Description

【Technical Field】 【0001】 The present invention relates to a production management device, a production management method, and a production management program. 【Background Art】 【0002】 Conventionally, there is a processing man-hour estimation device including design data extraction means for extracting the number of parts for each classification type, the number of occurrences of work units independent of parts, and common work units independent of models from the design data of a target product, and standard man-hour calculation means for obtaining the standard man-hours required for manufacturing the target product by calculating the product of the standard man-hour per work unit of each work unit collected in advance and the number of occurrences of the work unit (see Patent Document 1, etc.). 【0003】 Conventional processing man-hour estimation devices, for example, for products similar to the target product, obtain the standard man-hours, obtain the actual man-hours required for actual production, and obtain the actual situation coefficient by dividing the actual man-hours of the similar product by the standard man-hours, and obtain the processing man-hours of the target product by multiplying the standard man-hours of the target product by the actual situation coefficient. 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2006-127012 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 However, actual man-hours are influenced by various environmental factors that differ for each task, such as the number of workers in manual manufacturing processes or the number of inventory items to be processed during setup. In other words, conventional man-hour estimation devices simply multiply the standard man-hours of the target product by an actual coefficient obtained by dividing the actual man-hours of a product by the standard man-hours. This does not take into account environmental factors such as the number of workers in each manufacturing process or inventory status, resulting in poor accuracy in man-hour estimation. 【0006】 One aspect of the present invention is a production management device, a production management method, and a production management program that can improve the accuracy of work-hour estimation. [Means for solving the problem] 【0007】 A production management device according to one aspect of the present invention is configured to perform: a provisional man-hour acquisition process for acquiring provisional man-hours for parts to be processed; an actual information acquisition process for acquiring actual information including actual man-hours for one or more parts identical to the parts to be processed; a history acquisition process for acquiring the inflow and outflow history of work-in-progress inventory identical to the parts to be processed; a correction condition calculation process for calculating correction conditions for the provisional man-hours from the actual man-hours and the inflow and outflow history; and a man-hour correction process for correcting the provisional man-hours based on the correction conditions, and is configured to use the corrected provisional man-hours as the man-hours for the parts to be processed. 【0008】 A production management method according to one aspect of the present invention comprises: a provisional man-hour acquisition step of acquiring provisional man-hours for a part to be processed; an actual information acquisition step of acquiring actual information including actual man-hours for one or more parts identical to the part to be processed; a history acquisition step of acquiring the inflow and outflow history of work-in-progress inventory identical to the part to be processed; a correction condition calculation step of calculating correction conditions for the provisional man-hours from the actual man-hours and the inflow and outflow history; and a man-hour correction step of correcting the provisional man-hours based on the correction conditions, wherein the corrected provisional man-hours are used as the man-hours for the part to be processed. 【0009】 A production management program according to one aspect of the present invention causes a production management device to execute the following processes: a provisional man-hour acquisition process to acquire provisional man-hours for a part to be processed; an actual information acquisition process to acquire actual information including actual man-hours for one or more parts that are the same as the part to be processed; a history acquisition process to acquire the inflow and outflow history of work-in-progress inventory of the same part that is the same as the part to be processed; a correction condition calculation process to calculate correction conditions for the provisional man-hours from the actual man-hours and the inflow and outflow history; and a man-hour correction process to correct the provisional man-hours based on the correction conditions, and uses the corrected provisional man-hours as the man-hours for the part to be processed. 【0010】 According to one aspect of the present invention, a production management device, a production management method, and a production management program are used to calculate correction conditions for provisional setup man-hours from actual setup man-hours and inventory history, and to correct provisional setup man-hours based on these correction conditions, thereby improving the accuracy of man-hour estimation. [Effects of the Invention] 【0011】 According to one aspect of the present invention, the production management apparatus, production management method, and production management program can improve the accuracy of work hour estimation.

[Modes for carrying out the invention] 【0013】 The best embodiment for carrying out the present invention will be described below with reference to the drawings. Note that the following embodiments are not intended to limit the invention as described in each claim, and not all combinations of features described in the embodiments are necessarily essential to the solution of the invention. 【0014】 [Overall configuration of the manufacturing support system according to this embodiment] Figure 1 is a schematic diagram showing a manufacturing support system according to an embodiment of the present invention. First, with reference to Figure 1, a manufacturing support system 1 according to an embodiment of the present invention will be outlined. The manufacturing support system 1 according to this embodiment is a manufacturing support system that manages the schedule and progress of the manufacturing process of a product containing one or more parts. The manufacturing support system 1, in general terms, comprises a production management device 10, a server 50, and a processing machine 70, as shown in Figure 1. These devices are connected to each other in a manner that allows them to communicate with one another. 【0015】 The product manufacturing process includes, for example, a blanking process in which a single sheet of standard-length metal (hereinafter referred to as a sheet in this embodiment) is cut into any shape, a sorting process in which work-in-progress is sorted on the sheet after the blanking process, a secondary process, an assembly process, an inspection process, and other processes until the product is completed. The secondary process includes, for example, bending, painting, deburring, etc. The assembly process includes welding, screwing, etc. 【0016】 In this embodiment, work-in-progress refers to products and parts that are in the manufacturing process but have not yet been completed as finished goods. In this embodiment, a product refers to a product that has gone through all manufacturing processes in the factory and is ready for delivery to a customer. Furthermore, in this embodiment, a part refers to a component of a product. 