[0001] The present invention relates to a personnel allocation control device and a personnel allocation control method, and is suitable for application to a personnel allocation control device related to a technique for controlling the allocation of workers to each process of a production line, for example.

[0002] In recent years, as interest in environmental issues has increased, various measures have been tried to reduce the energy consumption when manufacturing products on a production line. Patent Document 1 discloses a technique for formulating a production plan that reduces environmental loads such as power consumption while complying with the required deadline, etc., even when mixed production of multiple product types is carried out.

[0003] Japanese Unexamined Patent Application Publication No. 2023 - 173567

[0004] Here, it is known that even for the same production line, the energy consumption on the production line varies depending on which worker is allocated to each process. Although the technique disclosed in Patent Document 1 aims to reduce environmental loads such as power consumption while complying with the required deadline, etc., from the perspective of production efficiency, the optimal workers are not arranged in each process of the production line, and it cannot be said that the energy consumption on the production line has been sufficiently minimized.

[0005] The present invention has been made in consideration of the above points, and intends to propose a personnel allocation control device and a personnel allocation control method that can suppress the energy consumption on the production line.

[0006] To solve these problems, the present invention includes: an energy calculation unit that calculates the energy consumption of each process in the manufacturing line for each combination of process and worker, and calculates the total energy consumption by summing the energy consumption of each process in the manufacturing line for all processes in the manufacturing line, based on operational information of each piece of equipment installed in each process of the manufacturing line to be analyzed, worker information relating to each worker in charge of each process of the manufacturing line, energy consumption information relating to the energy consumption of each piece of equipment, and product information relating to the products manufactured in the manufacturing line; an analysis unit that repeatedly changes the combination of process and worker in the manufacturing line and compares the total energy consumption calculated by the energy calculation unit to analyze the total energy consumption for each combination of process and worker in the manufacturing line; and a personnel allocation control unit that determines the combination of process and worker in the manufacturing line such that the total energy consumption for each combination of process and worker in the manufacturing line is below a predetermined threshold, based on the results of the analysis by the analysis unit.

[0007] Furthermore, the present invention includes an energy calculation step in which an energy calculation unit calculates the energy consumption of each process in the manufacturing line for each combination of process and worker, based on operational information of each piece of equipment installed in each process of the manufacturing line to be analyzed, worker information relating to each worker in charge of each process of the manufacturing line, energy consumption information relating to the energy consumption of each piece of equipment, and product information relating to the products manufactured in the manufacturing line, and also calculates the total energy consumption by summing the energy consumption of each process in the manufacturing line for all processes of the manufacturing line; an analysis step in which an analysis unit repeatedly changes the combination of each process and worker in the manufacturing line and compares the total energy consumption calculated by the energy calculation unit to analyze the total energy consumption for each combination of process and worker in the manufacturing line; and a personnel allocation control step in which a personnel allocation control unit determines the combination of each process and worker in the manufacturing line based on the results of the analysis by the analysis unit, such that the total energy consumption for each combination of process and worker in the manufacturing line is less than or equal to a predetermined threshold.

[0008] According to the present invention, energy consumption in the manufacturing line can be reduced.

[0010] Hereinafter, this embodiment of the present invention will be described in detail with reference to the drawings. Figure 1 is a system configuration diagram showing an example of the configuration of the personnel allocation control device 100 according to this embodiment. The personnel allocation control device 100 has the function of controlling the allocation of workers who are to be in charge of each piece of equipment in each process of a product manufacturing line. Each product includes at least one semi-finished product. In this embodiment, the semi-finished product is also referred to as a part.

[0011] The personnel allocation control device 100 is, for example, a computer. The personnel allocation control device 100 includes a memory 1, a CPU (Central Processing Unit) 2, an input receiving unit 3, a storage device 4, an input / output interface (abbreviated as "I / F") 5, a network I / F (NW I / F shown in the figure) 6, and a bus 9. These memory 1, CPU 2, storage device 4, I / F 5, and network I / F 6 are connected to each other via the bus 9 and can exchange data and instructions with each other. For example, each software block operates using the memory 1 under the control of the CPU 2, but in the following description, for the sake of simplicity in the illustrations, the CPU 2 is shown as having each of these software blocks.

[0012] Memory 1 has a database 20. Database 20 contains operational information 21, worker information 22, energy consumption information 23, product information 24, and personnel allocation information 25. Database 20 may also manage other information. The personnel allocation control device 100 manages the operational information 21, worker information 22, energy consumption information 23, product information 24, and personnel allocation information 25 in association with each other. This operational information 21, worker information 22, energy consumption information 23, and product information 24 may be input, for example, via an input / output I / F 5 as an example of an input unit.

