation time of the production system becomes longer and the data used for machine learning increases, the estimation accuracy also improves, so that it becomes possible to identify the optimal target facilities contributing to the improvement of productivity.

[0036] Further, for example, in the step of notifying, a notification image in which two or more equipment identification information representing each of the two or more facilities is arranged in descending order of the priority of the corresponding facility may be displayed.

[0037] Thereby, since the equipment identification information is arranged in descending order of priority, the operator can easily grasp the target equipment. Since the operator can promptly start the restoration work, further improvement of productivity can be supported.

[0038] Further, for example, in the step of notifying, the notification image may be updated each time an increase or decrease in the two or more facilities occurs.

[0039] Thereby, each time an increase or decrease in the stopped equipment occurs, such as a new stop of the equipment or the start of operation of the equipment due to the completion of the restoration work, the notification image is updated. Therefore, since the appropriate target equipment is notified according to the change in the situation, it has excellent real-time performance and can support further improvement of productivity.

[0040] Also, for example, in the estimating step, when a first facility among the plurality of facilities is stopped, when a second facility different from the first facility among the plurality of facilities is stopped, the number of first members that are the number of members produced by the first facility and required in the second process during a predetermined period, and the number of second members that are the number of members produced by the second facility and required in the second process during the predetermined period are estimated as the productivity of the one or more subsequent process facilities. In the specifying step, the number of first members and the number of second members are compared, and (i) when the number of first members is greater than the number of second members, the first facility is specified as the target facility, and (ii) when the number of second members is greater than the number of first members, the second facility may be specified as the target facility.

[0041] Thereby, the number of members required in the subsequent process facilities is one of the indices directly representing the productivity of the subsequent process facilities. Based on the magnitude relationship of this number of members, it is possible to appropriately specify the target facility that contributes to the improvement of productivity.

[0042] Further, a restoration facility notification device according to an aspect of the present disclosure includes an estimation unit that estimates the productivity of one or more subsequent process facilities that utilize at least one of the members produced by each of two or more facilities among a plurality of facilities each performing a first process, when the two or more facilities are stopped; a specifying unit that specifies, based on the productivity of the one or more subsequent process facilities, one of the two or more facilities as a target facility for restoration work; and a notification unit that notifies the specified target facility.

[0043] Thereby, since the productivity of the subsequent process facilities is utilized, when the specified target facility is restored, the productivity of the subsequent process facilities can be efficiently increased. Therefore, according to the restoration facility notification device according to this aspect, it is possible to support the improvement of productivity.

[0044] Further, a restoration equipment notification system according to an aspect of the present disclosure includes the restoration equipment notification device according to the above aspect and a terminal device that outputs information for an operator of a restoration operation to identify the target equipment.

[0045] As a result, since the productivity of the post-process equipment is utilized, if the identified target equipment is restored, the productivity of the post-process equipment can be efficiently increased. Therefore, according to the restoration equipment notification system according to this aspect, it is possible to support the improvement of productivity.

[0046] Hereinafter, embodiments will be specifically described with reference to the drawings.

[0047] Note that each of the embodiments described below shows comprehensive or specific examples. The numerical values, shapes, materials, components, arrangement positions and connection forms of the components, steps, order of steps, etc. shown in the following embodiments are merely examples and are not intended to limit the present disclosure. In addition, among the components in the following embodiments, the components not described in the independent claims are described as optional components.

[0048] Also, each figure is a schematic diagram and is not necessarily drawn precisely. Therefore, for example, the scales in each figure do not necessarily match. In each figure, substantially the same configuration is denoted by the same reference numeral, and overlapping descriptions are omitted or simplified.

[0049] (Embodiment 1) [1-1. An example of a factory to which the restoration equipment notification system is applied] First, an example of a factory to which the restoration equipment notification system according to the embodiment is applied will be described with reference to FIG. 1. FIG. 1 is a plan view showing the configuration of a factory 1 to which the restoration equipment notification system according to the present embodiment is applied.

[0050] As shown in FIG. 1, in factory 1, a plurality of manufacturing facilities 100 are arranged. Each of the plurality of manufacturing facilities 100 performs one of a plurality of processes for manufacturing a product. The manufacturing facility 100 is, for example, a member mounting machine, a processing device, an assembly device, etc., but is not particularly limited. The manufacturing facility 100 produces a member by executing a process and outputs the produced member.

[0051] The member is, for example, a component included in the final product (i.e., the product), or a work-in-progress during the manufacture of the final product, but is not limited thereto. The member is an object used to produce a component or a work-in-progress and may not be included in the final product. Note that the manufacturing facility 100 may be any facility related to the manufacture of a product, and may also be an inspection device that inspects members, work-in-progress, or products.

[0052] In this specification, "production" not only means making a final product, but also includes processing, assembling, inspecting, etc. of members (components or work-in-progress). For example, the member produced by the manufacturing facility 100 is the member output after the manufacturing facility 100 executes the assigned process (processing, assembling, inspecting, etc.). Also, "manufacture" is an example of production, and when the final product is an industrial product, "manufacture" is used in the same meaning as "production".

[0053] In factory 1, a plurality of workers 2A to 2D are engaged. In the example shown in FIG. 1, the inside of factory 1 is divided into four blocks A to D, and workers are assigned to each block. For example, worker 2A performs recovery work on the 10 manufacturing facilities 100 arranged in block A. In the following, an explanation regarding worker 2A will be given, but the same applies to workers 2B to 2D.

[0054] When the manufacturing equipment 100 stops, the operator 2A performs the recovery work on the stopped manufacturing equipment 100. At this time, as shown in FIG. 1, it is possible that a plurality of manufacturing equipment 100a to 100c stop simultaneously. For example, when the manufacturing equipment 100a stops, the operator 2A performs the recovery work on the manufacturing equipment 100a, but before the recovery work on the manufacturing equipment 100a is completed, it is possible that the manufacturing equipment 100b and 100c stop. When a plurality of manufacturing equipment 100 stops, by recovering the stopped manufacturing equipment 100 in an appropriate order, the productivity of the entire factory 1 can be increased.

[0055] Hereinafter, the relationship between the manufacturing equipment 100 and the points that may cause problems when identifying the target equipment for the recovery work will be described with reference to FIG. 2.

[0056] FIG. 2 is a diagram showing the relationship between the current process equipment and the subsequent process equipment.

[0057] The current process equipment is equipment that executes the current process. The current process is an example of the first process and is a process performed by the equipment that is the notification target of the recovery equipment notification system according to the present embodiment. In other words, when two or more of the plurality of equipment that execute the first process stop, the recovery equipment notification system according to the present embodiment identifies and notifies one of the two or more equipment as the target equipment. For example, the ten manufacturing equipment 100 belonging to block A shown in FIG. 1 correspond to the current process equipment. In FIG. 2, six pieces of equipment A to F are shown.

[0058] As shown in FIG. 2, the members produced by each of the plurality of current process equipment are temporarily stored in the member storage area before being used in the subsequent process equipment. The member storage area may be a part of the transfer device that transfers the members from the current process equipment to the subsequent process equipment. In the present embodiment, a member storage area is provided for each current process equipment. For example, the member a produced by the equipment A is stored in the member storage area of the equipment A.

[0059] The post-process equipment is the equipment that executes the post-process. The post-process is an example of the second process and is the process immediately after the first process. The post-process equipment executes the second process using one or more members produced by the current-process equipment. For example, ten manufacturing equipments 100 belonging to block B shown in FIG. 1 correspond to the post-process equipment. In FIG. 2, four equipments W to Z are shown.

[0060] In the example shown in FIG. 2, equipment X uses member a produced by equipment A and member b produced by equipment B. Equipment Y uses member c produced by equipment C and member d produced by equipment D. Equipment Z uses member c produced by equipment C and member d produced by equipment D. Equipment W uses member e produced by equipment E and member f produced by equipment F.

[0061] FIG. 2 shows the situation at a certain point in time in the operating factory. Specifically, the current-process equipments A, C, and F are operating, but the current-process equipments B, D, and E are stopped. In the respective member storage areas corresponding to each of equipments A to E, six members a, four members b, three members c, one member d, and one member e are stored. In the member storage area of equipment F, no member f produced by equipment F is stored. The post-process equipment X is in a long-term planned stop. The post-process equipments Y and Z are operating. The post-process equipment W has stopped waiting for the supply of member f because there is no member f to use.

[0062] In such a situation, when one operator performs recovery work on the currently stopped equipments B, D, and E, it is important which equipment among equipments B, D, and E is to be recovered. For example, when determining the equipment to be the target of the recovery work in consideration of the productivity of the current-process equipment, if the productivity of equipment B is the highest, equipment B is determined as the recovery work. However, even if equipment B is recovered, since the post-process equipment X is in a planned stop, the member b produced by equipment B is not used by equipment X. Therefore, as long as equipment X does not operate, the productivity will not improve even if equipment B is recovered. Thus, even considering the productivity of the current-process equipment, it does not necessarily lead to an improvement in productivity.

[0063] On the other hand, in the restoration equipment notification system according to the present embodiment, the productivity of the post-process equipment is estimated, and the target equipment is specified and notified based on the estimated productivity. Thereby, improvement of productivity can be supported.

[0064] For example, as described above, since the equipment X in the post-process is in planned stop, even if the equipment B that produces the member b used by the equipment X is restored, it will not lead to an improvement in productivity. Therefore, the priority of the equipment B is lowered. Also, the equipment W has stopped waiting for members, but the missing member is the member f. The equipment F that produces the member f is in operation. Since the member e used by the equipment W is stored in the member storage area, even if the equipment E is restored, it does not necessarily lead to an improvement in productivity.