【0017】 Furthermore, the manufacturing support system 1 further includes one or more performance registration terminals 90 used in each work area of ​​the process in which workers perform processing, regardless of the processing machine 70. The production management device 10, server 50, processing machine 70, and performance registration terminals 90 are connected to each other so as to be able to communicate with one another via a private network such as a local network or intranet. When connected by wireless communication, the manufacturing support system 1 may further include one or more access points AP. 【0018】 Figure 2 is a functional block diagram showing the production control device of this embodiment. The production management device 10 is an electronic computer such as a desktop personal computer, laptop computer, or tablet terminal, and as shown in Figure 2, it includes an input unit 110, a display unit 120, a control unit 130, and a storage unit 140. In general, the production management device 10 manages order information, product information, manufacturing process information for products and parts, and progress information for each manufacturing process. The production management device 10 also handles the ordering of product production. 【0019】 Furthermore, the production management device 10 creates a production schedule for a series of manufacturing processes for each product, as well as a process schedule for each manufacturing process, and manages the production schedule, process schedule, and workload for each process. In this embodiment, the production management device 10 calculates the man-hours for each manufacturing process of the parts included in each product, and manages the process schedule and workload for each manufacturing process by adding the man-hours for the product and parts to the daily process schedule for each process. 【0020】 In this embodiment, man-hours refer to the time required for the production (processing) of products and parts. Man-hours include setup man-hours and processing man-hours, and are expressed as the sum of setup man-hours and processing man-hours. Setup man-hours refer to the man-hours for tasks that are performed only once, regardless of the number of work-in-progress items to be processed (created) in that manufacturing process, such as transporting work-in-progress items from the storage area to the workshop, supplying sheets to the blanking machine 70a (described later), or setting the molds in the bending machine of the secondary processing machine 70b (described later). 【0021】 Furthermore, processing man-hours are the man-hours required for each processing operation, and are calculated by multiplying them by the number of work-in-progress items (number produced). For example, in the blanking process, if multiple identical parts (work-in-progress items) are produced by processing a single sheet, the processing man-hours are calculated by multiplying the time it takes to cut out one part by the number produced. 【0022】 The input unit 110 is comprised of input devices such as a keyboard, mouse, touchpad, and joystick. By operating the input unit 110, in addition to the information input functions normally required in the production management device 10, operations such as creating process schedules and correcting man-hours can be performed. With this configuration, the production management device 10 can perform operations such as creating process schedules and correcting man-hours manually via the input unit 110. 【0023】 The display unit 120 has a display as a display device, and in addition to the screen display functions normally required in the production management device 10, it displays, for example, a process schedule screen. The display unit 120 may also be configured as a touch panel (Touch screen) that has the functions of the input unit 110. If the display unit 120 is configured as a touch panel, the user can input various information, such as instructions for correcting man-hours, to the production management device 10 by operating the display unit 120. 【0024】 Furthermore, the configuration of the input unit 110 and the display unit 120 is not limited to the configuration described above. Any configuration with equivalent functionality (for example, a remotely accessible display means or input means) can be used instead of the input unit 110 and the display unit 120. 【0025】 The control unit 130 is composed of, for example, an integrated computing device having a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit). As shown in Figure 2, the control unit 130 includes a provisional man-hour acquisition unit 131, an actual information acquisition unit 133, an inventory information acquisition unit 135, and a man-hour correction unit 137. 【0026】 Figure 4 is a flowchart showing an example of a process performed by the control unit of the production management device in this embodiment. As shown in Figure 4, the provisional man-hour acquisition unit 131 is configured to execute a provisional man-hour acquisition process (S1 in Figure 4) to acquire the provisional setup man-hours PMa of the part to be processed. Specifically, the provisional man-hour acquisition unit 131 acquires the provisional man-hours PM for each manufacturing process of the part to be processed from the standard man-hour database 51 of the server 50, which will be described later. In this embodiment, the provisional man-hours PM are the provisional man-hours for each manufacturing process of the part to be processed, and include the provisional setup man-hours PMa and the provisional processing man-hours PMb. The provisional setup man-hours PMa are the provisional man-hours for the setup work. 【0027】 The provisional setup man-hours PMa acquired by the provisional man-hour acquisition unit 131 may be the standard setup man-hours 52a of the part to be processed, or the man-hours obtained by correcting the standard setup man-hours 52a of the part to be processed based on the actual setup man-hours 55a (corrected standard setup man-hours 52a', described later). Furthermore, the provisional setup man-hours PMa acquired by the provisional man-hour acquisition unit 131 may be the man-hours obtained by correcting the standard setup man-hours 52a of the part to be processed based on the actual performance information of the worker scheduled to be in charge of the setup work for the part to be processed (corrected standard setup man-hours 52a'). 【0028】 Similarly, the provisional processing man-hours PMb acquired by the provisional man-hour acquisition unit 131 may be the standard processing man-hours 52b of the part to be processed, or the man-hours obtained by correcting the standard processing man-hours 52b of the part to be processed based on the actual processing man-hours 55b (corrected standard processing man-hours 52b', described later). Furthermore, the provisional processing man-hours PMb acquired by the provisional man-hour acquisition unit 131 may be the man-hours obtained by correcting the standard processing man-hours 52b of the part to be processed based on the actual performance information of the workers scheduled to be in charge of processing the part to be processed (corrected standard processing man-hours 52b'). 【0029】 In addition, during the provisional man-hour acquisition process, the provisional man-hour acquisition unit 131 only needs to acquire the provisional setup man-hours PMa, and does not need to acquire the provisional machining man-hours PMb. 