[0013] Operational information 21 is information showing the operating status of each piece of equipment installed at each process of the manufacturing line being analyzed. Worker information 22 is information about each worker in charge of each process of the manufacturing line. Energy consumption information 23 is information about the energy consumption of each piece of equipment obtained based on the operational information 21. Product information 24 is product information about the products manufactured on the manufacturing line.

[0014] Personnel allocation information 25 is information for managing the allocation of workers who should be in charge of each piece of equipment in each process of a product's manufacturing line.

[0015] The CPU 2 has, for example, an energy calculation unit 11, an analysis unit 12, and a personnel allocation control unit 13 as functions of each software block. Note that the functions of each software block are not limited to the configuration of this embodiment, and any one of the energy calculation unit 11, analysis unit 12, or personnel allocation control unit 13 may also perform the functions of the other blocks.

[0016] The energy calculation unit 11 calculates the energy consumption of each process in the manufacturing line for each combination of each process in the manufacturing line and each worker, based on the operating information 21 of each piece of equipment installed in each process of the manufacturing line under analysis, worker information 22 concerning each worker in charge of each process in the manufacturing line, energy consumption information 23 concerning the energy consumption of each piece of equipment obtained based on the operating information 21, for example, and product information 24 concerning the products manufactured in the manufacturing line.

[0017] These operational information 21, worker information 22, energy consumption information 23, and product information 24 may be in a form that is input and stored in memory 1, or they may be in a form that is stored in memory 1 in advance.

[0018] Furthermore, the energy calculation unit 11 calculates the total energy consumption by summing up the energy consumption of each process in the manufacturing line for all processes in the manufacturing line. In other words, the total energy consumption represents the total energy consumption in a given manufacturing line.

[0019] The analysis unit 12 analyzes the total energy consumption for each combination of process and worker in the manufacturing line by repeatedly changing the combination of each process and worker in the manufacturing line and comparing the total energy consumption calculated by the energy calculation unit 11. In other words, the total energy consumption referred to here is, for example, the sum of the energy consumption for all processes in the manufacturing line.

[0020] Based on the results of the analysis by the analysis unit 12, the personnel allocation control unit 13 determines the combination of each process and worker in the manufacturing line so that the total energy consumption for each combination of process and worker in the manufacturing line is below a predetermined threshold.

[0021] Preferably, the personnel allocation control unit 13 determines the combination of each process in the manufacturing line and each worker so as to minimize the total energy consumption for each combination of each process in the manufacturing line and each worker.

[0022] The energy calculation unit 11 described above allocates the amount of electricity consumed per unit time by each piece of equipment installed in each process of the manufacturing line to each product, and calculates the amount of energy consumed in each process of the manufacturing line for each combination of each process of the manufacturing line and each worker.

[0023] The database 20 manages product error rates as part of the product information, for example, the percentage of products that become defective as a result of the work performed by each worker in charge of each process on the manufacturing line. The personnel allocation control unit 13 refers to the database 20 and, taking into account the product error rates of each worker in charge of each process on the manufacturing line, determines the combination of each process on the manufacturing line and each worker.

[0024] The personnel allocation control device 100 includes a worker input screen, which is an example of a worker input unit for inputting specific workers who should be permanently assigned to specific processes on the manufacturing line, as part of the worker information described above. A specific example of the worker input screen will be described later.

[0025] Figure 2 shows an example of data collected at each step of the manufacturing line in this embodiment. In this embodiment, a manufacturing line is described as including, as an example of the steps described above, a first operation as the first step P1, a second operation as the second step P2, and a first inspection as the third step P3.

[0026] The first task, as the first process P1, indicates, for example, that worker A is manufacturing a product based on external information, using first equipment from among several types of equipment, starting from a first part and following a first procedure. Here, the product is manufactured from a part such as the first part, but this embodiment is not limited to such a part, and the product may be manufactured from a material such as the first substance. Furthermore, in this embodiment, the task such as the first task includes a procedure such as the first procedure described above, but it is not limited to this, and for example, it does not include a procedure.

[0027] The second operation, as the second process P2, indicates, for example, that worker B is manufacturing a product based on external information, following a second procedure, using the second piece of equipment from among several types of equipment, from the product from the first process P1 and a second component (for example, a second substance) as described above.

