[0011] The embodiments described below each illustrate a specific example of the present disclosure. The numerical values, shapes, materials, components, component placement and connection configurations, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components that are not recited in independent claims are described as optional components.

[0012] (Embodiment) 1 is a block diagram showing the functional configuration of a cost calculation system 10 according to an embodiment of the present invention. The functional configuration of the cost calculation system 10 will be described with reference to FIG.

[0013] As shown in FIG. 1, cost calculation system 10 is a system for calculating the cost of a part. For example, the part is not a general-purpose part but a part that has undergone some processing. Specifically, the part is, for example, a resin molded part, a metal pressed part, or cardboard. Cost calculation system 10 includes an acquisition unit 11, a storage unit 12, a calculation unit 13, and an output unit 14. For example, cost calculation system 10 is realized by providing a processor, a memory, a communication module, etc. in a single housing. Alternatively, for example, acquisition unit 11, storage unit 12, calculation unit 13, and output unit 14 may be provided in multiple housings.

[0014] The acquisition unit 11 acquires part information and the like related to parts whose costs are to be calculated. For example, the part information includes information indicating the shape of the part, information indicating the dimensions of the part, information indicating the weight of the part, information indicating the volume of the part, information indicating the projected area of ​​the part, and information indicating the material of the part. For example, the acquisition unit 11 is communicably connected to a user terminal 20 and acquires part information input using the user terminal 20. Furthermore, for example, the acquisition unit 11 acquires CAD data of the part and acquires the part information from the CAD data. For example, the CAD data is two-dimensional data or three-dimensional data. Note that the acquisition unit 11 may also acquire the part information by reading it from a drawing on which the part is drawn, for example, by performing image analysis on the drawing.

[0015] The user terminal 20 has an input device 21 and an output device 22. The input device 21 is a device for the user to input part information, etc. The output device 22 is a device for displaying information output by the output unit 14, etc. For example, the user inputs part information using the input device 21, and the user terminal 20 transmits the part information input by the user to the acquisition unit 11. The acquisition unit 11 acquires the part information by receiving the part information transmitted from the user terminal 20. For example, the user terminal 20 is a personal computer, the input device 21 is a keyboard, and the output device 22 is a display.

[0016] The storage unit 12 stores information necessary for calculating the cost of parts, etc. Specifically, for example, the storage unit 12 stores information necessary for calculating the amount of each of a plurality of expense items.

[0017] FIG. 2 is a diagram showing expense items and the like for calculating the cost of a part. As shown in FIG. 2, for example, the multiple expense items include material costs, processing costs, secondary material costs, secondary processing costs, others, and transportation costs. For example, the others include costs required for inspecting the part and costs required for packaging the part. Material costs are costs required for the material of the part, processing costs are costs required for processing the part, secondary material costs are costs required for the secondary material of the part, secondary processing costs are costs required for secondary processing of the part, and transportation costs are costs required for transporting the part.

[0018] The storage unit 12 stores a plurality of primary parameters for calculating the amount of each of a plurality of expense items. Here, the storage unit 12 stores a plurality of primary parameters for calculating the amount of material costs and a plurality of primary parameters for calculating the amount of processing costs.

[0019] Here, the multiple primary parameters for calculating the material cost include the material unit price, the material weight scale, and the scrap selling price. The material unit price is the price of the material per unit weight, the material weight scale is the weight of the material used to manufacture a part, and the scrap selling price is the price of the scrap material generated when a part is manufactured using the purchased material.

[0020] The primary parameters for calculating the processing cost include a molding machine rate and a man-hours total. The molding machine rate is an example of the cost per unit time required to process a part, and the man-hours total is an example of the time required to process a part.

[0021] The storage unit 12 stores a plurality of secondary parameters for calculating primary parameters. Here, the storage unit 12 stores a plurality of secondary parameters for calculating a material weight meter, which is a primary parameter for calculating the amount of material costs, and a plurality of secondary parameters for calculating a molding machine rate, which is a primary parameter for calculating the amount of processing costs.

[0022] Here, the plurality of secondary parameters for calculating the material weight meter include the product weight, the SR weight, the SR reuse weight, the mold change / setup weight, the reject weight, and the purge weight.