【0030】 As shown in Figure 4, the performance information acquisition unit 133 is configured to perform a performance information acquisition process (S2 in Figure 4) that acquires performance information 54 including one or more actual setup man-hours 55a for the same part as the part to be processed. Specifically, the performance information acquisition unit 133 acquires performance information 54 from the processing performance database 53 of the server 50, which will be described later. In this embodiment, the performance information 54 acquired by the performance information acquisition unit 133 includes actual man-hours 55 for each manufacturing process of the same part as the part to be processed. 【0031】 In this embodiment, the actual man-hours 55 refer to the actual man-hours recorded in the past for that manufacturing process. The actual man-hours 55 include the actual setup man-hours 55a and the actual processing man-hours 55b. 【0032】 Furthermore, the performance information 54 acquired by the performance information acquisition unit 133 includes at least the work days for setup work and processing for every 55 actual man-hours, and the number of parts produced that are the same as the planned parts for processing related to the setup work and processing for every 55 actual man-hours. In addition, the performance information 54 acquired by the performance information acquisition unit 133 includes worker information of the workers in charge of each manufacturing process. 【0033】 In this embodiment, "including at least the work day" means including at least the date on which the work was performed, and may also include more detailed time information in addition to the date on which the work was performed. 【0034】 In addition, during the process of acquiring performance information, the performance information 54 only needs to include at least the actual setup man-hours 55a, and does not need to include the actual processing man-hours 55b. 【0035】 Furthermore, the performance information acquisition unit 133 is configured to acquire performance information 54 necessary for the man-hour correction unit 137 to correct the standard setup man-hours 52a from the processing performance database 53 of the server 50. 【0036】 As shown in Figure 4, the inventory information acquisition unit 135 is configured to execute a history acquisition process (S3 in Figure 4) that acquires the inflow and outflow history 57 of work-in-progress inventory of the same part as the part to be processed. The inflow and outflow history 57 acquired by the inventory information acquisition unit 135 includes at least the inflow and outflow dates 57b of the work-in-progress inventory and the number of work-in-progress inventory items (work-in-progress inventory quantity 57a) for each inflow and outflow date 57b. The inflow and outflow history 57 acquired by the inventory information acquisition unit 135 also includes the number of inflows and outflows of work-in-progress inventory items 57c. 【0037】 In this embodiment, work-in-progress inventory is the inventory of work-in-progress items that are stored between the completion of the previous manufacturing process and the start of the next manufacturing process. Also in this embodiment, receiving means that the work-in-progress items that have been completed in the previous manufacturing process have been brought into the storage area, and issuing means that the work-in-progress items have been removed from that storage area for the next manufacturing process. 【0038】 Furthermore, the storage area is not limited to storage locations intended for inventory storage, such as inventory shelves or automated warehouses; it may also be a simple space in each work area for temporarily storing work-in-progress. 【0039】 In this embodiment, "including at least the date of receipt and shipment" means including at least the date on which the goods were received or shipped, and may also include more detailed time information in addition to the date on which the goods were received or shipped. 【0040】 The man-hour correction unit 137 is configured to correct the standard setup man-hours 52a of the part to be processed based on the actual setup man-hours 55a. Specifically, the man-hour correction unit 137 is configured to calculate the percentage increase or decrease of man-hours relative to the standard setup man-hours 52a for each actual setup man-hour, and to correct the standard setup man-hours 52a based on the average value of the percentage increase or decrease. The man-hour correction unit 137 saves the corrected standard setup man-hours 52a as corrected standard setup man-hours 52a' in the standard man-hour database 51 of the server 50. 【0041】 Figure 5 is a schematic diagram showing an example of standard setup man-hours in this embodiment. Figure 6 is a schematic diagram showing an example of actual setup man-hours in this embodiment. Figure 7 is a diagram showing an example of the correction of standard setup man-hours by the man-hour correction unit in this embodiment. For example, as shown in Figure 5, there is a part "A001" with a standard setup man-hour 52a for the welding process of 100 seconds. There are four actual performance data 54 for part "A001", as shown in Figure 6. The actual setup man-hours 55a for the welding process in each of the performance data 54 are 80 seconds, 120 seconds, 130 seconds, and 90 seconds, respectively, from top to bottom. The man-hour correction unit 137 calculates the percentage increase or decrease in man-hours for each actual setup man-hour 55a relative to the standard setup man-hour 52a, as shown in Figure 7. 【0042】 Figure 8 shows an example of the correction of standard setup man-hours by the man-hour correction unit of this embodiment. The percentage increase or decrease in man-hours for each actual setup man-hour 55a relative to the standard setup man-hour 52a is -20%, +20%, +30%, and -10% from top to bottom. The average of these percentage increase or decrease in man-hours is +5%, and as shown in Figure 8, the man-hour correction unit 137 uses this average value +5% as the correction value for the standard setup man-hour 52a of the welding process for part "A001", and corrects the standard setup man-hour 52a. The corrected standard setup man-hour 52a (corrected standard setup man-hour 52a') for the welding process of part "A001" becomes 105 seconds. 【0043】 Similarly, the man-hour correction unit 137 is configured to correct the standard processing man-hours 52b of the part to be processed based on the actual processing man-hours 55b. Specifically, the man-hour correction unit 137 is configured to calculate the rate of increase or decrease of man-hours relative to the standard processing man-hours 52b for each actual processing man-hour 55b, and to correct the standard processing man-hours 52b based on the average value of the rate of increase or decrease. The man-hour correction unit 137 saves the corrected standard processing man-hours 52b as corrected standard processing man-hours 52b' in the standard man-hour database 51 of the server 50. 【0044】 Figure 9 is a schematic diagram showing an example of standard processing man-hours in this embodiment. Figure 10 is a schematic diagram showing an example of actual processing man-hours in this embodiment. For example, as shown in Figure 9, there is a part "A001" with a standard welding process time 52b of 40 seconds / piece. There are four actual performance records 54 for part "A001", as shown in Figure 10. The actual welding process time 55b for each of the performance records 54 are, from top to bottom, 360 seconds, 800 seconds, 460 seconds, and 640 seconds. Also, the number of parts "A001" produced for each of the performance records 54 are, from top to bottom, 10, 20, 10, and 20. 