Description
[Technical field]
[0001] The present invention relates to a cost management device, a manufacturing support system, a cost management method, and a cost management program. [Background technology]
[0002] Conventionally, there is a cost management device equipped with an estimated cost calculation unit that calculates an estimated cost, which is an estimated cost for a sheet metal processing process, an actual cost calculation unit that calculates an actual cost, which is an actual cost incurred for the process, and a profit calculation unit that calculates the difference between the estimated cost and the actual cost as profit (Patent Document 1, etc.). The estimated cost is calculated by multiplying the estimated processing time, which is the processing time estimated for the process related to the process information, by the cost required per hour for the process related to the process information. Also, the actual cost is calculated by multiplying the actual processing time, which is the processing time actually required for the process related to the process information, by the cost required per hour for the process related to the process information.

[0003] [Patent Document 1] Patent Publication No. 2021-22329 Summary of the Invention [Problem to be solved by the invention]
[0004] However, conventional cost management devices simply calculate the estimated cost, the actual cost, and the difference between the estimated cost and the actual cost, and leave it entirely to the user to consider the validity of the estimated cost and review the actual cost.

[0014] The best mode for carrying out the present invention will be described below with reference to the drawings. Note that the following embodiments do not limit the inventions according to the claims, and all of the combinations of features described in the embodiments are not necessarily essential to the solution of the invention.
[0015] [Overall configuration of the manufacturing support system according to this embodiment] FIG. 1 is a schematic diagram showing a manufacturing support system according to an embodiment of the present invention. First, a manufacturing support system 1 according to an embodiment of the present invention will be outlined with reference to Fig. 1. The manufacturing support system 1 according to this embodiment is a manufacturing support system that manages the cost of a product including one or more parts. As shown in Fig. 1, the manufacturing support system 1 generally includes a cost management device 100. The manufacturing support system 1 also includes a production management device 10, a processing machine 70, and a performance registration terminal 200. These devices are connected to each other so that they can communicate with each other.
[0016] In this embodiment, a product is an item that has undergone all manufacturing processes in a factory and is ready to be delivered to a customer, and includes one or more parts.
[0017] The manufacturing process of the product includes, for example, a blanking process in which a metal plate of a fixed length (hereinafter, referred to as a sheet in this embodiment) is cut into an arbitrary shape, a sorting process in which the work-in-progress on the sheet is sorted 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, and deburring. The assembly process includes welding, screwing, and the like.
[0018] The production management device 10, the processing machine 70, the cost management device 100, and the result registration terminal 200 are connected to each other so as to be able to communicate with each other via a private network such as a local network or an intranet. When connected by wireless communication, the manufacturing support system 1 may further include one or more access points AP.
[0019] The production management device 10 comprises a production management section (not shown) and a standard cost calculation section (not shown). The production management section manages order information, product information, manufacturing process information for products and parts, and progress information for each manufacturing process. The production management section also makes arrangements for the production of products. Furthermore, the production management section issues serial numbers to the ordered products and the parts that make up the products. Furthermore, when making arrangements for the production of a product, the production management section creates production arrangement information 12 for the product. The production management section transmits the created production arrangement information 12 to the processing machine 70 and the performance registration terminal 200.
[0020] FIG. 4 is a diagram showing an example of production arrangement information according to the present embodiment. As shown in Fig. 4, the production arrangement information 12 includes product information and parts information. The production arrangement information 12 also includes business partner and parts data, etc. The product information includes, for example, the product name, production delivery date of the product, scheduled date of processing of the product, manufacturing process information of the product, quantity of the product (ordered number), product serial number, information on materials, etc. The parts information includes, for example, the part name, production delivery date of the part, scheduled date of processing of the part, manufacturing process information of the part, quantity of the part (ordered number), part serial number (part number), information on materials, etc.
[0021] The part data is design data (drawing data) that indicates the shape of the part, for example, CAD (computer-aided design) data of the part. The manufacturing process information is information that indicates a series of manufacturing processes until the product is completed. The information on materials is, for example, the type of material, plate thickness, etc.
[0022] Fig. 5 is a diagram showing an example of a process unit price in this embodiment. Fig. 6 is a diagram showing an example of a standard cost in this embodiment. The standard cost calculation unit estimates the man-hours required for manufacturing based on the production arrangement information 12, and multiplies the estimated man-hours (in this embodiment, the expected man-hours) by the standard value of the process unit cost 14 to calculate the standard cost 16. The standard cost calculation unit transmits the calculated standard cost 16 to the cost management device 100. In this embodiment, the man-hours are the time (minutes) required for producing (processing) products and parts.
[0023] Here, an example of calculation of the standard cost 16 by the standard cost calculation unit is shown. For example, as shown in Fig. 5, a standard value of the process unit cost 14 is set for each manufacturing process. The standard value of the process unit cost 14 for the blanking process is 100 yen / min, the standard value of the process unit cost 14 for the bending process is 200 yen, and the standard value of the process unit cost 14 for the welding process is 300 yen.