[0065] On the other hand, the equipment Y and Z are each in operation, and the members c and d used by each are stored in the member storage area. However, since only one member d is arranged in the member storage area, it will soon be used up. When the supply of the member d stops, both the equipment Y and Z will stop due to waiting for members, and the productivity will decrease. Therefore, when the equipment D is restored to produce the member d, it is possible to avoid the stop of the equipment Y and Z due to waiting for members and improve the productivity. Therefore, the equipment D can be determined as the target equipment for the restoration work.

[0066] As described above, according to the restoration equipment notification system according to the present embodiment, by estimating the productivity of the post-process equipment and specifying and notifying the target equipment based on the estimated productivity, improvement of productivity can be supported.

[0067] [1-2. Restoration Equipment Notification System] Hereinafter, the specific configuration of the restoration equipment notification system according to the present embodiment will be described with reference to FIGS. 3 to 6.

[0068] FIG. 3 is a block diagram showing the configuration of the restoration equipment notification system 10 according to the present embodiment. As shown in FIG. 3, the restoration equipment notification system 10 includes a plurality of manufacturing facilities 100, a restoration equipment notification device 200, and a terminal device 300. The plurality of manufacturing facilities 100, the restoration equipment notification device 200, and the terminal device 300 are communicably connected to each other via a network 400. The communication of each device may be wired communication or wireless communication. Further, the terminal device 300 may also serve as the restoration equipment notification device 200. Further, the terminal device 300 may be provided for each worker.

[0069] [1-2-1. Manufacturing Facility] First, the configuration of the manufacturing facility 100 will be described with reference to FIG. 4. FIG. 4 is a block diagram showing the configuration of the manufacturing facility 100 according to the present embodiment.

[0070] As shown in FIG. 4, the manufacturing facility 100 includes a storage unit 111, a processing unit 112, a communication unit 113, an input unit 114, a display unit 115, a material input unit 121, a transport unit 122, a manufacturing unit 123, a product output unit 124, an operation time specifying unit 131, a stop time specifying unit 132, and a stop cause specifying unit 141. Each component of the manufacturing facility 100 is communicably connected to each other.

[0071] The storage unit 111 is a memory for storing equipment information, data, programs, etc. related to the manufacturing facility 100. For example, the storage unit 111 stores the equipment name (e.g., identification number) of the manufacturing facility 100 and the types of parts to be produced. The storage unit 111 may store a production plan and operation results (operation time, stop time, stop cause, etc.). The storage unit 111 is realized by a non-volatile storage device such as an HDD (Hard Disk Drive) or a semiconductor memory.

[0072] The processing unit 112 performs processing for controlling the overall operation of the manufacturing facility 100. The processing unit 112 is realized by, for example, a processor. The processing unit 112 generates instructions for controlling each component of the manufacturing facility 100 and outputs them to each component. Further, the processing unit 112 generates operation results (manufacturing log information) such as the content of the processing performed by each component and the occurrence time of events, and stores them in the storage unit 111.

[0073] The communication unit 113 is a communication interface for the manufacturing facility 100 to communicate with other devices. The communication unit 113 communicates with, for example, the recovery facility notification device 200, and transmits to the recovery facility notification device 200 the facility name, the type of member to be produced, the stop time, the stop cause, the operation time, and the like.

[0074] The input unit 114 receives operation inputs from workers for the manufacturing facility 100. The input unit 114 is realized by, for example, physical operation buttons, but may also be a touch panel display and / or a voice input device, etc. For example, when the input unit 114 receives an input from a worker, the processing unit 112 may regard the time as the arrival time of the worker. The arrival time of the worker can be regarded as the time when the recovery work starts (the start time of work).

[0075] The display unit 115 is a display for displaying the operation state of the manufacturing facility 100 and the like. The display unit 115 is realized by a liquid crystal display or an organic EL (Electroluminescence) display device, etc.

[0076] The material input unit 121 is a device for inputting materials used in the manufacture of products. The materials are not particularly limited, for example, resin or metal materials before molding, resin parts or metal parts after molding, or substrates, circuit components, etc. The materials are gases, liquids, solids, powders, granular materials, etc. When the manufacturing facility 100 is a post-process facility, the material input unit 121 inputs the members produced by the current process facility as materials.

[0077] The conveying unit 122 conveys the material input by the material input unit 121 to the manufacturing unit 123. Further, the conveying unit 122 conveys the product (member) manufactured by the manufacturing unit 123 to the product output unit 124. The conveying unit 122 is realized by, for example, a conveyor, an actuator, and / or a motor, etc., but is not particularly limited.

[0078] The manufacturing unit 123 produces (manufactures) members using the input material. The manufacturing unit 123 is, for example, a device that performs at least one process related to manufacturing such as component assembly, adhesion, welding, etc.

[0079] The product output unit 124 is a device that outputs the members (work-in-progress) produced by the manufacturing unit 123.

[0080] Note that the material input unit 121, the conveying unit 122, the manufacturing unit 123, and the product output unit 124 each include one or more sensors for detecting the processing state of each unit. The output result of the sensor is output to the processing unit 112, the operation time specifying unit 131, the stop time specifying unit 132, and / or the stop cause specifying unit 141.

[0081] The operation time specifying unit 131 specifies the operation time of the manufacturing facility 100. Specifically, the operation time specifying unit 131 specifies the time when the production of the member starts based on the output result of each sensor as the operation time. The operation time specifying unit 131 specifies the operation time each time the production of the member starts and resumes (recovers) after stopping.

[0082] The stop time specifying unit 132 specifies the stop time of the manufacturing facility 100.

The stop time specifying unit 132 specifies the stop time each time the manufacturing facility 100 stops.

[0083] The stop cause identification unit 141 identifies the stop causes of the manufacturing facility 100.

The storage unit 211 is realized by a non-volatile storage device such as an HDD or a semiconductor memory. Note that the storage unit 211 may be realized by a common hardware resource with at least one of the equipment information storage unit 221, the work information storage unit 222, and the member information storage unit 223.

[0090] The processing unit 212 performs processing for controlling the overall operation of the restoration equipment notification device 200. The processing unit 212 is realized by, for example, a processor. The processing unit 212 generates instructions for controlling each component of the restoration equipment notification device 200 and outputs them to each component.

[0091] The communication unit 213 is a communication interface for the restoration equipment notification device 200 to communicate with other devices. The communication unit 213 receives, for example, equipment names, types of members, stop times, stop causes, operation times, work start times, etc. by communicating with each of a plurality of manufacturing facilities 100. In addition, the communication unit 213 transmits the notification information created by the notification unit 260 by communicating with the terminal device 300.

[0092] The input unit 214 receives operation inputs from workers, administrators, etc. to the restoration equipment notification device 200.

The member information storage unit 223 is realized by a non-volatile storage device such as an HDD or a semiconductor memory.

[0097] The model creation unit 230 creates a learning model by performing machine learning. The learning model is, for example, a regression model based on Bayesian estimation. Specifically, the model creation unit 230 creates a worker model for the recovery work for each worker. The worker model is a model that estimates and outputs the working time distribution when, for example, the worker name (identification number), the stop factor, and the working time of the worker are input as input data. In addition, the model creation unit 230 creates a production capacity model for each manufacturing facility 100. The production capacity model is a model that estimates and outputs the operating time distribution for each stop factor when the facility name (identification number) of the manufacturing facility, the type of member, the stop factor, and the operating time are input as input data. Note that the production capacity model may use the production quantity as input data instead of the operating time, and estimate and output the production quantity distribution for each stop factor.

[0098] The model creation unit 230 creates a simulation model for the subsequent process. The simulation model for the subsequent process is a regression model that integrates the worker model and the production capacity model. The simulation model for the subsequent process is a model that estimates and outputs the operating time distribution or the production quantity distribution for each stop factor when information related to the subsequent process is input as input data.

[0099] When two or more current process facilities are stopped, the estimation unit 240 estimates the productivity of the subsequent process facility that uses at least one of the members produced by the stopped current process facility. Specifically, the estimation unit 240 estimates the productivity of the subsequent process facility by using the production capacity model or the subsequent process simulation model created by the model creation unit 230. An example of specific productivity estimation will be described later.

[0100] The specific part 250 specifies, based on the productivity estimated by the estimation part 240, one of the two or more current process facilities that are stopped as the facility to be subject to the restoration work. Specifically, the specific part 250 sets the priority of each of the two or more current process facilities that are stopped, and specifies the facility whose set priority is higher than the threshold value as the facility to be subject to the work. The threshold value is a predetermined value, but is not limited thereto. The threshold value may be the priority set for one of the two or more current process facilities that are stopped. That is, the specific part 250 may compare the priorities set for each of the two or more current process facilities that are stopped, and specify the facility with a higher priority than others as the facility to be subject to the work. For example, the specific part 250 specifies the facility with the highest set priority as the facility to be subject to the work. Examples of the specific priority setting process and the facility to be subject to the work specifying process will be described later.

[0101] The notification part 260 notifies the facility to be subject to the work specified by the specific part 250. Specifically, the notification part 260 creates notification information indicating the facility to be subject to the work specified by the specific part 250, and transmits it to the terminal device 300 held by the worker 2A. The notification information may include not only the facility to be subject to the work, but also all the current process facilities that are stopped and the priorities set for each of them.