【0045】 Figure 11 shows an example of the correction of standard machining man-hours by the man-hour correction unit of this embodiment. As shown in Figure 11, the man-hour correction unit 137 calculates the percentage increase or decrease in man-hours for each actual processing man-hour 55b relative to the standard processing man-hour 52b. Specifically, the man-hour correction unit 137 first divides each actual processing man-hour 55b for part "A001" by the number of parts "A001" produced to calculate the actual processing man-hour 55b per part "A001". The actual processing man-hours 55b per part "A001" for each actual information 54 are, from top to bottom, 36 seconds / piece, 40 seconds / piece, 46 seconds / piece, and 32 seconds / piece. 【0046】 Figure 12 shows an example of the correction of standard machining man-hours by the man-hour correction unit of this embodiment. The percentage increase or decrease in the number of processing steps 55b for each actual processing step 55b relative to the standard processing step 52b is -10%, ±0%, +15%, and -20%, respectively. The average of these percentage increase or decrease in processing steps is -3.75%, and as shown in Figure 12, the processing step correction unit 137 uses this average value of -3.75% as the correction value for the standard processing step 52b of the welding process for part "A001", and corrects the standard processing step 52b. The corrected standard processing step 52b (corrected standard processing step 52b') for the welding process of part "A001" becomes 38.5 seconds / piece. 【0047】 Furthermore, the man-hour correction unit 137 is configured to correct the standard setup man-hours 52a of the part to be processed based on the individual worker performance information of the worker scheduled to be in charge of the setup work for the part to be processed. The individual worker performance information includes the actual setup man-hours 55a of parts other than the part to be processed for which the worker was in charge of the setup work. Specifically, the individual worker performance information is extracted from multiple performance information 54, and only the performance information 54 in which the worker information included in the performance information 54 is that of the worker scheduled to be in charge of the setup work for the part to be processed. 【0048】 Figures 13 and 14 show an example of the standard setup man-hours in this embodiment. For example, as shown in Figure 13, there is a new part "G001" for which there is no performance information 54. The standard setup man-hour 52a for the welding process of part "G001" is 120 seconds. Also, as shown in Figure 14, there are parts "A001" to "F001" which are different from part "G001". The standard setup man-hours 52a for the welding process of parts "A001" to "F001" are 100 seconds, 100 seconds, 120 seconds, 130 seconds, 140 seconds, and 150 seconds, respectively. 【0049】 Figure 15 shows an example of actual setup man-hours for a specific worker in this embodiment. Figure 16 shows an example of the correction of standard setup man-hours by the man-hour correction unit in this embodiment. As shown in Figure 15, there are six pieces of actual performance information 54 (performance information by worker) for parts "A001" to "F001" related to welder A, who is scheduled to be in charge of setting up part "G001". The actual setup man-hours 55a for the welding process of parts "A001" to "F001" related to welder A are 80 seconds, 100 seconds, 132 seconds, 143 seconds, 126 seconds, and 120 seconds, respectively, starting with part "A001". As shown in Figure 16, the man-hour correction unit 137 calculates the percentage increase or decrease in man-hours for each actual setup man-hour 55a relative to the standard setup man-hour 52a. 【0050】 Figure 17 shows an example of the correction of standard setup man-hours by the man-hour correction unit of this embodiment. The percentage increase or decrease in the actual setup man-hours 55a for parts "A001" to "F001" performed by welder A, relative to the standard setup man-hours 52a, is -20%, ±0%, +10%, +10%, -10%, and -20% for parts "A001" in that order. The average of these percentage increase or decrease in man-hours is -5%, and as shown in Figure 17, the man-hour correction unit 137 uses this average value of -5% as the correction value for the standard setup man-hours 52a of the welding process for part "G001", thereby correcting the standard setup man-hours 52a of part "G001". The corrected standard setup man-hours 52a (corrected standard setup man-hours 52a') for the welding process of part "G001" is 114 seconds. 【0051】 Similarly, the man-hour correction unit 137 is configured to correct the standard man-hours 52b of the part to be processed based on the individual worker performance information of the worker scheduled to be in charge of processing the part to be processed. The individual worker performance information includes the actual man-hours 55b of parts other than the part to be processed for which the worker was in charge of processing. Specifically, the individual worker performance information is extracted from multiple performance information 54, and only the performance information 54 in which the worker information included in the performance information 54 is that of the worker scheduled to be in charge of processing the part to be processed. 【0052】 Figures 18 and 19 show an example of the standard processing man-hours in this embodiment. For example, as shown in Figure 18, there is a new part "G001" for which there is no performance information 54. The standard processing time 52b for the welding process of part "G001" is 40 seconds / piece. Also, as shown in Figure 19, there are parts "A001" to "F001" which are different from part "G001". The standard processing time 52b for the welding process of parts "A001" to "F001" are 10 seconds / piece, 20 seconds / piece, 30 seconds / piece, 40 seconds / piece, 50 seconds / piece, and 60 seconds / piece, respectively. 【0053】 Figure 20 shows an example of actual processing man-hours performed by a specific worker in this embodiment. As shown in Figure 20, there are six pieces of performance information 54 (performance information by worker) for parts "A001" to "F001" related to welder A, who is scheduled to be in charge of processing part "G001". The actual processing man-hours 55b for the welding process of parts "A001" to "F001" related to welder A are 120 seconds, 360 seconds, 900 seconds, 440 seconds, 1050 seconds, and 1890 seconds, starting with part "A001". In addition, the number of parts "A001" to "F001" produced, as included in each piece of performance information 54, are 10, 20, 30, 10, 20, and 30, starting with part "A001". 【0054】 Figure 21 shows an example of the correction of standard machining man-hours by the man-hour correction unit of this embodiment. As shown in Figure 21, the man-hour correction unit 137 calculates the percentage increase or decrease in man-hours for each actual processing man-hour 55b relative to the standard processing man-hour 52b. Specifically, first, the man-hour correction unit 137 divides the actual processing man-hours 55b for each part "A001" to "F001" by the number of parts "A001" to "F001" produced to calculate the actual processing man-hours 55b per part "A001" to "F001". The actual processing man-hours 55b per part for each actual information 54 of parts "A001" to "F001" are 12 seconds / part, 18 seconds / part, 30 seconds / part, 42 seconds / part, 52.5 seconds / part, and 63 seconds / part, respectively, starting with part "A001". 