[0023] Here, the sprue, runner, and gate are collectively referred to as the SR. The sprue is the channel into which the resin (plastic) injected from the injection molding machine first flows in the mold. For example, the cross section of a sprue is circular, with its sides sloped. The length of the sprue must be equal to the thickness of the mold (fixed side). The runner is the channel into which the resin flows after the sprue. When molding two or more parts (molded products), the runner branches into two or more, and the resin injected from the injection molding machine flows toward each of two or more molding spaces for molding two or more parts. The gate is the final channel through which the resin passes, serving as the entrance to the molding space where the part is molded. The gate's role is to control the speed at which the resin flows in.

[0024] The SR weight per shot is the weight of the SR portion formed by SR in one shot. The SR weight is the weight of the SR portion per part, and is calculated by dividing the SR weight per shot by the number of parts. For example, for a mold that can form two parts in one shot, the SR weight is calculated by dividing the SR weight per shot by 2.

[0025] Parts are used separately from the SR portion formed by SR. For example, the SR portion may be discarded or may be finely crushed and remelted to be reused as resin material. Here, the weight of the SR portion that is reused per part is defined as the SR recycled weight. For example, if all the SR portion is discarded and not reused, the SR recycled weight = 0.

[0026] Here, the number of cavities in the mold is referred to as the cavity count. The more cavities there are, the more parts can be molded in one shot, reducing the production cost per part.

[0027] Furthermore, when molding one lot of parts using an injection molding machine is completed and molding of the next part begins, work may be performed that includes discharging and cleaning the resin material inside the injection molding machine. Resin is used in this work. Here, the amount of resin used in this work is referred to as the purge weight.

[0028] Furthermore, when molding of one lot of parts using an injection molding machine is completed and molding of the next part begins, a production (trial) of around 10 to 15 parts may be carried out to confirm that the injection molding machine is set to the correct molding conditions and is in a state where it can stably produce good parts. Here, the weight of the resin consumed in this production (trial) and the purge weight are added together to form the mold changeover / setup weight.

[0029] Here, the weight of the defective parts that occur during production is defined as the defective weight. For example, if 1000 parts weighing 80g are produced and 10 defective parts occur, the defective weight = 80 x 10 / (1000-10) = 0.8g.

[0030] The multiple secondary parameters for calculating the molding machine rate include direct labor costs, equipment costs, operating costs, building costs, and administrative costs per unit time. Direct labor costs are an example of personnel costs. For example, direct labor costs are the costs for workers involved in processing parts, equipment costs are the costs required for the equipment used to process parts, operating costs are the costs required to operate the equipment used to process parts, and building costs are the costs required for the building in which the equipment used to process parts is installed. For example, administrative costs are the costs required for managing workers involved in processing parts, the equipment used to process parts, and the building in which the equipment used to process parts is installed.

[0031] The storage unit 12 stores a plurality of tertiary parameters for calculating the secondary parameters. Here, the storage unit 12 stores a plurality of tertiary parameters for calculating the SR weight, which is a secondary parameter for calculating the material weight scale.

[0032] Here, the multiple tertiary parameters for calculating the SR weight include the SR weight per shot and the number of cavities. As mentioned above, the SR weight per shot is the weight of the SR portion formed by SR in one shot. Also, as mentioned above, the number of cavities in the mold is the number of cavities.

[0033] For example, each of the plurality of tertiary parameters is obtained by a questionnaire or the like given to a supplier. That is, for example, each of the plurality of tertiary parameters is acquired in advance from the supplier and stored in the storage unit 12. This allows the calculation unit 13 to calculate the secondary parameters using the plurality of tertiary parameters. For example, the supplier is a parts manufacturer or the like.

[0034] Furthermore, for example, each of the plurality of secondary parameters is obtained by a questionnaire or the like given to the supplier. That is, for example, each of the plurality of secondary parameters is acquired in advance from the supplier and stored in the storage unit 12. This allows the calculation unit 13 to calculate the primary parameter using the plurality of secondary parameters.

[0035] Furthermore, for example, each of the multiple primary parameters is obtained by a questionnaire or the like sent to the supplier. That is, for example, each of the multiple primary parameters is acquired in advance from the supplier and stored in the storage unit 12. This allows the calculation unit 13 to calculate the amount of the expense item using the multiple primary parameters.