[0024] FIG. 6 is a diagram showing an example of the standard cost according to the present embodiment. As shown in Fig. 6, the standard cost calculation unit multiplies the standard value of the process unit price 14 of each manufacturing process by the expected man-hours of each part to calculate the standard cost 16. For example, the standard cost 16 of the blanking process per part A (part number "A001") included in the production arrangement information 12 shown in Fig. 4 is 100 yen. The standard cost 16 of the bending process per part A is 600 yen. Furthermore, the standard cost 16 of the welding process per part B (part number "B001") is 1500 yen.
[0025] FIG. 2 is a functional block diagram showing the cost management device of this embodiment. The cost management device 100 is an electronic computer such as a desktop personal computer, a laptop computer, or a tablet terminal, and includes an input unit 110, a display unit 120, a control unit 130, and a memory unit 140, as shown in FIG. 2.
[0026] The input unit 110 is composed of input devices such as a keyboard, a mouse, a touchpad, a joystick, etc., and by operating the input unit 110, in addition to the function of inputting information that is usually required in the cost management device 100, it is possible to perform operations such as setting a first allowable range of the actual result reflected cost 146 described later and creating analysis conditions (conditional expressions) for the cost analysis described later. With such a configuration, the cost management device 100 can manually change the first allowable range of the actual result reflected cost 146 to any range via the input unit 110.
[0027] The display unit 120 has a display as a display device, and in addition to the screen display function normally required in the cost management device 100, displays, for example, a cost management screen 122. The display unit 120 may also be configured as a touch panel having the function of the input unit 110. When the display unit 120 is configured as a touch panel, a user can input various information, such as the setting of the first allowable range of the actual result reflected cost 146, to the cost management device 100 by operating the display unit 120, for example.
[0028] The configurations of the input unit 110 and the display unit 120 are not limited to the above-mentioned configurations, and are not limited to those as long as they are replaced by configurations having equivalent functions to the input unit 110 and the display unit 120 (for example, a display means or input means that can be used remotely, etc.).
[0029] FIG. 13 is a diagram showing an example of a cost management screen according to this embodiment. 13, the cost management screen 122 includes an extraction result display area 122a that displays confirmation-required costs CC extracted by a confirmation-required cost extraction process of the control unit 130, which will be described later. The cost management screen 122 also includes a cost analysis display area 122b that displays the results of an analysis of information about the cost of products by a cost analysis unit 135 of the control unit 130, which will be described later. The cost management screen 122 also includes a cost list display area 122c that displays a list of actual product reflected costs 146 that are tracked and sequentially stored by a cost fluctuation tracking unit 136 of the control unit 130, which will be described later.
[0030] In this embodiment, the display unit 120 may be configured to simultaneously display the extraction result display area 122a, the cost analysis display area 122b, and the cost list display area 122c on one screen, as shown in Fig. 13, or each display area may be displayed on a separate screen. When configured to simultaneously display the extraction result display area 122a, the cost analysis display area 122b, and the cost list display area 122c on one screen, it is possible to view information on one cost management screen 122, eliminating the need to switch screens, which has the advantage of reducing the burden on the user.
[0031] The control unit 130 is configured, for example, by an integrated arithmetic processing device having a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit). As shown in FIG. 2, the control unit 130 includes a processing record acquisition unit 131, an hourly rate acquisition unit 132, a cost calculation unit 133, a confirmation-required cost extraction unit 134, a cost analysis unit 135, and a cost fluctuation tracking unit 136.
[0032] Fig. 3 is a flowchart showing an example of a process executed by the control unit of the cost management device of the present embodiment. Fig. 7 is a diagram showing an example of the processing record of the present embodiment. As shown in Fig. 3, the processing history acquisition unit 131 is configured to be able to execute an actual time acquisition process (S1 in Fig. 3) for acquiring an actual time AT taken to manufacture a product. Specifically, as shown in Fig. 7, the processing history acquisition unit 131 acquires a processing history MP, which will be described later, from the processing machine 70 and the history registration terminal 200. The processing history MP includes an actual time AT. In addition, in the actual time acquisition process, the processing history acquisition unit 131 acquires an actual time AT for each manufacturing process in a series of manufacturing processes for the product.
[0033] Furthermore, the processing result acquisition unit 131 stores the acquired result time AT in a result time storage unit 141 (described later) of the memory unit 140, and updates a histogram in which all past result times AT of the product are aggregated. With such a configuration, it has an advantage that all past result times AT of the product can be represented while suppressing the data capacity of the result time storage unit 141.