[0102] The model creation part 230, the estimation part 240, the specific part 250, and the notification part 260 are each realized by a dedicated integrated circuit or the like, but are not limited thereto. The processing performed by each of the model creation part 230, the estimation part 240, the specific part 250, and the notification part 260 may be performed by the processing part 212 executing a predetermined program.

[0103] Also, the configuration of the restoration facility notification device 200 is not limited to the example shown in FIG. 5. For example, the restoration facility notification device 200 may not include the model creation part 230. In this case, the estimation part 240 may estimate the productivity based on statistical processing instead of machine learning.

[0107] The processing unit 312 performs processing for controlling the overall operation of the terminal device 300. The processing unit 312 is realized by, for example, a processor. The processing unit 312 generates instructions for controlling each component of the terminal device 300 and outputs them to each component. For example, the processing unit 312 generates a notification image based on the notification information acquired via the communication unit 313. Alternatively, the processing unit 312 may generate audio including the information included in the notification image. Further, the processing unit 312 generates a control signal for vibrating the vibration unit 317 and outputs it to the vibration unit 317.

[0108] The communication unit 313 is a communication interface for the terminal device 300 to communicate with other devices.

[0111] The voice output unit 316 is a speaker that outputs voice generated based on the notification information transmitted from the restoration equipment notification device 200.

[0112] The vibration unit 317 vibrates the terminal device 300 by vibrating itself. The vibration unit 317 may have variable vibration time, vibration frequency, vibration intensity, etc.

[0113] Note that the configuration of the terminal device 300 is not limited to the example shown in FIG. 6. For example, the terminal device 300 may not include one of the display unit 315 and the voice output unit 316. Also, the terminal device 300 may not include the vibration unit 317.

[0114] [1-3. Information Processed by the Restoration Equipment Notification System] Subsequently, the information processed by the restoration equipment notification system 10 according to the present embodiment will be described with reference to FIGS. 7 to 15.

[0115] [1-3-1. Equipment Information] FIG. 7 is a diagram showing an example of facility information. The facility information is information including the operation and stop status of each manufacturing facility 100, as well as the stop cause and the like. The facility information is information stored in the facility information storage unit 221 of the recovery facility notification device 200 based on the information transmitted from each manufacturing facility 100.

The stop time is the time when the stop occurred. The operation time is the time when the stopped manufacturing facility 100 started operating, and is also referred to as the recovery time.

[0117] The stop duration is the time (period) during which the manufacturing facility 100 is stopped. The stop duration is calculated by subtracting the stop time from the operation time. The failure interval time corresponds to the operation time of the manufacturing facility 100 and is the time (period) from the start of the previous operation to the stop. The failure interval time is calculated by subtracting the previous operation time from the stop time.

[0118] The production quantity is the number of members produced by the stopped manufacturing facility 100 during operation. The stop cause is the cause for which the stopped manufacturing facility 100 stopped.

As shown in FIG. 8, the work information includes, for example, facility name, member identifier, stop time, operation time, stop time, stop cause, work start time, facility standby time, and work time.

[0121] The facility name, member identifier, stop time, operation time, stop time, and stop cause are the same as the facility information shown in FIG. 7. Therefore, the work information may be integrated with the facility information and stored in a database.

[0122] The work start time is the time when the worker starts the recovery work. The facility standby time is the elapsed time from when the manufacturing facility 100 stops until the recovery work starts. The facility standby time is calculated by subtracting the stop time from the work start time. The work time is the time required by the worker for the recovery work. The work time is calculated by subtracting the work start time from the operation time. Alternatively, the work time may be calculated by subtracting the facility standby time from the stop time.

[0123] The work information is used as learning data when creating a worker model for each manufacturing facility 100 (learning phase). Also, the work information is used as input data for the worker model of each manufacturing facility 100 when estimating the productivity of each manufacturing facility 100 (usage phase).

[0124] [1-3-3. Member Type Information] FIG. 9 is a diagram showing an example of member type information. The member type information is information indicating the types of members produced by the current process equipment. The member type information is information stored in the member information storage unit 223 of the restoration equipment notification device 200 based on information transmitted from each manufacturing equipment 100 (specifically, the current process equipment). Note that the member type information may be information generated based on a production plan input via the input unit 214.

[0125] The member information storage unit 223 stores the member type information in a database. One record is recorded for each manufacturing equipment 100. When one manufacturing equipment 100 produces a plurality of members, a plurality of (the number of members) records are recorded for one manufacturing equipment 100.

[0126] As shown in FIG. 9, the member type information includes, for example, the current process equipment name and the member identifier. The current process equipment name is identification information of the current process equipment that generates the type of member indicated by the member identifier. The member identifier is an identifier uniquely assigned to the type of member.

[0130] As shown in FIG. 10, the member - facility correspondence information includes, for example, a member identifier and a post - process facility name. The member identifier is an identifier uniquely assigned to the type of member. The post - process facility name is identification information of the post - process facility that uses the member of the type indicated by the member identifier as a material.

[0131] FIG. 11 is a diagram showing another example of the member - facility correspondence information. The member - facility correspondence information shown in FIG. 11 is integrated and stored in a database with the member type information shown in FIG. 9 and the member - facility correspondence information shown in FIG. 10. For example, the record in the first row indicates that the type of member produced by the current - process facility represented by "F0561" is represented by "X12313108841", and this member is used in two post - process facilities represented by "XY02" and "XY03". Note that when one type of member is used in three or more post - process facilities, the number of items of the post - process facilities increases.

[0132] The component equipment correspondence information is used for the estimation process of the productivity of the post-process equipment. Specifically, the component equipment correspondence information is used for the estimation process of the required number of components. Also, the component equipment correspondence information may be used as learning data when creating a simulation model for the post-process (learning phase) of each manufacturing equipment 100.

[0135] As shown in FIG. 12, the component feature information includes, for example, a component identifier, height, and polarity. Here, it is assumed that the component is an electrode used for an electrolytic capacitor. The height represents the length of the electrode, and the polarity represents the polarity of the electrode. The component is not limited to the electrode of the capacitor, and the items of the component feature information can be appropriately changed according to the component.

[0136] [1-3-6. Unused Information] FIG. 13 is a diagram showing an example of unused information. The unused information is information indicating the number of unused components among the components that have been produced by the current process equipment. The unused information is information stored in the component information storage unit 223 of the recovery equipment notification device 200 based on the information transmitted from each manufacturing equipment 100. Note that the unused information may be generated based on the output from the sensor when a sensor is provided in the component storage area.

[0137] The unused information storage unit 223 stores the unused information in a database. One record is recorded for each type of member. Alternatively, one record may be recorded for each member storage location.

[0138] As shown in FIG. 13, the unused information includes a member identifier and a member quantity. The member identifier is an identifier uniquely assigned to the type of member. The member quantity indicates the unused quantity for each type of member. The unused quantity is the number of members produced by the current process equipment and not yet used in the subsequent process equipment. The unused quantity is calculated by subtracting the quantity used in the subsequent process equipment from the production quantity of the current process equipment.

[0139] The unused information is used to estimate the productivity of the subsequent process equipment.

Alternatively, the unused information may be used as learning data when creating a simulation model of the subsequent process for each manufacturing equipment 100 (learning phase). Also, the unused information may be used as input data for the simulation model of the subsequent process when estimating the productivity of each manufacturing equipment 100 (usage phase).

[0140] [1-3-7. Capacity Information] FIG. 14 is a diagram showing an example of the capacity information of the subsequent process equipment. The capacity information is information indicating the production capacity (for example, processing capacity) of the subsequent process equipment. The capacity information is information generated based on information transmitted from each manufacturing equipment 100 (specifically, the subsequent process equipment). The capacity information is stored in the equipment information storage unit 221, for example. The equipment information storage unit 221 stores the capacity information in a database. One record is recorded for each manufacturing equipment 100.

[0141] As shown in FIG. 14, the capacity information includes the name of the subsequent process equipment and the average processing time per unit (unit: second). The average processing time per unit is the average value of the time required for the subsequent process equipment to produce (process) one member. For example, the average processing time is calculated by dividing the number of products produced within a certain period by the subsequent process equipment by that period.

[0142] Note that the capacity information may include statistical information such as variance, or probability distribution and its parameters, instead of or in addition to the average processing time. Further, the capacity information may be the empirical distribution information of the performance data obtained by aggregating the operating status (downtime and failure interval time) of the subsequent process equipment.

[0143] Alternatively, as shown in FIG. 15, the capacity information may include the average production number per hour. FIG. 15 is a diagram showing another example of the capacity information of the subsequent process equipment. The capacity information may be statistical information such as variance, or probability distribution and its parameters, instead of or in addition to the average production number. Further, the capacity information may include the empirical distribution information of the performance data obtained by aggregating the production numbers of the subsequent process equipment.

[0144] Further, the capacity information may include the stop cause of the subsequent process equipment. By considering the stop cause, when the subsequent process equipment is in a failure state, the average processing time or the average production number may be set to 0 regardless of the performance data.

[0145] The capacity information is used to estimate the productivity of the subsequent process equipment. Specifically, the capacity information is used for the estimation process of the required number of members. Alternatively, the capacity information may be used as learning data when creating the subsequent process simulation model (learning phase) of each manufacturing equipment 100. Further, the capacity information may be used as input data for the subsequent process simulation model when estimating the productivity of each manufacturing equipment 100 (usage phase).