【0055】 Figure 22 shows an example of the correction of standard machining man-hours by the man-hour correction unit of this embodiment. Then, the percentage increase or decrease in the actual processing time 55b for parts "A001" to "F001" performed by welder A relative to the standard processing time 52b is +20%, -10%, ±0%, +10%, +5%, and +5% for parts "A001" in that order. The average of these percentage increase or decrease in processing time is +5%, and as shown in Figure 22, the processing time correction unit 137 uses this average value +5% as the correction value for the standard processing time 52b of the welding process for part "G001", and corrects the standard processing time 52b of part "G001". The corrected standard processing time 52b (corrected standard processing time 52b') for the welding process of part "G001" becomes 42 seconds / piece. 【0056】 Furthermore, the above-mentioned corrections to the standard setup man-hours 52a and standard machining man-hours 52b can be applied not only to the corrections to the standard setup man-hours 52a and standard machining man-hours 52b of new parts for which there is no performance information 54, but also to the corrections to the standard setup man-hours 52a and standard machining man-hours 52b, or the corrected standard setup man-hours 52a' and corrected standard machining man-hours 52b', of parts for which there is performance information 54. 【0057】 Furthermore, as shown in Figure 4, the man-hour correction unit 137 is configured to perform a correction condition calculation process (S4 in Figure 4) which calculates correction conditions for the provisional setup man-hours PMa from the actual setup man-hours 55a and the inventory history 57, and a man-hour correction process (S5 in Figure 4) which corrects the provisional setup man-hours PMa based on the correction conditions. 【0058】 In the correction condition calculation process, the actual setup man-hours 55a are the actual setup man-hours 55a included in the actual information 54 of the same part as the planned part to be processed, acquired by the actual information acquisition unit 133. Also, the inbound / outbound history 57 are the inbound / outbound history 57 of the same part as the planned part to be processed, acquired by the inventory information acquisition unit 135. Furthermore, the provisional setup man-hours PMa are the standard setup man-hours 52a or the corrected standard setup man-hours 52a' of the planned part to be processed, acquired by the provisional man-hour acquisition unit 131. 【0059】 Specifically, in the correction condition calculation process, the man-hour correction unit 137 calculates a correction condition for the provisional setup man-hours PMa by referring to the provisional setup man-hours PMa of the part to be processed, the actual setup man-hours 55a of the same part as the part to be processed, the number of the same part as the part to be processed produced, and the number of work-in-progress inventory 57a of the same part as the part to be processed immediately before the setup work. 【0060】 Furthermore, in the correction condition calculation process, the man-hour correction unit 137 determines a correction value for the provisional setup man-hours PMa based on the actual setup man-hours 55a of the same part as the part to be processed and the number of work-in-progress inventory 57a immediately before the setup work related to the actual setup man-hours 55a of the same part as the part to be processed, and changes the correction value according to the number of work-in-progress inventory 57a of the part to be processed. 【0061】 Figure 23 shows an example of provisional setup man-hours in this embodiment. Figure 24 shows an example of actual setup man-hours in this embodiment. For example, as shown in Figure 23, there is a part "X001" with a provisional setup time PMa for the welding process of 300 seconds. Part "X001" is a part scheduled for processing. There are two actual data entries 54 for part "X001", as shown in Figure 24. The actual setup time 55a for the welding process in each actual data entry 54 is 300 seconds and 360 seconds. The work dates and times for the setup work in each actual data entry 54 are 17:00 on December 3rd and 17:00 on December 10th. Furthermore, the number of parts "X001" produced in each actual data entry 54 is 100. 【0062】 Figure 25 shows an example of the inventory entry and exit history in this embodiment. The inbound and outbound inventory history 57 of part "X001" is as shown in Figure 25. On December 3rd at 17:00, 100 units of work-in-progress inventory were out, and the number of work-in-progress inventory units 57a at 17:00 on December 3rd was 0. Also, on December 10th at 17:00, 100 units of work-in-progress inventory were out, and the number of work-in-progress inventory units 57a at 17:00 on December 10th was 100. The number of work-in-progress inventory units of part "X001" outbound in these instances matches the number of parts "X001" produced in each performance information 54, indicating that work-in-progress inventory of part "X001" was outbound for setup work. In other words, the number of work-in-progress inventory units 57a of part "X001" immediately before the setup work related to each performance information 54 was 100 and 200. 【0063】 Figure 26 shows an example of the correction of provisional setup man-hours by the man-hour correction unit of this embodiment. First, as shown in Figure 26, the man-hour correction unit 137 calculates the percentage increase or decrease of the man-hours for each actual setup man-hour 55a relative to the provisional setup man-hour PMa. The percentage increase or decrease of the man-hours for each actual setup man-hour 55a relative to the provisional setup man-hour PMa is ±0% and +20%. Next, the man-hour correction unit 137 calculates the correction value and correction conditions by referring to the number of parts "X001" included in each actual information 54 that have been produced, the number of work-in-progress inventory 57a of parts "X001" immediately before the setup work related to each actual information 54, and the calculated percentage increase or decrease. 【0064】 When the work-in-progress inventory of part "X001" (57a) is 100 units, that is, when the work-in-progress inventory of part "X001" (57a) matches the number of parts "X001" produced, the rate of increase or decrease in the actual setup effort (55a) relative to the provisional setup effort (PMa) is ±0%. On the other hand, when the work-in-progress inventory of part "X001" (57a) is 200 units, that is, when the work-in-progress inventory of part "X001" (57a) is greater than the number of parts "X001" produced, the rate of increase or decrease in the actual setup effort (55a) relative to the provisional setup effort (PMa) is +20%. 【0065】 In this case, the man-hour correction unit 137 determines from the actual information 54 on December 10th that the actual setup man-hours 55a have increased by 20% compared to the provisional setup man-hours PMa because there is a difference of 100 units between the work-in-progress inventory 57a of part "X001" and the number of parts "X001" produced. The man-hour correction unit 137 then calculates the correction value as the rate of increase in man-hours per surplus unit of work-in-progress inventory 57a + 0.2% / unit when the work-in-progress inventory 57a of part "X001" is greater than the number of parts "X001" produced. The man-hour correction unit 137 also calculates the corrected provisional setup man-hours PMa by adding the product of the surplus work-in-progress inventory and the correction value to the provisional setup man-hours PMa. 【0066】 On the other hand, the man-hour correction unit 137 determines that there is no difference between the provisional setup man-hours PMa and the actual setup man-hours 55a, since there is no difference between the work-in-progress inventory of part "X001" 57a and the number of parts "X001" produced, based on the actual information 54 for December 3. The man-hour correction unit 137 then sets the correction value to none when the work-in-progress inventory of part "X001" 57a is the same as the number of parts "X001" produced. 