[0034] As shown in Fig. 3, the hourly rate acquisition unit 132 is configured to be able to execute an hourly rate acquisition process (S2 in Fig. 3) for acquiring hourly rates 144 of equipment and workers involved in the production of the product. Specifically, the hourly rate acquisition unit 132 acquires hourly rates 144 of equipment and workers involved in the production of the product from an hourly rate storage unit 143 (described later) in the memory unit 140. In this embodiment, the hourly rate 144 means a cost per hour. Also, in this embodiment, the hourly rate 144 is a cost per minute, but is not limited to this and may be a cost per hour.
[0035] FIG. 8 is a diagram showing an example of the hour rate according to the present embodiment. The hourly rate 144 (equipment cost) of the equipment involved in the manufacturing of the processing machine 70 and the like is determined, for example, in consideration of the depreciation cost of the equipment, the cost of consumables, the cost of electricity, the cost of fuel, and the like. The hourly rate 144 (labor cost) of the worker is determined in consideration of the salary of the worker, and the like. In this embodiment, the hourly rate 144 of the equipment is set to a standard value common to a plurality of pieces of equipment as shown in FIG. 8. The hourly rate 144 of the equipment is configured so that a different value can be set for each piece of equipment. Furthermore, the hourly rate 144 of the worker is set to a standard value common to a plurality of workers. Furthermore, the hourly rate 144 of the worker is configured so that a different value can be set for each worker.
[0036] In this embodiment, the hourly rate acquisition unit 132 acquires, in principle, the hourly rate 144 of the equipment and the hourly rate 144 of the worker, but is not limited to this. When using equipment that does not involve a worker, the hourly rate acquisition unit 132 may acquire only the hourly rate 144 of that equipment.
[0037] For example, the standard hourly rate 144 of equipment is 100 yen / min, and the individually set hourly rates 144 of equipment L and equipment M are 80 yen / min and 150 yen / min, respectively, as shown in Fig. 8. The standard hourly rate 144 of a worker is 150 yen / min, and the individually set hourly rates 144 of worker X and worker Y are 200 yen / min and 120 yen / min, respectively.
[0038] FIG. 9 is a schematic diagram showing an example of calculation of the actual result reflected cost in this embodiment. The cost calculation unit 133 is configured to be capable of executing an actual performance reflected cost calculation process (S4 in FIG. 3) for calculating the actual performance reflected cost 146 of a product using the actual performance time AT, as shown in FIG. 3. In this embodiment, the "actual performance reflected cost" means a cost taking into consideration the processing actual performance MP of the product.
[0039] 9, the cost calculation unit 133 calculates an actual result reflected cost 146 based on the actual result time AT acquired by the processing result acquisition unit 131 and the hourly rate 144 acquired by the hourly rate acquisition unit 132. In addition, the cost calculation unit 133 stores the calculated actual result reflected cost 146 in an actual result reflected original price storage unit 145 of the storage unit 140, which will be described later.
[0040] Furthermore, in the actual result reflected cost calculation process, the cost calculation unit 133 calculates the actual result reflected cost 146 for each individual manufacturing process of the series of manufacturing processes of the product. For example, in the case of product A included in the production arrangement information 12 shown in Fig. 4, product A is composed of part A. Therefore, the cost calculation unit 133 calculates the actual result reflected cost 146 of the blanking process and the actual result reflected cost 146 of the bending process of part A, and calculates the actual result reflected cost 146 of product A by adding up the actual result reflected cost 146 of the blanking process and the actual result reflected cost 146 of the bending process.
[0041] As shown in FIG. 7 and FIG. 9, the total of the performance time AT of the equipment N in the bending process of the part A is 270 minutes. The hour rate 144 of the equipment N is not set individually and is a standard 100 yen / min. Therefore, the actual performance reflected cost 146 of the equipment N is 27,000 yen obtained by multiplying the total of the performance time AT of the equipment N by the hour rate 144 of the equipment N. Furthermore, the total of the performance time AT of the worker X in the bending process of the part A is 270 minutes, and the hour rate 144 of the worker X is 200 yen / min as described above. Therefore, the actual performance reflected cost 146 of the worker X is 54,000 yen. Furthermore, the total of the performance time AT of the worker Y is 180 minutes, and the hour rate 144 of the worker Y is 120 yen / min as described above. Therefore, the actual performance reflected cost 146 of the worker Y is 21,600 yen.
[0042] Therefore, the reflected actual cost 146 for the processing result MP of the bending process of the part A shown in FIG. 7 is 102,600 yen, which is the sum of the reflected actual cost 146 of the equipment N, the reflected actual cost 146 of the worker X, and the reflected actual cost 146 of the worker Y. In addition, since the production quantity of the part A is 100 pieces, the reflected actual cost 146 in the bending process per piece of the part A is 1,026 yen. In addition, the cost calculation unit 133 calculates the reflected actual cost in the blanking process in the same manner. For example, the reflected actual cost 146 in the blanking process is 120 yen. In this case, the reflected actual cost per piece of the part A is 1,146 yen, which is the sum of the reflected actual cost 146 in the blanking process and the reflected actual cost 146 in the bending process. And, since product A is composed of one part A, the actual cost reflected in price 146 per unit of product A is 1,146 yen.