[0036] FIG. 3 is a first table showing information stored in the cost calculation system 10 of FIG. 1. As shown in FIG. 3, the memory unit 12 stores information about suppliers. Specifically, the memory unit 12 stores information indicating the names of suppliers' companies, their abbreviations, etc. The memory unit 12 also stores information about suppliers' factories. Specifically, the memory unit 12 stores information indicating the items of parts manufactured at the suppliers' factories and the names of the suppliers' factories. The memory unit 12 also stores information about suppliers' machines. Specifically, the memory unit 12 stores information indicating the manufacturers of the equipment used at the suppliers' factories and the model numbers of the equipment used at the suppliers' factories. For example, this information can be obtained by, for example, conducting a survey of suppliers.

[0037] FIG. 4 is a second table showing information stored in the cost calculation system 10 of FIG. 1. As shown in FIG. 4, the storage unit 12 stores information related to material prices. Specifically, the storage unit 12 stores the unit price of materials for each of a plurality of material manufacturers. For example, this information can be obtained by conducting a questionnaire survey of suppliers (material manufacturers).

[0038] FIG. 5 is a third table showing information stored in the cost calculation system 10 of FIG. 1. As shown in FIG. 5, the memory unit 12 acquires and stores information about the unit price of scrap. Specifically, the memory unit 12 acquires and stores information about the unit price of scrap for each raw material of a material. For example, information about the unit price of scrap can be obtained from newspapers, etc.

[0039] 2, the calculation unit 13 calculates the amount of each of a plurality of expense items based on the part information acquired by the acquisition unit 11, and calculates the cost of the part using the calculated amounts. Here, the calculation unit 13 calculates the cost of the part by adding up the calculated amounts. For example, the calculation unit 13 calculates the cost of the part for each of a plurality of suppliers.

[0040] The calculation unit 13 calculates the amount of at least one of the multiple expense items using multiple primary parameters. Here, the calculation unit 13 calculates the amount of material costs using multiple primary parameters, and calculates the amount of processing costs using multiple primary parameters. Specifically, the calculation unit 13 calculates the material costs by multiplying the material unit price by the total material weight minus the scrap selling price. The calculation unit 13 also calculates the processing costs by multiplying the molding machine rate by the total man-hours.

[0041] The calculation unit 13 calculates at least one of the plurality of primary parameters using a plurality of secondary parameters. Here, the calculation unit 13 calculates the material weight meter using a plurality of secondary parameters, and calculates the molding machine rate using a plurality of secondary parameters. Specifically, the calculation unit 13 calculates the material weight meter by (product weight) + (SR weight) - (SR reuse weight) + (mold change / setup weight) + (defective weight) + (purged weight). In addition, the calculation unit 13 calculates the molding machine rate by (direct labor cost) + (equipment cost) + (power cost) + (building cost) + (management cost).

[0042] The calculation unit 13 calculates at least one of the plurality of secondary parameters using the plurality of tertiary parameters. Here, the calculation unit 13 calculates the SR weight using the plurality of tertiary parameters. Specifically, the calculation unit 13 calculates the SR weight by (SR weight per shot) / (number of shots taken).

[0043] The calculation unit 13 calculates the theoretical lowest price for each of the multiple expense items by using multiple primary parameters, etc. obtained from the supplier through a questionnaire, etc., as described above, and calculates the theoretical lowest price for the cost of the parts by using the theoretical lowest price for each of the multiple expense items.

[0044] 1, the output unit 14 outputs cost information indicating the cost calculated by the calculation unit 13. For example, the output unit 14 outputs the cost information by transmitting the cost information to the output device 22.

[0045] The functional configuration of the cost calculation system 10 and the like according to the embodiment has been described above.

[0046] Fig. 6 is a flowchart showing an example of the operation of calculating the cost of a part by the cost calculation system 10 of Fig. 1. With reference to Fig. 6, an example of the operation of the cost calculation system 10 for calculating the cost of a part will be described.

[0047] 6, the acquiring unit 11 acquires part information related to a part (acquisition step) (step S1). As described above, for example, the acquiring unit 11 acquires part information input using the user terminal 20 or part information from CAD data of the part.

[0048] When the acquisition unit 11 acquires the part information, the calculation unit 13 calculates the amount of each of the multiple expense items based on the part information acquired by the acquisition unit 11, and calculates the cost of the part using the calculated multiple amounts (calculation step) (step S2). Here, as described above, the calculation unit 13 calculates the amount of at least one of the multiple expense items using multiple primary parameters.

[0049] An example of the operation of the cost calculation system 10 to calculate the cost of a part has been described above.