【0067】 Figures 27 and 28 show an example of the correction of provisional setup man-hours by the man-hour correction unit of this embodiment. Therefore, as shown in Figure 27, if the man-hour correction unit 137 determines that the work-in-progress inventory number 57a of part "X001" matches the number of parts to be manufactured, it determines that there is no need to correct the provisional setup man-hours PMa and uses the provisional setup man-hours PMa of part "X001" as is for the welding process. On the other hand, as shown in Figure 28, if the man-hour correction unit 137 determines that the work-in-progress inventory number 57a of part "X001" is greater than the number of parts to be manufactured, it determines that there is a need to correct the provisional setup man-hours PMa and corrects the provisional setup man-hours PMa of part "X001" based on a correction value of +0.2% / piece. 【0068】 Specifically, the work-in-progress inventory of part "X001" is 57a, which is 300 units. The planned production quantity is 100 units, so there is a surplus of 200 units in work-in-progress inventory. Therefore, 300 + 200 × 0.002 = 420 seconds becomes the provisional setup time PMa after correction, and the work time correction unit 137 sets 420 seconds as the setup time for the welding process of part "X001". 【0069】 The storage unit 140 has a storage medium such as an HDD (Hard Disk Drive) or SSD (Solid State Drive) and stores various data in a read-write manner. As shown in Figure 2, the storage unit 140 stores the production management program 141. The storage unit 140 also stores programs necessary for controlling each part of the production management device 10. 【0070】 The production management program 141 causes the production management device 10 to execute the following processes: a provisional effort acquisition process to acquire the provisional setup effort PMa of the part to be processed; an actual information acquisition process to acquire actual information 54 including one or more actual setup effort 55a of the same part as the part to be processed; a history acquisition process to acquire the inflow and outflow history 57 of the work-in-progress inventory of the same part as the part to be processed; a correction condition calculation process to calculate correction conditions for the provisional setup effort PMa from the actual setup effort 55a and the inflow and outflow history 57; and an effort correction process to correct the provisional setup effort PMa based on the correction conditions. The corrected provisional setup effort PMa is then used as the setup effort for the part to be processed. 【0071】 Figure 3 is a functional block diagram showing the server of this embodiment. Server 50 has a storage medium such as an HDD or SSD and stores a standard man-hour database 51, a processing performance database 53, and a production technology management database 56, as shown in Figure 3. Various data stored in Server 50 are accessed by the production management device 10, the processing machine 70, and the performance registration terminal 90. Since various known configurations can be used for Server 50 other than the standard man-hour database 51, the processing performance database 53, and the production technology management database 56, a detailed explanation of these configurations is omitted. 【0072】 The standard man-hour database 51 includes multiple standard man-hours 52. Each standard man-hour 52 has a standard setup man-hour 52a, which is the man-hours for setup work, and a standard machining man-hour 52b, which is the man-hours for machining work. The standard man-hour database 51 also includes multiple corrected standard man-hours 52' corrected by the man-hour correction unit 137 of the control unit 130 of the production management device 10. Each corrected standard man-hour 52' ​​has a corrected standard setup man-hour 52a' and a corrected standard machining man-hour 52b'. 【0073】 Regarding the standard man-hours of 52, various known configurations can be adopted, so a detailed explanation will be omitted. 【0074】 The processing performance database 53 includes multiple performance information records 54. The performance information records 54 contain processing performance records for each manufacturing process of products and parts that have been processed in the past. For example, the performance information records 54 include the actual man-hours 55 for each manufacturing process, the working day for each manufacturing process, the number of products and parts produced for each manufacturing process, and worker information for each manufacturing process. The actual man-hours 55 include actual setup man-hours 55a, which are the actual man-hours recorded for setup work, and actual processing man-hours 55b, which are the actual man-hours recorded for processing work. 【0075】 The actual setup man-hours 55a and actual processing man-hours 55b for the manufacturing process using the processing machine 70 can be obtained from the processing records of the processing machine 70. In addition, the actual setup man-hours 55a and actual processing man-hours 55b for the manufacturing process performed manually by the workers can be obtained from the processing records of the performance registration terminal 90. 【0076】 The work date may simply be the date on which the manufacturing process was performed, or it may include the detailed time the work was performed in addition to the date. Worker information can be configured in any way, as long as it contains personally identifiable information such as the worker's name and employee number. 【0077】 The production technology management database 56 includes the inventory receipt and issue history 57 of work-in-progress inventory. The production technology management database 56 also includes the production schedule and process schedule created by the production management device 10, and the sheet data and processing programs used by the processing machine 70. The inventory receipt and issue history 57 includes the quantity of work-in-progress inventory 57a, the receipt / issue date 57b, and the quantity of receipt / issue 57c. The receipt / issue date 57b may simply be the date on which the work-in-progress inventory was received or issued, or it may include the date plus the detailed time on which the work-in-progress inventory was received or issued. 【0078】 The processing machines 70 include blanking machines 70a that process sheets using NC control, and secondary processing machines 70b that process individual work-in-progress after blanking. Examples of blanking machines 70a include laser processing machines, turret punch presses, plasma processing machines, and water jet processing machines. Examples of secondary processing machines 70b include bending machines such as press brakes, NC milling machines, NC lathes, and machining centers. The processing machines 70 are configured to communicate with the production management device 10 and the server 50. 【0079】 Furthermore, the processing machine 70 transmits processing results to the server 50 at the start of processing, the interruption of processing, and the completion of processing. The processing results include, for example, the times corresponding to the start of processing, the interruption of processing, and the completion of processing for each sheet, the actual processing man-hours 55b calculated from those times, and information such as the actual setup man-hours 55a. The actual setup man-hours 55a are registered when the operator inputs the "start" and "completion" of the setup work from the control panel of the processing machine 70 or the results registration terminal 90. Moreover, the method for obtaining the actual setup man-hours 55a is not limited to the above configuration, and the setup time may be automatically measured based on specific operating conditions, for example, the time the mold setup screen is displayed on the control panel of the processing machine 70, and that time may be registered as the actual setup man-hours 55a. 