[0146] [1-4. Operation] Next, the operation of the recovery equipment notification system 10 according to the present embodiment will be described. The operation of the recovery equipment notification system 10 according to the present embodiment mainly includes two processes: a learning phase and a usage phase. First, the outlines of the processes in the learning phase and the usage phase will be described using the sequence diagrams in FIGS. 16 and 17.

[0147] [1-4-1. Learning Phase] First, the outline of the process in the learning phase will be described with reference to FIG. 16. FIG. 16 is a sequence diagram showing the information recording process and the model creation process (learning phase) by the recovery equipment notification system 10 according to the present embodiment.

[0148] In FIG. 16, one manufacturing facility 100 in the current process (current process facility) and one manufacturing facility 100 in the subsequent process (subsequent process facility) are each illustrated as representatives. The operations described below are performed in any case of a plurality of current process facilities and a plurality of subsequent process facilities.

[0149] As shown in FIG. 16, when a manufacturing stop occurs in the current process facility (S1a), the current process facility transmits stop information regarding the stop of the current process facility to the recovery equipment notification device (S2a). The recovery equipment notification device 200 receives the stop information transmitted from the current process facility and records the received stop information (S3a).

[0150] When a manufacturing stop occurs in the subsequent process facility (S1b), similar to the case of the current process facility, the subsequent process facility transmits stop information regarding the stop of the subsequent process facility to the recovery equipment notification device (S2b). The recovery equipment notification device 200 receives the stop information transmitted from the subsequent process facility and records the received stop information (S3b).

[0151] Here, an example is shown in which the subsequent process facility stops after the current process facility stops, but it is not limited to this. There may be a case where the current process facility stops after the subsequent process facility stops, or a case where the current process facility and the subsequent process facility stop substantially simultaneously. In any case, the transmission of stop information and the recording of information are performed.

[0152] When an operator arrives at the post-process equipment (S4b), the post-process equipment transmits operator information regarding the operator who performs the restoration work of the post-process equipment (S5b). The restoration equipment notification device 200 records the transmitted operator information (S6b).

[0153] When the restoration work is completed and the manufacturing of the post-process equipment is started (S7b), the post-process equipment transmits restoration information regarding the restoration (start of manufacturing) of the post-process equipment (S8b). The restoration equipment notification device 200 records the transmitted restoration information (S9b).

[0154] Furthermore, when an operator arrives at the current-process equipment (S4a), the current-process equipment transmits operator information regarding the operator who performs the restoration work of the current-process equipment (S5a). The restoration equipment notification device 200 records the transmitted operator information (S6a). When the restoration work is completed and the manufacturing of the current-process equipment is started (S7a), the current-process equipment transmits restoration information regarding the restoration (start of manufacturing) of the current-process equipment (S8a). The restoration equipment notification device 200 records the transmitted restoration information (S9a).

[0155] Here, an example is shown in which the restoration work of the post-process equipment is executed before the current-process equipment, but it is not limited to this. There may be a case where the restoration work of the current-process equipment is executed before the post-process equipment. When there are a plurality of operators, the restoration work of the current-process equipment and the restoration work of the post-process equipment may be performed simultaneously. In any case, the transmission of the operator information and the restoration information and the recording of the information are performed.

[0156] As described above, each time a stop of the equipment occurs, each time an operator arrives (each time the restoration work is started), and each time the equipment starts operating, the restoration equipment notification device 200 acquires and records the information. As a result, the equipment information shown in FIG. 7 and the work information shown in FIG. 8 are respectively made into a database and recorded.

[0157] Using the information for a certain period, the model creation unit 230 of the restoration equipment notification device 200 creates a learning model by performing machine learning (S10). A specific example of creating a learning model will be described later with reference to FIGS. 19 and 20.

[0158] [1-4-2. Usage Phase] Next, the outline of the processing in the usage phase will be described with reference to FIG. 17. FIG. 17 is a sequence diagram showing the restoration equipment notification process (usage phase) by the restoration equipment notification system 10 according to the present embodiment.

[0159] In FIG. 17, two of the plurality of manufacturing facilities 100 (current process facilities) in the current process are shown as representatives. The operations described below are performed in any case of the plurality of current process facilities.

[0160] As shown in FIG. 17, when production stops in the manufacturing facility 100 in the current process (here, the current process facility A) (S11a), the current process facility A transmits the stop information regarding the current process facility A to the restoration equipment notification device 200 (S12a). Since the current process facility A has stopped and has been newly added as a candidate for the restoration work, the restoration equipment notification device 200 identifies the equipment to be subjected to the restoration work (S13a), and transmits the notification information including the identification information of the identified target equipment to the terminal device 300 (S14a). The terminal device 300 displays the notification information transmitted from the restoration equipment notification device 200 (S15a). Note that the target equipment indicated by the notification information at this time is not limited to the current process facility A, and may be a current process facility other than the current process facility A.

[0161] When a manufacturing stop occurs in the current process manufacturing equipment 100 (hereafter referred to as current process equipment B), which is different from the current process equipment A (S11b), the current process equipment B transmits stop information regarding the current process equipment B to the recovery equipment notification device 200 (S12b). Since the current process equipment B has stopped and has been newly added as a candidate for recovery work, the recovery equipment notification device 200 identifies the equipment to be subjected to the recovery work (S13b), and transmits notification information including the identification information of the identified target equipment to the terminal device 300 (S14b). The terminal device 300 displays the notification information transmitted from the recovery equipment notification device 200 (S15b). Assume that the target equipment indicated by the notification information at this time is the current process equipment B. In this case, the operator performs the recovery work on the current process equipment B.

[0162] Also, when the manufacturing of the current process equipment B is started due to the recovery work being carried out (S16b), the current process equipment B transmits recovery information regarding the recovery (start of manufacturing) of the current process equipment B (S17b). Since the current process equipment B has been recovered and has dropped out of the candidate for recovery work, the recovery equipment notification device 200 identifies the equipment to be subjected to the recovery work (S18b), and transmits notification information including the identification information of the identified target equipment to the terminal device 300 (S19b). The terminal device 300 displays the notification information transmitted from the recovery equipment notification device 200 (S20b). Assume that the target equipment indicated by the notification information at this time is the current process equipment A. In this case, the operator performs the recovery work on the current process equipment A.

[0163] When the manufacturing of the current process equipment A is started due to the recovery work being carried out (S16a), the current process equipment A transmits recovery information regarding the recovery (start of manufacturing) of the current process equipment A (S17a). Since the current process equipment A has been recovered and has dropped out of the candidate for recovery work, the recovery equipment notification device 200 identifies the equipment to be subjected to the recovery work (S18a), and transmits notification information including the identification information of the identified target equipment to the terminal device 300 (S19a). The terminal device 300 displays the notification information transmitted from the recovery equipment notification device 200 (S20a).

[0164] As described above, according to the restoration equipment notification system 10 according to the present embodiment, every time the current process equipment stops and every time the stopped current process equipment is restored, identification and notification of the equipment to be restored are performed. That is, the restoration equipment notification system 10 identifies and notifies the target equipment every time an increase or decrease in the stopped manufacturing equipment 100 occurs. Thereby, according to changes in the operating status of the production system, it is possible to notify the operator of the appropriate target equipment for which restoration work should be performed, so it is excellent in real-time performance and can support improvement in productivity.

[0165] [1-5. Specific Processing] Subsequently, details of the specific processing by the restoration equipment notification system 10 according to the present embodiment will be described with reference to FIGS. 18 to 23.

[0166] [1-5-1. Information Recording Processing] First, the information recording process (learning phase) by the restoration equipment notification system 10 will be described with reference to FIG. 18. FIG. 18 is a flowchart showing the information recording process by the restoration equipment notification system 10 according to the present embodiment. FIG. 18 corresponds to steps S1a to S9a and S1b to S9b in the sequence diagram shown in FIG. 16.

[0167] First, when the stop of the manufacturing equipment 100 occurs (Yes in S101), the restoration equipment notification device 200 receives the stop information transmitted from the manufacturing equipment 100 and records it in the equipment information storage unit 221 (S102). The stop information includes a stop notification indicating that the manufacturing equipment 100 has stopped, the stop and operation status of the manufacturing equipment 100, and the stop cause and member type, etc. The stop and operation status is, for example, equipment name, stop time, production quantity, and operation time, etc.

[0168] Specifically, when the manufacturing facility 100 stops, in the manufacturing facility 100, the stop time specifying unit 132 specifies the stop time, and the stop cause specifying unit 141 specifies the stop cause. Further, the processing unit 112 calculates the production quantity of the members produced until the stop, specifically, the number of members output by the product output unit 124. Further, the processing unit 112 reads out the facility name stored in the storage unit 111 and the member identifier of the member being produced. The processing unit 112 transmits stop information including the stop time, the stop cause, the production quantity, the facility name, and the member identifier, etc., to the restoration facility notification device 200 via the communication unit 113. In the restoration facility notification device 200, the stop information received via the communication unit 213 is recorded in the facility information storage unit 221. At this time, the processing unit 212 of the restoration facility notification device 200 calculates the stop time and the failure interval time, and records them in the facility information storage unit 221.

[0169] When the manufacturing facility 100 does not stop (No in S101), the recording process of the stop information (S102) is omitted.

[0170] Next, when an operator arrives at the stopped manufacturing facility 100 (Yes in S103), the restoration facility notification device 200 receives the operator information transmitted from the manufacturing facility 100 or the terminal device 300, and records it in the work information storage unit 222 (S104). The operator information includes the facility name of the manufacturing facility 100 targeted for the restoration work, the name of the operator performing the restoration work (operator name), the time when the operator started the restoration work (work start time), etc.