[0043] 3, the cost calculation unit 133 is configured to further execute an actual time determination process (S3 in FIG. 3) for determining whether the actual time AT acquired by the processing result acquisition unit 131 is within a predetermined second allowable range, and is configured not to execute the above-mentioned actual result reflected cost calculation process when it is determined that the actual time AT is outside the second allowable range. That is, in this embodiment, the cost calculation unit 133 is configured to execute the actual result reflected cost calculation process only when it is determined that the actual time AT acquired by the processing result acquisition unit 131 is within the second allowable range.
[0044] Furthermore, the cost calculation unit 133 is configured to calculate an average value of the performance time AT for each part and each manufacturing process, and to successively update and accumulate the calculated average value, in order to use it as an operand of the analysis condition described later, or as feedback to the production management device 10. And, when the cost calculation unit 133 determines that the performance time AT is outside the second allowable range, it is configured to exclude the performance time AT from the data when calculating and updating the average value of the performance time AT.
[0045] The cost calculation unit 133 is configured to determine the second allowable range of the actual time AT based on a histogram of the past actual time AT of the product. Specifically, the cost calculation unit 133 calculates a normal distribution of the past actual time AT, and determines the interval of ±3σ from the average value of the calculated normal distribution of the actual time AT as the second allowable range of the actual time AT.
[0046] As shown in FIG. 3, the cost to be confirmed extraction unit 134 is configured to execute an actual result reflected cost determination process (S5 in FIG. 3) for determining whether the actual result reflected cost 146 is within a predetermined first tolerance range, a cost to be confirmed extraction process (S6 in FIG. 3) for extracting the actual result reflected cost 146 as a cost to be confirmed CC if it is determined that the actual result reflected cost 146 is outside the first tolerance range, and a cost to be confirmed display process (S7 in FIG. 3) for displaying the extracted cost to be confirmed CC on the display unit 120.
[0047] When the confirmation-required cost extraction unit 134 determines that the actual result reflected cost 146 is within the first allowable range, the confirmation-required cost extraction unit 134 does not extract the actual result reflected cost 146 as a confirmation-required cost CC.
[0048] FIG. 10 is a schematic diagram showing an example of extraction of the to-be-confirmed costs in this embodiment. The cost to be confirmed extraction unit 134 also determines a first allowable range of the reflected actual cost 146 based on the past reflected actual cost 146 of the product. The first allowable range of the reflected actual cost 146 is, for example, a range of ±30% of the previous reflected actual cost 146 of the product, as shown in FIG. 10. If the previous reflected actual cost 146 of the product A is 750 yen, the first allowable range of the reflected actual cost 146 of the product A is 525 yen or more and 975 yen or less. If the previous reflected actual cost 146 of the product B is 1,200 yen, the first allowable range of the reflected actual cost 146 of the product B is 840 yen or more and 1,560 yen or less.
[0049] The past actual reflected cost 146 of the product is not limited to the previous actual reflected cost 146. The past actual reflected cost 146 of the product may be, for example, the actual reflected cost 146 before the previous one, or may be an average value of a plurality of past actual reflected costs 146. In addition, the first allowable range of the actual reflected cost 146 may be different between the range from the past actual reflected cost 146 of the product to the upper limit and the range from the past actual reflected cost 146 of the product to the lower limit. For example, the first allowable range of the actual reflected cost 146 may be -20% to +30% of the past actual reflected cost 146 of the product, or may be -15% to +5%.
[0050] Furthermore, in this embodiment, the first allowable range of the actual result reflected cost 146 is configured to be manually changeable to an arbitrary range by the user via the input unit 110. Also, the actual result reflected cost 146 of the comparison target used as the product's past actual result reflected cost 146 is configured to be manually changeable to an arbitrary range by the user via the input unit 110.
[0051] As shown in FIG. 10, the current actual reflected cost 146 of product A is 1,146 yen, which is outside the first allowable range of the actual reflected cost 146 (525 yen or more and 975 yen or less). Therefore, in the confirmation-required cost extraction process, the confirmation-required cost extraction unit 134 extracts the actual reflected cost 146 of product A as the confirmation-required cost CC. On the other hand, the current actual reflected cost 146 of product B is 1,000 yen, which is within the first allowable range of the actual reflected cost 146 (840 yen or more and 1,560 yen or less). Therefore, in the confirmation-required cost extraction process, the confirmation-required cost extraction unit 134 does not extract the actual reflected cost 146 of product B.
[0052] In the confirmation-required cost display process, the confirmation-required cost extraction unit 134 displays the extracted confirmation-required cost CC in the extraction result display area 122a of the cost management screen 122 displayed on the display unit 120, as shown in Fig. 13. In the example shown in Fig. 10, the confirmation-required cost extraction unit 134 displays the actual result reflected cost 146 of product A as the confirmation-required cost CC in the extraction result display area 122a of the cost management screen 122.