【0080】 The blanking machine 70a performs processing by reading sheet data from the production technology management database 56 stored in the server 50, for example. The secondary processing machine 70b performs processing by reading a processing program from the production technology management database 56 stored in the server 50, for example. 【0081】 The performance registration terminal 90 is a computer such as a desktop PC, laptop computer, or tablet computer, and is connected to the production management device 10 and server 50 via a network. The performance registration terminal 90 is equipped with an input unit (not shown) and a display unit (not shown), and is configured so that the operator can record processing results on the work record screen displayed on the display unit via the input unit. 【0082】 [Production control method according to this embodiment] Next, a production management method using the production management device 10 according to this embodiment will be described. The production management method according to this embodiment generally comprises: a provisional man-hour acquisition step of acquiring provisional setup man-hours PMa of a part to be processed; an actual information acquisition step of acquiring actual information 54 including one or more actual setup man-hours 55a of the same part as the part to be processed; a history acquisition step of acquiring the inflow and outflow history 57 of the work-in-progress inventory of the same part as the part to be processed; a correction condition calculation step of calculating correction conditions for the provisional setup man-hours PMa from the actual setup man-hours 55a and the inflow and outflow history 57; and a man-hour correction step of correcting the provisional setup man-hours PMa based on the correction conditions, and using the corrected provisional setup man-hours PMa as the setup man-hours of the part to be processed. 【0083】 The production management method according to this embodiment will be described in detail with reference to Figure 4. In this embodiment, the corrected standard man-hours 52' are described as being stored in the standard man-hour database 51 of the server 50 in advance, but are not limited to this. Also, in this embodiment, the parts to be processed are described as existing parts for which actual performance information 54 of the same part exists. 【0084】 If the part to be processed is a so-called new product for which no performance information 54 exists for the same part, the production management device 10 calculates a new standard man-hour 52 for the part to be processed and uses that standard man-hour 52 as the man-hour for the part to be processed. Furthermore, if the workers who are scheduled to be in charge of each manufacturing process of the part to be processed have been determined, the production management device 10 uses a corrected standard man-hour 52', which is obtained by correcting the standard man-hour 52 based on the individual performance information of the workers who are scheduled to be in charge of the part to be processed, as the man-hour for the part to be processed. 【0085】 First, the production management device 10 creates order information in response to a product manufacturing request from a customer and arranges for the production of the product. Next, the provisional man-hour acquisition unit 131 of the control unit 130 of the production management device 10 acquires provisional man-hours PM for the parts and products included in the production arrangement (hereinafter referred to as "parts to be processed" in this embodiment) (S1 in Figure 4: Provisional man-hour acquisition process). The provisional man-hours PM include provisional setup man-hours PMa. 【0086】 Specifically, the provisional man-hour acquisition unit 131 of the control unit 130 of the production management device 10 acquires the standard man-hours 52 or corrected standard man-hours 52' of the part to be processed, which are stored in the standard man-hour database 51 of the server 50, as the provisional man-hours PM of the part to be processed. If the provisional man-hour acquisition unit 131 has actual information 54 for the same part as the part to be processed, and there is a corrected standard man-hours 52' of the part to be processed that has been corrected based on that actual information 54, it acquires the standard man-hours 52 (corrected standard man-hours 52') of the part to be processed that has been corrected based on the actual man-hours 55. 【0087】 Furthermore, the provisional man-hour acquisition unit 131 of the control unit 130 of the production management device 10 acquires the standard man-hours 52 (corrected standard man-hours 52') of the part to be processed, corrected based on the worker-specific performance information, if there is no actual performance information 54 for the same part as the part to be processed and the workers who are scheduled to be in charge of each manufacturing process have been determined. 【0088】 After or simultaneously with the provisional man-hour acquisition process, the performance information acquisition unit 133 of the control unit 130 of the production management device 10 acquires performance information 54 for the same part as the planned part from the processing performance database 53 of the server 50 (S2 in Figure 4: performance information acquisition process). The performance information 54 acquired by the performance information acquisition unit 133 includes the actual setup man-hours 55a for each manufacturing process of the same part as the planned part, worker information of the worker in charge of each manufacturing process, the work date for each manufacturing process, and the number of parts of the same part as the planned part produced. 【0089】 Furthermore, the inventory information acquisition unit 135 of the control unit 130 of the production management device 10 acquires the inflow and outflow history 57 of work-in-progress inventory of the same part as the part scheduled for processing from the production technology management database 56 of the server 50 (S3 in Figure 4: history acquisition process). The inflow and outflow history 57 acquired by the inventory information acquisition unit 135 includes the inflow and outflow date 57b of the work-in-progress inventory, the number of work-in-progress inventory items 57a for each inflow and outflow date 57b, and the number of work-in-progress inventory items 57c for each inflow and outflow date 57b. 【0090】 The history acquisition process may be executed after the performance information acquisition process, simultaneously with the performance information acquisition process, or before the performance information acquisition process. Furthermore, the provisional effort acquisition process, the performance information acquisition process, and the history acquisition process may be executed simultaneously. 【0091】 After the provisional man-hour acquisition process, the actual information acquisition process, and the history acquisition process are completed, the man-hour correction unit 137 of the control unit 130 of the production management device 10 calculates correction conditions for the provisional setup man-hours PMa from the actual setup man-hours 55a and the inventory history 57 (S4 in Figure 4: Correction condition calculation process). Specifically, the man-hour correction unit 137 calculates correction conditions for the provisional setup man-hours PMa by referring to the provisional setup man-hours PMa of the part to be processed, the actual setup man-hours 55a of the same part as the part to be processed, the number of the same part as the part to be processed produced, and the number of work-in-progress inventory 57a of the same part as the part to be processed immediately before the setup work. 