[0050] 7 to 16 are first to tenth diagrams showing examples of screens displayed on the output device 22. Another example of the operation of the cost calculation system 10 will be described with reference to FIGS.

[0051] As shown in FIG. 7, the cost calculation system 10 displays a login information acceptance screen on the output device 22. Here, the login information includes a username, a password, and a language. Note that the acceptance of the login information does not have to be performed. When the user inputs the login information using the input device 21, the input login information is transmitted to the cost calculation system 10, and the cost calculation system 10 accepts the login information.

[0052] 8, when the cost calculation system 10 receives the login information, it displays a menu screen on the output device 22. Specifically, for example, the cost calculation system 10 displays an icon for "New parts selection / quote request," an icon for "quote receipt," an icon for "master management," an icon for "system management," and the like.

[0053] For example, when the user clicks on the "New Part Selection / Quote Request" icon, the cost calculation system 10 displays a basic information screen on the output device 22, as shown in Fig. 9. Specifically, for example, the cost calculation system 10 displays created projects and an icon 23 for adding a new project. When calculating the cost for the first time, the user clicks the icon 23 for adding a new project to create a new project, selects the created new project, and clicks the "OK" icon.

[0054] When the user selects a new project and clicks the "OK" icon, the cost calculation system 10 displays a detailed information input screen on the output device 22, as shown in FIG. 10. The detailed information input screen accepts input of part information. Here, the part information includes information on the "estimation premise" that is the premise for estimating the cost, information on the "material" of the part, information on the "processing" of the part, information on the "secondary processing" of the part, information on the "secondary material" of the part, information on the "mold" for manufacturing the part, information on the "proposed number of parts" for the part, and information on the "shipping inspection and packaging" of the part.

[0055] It should be noted that, for example, the cost calculation system 10 does not need to accept input of all of this information, and may accept input of only the required information among this information. For example, if the required information has not been input, the cost calculation system 10 displays an error on the output device 22.

[0056] When a user inputs part information and clicks the "Select Candidate Supplier" icon, the cost calculation system 10 calculates the cost based on the input part information and displays a supplier selection screen on the output device 22 as shown in FIG. 11. Specifically, for example, the cost calculation system 10 calculates the cost of each part from multiple suppliers and displays the cost of each part from the multiple suppliers. For example, multiple suppliers are displayed in order of lowest cost.

[0057] When the user selects some of the multiple suppliers and clicks the "Theoretical Estimate Comparison" icon, the cost calculation system 10 displays a theoretical estimate comparison screen on the output device 22, as shown in Fig. 12. Specifically, for example, the cost calculation system 10 displays the costs of one or more suppliers selected by the user.

[0058] When the user selects one or more suppliers and clicks the "detailed comparison" icon, the cost calculation system 10 displays a detailed comparison screen on the output device 22, as shown in Fig. 13. Specifically, for example, the cost calculation system 10 displays a breakdown of the costs of each of the one or more suppliers selected by the user. Here, the breakdown of the costs includes material specifications and unit prices, material costs, processing costs, secondary material costs, secondary processing costs, others, and shipping costs.

[0059] For example, when the user clicks on the ">" next to the processing cost, the molding machine rate and labor hours, which are primary parameters for calculating the processing cost, are displayed. Furthermore, when the user clicks on the word molding machine rate, for example, the cost calculation system 10 causes the output device 22 to display a molding machine rate factor confirmation / change screen, as shown in FIG. 14. Specifically, for example, the cost calculation system 10 displays multiple secondary parameters for calculating the molding machine rate. Here, the multiple secondary parameters for calculating the molding machine rate include direct labor costs, equipment costs, operating costs, building costs, and management costs.

[0060] For example, the molding machine rate factor confirmation / change screen accepts changes to secondary parameters, etc. Specifically, for example, cost calculation system 10 accepts changes to operating costs, changes to personnel, changes to the number of tons, and changes to the tie bar spacing / injection capacity list. When the user changes secondary parameters, etc. and clicks the "recalculate theoretical value" icon, cost calculation system 10 recalculates the molding machine rate using the changed secondary parameters, etc., and recalculates the cost of the part using the recalculated molding machine rate.

[0061] When the user clicks the "Confirm theoretical value" icon, the screen returns to the screen shown in Fig. 13, and when the user clicks the "Output quotation request" icon, the cost calculation system 10 saves the calculated cost. The cost saved in this way can be viewed by clicking the "Receive quotation" icon shown in Fig. 8.