[0171] Specifically, when an operator arrives, the operator inputs the fact of arrival via the input unit 114 of the manufacturing facility 100, that is, inputs the start of the recovery work. The processing unit 112 determines the time input at the input unit 114 as the start time of the work. Further, the processing unit 112 reads out the equipment name stored in the storage unit 111. The processing unit 112 transmits the start time of the work and the equipment name to the recovery equipment notification device 200 via the communication unit 113. Also, the processing unit 312 of the terminal device 300 reads out the operator name from the storage unit 311, and transmits the read operator name to the recovery equipment notification device 200 via the communication unit 313. Note that the input of the start of the recovery work may be performed via the input unit 314 of the terminal device 300 held by the operator, and the start time of the work may be transmitted from the terminal device 300.

[0172] When the operator does not arrive at the manufacturing facility 100 (No in S103), the recording process of the operator information (S104) is omitted.

[0173] Next, when the stopped manufacturing facility 100 starts manufacturing (Yes in S105), the recovery equipment notification device 200 receives the recovery information transmitted from the manufacturing facility 100 and records it in the work information storage unit 222 (S106). The recovery information includes a recovery notification indicating that the manufacturing facility 100 has recovered, as well as the operation time (recovery time) of the manufacturing facility 100 and the equipment name.

[0174] Specifically, when the manufacturing facility 100 starts manufacturing, in the manufacturing facility 100, the operation time specifying unit 131 specifies the operation time. The processing unit 112 reads out the equipment name stored in the storage unit 111, and transmits the recovery information including the read equipment name and operation time to the recovery equipment notification device 200 via the communication unit 113. In the recovery equipment notification device 200, the recovery information received via the communication unit 213 is recorded in the work information storage unit 222 and the equipment information storage unit 221.

[0175] Next, the processing unit 212 of the restoration equipment notification device 200 calculates the downtime (equipment standby time) of the manufacturing equipment 100 based on the acquired worker information and restoration information, and records the calculated downtime in the work information storage unit 222 (S107). The processing unit 212 calculates the downtime by subtracting the stop time from the work start time.

[0176] Next, the processing unit 212 of the restoration equipment notification device 200 calculates the working time of the manufacturing equipment 100 based on the acquired worker information and restoration information, and records the calculated working time in the work information storage unit 222 (S108). The processing unit 212 calculates the working time by subtracting the work start time from the operating time.

[0177] As shown in FIG. 16, the above processing is performed each time the manufacturing equipment 100 stops. As a result, stop information and restoration information are accumulated in the equipment information storage unit 221 of the restoration equipment notification device 200, and a database of equipment information shown in FIG. 7 is constructed. In addition, worker information and restoration information are accumulated in the work information storage unit 222 of the restoration equipment notification device 200, and a database of work information shown in FIG. 8 is constructed.

[0178] [1-5-2. Model Creation Process] Next, the model creation process (learning phase) by the restoration equipment notification system 10 will be described with reference to FIG. 19. FIG. 19 is a flowchart showing the model creation process by the restoration equipment notification system 10 according to the present embodiment. FIG. 19 corresponds to step S10 in the sequence diagram shown in FIG. 16.

[0179] First, the model creation unit 230 of the restoration equipment notification device 200 acquires equipment information and work information of the subsequent process for a predetermined period (S111). Specifically, the model creation unit 230 reads out equipment information regarding the subsequent process equipment for a predetermined period from the equipment information storage unit 221, and reads out work information regarding the subsequent process equipment for a predetermined period from the work information storage unit 222.

[0180] Incidentally, the predetermined period is a relatively long period such as one day, one week, or one month, but is not particularly limited. By securing a longer period, the accuracy of machine learning can be improved. When the period is short, the processing time required for machine learning can be shortened.

[0181] The model creation unit 230 creates a worker model for the subsequent process based on the acquired information (S112). The worker model for the subsequent process is created for each worker and is a model for estimating the work time distribution when the corresponding worker performs a recovery operation on the subsequent process equipment.

[0182] For example, the model creation unit 230 performs machine learning using, as input data, the work time of the recovery operation performed by a worker, as well as the cause of stoppage, equipment name, and type of member of the subsequent process equipment targeted for the recovery operation, for one worker, thereby creating a worker model. The worker model is, for example, a model that estimates and outputs a work time distribution when the cause of stoppage, equipment name, and type of member of the subsequent process equipment are input.

[0183] The model creation unit 230 repeatedly performs steps S111 and S112 until worker models for all workers who perform recovery operations on a plurality of subsequent process equipment are created (No in S113).

[0184] After worker models for all workers in the subsequent process are created (Yes in S113), the model creation unit 230 acquires equipment information for the subsequent process for a predetermined period (S114). Specifically, the model creation unit 230 reads out equipment information regarding the subsequent process equipment for a predetermined period from the equipment information storage unit 221.

[0185] The model creation unit 230 creates a production capacity model for the subsequent process equipment based on the acquired information (S115). The production capacity model is created for each subsequent process equipment and is a model for estimating the productivity of the corresponding subsequent process equipment.

[0186] For example, the model creation unit 230 creates a production capacity model by performing machine learning on one post-process facility using the operation time, stop time, facility name, stop cause, type of member, and production quantity of the post-process facility as input data. The production capacity model is, for example, a model that outputs an operation time distribution or a production quantity distribution when the operation time, stop time, facility name, stop cause, and type of member of the post-process facility are input.

[0187] The model creation unit 230 repeats steps S114 and S115 until production capacity models for all post-process facilities are created (No in S116). When production capacity models for all post-process facilities are created (Yes in S116), the processing in the learning phase ends.

[0188] Note that in FIG. 19, an example of creating a production capacity model after creating a worker model is shown, but it is not limited to this. A worker model may be created after creating a production capacity model. Alternatively, the creation processes of the two models may be performed simultaneously in parallel.

[0189] Further, the model creation unit 230 may create a simulation model for the post-process after integrating the two models. FIG. 20 is a flowchart showing another example of the model creation process for the post-process by the recovery facility notification system 10 according to the present embodiment.

[0190] In the example shown in FIG. 20, the processing in steps S111 to S116 is the same as that in FIG. 19. After worker models for the post-process for all workers and production capacity models for all post-process facilities are created (Yes in S116), the model creation unit 230 acquires the priority rule for the post-process (S117). The priority rule is information indicating conditions for setting the priority of the recovery work. For example, the priority is set based on the productivity of the post-process facility. Specifically, the priority is set based on the number of members required by the post-process facility in a certain period (required number of members). The priority rule defines, for example, the method for setting the priority and the method for calculating the required number of members.

[0191] Based on the priority rules, the model creation unit 230 integrates the worker model and the production capacity model to create a simulation model for the subsequent process (S118). The simulation model for the subsequent process is, for example, a model that sets and outputs priorities for each of the plurality of manufacturing facilities 100 that are stopped based on the priority rules when information regarding each of the stopped facilities and the workers performing the recovery work is input.

[0192] [1-5-3. Recovery Equipment Notification Processing] Next, the recovery equipment notification processing (usage phase) by the recovery equipment notification system 10 will be described with reference to FIG. 21. FIG. 21 is a flowchart showing the recovery equipment notification processing by the recovery equipment notification system 10 according to the present embodiment. FIG. 21 corresponds to each step in the sequence diagram shown in FIG. 17.

[0193] As shown in FIG. 21, until a new operation (recovery) of the current process equipment or a new stop of the current process equipment occurs (No in S121 and No in S122), the recovery equipment notification device 200 waits. When a new stop of the current process equipment occurs (Yes in S122), the estimation unit 240 of the recovery equipment notification device 200 estimates the required number of members (S123). The required number of members is the number of members produced by the corresponding current process equipment that is required by the subsequent process equipment within a predetermined period. The required number of members is an example of the productivity of the subsequent process equipment. The specific estimation process of the required number of members will be described later with reference to FIG. 22.

[0194] Next, the specifying unit 250 of the recovery equipment notification device 200 sets the priority of the recovery work based on the estimated required number of members (S124). Specifically, the specifying unit 250 sets a higher priority as the required number of members increases. For example, the specifying unit 250 compares the estimated required number of members of the other stopped current process equipment with the currently estimated required number of members, and sets the priority of the equipment with a larger required number of members higher than the priority of the equipment with a smaller required number of members. Note that the specifying unit 250 may set the required number of members itself as the priority. Steps S123 and S124 are repeated until the priorities of all the stopped current process equipment are set (No in S125).

[0195] After priorities are set for all current process facilities that are stopped (Yes in S125), the notification unit 260 notifies the terminal device 300 of all current process facilities that are stopped and their priorities via the communication unit 213 (S126). This notification is also performed when a new operation of the current process facility occurs (Yes in S121). That is, when the number of current process facilities that are stopped decreases due to the execution of the recovery work, the notification is performed for all current process facilities that are stopped except for the facilities that have started operating.

[0196] [1-5-4. Estimation Process of the Number of Necessary Components] Next, the estimation process of the number of necessary components (S123) will be described with reference to FIG. 22. FIG. 22 is a flowchart showing the estimation process of the number of necessary components (S123) by the recovery facility notification system 10 according to the present embodiment. Hereinafter, the correspondence relationship between the current process facilities and the subsequent process facilities shown in FIG. 2 will be taken as an example for explanation.