[0053] FIG. 11 is a diagram showing an example of the cost analysis according to the present embodiment. The cost analysis unit 135 is configured to be able to analyze information relating to the cost of a product based on an analysis condition that combines a plurality of operands. Specifically, as shown in Fig. 11, a user can create an arbitrary analysis condition (conditional expression) by selecting and combining operand candidates, numbers, and operators via the input unit 110. The cost analysis unit 135 analyzes information relating to the cost of a product based on the analysis condition created by the user.
[0054] 11, the operand candidates include the product's standard cost 16 and the product's actual cost reflected cost 146. The operand candidates may include the previous standard cost 16 and the standard cost before the previous one 16 in addition to the latest standard cost 16. In this embodiment, the cost analysis unit 135 is configured to obtain the standard cost 16 required for analysis from the production management device 10.
[0055] The operand candidates may include the previous actual cost 146 and the actual cost 146 before the previous one in addition to the latest actual cost 146. Furthermore, the operand candidates may include the actual cost 146 for each individual manufacturing process in addition to the actual cost 146 that is the sum of the actual cost 146 for a series of manufacturing processes. Furthermore, the operand candidates may include the average value of a plurality of past actual cost 146.
[0056] The information on the cost of a product is, for example, the accuracy of the standard cost 16, an improvement activity evaluation value in a certain manufacturing process, etc. In the example shown in FIG. 11, a conditional formula of "(("standard cost"-"actual reflected cost") / "standard cost") x 100" is created as an analysis condition for analyzing the accuracy of the standard cost 16. Also, for example, the improvement activity evaluation value in the bending process is expressed as ""actual reflected cost of bending process (previous)"-"actual reflected cost of bending process (present)." The cost analysis unit 135 displays the analysis results in the cost analysis display area 122b of the cost management screen 122 displayed on the display unit 120.
[0057] FIG. 12 is a diagram showing an example of cost fluctuation tracking in this embodiment. The cost fluctuation tracking unit 136 is configured to be able to sequentially store the actual performance reflected costs 146 of the products. Specifically, as shown in Fig. 12, the user is configured to be able to select a product for which the user wishes to track the fluctuation of the actual performance reflected costs 146 via the input unit 110. The cost fluctuation tracking unit 136 sequentially stores the actual performance reflected costs 146 of the products selected by the user, and tracks the fluctuation of the actual performance reflected costs 146.
[0058] Moreover, the cost fluctuation tracing unit 136 is configured to display a list of the stored actual reflected costs 146 on the display unit 120. Specifically, the cost fluctuation tracing unit 136 displays the list of the stored actual reflected costs 146 in a cost list display area 122c of the cost management screen 122 displayed on the display unit 120. Moreover, the products to be traced can be grouped as a tracing group that groups together a plurality of products to be traced, and the cost fluctuation tracing unit 136 displays the tracing results for each registered tracing group.
[0059] The tracking of the fluctuation of the actual cost reflected 146 may be terminated by, for example, the user manually deleting the product to be tracked, or a tracking period may be set in advance.
[0060] Furthermore, in addition to the product selected by the user, the cost fluctuation tracking unit 136 may automatically add, for example, a product related to the actual reflected cost 146 extracted as a cost CC by the cost to be confirmed extraction unit 134 as a tracking target, and track the fluctuation of the actual reflected cost 146 of that product.
[0061] The memory unit 140 has a storage medium such as a hard disk drive (HDD) or a solid state drive (SSD), and stores various data in a readable and writable manner. As shown in FIG. 2, the memory unit 140 includes a performance time storage unit 141, an hour rate storage unit 143, and a performance reflected original price storage unit 145. The memory unit 140 also stores a cost management program 147. The memory unit 140 further stores programs necessary for controlling each unit of the cost management device 100.
[0062] The actual time storage unit 141 stores the actual time AT acquired by the processing actual result acquisition unit 131. The hourly rate storage unit 143 stores the hourly rate 144 of the equipment used in each manufacturing process. The hourly rate storage unit 143 also stores the hourly rate 144 of the worker in charge of each manufacturing process. The actual result reflected original price storage unit 145 stores the actual result reflected cost 146 calculated by the cost calculation unit 133 of the control unit 130.
[0063] The cost management program 147 causes the cost management device 100 to execute an actual time acquisition process that acquires the actual time AT required for manufacturing a product containing one or more parts, an actual reflected cost calculation process that calculates the actual reflected cost 146 of the product using the actual time AT, an actual reflected cost determination process that determines whether the actual reflected cost 146 is within a predetermined first tolerance range, a cost to be confirmed extraction process that extracts the actual reflected cost 146 as a cost to be confirmed CC if the actual reflected cost 146 is outside the first tolerance range, and a cost to be confirmed display process that displays the extracted cost to be confirmed CC on the display unit 120.