[0062] When the user clicks the "quote receipt" icon, the cost calculation system 10 displays a quotation receipt list screen as shown in Fig. 15. Specifically, for example, the cost calculation system 10 displays the cost etc. for each case for which "quote request output" has been made.

[0063] When the user clicks the "Estimate Comparison" icon, the cost calculation system 10 displays an estimate comparison screen on the output device 22, as shown in FIG. 16. Specifically, for example, the cost calculation system 10 displays theoretical values ​​indicating the costs calculated by the cost calculation system 10 and actual values ​​indicating the costs presented by the supplier. For example, a mark (see dotted circle) is displayed next to an expense item for which there is a difference of 20% or more between the theoretical value and the actual value. Furthermore, for example, if there is a difference of 20% or more between the theoretical value and the actual value of a primary parameter, a mark (see dotted square) is displayed next to the expense item related to that primary parameter.

[0064] When the user selects a supplier and clicks the "Supplier Selection Report Output" icon, a report for that supplier is output.

[0065] An example of another operation of the cost calculation system 10 has been described above.

[0066] 17 is an eleventh diagram showing an example of a screen displayed on the output device 22. With reference to FIG. 17, an example of another operation of the cost calculation system 10 will be described.

[0067] 17, for example, the acquisition unit 11 acquires CAD data and acquires part information from the CAD data. The calculation unit 13 calculates the cost of the part based on the part information acquired from the CAD data. Here, the CAD data is 3D data.

[0068] The cost calculation system 10 further includes an extraction unit that refers to the CAD data acquired by the acquisition unit 11 and extracts a portion of the part that is associated with any of a plurality of expense items. For example, the extraction unit is realized by a processor or the like, and is provided together with the acquisition unit 11 and the like in a single housing.

[0069] For example, each of a plurality of expense items is linked in advance to the shape of the part, and the extraction unit extracts and displays the part of the part that is linked to the expense item selected by the user. Also, for example, CAD data includes information indicating the processed part of the part, and when the processing cost is selected by the user, the extraction unit extracts and displays the part as the part related to the processing cost.

[0070] Specifically, for example, the CAD data includes information indicating that the outer shape of the part is formed by cutting and that the curved portion of the part is formed by bending.

[0071] For example, if the first process is a cutting process and the user clicks on the words "Processing Cost" for the first process, the extraction unit extracts the outer shape of the part, and the outer shape of the part is highlighted (for example, shown with a thick line) as the part associated with the processing cost.

[0072] Also, for example, if the second process is a bending process and the user clicks on the words "processing cost" for the second process, the extraction unit extracts the bending portion of the part, and the bending portion of the part is highlighted as the part associated with the processing cost (for example, shown by a thick line).

[0073] An example of another operation of the cost calculation system 10 has been described above.

[0074] 18 is a twelfth diagram showing an example of a screen displayed on the output device 22. With reference to FIG. 18, an example of still another operation of the cost calculation system 10 will be described.

[0075] 18, for example, when the acquiring unit 11 reads CAD data, the cost calculation system 10 indicates parts of the part that have design issues. For example, the cost calculation system 10 indicates parts of the part that have design issues by representing the parts of the part that have design issues with a thick line.

[0076] For example, if two adjacent holes formed in a part are close to each other, the cost calculation system 10 will show the two holes with a thick line and display a message indicating that the part may be torn. Furthermore, for example, the cost calculation system 10 may display a list of multiple parts having a similar shape to the part in question, and display information on a part selected by the user from the list. This allows the user to find out how similar issues were resolved in parts manufactured in the past.

[0077] An example of yet another operation of the cost calculation system 10 has been described above.

[0078] 19 to 21 are thirteenth to fifteenth diagrams showing examples of screens displayed on the output device 22. Another example of the operation of the cost calculation system 10 will be described with reference to FIGS.

[0079] 19, for example, the cost calculation system 10 displays an input screen that accepts input of part information such as the part manufacturing region, part size, and secondary processing of the part. When the user inputs the part information and clicks the "search with this condition" icon, the cost calculation system 10 searches for suppliers that can manufacture the part related to the input part information.