[0197] As shown in FIG. 22, the estimation unit 240 of the recovery facility notification device 200 specifies the components produced by the current process facilities that are stopped as target components (S131). Specifically, the estimation unit 240 specifies the target components based on the component type information included in the stop information transmitted from the current process facilities. For example, when the facility B in FIG. 2 is stopped, it is specified that the target component is component b.

[0198] Next, the estimation unit 240 specifies the subsequent process facilities that use the target components (S132). Specifically, the estimation unit 240 refers to the component-facility correspondence information (for example, FIGS. 10 or 11) stored in the component information storage unit 223 based on the type information of the components included in the stop information transmitted from the current process facilities to specify the subsequent process facilities. For example, as the subsequent process facility that uses the component b produced by the facility B in FIG. 2, the facility X is specified. As the subsequent process facilities that use the component d produced by the facility D in FIG. 2, two facilities, namely the facility Y and the facility Z, are specified.

[0199] Next, the estimation unit 240 acquires the operating and stopping status of the identified post-process equipment (S133). Specifically, the estimation unit 240 refers to the equipment information stored in the equipment information storage unit 221 based on the equipment name of the identified post-process equipment to acquire whether the identified post-process equipment is operating or stopped. Alternatively, the estimation unit 240 may communicate with the identified post-process equipment via the communication unit 213 to acquire the operating and stopping status.

[0200] If the post-process equipment is stopped (Yes in S134), the estimation unit 240 acquires the cause of the stop of the post-process equipment (S135). Specifically, the estimation unit 240 refers to the equipment information stored in the equipment information storage unit 221 based on the equipment name of the identified post-process equipment to acquire the cause of the stop of the identified post-process equipment.

[0201] If the cause of the stop is not a planned stop (No in S136), or if the post-process equipment is not stopped (No in S134), the estimation unit 240 estimates the number of members (usage number) used by the post-process equipment within a predetermined period (S137). The predetermined period here is shorter than the period of the data used for creating the learning model and is a relatively short period such as several seconds, several minutes, or several tens of minutes. The estimation unit 240 uses the production capacity model of the post-process equipment to estimate the usage number.

[0202] Next, the estimation unit 240 adds the estimated usage number to the usage number of the target member within a predetermined period (S138). This addition is omitted when only one post-process equipment uses the target member.

[0203] If the cause of the stop is a planned stop (Yes in S136), the estimation unit 240 sets the usage number of the target member by the target post-process equipment to 0 (S139). For example, since equipment X in FIG. 2 is in planned stop, the usage number of member b by equipment X is set to 0. Note that it is not limited to planned stop, and the estimation unit 240 may set the usage number of the target member to 0 when a predetermined condition is satisfied. The predetermined condition is, for example, being under maintenance, being under failure, or not operating for a long period equal to or longer than a predetermined value.

[0204] For all subsequent process equipment that uses the target member, the processes of steps S133 to S139 are repeatedly performed (No at S140). When a plurality of subsequent process equipment uses the target member, by repeatedly performing addition (S138), the usage number of the target member can be appropriately calculated according to the actual situation. For example, in the case of member d in FIG. 2, the value obtained by adding the usage number in equipment Y and the usage number in equipment Z is calculated as the usage number of the target member.

[0205] After calculating the usage number of the member for all subsequent process equipment that uses the target member (Yes at S140), the estimation unit 240 acquires the unused number of the member by the subsequent process equipment (S141). Specifically, the estimation unit 240 refers to the unused information (for example, FIG. 13) based on the type of the target member to acquire the unused number. For example, in the case of member d shown in FIG. 2, the unused number is 1.

[0206] Next, the estimation unit 240 calculates the value obtained by subtracting the unused number from the usage number of the target member as the required number of members of the target member (S142).

[0207] The above processes are performed for all of the current process equipment that is stopped as shown in step S125 of FIG. 21. In the example of FIG. 2, for each of the equipment B, D, and E in the current process, the required number of members of the members produced by each equipment is calculated.

[0208] Hereinafter, an example in which the usage number of the member by each subsequent process equipment is estimated as follows will be described.

[0209] Usage number of member a by equipment X = 0 Usage number of member b by equipment X = 0 Usage number of member c by equipment Y = 5 Usage number of member d by equipment Y = 5 Usage number of member c by equipment Z = 5 Usage number of member d by equipment Z = 5 Usage number of member e by equipment W = 5 Usage number of member f by equipment W = 5

[0210] In this case, the required number of members b, d, and e produced by each of the facilities B, D, and E in the current process is as follows.

[0211] (Required number of member b) = (Usage number of member b by facility X: 0) - (Unused number of member b: 4) = -4 (Required number of member d) = (Usage number of member d by facility Y: 5) + (Usage number of member c by facility Z: 5) - (Unused number of member c: 1) = 9 (Required number of member e) = (Usage number of member e by facility W: 5) - (Unused number of member e: 1) = 4

[0212] In this embodiment, the higher the required number of members, the higher the priority is set. Therefore, in the above example, the priority of the post-process facility D that produces member d with the largest required number of members is set to be the highest.

[0213] For example, as shown in FIG. 12, in the manufacture of a capacitor, if the positive electrode and the negative electrode manufactured in the current process are not aligned, production in the subsequent process cannot be carried out. For this reason, even if the productivity of the current process facility that produces the negative electrode is increased in an attempt to produce the negative electrode despite the shortage of the positive electrode, production in the subsequent process cannot be carried out, and as a result, the productivity cannot be improved. In the recovery facility notification system 10 according to this embodiment, since the priority of the current process facility is determined in consideration of the productivity of the subsequent process facility (specifically, the required number of members in the subsequent process facility), it is possible to lead to an improvement in productivity.

[0214] [1-5-5. Display process] Next, the display process of the notification image performed by the terminal device 300 will be described with reference to FIG. 23. FIG. 23 is a flowchart showing the display process of the notification image by the recovery facility notification system 10 according to this embodiment.

[0215] As shown in FIG. 23, when the processing unit 312 of the terminal device 300 acquires notification information from the recovery facility notification system 10 via the communication unit 313 (Yes in S151), it rearranges the names of the in-operation current process facilities according to the priority included in the notification information (S152). Specifically, the processing unit 312 rearranges the names of the current process facilities in descending order of the priority set for each facility.

[0216] After the rearrangement is completed, or when no new notification information is acquired (No in S151), the processing unit 312 determines whether the highest priority is equal to or higher than the threshold value (S153). The threshold value is set according to the importance of the recovery work.

[0217] When the highest priority is equal to or higher than the threshold value (Yes in S153), the processing unit 312 vibrates the terminal device 300 by controlling the vibration unit 317 (S154). When the terminal device 300 vibrates, even if the worker is performing the recovery work on other facilities, they can notice that a notification has arrived. For example, when the urgency of the recovery work is high enough that the recovery work should be carried out first even if other recovery work is interrupted, the terminal device 300 vibrates. Note that instead of vibration, or in addition to vibration, the processing unit 312 may cause the audio output unit 316 to output a buzzer sound or an alarm sound.

[0218] After vibrating, or when the highest priority is less than the threshold value (No in S153), the processing unit 312 causes the display unit 315 to display a notification image (S155). For example, in the notification image, the names of the in-operation current process facilities are arranged in descending order of the priority of the corresponding facilities. Note that instead of displaying the notification image, or in addition to displaying the notification image, the processing unit 312 may cause the audio output unit 316 to output a voice reading out the name of the facility with the highest priority, or a voice reading out the names of the facilities in descending order of priority. In this case, the presence or absence of the voice, or the volume level, may be changed according to the high or low priority. Also, the high or low priority may be represented by differences in the mode of vibration, such as the number of vibrations or the duration of vibration.

[0219] As described above, in the terminal device 300, each time notification information is acquired, a notification image is displayed. That is, since the notification information is transmitted each time an increase or decrease in the stop of the current process equipment occurs, the notification image is updated each time an increase or decrease in the stop of the current process equipment occurs. Thereby, since an appropriate target equipment is notified according to a change in the situation, it is excellent in real-time property and can support further improvement in productivity.

[0220] (Embodiment 2) Next, Embodiment 2 will be described.

[0221] In Embodiment 2, compared with Embodiment 1, it is different in that the productivity of the current process is further utilized. Below, the description will be centered on the differences from Embodiment 1, and the description of the common points will be omitted or simplified.

[0222] The configuration of the recovery equipment notification system according to Embodiment 2 is the same as that of Embodiment 1. Therefore, below, the operation (recovery equipment notification method) of the recovery equipment notification system according to this embodiment will be described using the configurations of the respective devices shown in FIGS. 3 to 6.

[0223] [2. Operation] The operation of the recovery equipment notification system 10 according to this embodiment, as in Embodiment 1, roughly includes two processes: a learning phase and a use phase. The outline of each phase is as shown in FIGS. 16 and 17.

[0224] [2-1. Model creation process] In this embodiment, in the learning phase, the process of creating a learning model (step S10 in FIG. 16) is different from that in Embodiment 1. Specifically, in creating the learning model, as shown in FIG. 19, in addition to creating a worker model and a production capacity model for the subsequent process, a worker model and a production capacity model for the current process are created.

[0225] FIG. 24 is a flowchart showing the model creation process of the current process by the restoration equipment notification system 10 according to the present embodiment. The process shown in FIG. 24 is executed after the process shown in FIG. 19. Alternatively, the process shown in FIG. 24 may be executed before the process shown in FIG. 19, or may be performed simultaneously in parallel.