[0064] The processing machine 70 is, for example, a CNC (Computer Numerical Control) machine tool, such as a blanking machine 70a that processes sheets, or a secondary processing machine 70b that processes individual work-in-progress after blanking. The blanking machine 70a is, for example, a laser processing machine, a turret punch press, a shearing machine, a plasma processing machine, a water jet processing machine, or the like. The secondary processing machine 70b is, for example, a bending machine such as a press brake, a panel bender, or a bending robot, an NC milling machine, an NC lathe, a machining center, a welding robot, or the like. The processing machine 70 is configured to be able to communicate with the production management device 10 and the cost management device 100.
[0065] The processing machine 70 is configured to be able to record the actual time AT, and is configured to transmit the recorded actual time AT to the cost management device 100. Specifically, the processing machine 70 transmits the processing results MP to the cost management device 100 at the start of processing, the interruption of processing, and the completion of processing. The processing results MP includes information such as the time and actual time AT corresponding to the start of processing, the interruption of processing, and the completion of processing for each sheet, and the number of parts produced.
[0066] The result registration terminal 200 is an electronic computer such as a desktop computer, a notebook computer, or a tablet terminal, and is connected to the production management device 10, the cost management device 100, etc. via a network. The result registration terminal 200 includes an input unit (not shown) and a display unit (not shown). The display unit of the result registration terminal 200 is configured to be able to display a result input screen. It is preferable that one result registration terminal 200 is placed in each work area of the manufacturing process that does not use the processing machine 70, but this is not limited to this.
[0067] The result registration terminal 200 is configured to be able to record the result time AT and to transmit the recorded result time AT to the cost management device 100. The user is also configured to be able to record the processing result MP on a result input screen displayed on the display unit of the result registration terminal 200 via the input unit of the result registration terminal 200. Specifically, the user receives the production arrangement information 12 transmitted from the production management device 10 at the result registration terminal 200 and performs work in the target manufacturing process. Then, when the user signals the start, interruption, and end of work via the input unit of the result registration terminal 200 on the result input screen of the production arrangement information 12 for the manufacturing process in which the user is working, the result registration terminal 200 records the date and time of the signal and calculates the result time AT.
[0068] Furthermore, the user can input additional information such as information on the worker, the equipment used, and the work content on the result input screen via the input unit of the result registration terminal 200. Furthermore, the user inputs the number of pieces actually produced (production number) on the result input screen. After that, by confirming the registration of this information, a processing result MP is created, which includes the times corresponding to the start of processing, the interruption of processing, and the completion of processing, the calculated result time AT, the additional information, and the production number. After creating the processing result MP, the result registration terminal 200 transmits the processing result MP to the cost management device 100.
[0069] [Cost management method according to this embodiment] Next, a cost management method by the cost management device 100 according to this embodiment will be described. The cost management method according to this embodiment includes an actual time acquisition step in which the cost management device 100 acquires an actual time AT required for manufacturing a product including one or more parts, an actual result reflected cost calculation step in which the cost management device 100 calculates an actual result reflected cost 146 of the product using the actual result time AT, an actual result reflected cost determination step in which the cost management device 100 determines whether the actual result reflected cost 146 is within a predetermined first allowable range, a confirmation-required cost extraction step in which the cost management device 100 extracts the actual result reflected cost 146 as a confirmation-required cost CC if the actual result reflected cost 146 is outside the first allowable range, and a confirmation-required cost display step in which the extracted confirmation-required cost CC is displayed on the display unit 120 of the cost management device 100.
[0070] In addition, the cost management method according to this embodiment includes an hour rate acquisition process for acquiring hour rates 144 of equipment and workers involved in the production of the product using the cost management device 100, and an actual time determination process for determining whether the acquired actual time AT is within a predetermined second tolerance range.
[0071] FIG. 14 is a flowchart showing an example of a cost management method according to this embodiment. The cost management method according to this embodiment will be described in detail with reference to FIG. 14. First, the production management device 10 creates production arrangement information 12 in response to a product production request from a customer (S10 in FIG. 14), and makes production arrangements for each production process (S11 in FIG. 14). Specifically, the production management device 10 transmits the created production arrangement information 12 to the processing machine 70 and the track record registration terminal 200. In the case of a production process that uses the processing machine 70, the user receives the production arrangement information 12 at the processing machine 70. Also, in the case of a production process that does not use the processing machine 70, the user receives the production arrangement information 12 at the track record registration terminal 200. Below, a production process that does not use the processing machine 70 will be described as an example, but the present invention is not limited to this.
[0072] The user checks the contents of the production arrangement information 12 on the result registration terminal 200 and performs the work. At that time, the user signals the start, interruption, and end of the work via the input section of the result registration terminal 200 on the result input screen of the production arrangement information 12 for the manufacturing process in which the work is to be performed. The result registration terminal 200 records the date and time of the signal, and calculates the result time AT. Furthermore, the user inputs additional information and the production quantity via the input section of the result registration terminal 200 on the result input screen.