[0080] As shown in FIG. 20 , for example, the cost calculation system 10 displays one or more suppliers that can manufacture the parts related to the input part information. For example, the cost calculation system 10 displays, for each of the one or more suppliers, the status, cost, number of molding machines, on-board quality, painting equipment, number of laser processing machines, production capacity, etc. For example, the cost calculation system 10 displays the status of a recommended supplier as “recommended,” the status of an existing supplier as “existing,” and the status of a new supplier as “new.”

[0081] As shown in FIG. 21, for example, the cost calculation system 10 quantifies the management, future prospects, cost strength, technology, quality, and CSR of one or more suppliers, and displays the status of suppliers with high scores as "recommended."

[0082] An example of yet another operation of the cost calculation system 10 has been described above.

[0083] The cost calculation system 10 according to the embodiment is a cost calculation system that calculates the cost of parts, and includes an acquisition unit 11 that acquires part information related to the parts, and a calculation unit 13 that calculates the amount of each of a plurality of expense items based on the part information acquired by the acquisition unit 11 and calculates the cost of the parts using the calculated amounts, and the calculation unit 13 calculates the amount of at least one of the plurality of expense items using a plurality of primary parameters.

[0084] According to this, the calculation unit 13 calculates the amount of at least one of the multiple expense items using multiple primary parameters, so that the amount of at least one of the multiple expense items can be calculated more accurately, and the cost of the part can be calculated more accurately.

[0085] In the cost calculation system 10 according to the embodiment, the calculation unit 13 calculates the theoretical lowest cost of the parts.

[0086] This allows the theoretical lowest cost of the parts to be calculated with greater accuracy.

[0087] In the cost calculation system 10 according to the embodiment, the calculation unit 13 calculates at least one of the plurality of primary parameters using the plurality of secondary parameters.

[0088] This allows at least one of the plurality of primary parameters to be calculated with higher accuracy, and the cost of the part to be calculated with even higher accuracy.

[0089] In addition, in the cost calculation system 10 according to the embodiment, the multiple expense items include processing costs, and the multiple primary parameters for calculating the amount of processing costs include the cost per unit time required to process the part (molding machine rate) and the time required to process the part (man-hours total).

[0090] This allows for more accurate calculation of processing costs and more accurate calculation of the cost of parts.

[0091] In addition, in the cost calculation system 10 according to the embodiment, the multiple secondary parameters for calculating the cost per unit time required to process a part (molding machine rate) include labor costs, equipment costs, operating costs, building costs, and management costs per unit time.

[0092] This allows the cost per unit time required to process a part (molding machine rate) to be calculated more accurately, and the cost price of the part to be calculated more accurately.

[0093] In the cost calculation system 10 according to the embodiment, the acquisition unit 11 acquires CAD data of the part and acquires part information from the CAD data.

[0094] This allows for more accurate part information to be acquired, allowing for more accurate calculation of part costs.

[0095] Moreover, the cost calculation system 10 according to the embodiment further includes an extraction unit that refers to the CAD data and extracts a portion of the part that is related to any one of a plurality of expense items.

[0096] This allows extraction of a location in a part that is related to any one of a plurality of expense items, making it easy to recognize at which location in the part that expense item is incurred.

[0097] (Other embodiments, etc.) While the cost calculation system according to one or more aspects of the present disclosure has been described above based on the embodiments, the present disclosure is not limited to these embodiments. As long as they do not deviate from the spirit of the present disclosure, various modifications conceivable by a person skilled in the art to the present embodiments and forms constructed by combining components of different embodiments may also be included within the scope of one or more aspects of the present disclosure.

[0098] In the above-described embodiment, the calculation unit 13 calculates at least one of the plurality of primary parameters using a plurality of secondary parameters, but this is not limiting. For example, the calculation unit 13 may not use a plurality of secondary parameters, and may acquire all of the plurality of primary parameters from a supplier or the like.

[0099] Furthermore, in the above-described embodiment, the cost calculation system 10 includes the acquisition unit 11, the storage unit 12, the calculation unit 13, and the output unit 14. However, the present invention is not limited to this. For example, the cost calculation system 10 may include the calculation unit 13, rather than the acquisition unit 11, the storage unit 12, and the output unit 14. In this case, for example, one or more devices, etc., different from the cost calculation system 10 include the acquisition unit 11, the storage unit 12, and the output unit 14 collectively or in a distributed manner, and the cost calculation system 10 calculates the amount of each of the multiple expense items and calculates the cost of the parts by communicating with the devices, etc.