[0028] The first inspection, as the third process P3, indicates, for example, that worker C is inspecting the product from the second process P2 described above using a third piece of equipment from among several types of equipment, in accordance with the third procedure and based on external information.

[0029] Figure 3 shows an example of manufacturing line management information 29 when the data shown in Figure 2 is collected. In the first operation as the first process P1 described above, for example, worker A manufactures a product based on external information α by using the first equipment from among several types of equipment to produce a product from a first part according to the first procedure, and it is shown that the energy consumption is 60 [kWh].

[0030] In the second operation, which is the second process P2 described above, for example, worker B uses the second piece of equipment from among several types of equipment to manufacture a product from the product from the first process P1 described above and the second part, following the second procedure and based on external information β, thereby indicating, for example, that the energy consumption is 120 [kWh].

[0031] In the first inspection, which is the third step P3 described above, for example, worker C uses the third piece of equipment from among several types of equipment to inspect the product from the second step P2 described above according to the third procedure, based on external information γ, thereby indicating, for example, that the energy consumption is 60 [kWh].

[0032] Figure 4 shows an example of the operational information 21 shown in Figure 1. The operational information 21 manages the production line name, which represents the name of the production line; the process name, which represents the name of each process; the equipment name, which represents the name of each piece of equipment; the operating time, which indicates the time when each piece of equipment was operated; the production serial number of the product manufactured by each piece of equipment in each process; and the energy consumption [kWh] by each piece of equipment in each process. For example, the operational information 21 shows the operating time and energy consumption of each piece of equipment in each process of the "door manufacturing" production line.

[0033] Figure 5 shows an example of the worker information 22 shown in Figure 1. The worker information 22 manages, for example, the work name which represents the worker's name, the process name which represents the name of the process the worker is in charge of, and the time the worker worked on that process. The worker information 22 includes, for example, a record for each worker.

[0034] Figure 6 shows an example of the energy consumption information 23 shown in Figure 1. The energy consumption information 23 manages, for example, the process name representing the name of each process, the equipment name representing the name of each piece of equipment, the energy consumption time indicating the time when energy was consumed, and the amount of energy consumed by each piece of equipment in each process.

[0035] The illustrated example shows, for instance, the energy consumption from 9:00 to 10:00 during the first to third processes. For the sake of simplicity, the illustrated example omits examples of energy consumption after 10:00.

[0036] Figure 7 shows an example of the product information 24 shown in Figure 1. The product information 24 manages, for example, the product's serial number, product name, part name, and the number of units manufactured. The product's serial number is identification information used to distinguish between multiple products. The product name represents the name of the product. The part name represents the name of the part (semi-finished product) that makes up the product. The number of units manufactured indicates the number of identical products manufactured on the production line.

[0037] The personnel allocation control device 100 according to this embodiment has the configuration described above. Next, an example of a personnel allocation control method using the personnel allocation control device 100 will be described.

[0038] Figure 8 is a flowchart showing an example of the main processing of the personnel allocation control method according to this embodiment. In step S1, the energy calculation unit 11 performs energy calculation processing. In the energy calculation processing, the energy calculation unit 11 calculates the energy consumption of each process in the manufacturing line for each combination of each process in the manufacturing line and each worker, based on the operating information 21 of each piece of equipment installed in each process of the manufacturing line to be analyzed, worker information 22 regarding each worker in charge of each process in the manufacturing line, energy consumption information 23 regarding the energy consumption of each piece of equipment obtained based on the operating information 21, and product information 24 regarding the products manufactured in the manufacturing line. It also calculates the total energy consumption by summing the energy consumption of each process in the manufacturing line for all processes in the manufacturing line. Details of step S1 will be described later.

[0039] In step S2, the analysis unit 12 analyzes the total energy consumption for each combination of process and worker on the manufacturing line by repeatedly comparing the total energy consumption calculated by the energy calculation unit 11 with, for example, all processes on the manufacturing line.

[0040] In step S3, the personnel allocation control unit 13 determines the combination of each process and worker in the manufacturing line based on the results of the analysis by the analysis unit 12, such that the total energy consumption for each combination of each process and worker in the manufacturing line is below a predetermined threshold.

[0041] Figures 9 to 12 show examples of temporary files created temporarily during the energy calculation process shown in Figure 8. The information shown in Figures 9 to 12 is created by the energy calculation unit 11. Note that while only the time is shown in Figures 9 to 12, the date may also be included.