[0073] After that, the user operates the result registration terminal 200 and confirms the registration of information, whereby the result registration terminal 200 creates and registers the processing result MP including the times corresponding to the start of processing, the interruption of processing, and the completion of processing, the calculated result time AT, the additional information, and the production quantity (S200 in FIG. 14). Then, the result registration terminal 200 transmits the processing result MP to the cost management device 100.
[0074] Next, the processing result acquisition unit 131 of the control unit 130 of the cost management device 100 acquires the processing result MP including the result time AT (S100 in FIG. 14: result time acquisition step). In addition, the hourly rate acquisition unit 132 of the control unit 130 acquires the hourly rate 144 of the equipment used in the manufacturing process for which the processing result MP was acquired from the hourly rate storage unit 143 of the memory unit 140, and the hourly rate 144 of the worker in charge of the work in the manufacturing process (S110 in FIG. 14: hourly rate acquisition step).
[0075] Furthermore, the cost calculation unit 133 of the control unit 130 of the cost management device 100 judges whether the performance time AT acquired by the processing performance acquisition unit 131 of the control unit 130 is within the second allowable range (S120 in FIG. 14: performance time judgment step). If it is judged that the performance time AT is outside the second allowable range (NO in S120 in FIG. 14), the cost calculation unit 133 does not calculate the performance reflected cost 146. Furthermore, the cost management device 100 ends the series of steps.
[0076] When it is determined that the actual result time AT acquired by the processing result acquisition unit 131 of the control unit 130 of the cost management device 100 is within the second allowable range (YES in S120 of FIG. 14), the cost calculation unit 133 of the control unit 130 calculates the actual result reflected cost 146 of the product based on the actual result time AT and the hour rate 144 acquired by the hour rate acquisition unit 132 of the control unit 130 (S130 of FIG. 14: actual result reflected cost calculation step). The cost calculation unit 133 stores the calculated actual result reflected cost 146 in the actual result reflected original price storage unit 145 of the storage unit 140.
[0077] Thereafter, the confirmation-required cost extraction unit 134 of the control unit 130 of the cost management device 100 judges whether the actual result reflected cost 146 calculated by the cost calculation unit 133 of the control unit 130 is within a predetermined first allowable range (S140 in FIG. 14: actual result reflected cost judgment step). If it is judged that the actual result reflected cost 146 is outside the first allowable range (NO in S140 in FIG. 14), the confirmation-required cost extraction unit 134 extracts the actual result reflected cost 146 as a confirmation-required cost CC (S150 in FIG. 14: confirmation-required cost extraction step).
[0078] Then, the confirmation-required cost extraction unit 134 of the control unit 130 of the cost management device 100 displays the extracted confirmation-required cost CC in the extraction result display area 122a of the cost management screen 122 of the display unit 120 (S160 in FIG. 14: confirmation-required cost display step). On the other hand, if it is determined that the actual result reflected cost 146 is within the first allowable range (YES in S140 in FIG. 14), the confirmation-required cost extraction unit 134 does not extract the actual result reflected cost 146. The cost management device 100 then ends the series of steps. Through the above steps, a series of cost management methods by the cost management device 100 according to this embodiment is executed.
[0079] [Advantages of the cost management device, manufacturing support system, cost management method, and cost management program according to the present embodiment] As described above, the cost management device 100 of this embodiment is equipped with a display unit 120 and a control unit 130, and the control unit 130 is configured to be able to execute an actual time acquisition process that acquires the actual time AT required for manufacturing a product including one or more parts, an actual reflected cost calculation process that calculates the actual reflected cost 146 of the product using the actual time AT, an actual reflected cost determination process that determines whether the actual reflected cost 146 is within a predetermined first tolerance range, a cost to be confirmed extraction process that extracts the actual reflected cost 146 as a cost to be confirmed CC if it is determined that the actual reflected cost 146 is outside the first tolerance range, and a cost to be confirmed display process that displays the extracted cost to be confirmed CC on the display unit 120.
[0080] Furthermore, by being equipped with such a configuration, the cost management device 100 of this embodiment automatically extracts only the actual reflected costs 146 that require confirmation and presents them to the user via the display unit 120, thereby having the advantage of enabling appropriate cost management while reducing the burden on the user.
[0081] In the cost management device 100 according to this embodiment, the control unit 130 acquires the actual time AT for each manufacturing process of the series of manufacturing processes of the product in the actual time acquisition process, and calculates the actual result reflected cost 146 for each manufacturing process in the actual result reflected cost calculation process. With this configuration, the actual result reflected cost 146 is calculated for each individual manufacturing process, which has the advantage of enabling accurate calculation of the actual result reflected cost 146 and more appropriate cost management.