【0092】 More specifically, the man-hour correction unit 137 of the control unit 130 of the production management device 10 calculates the percentage increase or decrease of the man-hours for each actual setup man-hour 55a relative to the provisional setup man-hours PMa. The man-hour correction unit 137 then calculates the correction conditions and correction values ​​for the provisional setup man-hours PMa based on the relationship between the number of work-in-progress inventory 57a immediately before the setup work related to each actual information 54 is performed and the calculated percentage increase or decrease of man-hours related to each actual information 54. The man-hour correction unit 137 also changes the correction value according to the number of work-in-progress inventory 57a of the parts to be processed. 【0093】 Subsequently, the man-hour correction unit 137 of the control unit 130 of the production management device 10 corrects the provisional setup man-hours PMa based on the calculated correction conditions and correction values, according to the number of work-in-progress inventory 57a of the parts to be processed and the number of parts to be produced (S5 in Figure 4: man-hour correction process). The production management device 10 then uses the corrected provisional setup man-hours PMa as the setup man-hours for the parts to be processed and creates a process schedule by piling up the man-hours for the parts to be processed in the daily process schedule for each process. Through the above steps, a series of production management methods by the production management device 10 according to this embodiment are executed. 【0094】 The production management device 10 may execute the above series of production management methods each time a new production order is placed, or it may execute them collectively for multiple production orders. Furthermore, the production management device 10 can also correct the man-hours already incorporated into the process schedule using the series of production management methods and modify the process schedule. 【0095】 [Advantages of the production management apparatus, production management method, and production management program according to this embodiment] As described above, the production management device 10 according to this embodiment is configured to perform a provisional man-hour acquisition process to acquire a provisional man-hour PMa for parts to be processed, an actual information acquisition process to acquire actual information 54 including one or more actual man-hours 55a for the same parts as the parts to be processed, a history acquisition process to acquire the inflow and outflow history 57 of work-in-progress inventory for the same parts as the parts to be processed, a correction condition calculation process to calculate correction conditions for the provisional man-hour PMa from the actual man-hours 55a and the inflow and outflow history 57, and a man-hour correction process to correct the provisional man-hour PMa based on the correction conditions, and is configured to use the corrected provisional man-hour PMa as the man-hour for the parts to be processed. 【0096】 Furthermore, the production management device 10 according to this embodiment, by having such a configuration, calculates correction conditions for the provisional setup man-hours PMa from the actual setup man-hours 55a and the inventory history 57, and corrects the provisional setup man-hours PMa based on the correction conditions, thereby calculating correction conditions that take into account the inventory status of work-in-progress inventory. Since the provisional setup man-hours PMa is corrected based on these correction conditions, it has the advantage of improving the accuracy of man-hour estimation. 【0097】 Furthermore, in the production management device 10 according to this embodiment, the performance information 54 includes at least the work day of the setup work for each actual setup man-hour 55a and the number of parts produced that are the same as the parts to be processed related to the setup work for each actual setup man-hour 55a, the inventory receipt and issue history 57 includes at least the receipt and issue dates 57b of the work-in-progress inventory and the number of work-in-progress inventory items (work-in-progress inventory items 57a) for each receipt and issue date 57b, and in the correction condition calculation process, the correction conditions for the provisional setup man-hours PMa are calculated by referring to the provisional setup man-hours PMa, the actual setup man-hours 55a, the number of parts produced that are the same as the parts to be processed, and the number of work-in-progress inventory items immediately before the setup work (work-in-progress inventory items 57a). By having such a configuration, the correction conditions are calculated taking into account the difference between the work-in-progress inventory items 57a and the number of parts produced, which has the advantage of being able to further improve the accuracy of man-hour estimation. 【0098】 Furthermore, in the correction condition calculation process, the production management device 10 determines a correction value for the provisional setup man-hours PMa according to the actual setup man-hours 55a and the number of work-in-progress inventory (work-in-progress inventory 57a) immediately before the setup work related to the actual setup man-hours 55a, and changes the correction value according to the number of work-in-progress inventory (work-in-progress inventory 57a) of the parts to be processed. By having such a configuration, it is possible to make optimal corrections to the provisional setup man-hours PMa according to the number of work-in-progress inventory 57a of the parts to be processed, which has the advantage of further improving the accuracy of man-hour estimation. 【0099】 Furthermore, in the production management device 10 according to this embodiment, the provisional setup man-hours PMa are the standard setup man-hours 52a for the parts to be processed. This configuration has the advantage of reducing the time required to estimate man-hours. 【0100】 Furthermore, in the production management device 10 according to this embodiment, the provisional setup man-hours PMa is the man-hours obtained by correcting the standard setup man-hours 52a of the part to be processed based on the actual setup man-hours 55a (corrected standard setup man-hours 52a'). By having such a configuration, it is possible to further improve the accuracy of man-hour estimation compared to the case where the standard setup man-hours 52a are corrected. 【0101】 Furthermore, the production management device 10 according to this embodiment is configured to calculate the rate of increase or decrease of man-hours relative to the standard setup man-hours 52a for each actual setup man-hour 55a, and to correct the standard setup man-hours 52a based on the average value of the rate of increase or decrease. By having such a configuration, the accuracy of estimation can be further improved. 【0102】 Furthermore, in the production management device 10 according to this embodiment, the provisional setup man-hours PMa are the man-hours (corrected standard setup man-hours 52a') obtained by correcting the standard setup man-hours 52a of the part to be processed based on the actual performance information of the workers who are scheduled to be in charge of the setup work for the part to be processed.