[0042] The energy calculation unit 11 extracts the operation time when the equipment name of a certain process in the manufacturing line of the operation information 21 shown in FIG. 4 corresponds to "the first equipment" for the operator name "Operator A" in the operator information 22 shown in FIG. 5, calculates the power consumption for each production number and operator, and creates a temporary file shown in FIG. 9. The temporary file shown in FIG. 9 includes the operation time, production number, operator, and energy consumption.

[0043] The energy calculation unit 11 determines the combination of each process of the manufacturing line and each operator in consideration of the error rate of the products by each operator in charge of each process of the manufacturing line. Specifically, the energy calculation unit 11 considers the error rate "0.1" of the products by Operator A as an example of an operator for the production number "10000" shown in FIG. 10, multiplies, for example, the energy consumption "1" by (1 + 0.1), and sets the normal energy consumption regarding the production number "10000" of the products manufactured by Operator A at the operation time of 9:00 as 1.1 [kWh] as shown in FIG. 11.

[0044] Regarding the above points, the energy calculation unit 11 similarly calculates the normal energy consumption as shown in FIG. 12 for the operator name "Operator B" and the like. Note that the calculation for Operator B is substantially the same except for the difference in the error rate value, so the explanation is omitted. Here, the normal energy consumption considering the error rate is calculated, but it is not limited to this, and the above normalization may not be performed.

[0045] The energy calculation unit 11 summarizes the normal energy consumption of each equipment in each process of the manufacturing line based on, for example, the normal energy consumption and the like shown in FIGS. 11 and 12, and calculates the total energy consumption of the operators for each operation time, production number, and process of the manufacturing line as shown in FIG. 13. That is, the energy calculation unit 11 calculates the total energy consumption obtained by summing up the energy consumption of each process of the manufacturing line for all the processes of the manufacturing line.

[0046] The analysis unit 12 repeatedly changes the combination of each process on the production line and each worker, and analyzes the total energy consumption amounts calculated by the energy calculation unit 11 by comparing them with each other for, for example, all the processes on the production line, to analyze the total energy consumption amount for each combination of each process on the production line and each worker. The total energy consumption amount is the average total energy consumption amount.

[0047] FIG. 14 is a diagram showing an example of the total energy consumption amount for each combination of each process on the production line and each worker. The illustrated total energy consumption amount is the average total energy consumption amount. Each of the first process, the second process, and the third process is assumed, as an example, to be handled by worker A to worker C, respectively.

[0048] For example, the analysis unit 12 analyzes that in the combination of each process on the production line and each worker for the product with the production number “10000” shown in the figure, when worker A is in charge of the first process, the average total energy consumption amount tends to be smaller than when worker B or worker C is in charge of the first process.

[0049] Next, for example, the analysis unit 12 analyzes that in the combination of each process on the production line and each worker for the product with the production number “10000” shown in the figure, when worker C is in charge of the second process, the average total energy consumption amount tends to be smaller than when worker A or worker B is in charge of the second process.

[0050] Furthermore, for example, the analysis unit 12 analyzes that in the combination of each process on the production line and each worker for the product with the production number “10000” shown in the figure, when worker B is in charge of the third process, the average total energy consumption amount tends to be smaller than when worker A or worker C is in charge of the third process.

[0051] From the above, for example, the analysis unit 12 analyzes that in the combination of each process on the production line and each worker for the product with the production number “10000” shown in the figure, the case where worker A is in charge of the first process, worker C is in charge of the second process, and worker B is in charge of the third process tends to have the smallest average total energy consumption amount.

[0052] Based on the results of the analysis by the analysis unit 12, the personnel allocation control unit 13 determines the combination of each process and worker in the manufacturing line such that the total energy consumption for each combination of process and worker in the manufacturing line is below a predetermined threshold, preferably to the minimum.

[0053] Figures 15 and 16 show examples of worker input screens for specifying the workers responsible for each piece of equipment in the first process. Note that the illustration of the calculated total energy consumption is omitted in the examples shown.

[0054] In the worker input screen shown in Figure 15, one piece of equipment can be selected from "First Equipment of the First Process," "Second Equipment of the First Process," and "Third Equipment of the First Process" using radio buttons. In the worker input screen shown, worker A is selected for the first equipment of the first process.

[0055] In the worker input screen shown in Figure 16, worker A is assigned to the first piece of equipment in the first process, for example. In this way, the total energy consumption can be calculated as described above, with worker A fixed to the first piece of equipment in the first process.