[0226] First, the model creation unit 230 of the restoration equipment notification device 200 acquires equipment information and work information of the current process for a predetermined period (S211). Specifically, the model creation unit 230 reads out equipment information regarding the current process equipment for a predetermined period from the equipment information storage unit 221, and reads out work information regarding the current process equipment for a predetermined period from the work information storage unit 222. Note that the predetermined period is, for example, the same period as the data used for creating the learning model of the post-process equipment, but may be a different period.

[0227] The model creation unit 230 creates a worker model of the current process based on the acquired information (S212). The worker model of the current process is created for each worker and is a model for estimating the work time distribution when the corresponding worker performs a restoration operation on the current process equipment. The worker model of the current process is the same as the worker model of the post-process, and the difference is that information regarding the current process is used instead of information regarding the post-process.

[0228] The model creation unit 230 repeats steps S211 and S212 until worker models for all workers who perform restoration operations on a plurality of current process equipment are created (No in S213).

[0229] After worker models for all workers in the current process are created (Yes in S213), the model creation unit 230 acquires equipment information of the current process for a predetermined period (S214). Specifically, the model creation unit 230 reads out equipment information regarding the current process equipment for a predetermined period from the equipment information storage unit 221.

[0230] The model creation unit 230 creates a production capacity model of the current process equipment based on the acquired information (S215). The production capacity model is created for each current process equipment and is a model for estimating the productivity of the corresponding current process equipment. The production capacity model of the current process is the same as that of the subsequent process, except that it is created using information related to the current process instead of information related to the subsequent process.

[0231] The model creation unit 230 repeats steps S214 and S215 until production capacity models for all current process equipment are created (No in S216). When production capacity models for all current process equipment are created (Yes in S216), the processing in the learning phase ends.

[0232] Note that in FIG. 24, an example of creating a production capacity model after creating a worker model is shown, but it is not limited to this. A worker model may be created after creating a production capacity model. Alternatively, the creation processes of the two models may be performed simultaneously in parallel.

[0233] Further, the model creation unit 230 may create a simulation model of the current process by integrating the two models. FIG. 25 is a flowchart showing another example of the model creation process of the current process by the recovery equipment notification system 10 according to the present embodiment.

[0234] In the example shown in FIG. 25, the processing of steps S211 to S216 is the same as that in FIG. 24. After creating a worker model of the current process for all workers and a production capacity model for all current process equipment (Yes in S216), the model creation unit 230 acquires the priority rule of the current process (S217). The priority rule is information indicating conditions for setting the priority of the recovery work. For example, the priority is set based on the target current process equipment and its stop cause (stop code), and the productivity of the current process equipment associated with the stop cause. The priority rule defines, for example, the method of setting the priority.

[0235] The model creation unit 230 creates a simulation model of the current process by integrating the worker model and the production capacity model based on the priority rule (S218). The simulation model of the current process is, for example, a model that sets and outputs priorities for each of the plurality of manufacturing facilities 100 that are stopped based on the priority rule when information regarding each of the stopped facilities and the workers performing the recovery work is input.

[0236] [2-2. Recovery Equipment Notification Process] In the usage phase, the process of identifying the target equipment (steps S13a, S13b, S18b, S18b in FIG. 17) is different from that in the first embodiment. Specifically, in the identification of the target equipment, the recovery equipment notification process shown in FIG. 26 is performed.

[0237] FIG. 26 is a flowchart showing the recovery equipment notification process by the recovery equipment notification system 10 according to the present embodiment.

[0238] As shown in FIG. 26, until a new operation (recovery) of the current process equipment or a new stop of the current process equipment occurs (No in S121 and No in S122), the recovery equipment notification device 200 waits. When a new stop of the current process equipment occurs (Yes in S122), the estimation unit 240 of the recovery equipment notification device 200 estimates the increase amount in production by the stopped current process equipment (S223). The increase amount is the number of members produced in a predetermined period when the stopped current process equipment is recovered. The specific process for calculating the increase amount will be described later with reference to FIG. 27.

[0239] Thereafter, the estimation unit 240 estimates the required number of members (S123). The specific estimation process for the required number of members is the same as that in the first embodiment and is as described with reference to FIG. 22. Note that the estimation of the required number of members (S123) may be performed before the estimation of the increase amount (S223) or may be performed simultaneously.

[0240] Next, the specifying unit 250 of the restoration equipment notification device 200 sets the priority of the restoration work based on the estimated increment and the number of necessary members (S224). Specifically, the specifying unit 250 sets a higher priority as the number of necessary members is larger. The specific process of setting the priority will be described later with reference to FIG. 28.

[0241] Steps S123 and S224 are repeated until the priorities of all the current process equipment that is stopped are set (No in S125).

[0242] After the priorities are set for all the current process equipment that is stopped (Yes in S125), the notification unit 260 notifies the terminal device 300 of all the current process equipment that is stopped and their priorities via the communication unit 213 (S126). This notification is also performed when a new operation of the current process equipment occurs (Yes in S121). That is, when the number of current process equipment that is stopped decreases due to the restoration work being performed, the notification is performed for the current process equipment that has started operating, excluding the equipment that has started operating.

[0243] [2-3. Estimation process of increment] Next, the estimation process of the increment (S223) will be described with reference to FIG. 27. FIG. 27 is a flowchart showing the estimation process of the increment (S223) by the restoration equipment notification system 10 according to the present embodiment.

[0244] First, the estimation unit 240 of the restoration equipment notification device 200 acquires the name of the worker in charge of the restoration work of the current process equipment that is stopped (S231). The assignment of workers to the current process equipment is determined in advance based on the information input via the input unit 214 and is stored in the work information storage unit 222 and the like.

[0245] Next, the estimation unit 240 acquires the cause of the stop of the current process equipment (S232). Specifically, the estimation unit 240 acquires the cause of the stop included in the stop information transmitted from the current process equipment via the communication unit 213.

[0246] Next, the estimation unit 240 estimates the working time required for the worker to restore the current process equipment using the worker model of the current process (S233). Next, the estimation unit 240 estimates the increment when the current process equipment is restored (S234). Specifically, the estimation unit 240 calculates the operating time by subtracting the estimated working time from a predetermined period (the same period as the period set in the estimation of the required number of members in step S123). The estimation unit 240 uses the calculated operating time and utilizes the production capacity model of the current process equipment to estimate the production quantity of the current process equipment as the increment. Note that the estimation unit 240 may estimate the increment using the capacity information of the current process equipment corresponding to the capacity information shown in FIG. 15 instead of the production capacity model.

[0247] Steps S232 to S234 are repeated until the increment of all the current process equipment in the stopped state is calculated (No in S235).

[0248] As described above, for all the current process equipment in the stopped state, the increment of the members when the restoration work is performed can be calculated.

[0249] [2-4. Priority setting process] Next, the priority setting process (S224) will be described with reference to FIG. 28. FIG. 28 is a flowchart showing the priority setting process (S224) by the restoration equipment notification system 10 according to the present embodiment.

[0250] First, when the required number of members of the target current process equipment (the current process equipment targeted in S123) is the largest and the increment is the largest (Yes in S241 and Yes in S242), the specifying unit 250 of the restoration equipment notification device 200 sets the priority of the current process equipment to the highest value (S243). When the required members of the current process equipment are not the largest (No in S241), or when the increment of the current process equipment is not the largest (No in S242), the specifying unit 250 acquires the weight information (S244).

[0251] The weight information is information indicating the weights of each of the current process and the subsequent process. The weight is, for example, a parameter indicating the importance level of the current process and the subsequent process when aiming at improving the productivity of the entire production system. When the current process is more important than the subsequent process, the weight of the current process is set to a value larger than the weight of the subsequent process. When the subsequent process is more important than the current process, the weight of the subsequent process is set to a value larger than the weight of the current process. Note that the weight may be set for each piece of equipment.

[0252] The specific part 250 calculates a subsequent process evaluation value by multiplying the number of required members by the weight of the subsequent process (S245), and calculates a current process evaluation value by multiplying the increment by the weight of the current process (S246). The specific part 250 adds the calculated subsequent process evaluation value and the current process evaluation value, and sets the priority based on the sum value (S247). For example, the specific part 250 sets a higher priority as the sum value is larger.

[0253] The above processing is performed for all of the stopped current process equipment as shown in step S125 of FIG. 26. In the example of FIG. 2, for each of the current process equipment B, D, and E, the number of required members of the members produced by each piece of equipment is calculated.

[0254] Hereinafter, an example in which the increment of the members by the stopped current process equipment is estimated as follows will be described.

[0255] Increment of member b by equipment B = 5 Increment of member d by equipment D = 2 Increment of member e by equipment E = 5

[0256] Also, the number of required members of members b, d, and e produced by each of the current process equipment B, D, and E is assumed as follows, similar to the first embodiment.

[0257] Number of required members of member b = -4 Number of required members of member d = 9 Number of required members of member e = 4

[0258] In this case, when the weight of the current process is 0.3 and the weight of the subsequent process is 0.7, the total values of the respective equipment B, D, and E in the current process are as follows.

[0259] Total value of equipment B = (Increment of member b: 5) × 0.3 + (Required number of members of member b: -4) × 0.7 = -1.3 Total value of equipment D = (Increment of member d: 2) × 0.3 + (Required number of members of member d: 9) × 0.7 = 6.9 Total value of equipment E = (Increment of member e: 5) × 0.3 + (Required number of members of member e: 4) × 0.7 = 4.3

[0260] In this embodiment, the higher the required number of members, the higher the priority is set. In the above example, the priority of the subsequent process equipment D that produces the member d with the largest required number of members is set to be the highest.