[0082] Furthermore, by calculating the actual result reflected cost 146 for each individual manufacturing process, it is possible to identify the main manufacturing process that has a large effect on the change in the actual result reflected cost 146. Furthermore, even if the actual result time AT cannot be obtained for some manufacturing processes, it is possible to identify the manufacturing process for which the actual result time AT cannot be obtained, and it is also possible to confirm the actual result reflected cost 146 for the manufacturing process for which the actual result time AT can be obtained.
[0083] Furthermore, in the cost management device 100 according to this embodiment, the control unit 130 determines a first allowable range of the actual result reflected cost 146 based on the product's past actual result reflected cost 146. With this configuration, it is possible to determine a first allowable range appropriate for each product, which has the advantage of enabling more appropriate cost management.
[0084] Furthermore, the cost management device 100 according to this embodiment includes an input unit 110, which is configured to allow a user to manually change the first allowable range of the actual result reflected cost 146 to an arbitrary range via the input unit 110. This configuration has the advantage that a range of the confirmation-required costs CC to be extracted in accordance with the user's operational environment can be determined, making it possible to present a practical confirmation-required cost CC.
[0085] Furthermore, in the cost management device 100 according to this embodiment, the control unit 130 is configured to be capable of further executing an actual time determination process for determining whether the acquired actual time AT is within a predetermined second allowable range, and is configured not to execute an actual reflected cost calculation process when it is determined that the actual time AT is outside the second allowable range. With this configuration, when the actual time AT is a so-called outlier, the actual reflected cost 146 is calculated based on the actual time AT, and extraction as a cost CC to be confirmed can be prevented. This has the advantage that the user does not need to confirm unnecessary information, the burden on the user can be reduced, and more appropriate cost management can be achieved.
[0086] In addition, one of the reasons for variations in the actual time AT is forgetting to signal the start, interruption, and end of work, which can result in unintended actual time AT being recorded. However, by excluding actual time AT that falls outside the second tolerance range, the average value of the actual time AT used in analyzing information related to costs can be maintained at a reliable value.
[0087] Furthermore, in the cost management device 100 according to this embodiment, the control unit 130 is configured to determine the second allowable range of the performance time AT based on a histogram of the past performance times AT of the product. This configuration has the advantages of being able to represent all of the past performance times AT of the product while suppressing the data capacity of the performance time storage unit 141, and being able to remove outliers of the performance times AT with a relatively small amount of calculation.
[0088] Furthermore, in the cost management device 100 according to this embodiment, the actual performance reflected cost 146 is calculated based on the actual performance time AT and the hourly rates 144 of the equipment and workers involved in the production of the product. With this configuration, there is an advantage that the actual performance reflected cost 146 can be compared for each product or each production process.
[0089] In the cost management device 100 according to the present embodiment, the hourly rate 144 is set to a standard value common to a plurality of pieces of equipment, and is also configured to be able to set different values for each piece of equipment. With conventional cost management devices, there were cases where all of the hourly rates 144 had to be set individually to calculate costs, and the complexity of setting the hourly rates 144 made it difficult for users to use the device. However, with this configuration, the hourly rate 144 can be set individually only for pieces of equipment that deviate from the standard value, based on the standard value, which has the advantage of reducing the burden on the user and enabling appropriate cost management.
[0090] Furthermore, in the cost management device 100 according to this embodiment, the hourly rate 144 is set to a standard value common to a plurality of workers, and is also configured to be able to set different values for each worker. With conventional cost management devices, there were cases where all hourly rates 144 had to be set individually to calculate costs, and the cumbersome task of setting the hourly rates 144 made it difficult for users to use the device. However, with this configuration, the hourly rate 144 can be set individually only for workers whose hourly rate deviates from the standard value, which has the advantage of reducing the burden on the user and enabling appropriate cost management.
[0091] Furthermore, in the cost management device 100 according to this embodiment, the control unit 130 is configured to be able to analyze information related to the cost of a product based on analysis conditions that combine multiple operands, and the operand candidates include the product's standard cost 16 and the product's actual cost reflected 146. With this configuration, it is possible to easily analyze information related to costs simply by creating analysis conditions by combining multiple operands from among the operand candidates prepared in advance, which has the advantage of reducing the burden on the user. In addition, the user can freely create analysis conditions to suit his / her own operating environment, which has the advantage of enabling a highly flexible analysis and appropriate cost management.
[0092] Moreover, in the cost management device 100 according to this embodiment, the control unit 130 is configured to be able to sequentially store the actual results reflected costs 146 of the products, and is also configured to display a list of the stored actual results reflected costs 146 on the display unit 120. With this configuration, the user can grasp the state of fluctuations in the actual results reflected costs 146 at a glance, and there is no need for the user to check the actual results reflected costs 146 each time, monitor the state of fluctuations in the actual results reflected costs 146 by himself, or search for the stored actual results reflected costs 146. This has the advantage of reducing the burden on the user while enabling appropriate cost management.

However, this is not limiting.