[0056] Figures 17 and 18 show examples of screens for specifying the workers and fixed equipment responsible for each piece of equipment in the first process, respectively. Note that the illustration of the calculated total energy consumption is omitted in the examples shown.

[0057] The screen shown in Figure 17 is similar to the screen shown in Figure 15 described above, but a drop-down list for specifying fixed equipment is provided on the right side. This drop-down list allows, for example, in the first process, to select any of the equipment from the first to the third equipment.

[0058] Therefore, in the illustrated example, one piece of equipment can be selected from among "First Equipment of the First Process," "Second Equipment of the First Process," and "Third Equipment of the First Process" using radio buttons. Furthermore, worker A is assigned to the first equipment of the first process, and the second equipment is assigned to worker A via a dropdown list.

[0059] In the next screen shown in Figure 18, for example, worker A is assigned to the first equipment in the first process. In this way, the total energy consumption can be calculated as described above, with worker A fixed to the first equipment in the first process.

[0060] As described above, the personnel allocation control device 100 according to this embodiment includes: an energy calculation unit 11 that calculates the energy consumption of each process in the manufacturing line for each combination of process and worker in the manufacturing line, and calculates the total energy consumption by summing the energy consumption of each process in the manufacturing line for all processes in the manufacturing line, based on operational information 21 of each piece of equipment installed in each process of the manufacturing line to be analyzed, worker information 22 of each worker in charge of each process of the manufacturing line, energy consumption information 23 of the energy consumption of each piece of equipment, and product information 24 of the products manufactured in the manufacturing line; an analysis unit 12 that repeatedly changes the combination of process and worker in the manufacturing line and compares the total energy consumption (for example, for all processes in the manufacturing line) calculated by the energy calculation unit 11 to analyze the total energy consumption for each combination of process and worker in the manufacturing line; and a personnel allocation control unit 13 that determines the combination of process and worker in the manufacturing line so that the total energy consumption for each combination of process and worker in the manufacturing line is less than or equal to a predetermined threshold, based on the results of the analysis by the analysis unit 12.

[0061] In this way, the combination of each process and worker on the manufacturing line is determined so that the total energy consumption for each combination of process and worker on the manufacturing line is below a predetermined threshold, thereby suppressing the energy consumption on the manufacturing line to be below a predetermined threshold.

[0062] In this embodiment, the personnel allocation control unit 13 determines the combination of each process and worker on the manufacturing line so as to minimize the total energy consumption for each combination. In this way, the combination of each process and worker on the manufacturing line is determined so as to minimize the total energy consumption for each combination, thereby minimizing energy consumption on the manufacturing line.

[0063] In this embodiment, the energy calculation unit 11 allocates the power consumption per unit time of each piece of equipment installed in each process of the manufacturing line to each product, and calculates the energy consumption of each process of the manufacturing line for each combination of process and worker. In this way, the combination of each process and worker of the manufacturing line is determined based on the energy consumption of each process allocated to each product, so that energy consumption on the manufacturing line can be suppressed while taking into account the energy consumption of each product.

[0064] The personnel allocation control device 100 according to this embodiment includes a worker input unit for inputting specific workers who should be permanently assigned to specific processes on the manufacturing line, as part of the worker information. In this way, by assigning, for example, specific workers who are efficient at performing that particular process to a specific process on the manufacturing line, energy consumption on the manufacturing line can be reduced.

[0065] The personnel allocation control device 100 according to this embodiment includes a database that associates operational information 21, worker information 22, energy consumption information 23, and product information 24. In this way, energy consumption on the manufacturing line can be suppressed based on the associated operational information 21, worker information 22, energy consumption information 23, and product information 24.

[0066] In this embodiment, the database 20 manages the product error rate by each worker in charge of each process in the manufacturing line as part of the product information 24, and the personnel allocation control unit 13 refers to the database 20 and determines the combination of each process in the manufacturing line and each worker, taking into account the product error rate by each worker in charge of each process in the manufacturing line. In this way, it becomes possible to assign each worker to each process while suppressing the product error rate, and thus it is possible to reduce energy consumption in the manufacturing line while keeping the product error rate low.

[0067] The personnel allocation control device 100 according to this embodiment includes an input / output I / F 5 as an example of an input unit for inputting operational information 21, worker information 22, energy consumption information 23, and product information 24. In this way, energy consumption on the manufacturing line can be suppressed based on the operational information 21, worker information 22, energy consumption information 23, and product information 24 input from an external source.