[0261] On the other hand, when the weight of the current process is 0.7 and the weight of the subsequent process is 0.3, the total values of the respective equipment B, D, and E in the current process are as follows.

[0262] Total value of equipment B = (Increment of member b: 5) × 0.7 + (Required number of members of member b: -4) × 0.3 = 2.3 Total value of equipment D = (Increment of member d: 2) × 0.7 + (Required number of members of member d: 9) × 0.3 = 4.1 Total value of equipment E = (Increment of member e: 5) × 0.7 + (Required number of members of member e: 4) × 0.3 = 5.7

[0263] In this embodiment, the higher the required number of members, the higher the priority is set. Therefore, in the above example, the priority of the subsequent process equipment E that produces the member e with the largest required number of members is set to be the highest. Thus, depending on the weight, the equipment with the highest priority set may be different. Therefore, according to the weight of each process, a more appropriate priority can be set to support further improvement in productivity.

[0264] Further, according to the present embodiment, the equipment with the highest priority set may be different compared to the case where only the productivity of the post-process equipment (specifically, the number of necessary members) is utilized as in the first embodiment. Therefore, by considering the productivity of the equipment in the current process, further improvement in productivity can be supported.

[0265] Note that the method of setting the priority is not limited to the above-described example. For example, by multi-objective optimization, a priority function that balances the increment in the current process and the number of necessary members in the post-process may be used, and the priority may be set based on the calculated Pareto solution.

[0266] Alternatively, the priority may be set based on a combination of the magnitude relationship of the weights in the current process, the magnitude relationship of the number of necessary members, and the magnitude relationship of the increment.

[0267] FIG. 29 is a diagram showing an example of a priority setting rule by the recovery equipment notification system according to the second embodiment. In FIG. 29, both equipment A and B are current process equipment. When following the rule shown in FIG. 29, the specific part 250 can set the priority as follows.

[0268] The specific part 250, when (i) the weight of the post-process is greater than the weight of the current process, (a) if the number of necessary members of equipment A is more than that of equipment B and the increment of equipment A is less than the increment of equipment B, sets the priority of equipment A higher than the priority of equipment B. Also, the specific part 250, when (i) the weight of the post-process is greater than the weight of the current process, (b) if the number of necessary members of equipment B is more than the number of members of equipment A and the increment of equipment B is less than the increment of equipment A, sets the priority of equipment B higher than the priority of equipment A.

[0269] When (ii) the weight of the current process is greater than the weight of the subsequent process, if (a) the number of required members of Facility A is greater than the number of required members of Facility B and the increase rate of Facility A is less than the increase rate of Facility B, the priority of Facility B is set higher than the priority of Facility A. Also, when (ii) the weight of the current process is greater than the weight of the subsequent process, if (b) the number of required members of Facility B is greater than the number of members of Facility A and the increase rate of Facility B is less than the increase rate of Facility A, the priority of Facility A is set higher than the priority of Facility B.

[0270] In addition, regardless of the magnitude relationship of the weights, if (a) the number of required members of Facility A is greater than the number of required members of Facility B and the increase rate of Facility A is greater than the increase rate of Facility B, the priority of Facility A is set higher than the priority of Facility B. The specific part 250, regardless of the magnitude relationship of the weights, if (b) the number of required members of Facility B is greater than the number of required members of Facility A and the increase rate of Facility B is greater than the increase rate of Facility A, the priority of Facility B is set higher than the priority of Facility A.

[0271] Note that, as in Embodiment 1, when not considering the weight and the increase rate, the specific part 250 may set the priority based only on the comparison result of the number of required members. Specifically, the specific part 250 sets the priority of Facility A higher than the priority of Facility B when (i) the number of required members of Facility A is greater than the number of required members of Facility B. Also, the specific part 250 sets the priority of Facility B higher than the priority of Facility A when (ii) the number of required members of Facility B is greater than the number of required members of Facility A. Further, the specific part 250 may not set the priority. When (i) the number of required members of Facility A is greater than the number of required members of Facility B, Facility A may be specified as the target member, and when (ii) the number of required members of Facility B is greater than the number of required members of Facility A, Facility B may be specified as the target facility.

[0272] (Display Example) Subsequently, a display example of the notification image by the restoration equipment notification system according to each of the above embodiments will be described with reference to FIGS. 30 and 31.

[0273] FIG. 30 is a diagram showing an example of a display screen by the recovery facility notification system 10 according to each embodiment. The display screen shown in FIG. 30 is displayed, for example, on the display unit 315 of the terminal device 300.

[0274] In FIG. 30, the names of three stopped facilities are arranged in descending order of priority from top to bottom. The difference in priority can be represented, for example, by the difference in the background color of the facility name. In FIG. 30, the difference in background color is represented by the difference in the shaded area within the frame. Here, an example is shown where the priorities of two facilities, "F0601" and "F0571", are the highest values.

[0275] The method of displaying the priority is not limited to the background color. The priority value itself may be displayed in association with the facility name. Alternatively, as in FIG. 30, the difference in priority may be represented by the difference in the shaded area within the frame. Alternatively, the difference in priority may be represented by the character color, character size, font, etc. of the facility name.

[0276] FIG. 31 is a diagram showing an example of the transition of the display screen by the recovery facility notification system 10 according to each embodiment. The display screen of FIG. 30 is set as the initial state. FIG. 31 shows an example of rearranging the display based on the priority of the stop cause.

[0277] The priority of the stop cause is the priority set so as to increase the productivity of the current process equipment, and is set based on the increment due to recovery. The priority of the facility is the priority set so as to increase the productivity of the subsequent process equipment, and is set based on the number of required members in the subsequent process equipment. Here, the priority of the stop cause and the priority of the facility are set respectively, and an example of changing the display according to the weight at the display stage is shown. In the example shown in FIG. 31, when the weight of the current process is heavier than the weight of the subsequent process, that is, an example of giving priority to the priority of the current process equipment is shown.

[0278] First, by receiving the low-priority stop factor A (stop code) at the high-priority facility F0571, this facility F0571 is arranged at the topmost position. Since facility F0601 has a higher priority than facility F0631, they are arranged in this order.

[0279] Next, by receiving the high-priority stop factor B at the low-priority facility F0631, facility F0631 is arranged at the topmost position. In FIG. 31, the high-priority stop factors are shown in bold. When receiving a high-priority stop factor, the terminal device 300 may vibrate.

[0280] Next, by receiving the high-priority stop factor B at the high-priority facility F0601, facility F0601 is arranged at the topmost position. Since facility F0631 has received a higher-priority stop factor B than facility F0571, they are arranged in this order.

[0281] Next, when the high-priority facility F0571 also receives the high-priority stop factor B, the priorities of all stop factors become the same, so the order is the priority order of the facilities. Specifically, it is the order in the initial state.

[0282] (Other embodiments) As described above, the recovery facility notification method and the like according to one or more aspects have been described based on the embodiments. However, the present disclosure is not limited to these embodiments.

[0283] For example, in the above embodiment, an example in which the recovery facility notification system 10 includes a terminal device 300 for each worker is shown, but it is not limited thereto. For example, the recovery facility notification system 10 may include a display device such as a large-screen monitor provided in the factory 1. The notification image from the recovery facility notification device 200 may be displayed on the display device and visible from within the factory 1.

[0284] Also, for example, in the notification image, although the names of all the current process facilities that are stopped are listed and displayed, it is not limited to this. Only the name of the target facility with the highest priority may be displayed. Alternatively, the names of a predetermined number of current process facilities may be displayed in descending order of priority. Also, instead of arranging them in order of priority, the priority may be displayed for each facility name.

[0285] Also, for example, the processing in the learning phase may be executed by a device different from the recovery facility notification system 10. That is, the recovery facility notification system 10 and the recovery facility notification device 200 may perform the processing in the usage phase using a learning model created by another device.

Also, the processor that executes the above program may be singular or plural. That is, centralized processing may be performed, or distributed processing may be performed.

[0289] Also, in the above embodiments, all or part of the components such as the control unit may be configured by dedicated hardware, or may be realized by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU (Central Processing Unit) or a processor reading and executing a software program recorded on a recording medium such as an HDD or a semiconductor memory.

[0290] Also, components such as the control unit may be configured by one or more electronic circuits. Each of the one or more electronic circuits may be a general-purpose circuit or a dedicated circuit.

[0291] One or more electronic circuits may include, for example, semiconductor devices, ICs (Integrated Circuits), or LSIs (Large Scale Integrations). The IC or LSI may be integrated on one chip or may be integrated on a plurality of chips. Here, it is called an IC or LSI, but the name may change depending on the degree of integration, and it may be called a system LSI, a VLSI (Very Large Scale Integration), or a ULSI (Ultra Large Scale Integration). Also, an FPGA (Field Programmable Gate Array) programmed after the manufacture of the LSI can be used for the same purpose.

[0292] Furthermore, the general or specific aspects of the present disclosure may be implemented as a system, apparatus, method, integrated circuit, or computer program. Alternatively, it may be implemented on a computer-readable non-transitory recording medium such as an optical disk, HDD, or semiconductor memory storing the computer program. It may also be implemented by any combination of a system, apparatus, method, integrated circuit, computer program, and recording medium.
