Furthermore, among the components in the following embodiments, components that are not recited in independent claims are described as optional components.

(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.

As shown in FIG. 1, cost calculation system 10 is a system that calculates the cost of parts. For example, the parts in question are not general-purpose parts, but parts that have undergone some kind of processing. Specifically, the parts in question are, for example, resin molded parts, metal pressed parts, or cardboard. Cost calculation system 10 includes an acquisition unit 11, a memory unit 12, a calculation unit 13, and an output unit 14. For example, cost calculation system 10 is realized by providing a processor, memory, communication module, etc. in a single housing. Furthermore, for example, acquisition unit 11, memory unit 12, calculation unit 13, and output unit 14 may be distributed across multiple housings.

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 communicatively connected to a user terminal 20 and acquires part information input using the user terminal 20. Also, for example, the acquisition unit 11 acquires CAD data for the part and acquires 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 part information by reading it from a drawing on which the part is drawn, for example, by performing image analysis on the drawing.

The user terminal 20 has an input device 21 and an output device 22. The input device 21 is a device that allows the user to input part information, etc. The output device 22 is a device that displays information output by the output unit 14. 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.

The memory unit 12 stores information necessary for calculating the cost of parts. Specifically, for example, the memory unit 12 stores information necessary for calculating the amount of each of multiple expense items.

Figure 2 is a diagram showing expense items used to calculate the cost of a part. As shown in Figure 2, for example, the multiple expense items include material costs, processing costs, secondary material costs, secondary processing costs, other costs, and transportation costs. For example, the other costs include the cost of inspecting the part and the cost of packaging the part. Material costs are the costs required for the material of the part, processing costs are the costs required for processing the part, secondary material costs are the costs required for the secondary material of the part, secondary processing costs are the costs required for secondary processing of the part, and transportation costs are the costs required for transporting the part.

The memory unit 12 stores multiple primary parameters for calculating the amount of each of multiple expense items. Here, the memory unit 12 stores multiple primary parameters for calculating the amount of material costs and multiple primary parameters for calculating the amount of processing costs.

Here, the multiple primary parameters used to calculate the material cost amount 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 purchased material.

The multiple primary parameters used to calculate the processing cost include a molding machine rate and a man-hour meter. The molding machine rate is an example of the cost per unit time required to process a part, and the man-hour meter is an example of the time required to process a part.

The memory unit 12 stores multiple secondary parameters for calculating primary parameters. Here, the memory unit 12 stores multiple secondary parameters for calculating the material weight meter, which is a primary parameter for calculating the material cost amount, and multiple secondary parameters for calculating the molding machine rate, which is a primary parameter for calculating the processing cost amount.

Here, the multiple secondary parameters used to calculate the material weight scale include product weight, SR weight, SR reuse weight, mold change/setup weight, defective weight, and purge weight.

Here, the sprue, runner, and gate are collectively referred to as the SR. The sprue is the channel in the mold into which the resin (plastic) injected/filled from the injection molding machine first flows. For example, the cross section of a sprue is circular, and the sides of the sprue are sloped. The length of the sprue needs to be the same as 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/filled from the injection molding machine flows toward each of two or more molding spaces for molding two or more parts. The gate is the channel through which the resin finally passes, and is the entrance to the molding space where the part is molded. The role of the gate is to control the speed at which the resin flows in.

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.

Parts are used separately from the SR portion formed using SR. For example, the SR portion may be discarded, or it may be crushed into small pieces, remelted, and reused as resin material. Here, the weight of each SR portion that is reused is referred to as the SR recycled weight. For example, if all SR portions are discarded and not reused, the SR recycled weight = 0.

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

In addition, 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 involves 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.

In addition, when molding 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 able to consistently produce good parts. Here, the weight of resin consumed in this production (trial) and the purge weight are added together to form the mold change/setup weight.

Here, the weight of defects that occur during production is referred to as the defective weight. For example, if 1,000 parts weighing 80g are produced and 10 defects occur, the defective weight = 80 x 10 / (1,000 - 10) = 0.8g.

Furthermore, the multiple secondary parameters used to calculate the molding machine rate include direct labor costs, equipment costs, operating costs, building costs, and management 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. Furthermore, for example, management costs are the costs required for managing workers involved in processing parts, managing the equipment used to process parts, and managing the building in which the equipment used to process parts is installed.

The memory unit 12 stores multiple tertiary parameters for calculating secondary parameters. Here, the memory unit 12 stores multiple tertiary parameters for calculating the SR weight, which is a secondary parameter for calculating the material weight scale.

Here, the multiple tertiary parameters used to calculate the SR weight include the SR weight per shot and the number of pieces. As mentioned above, the SR weight per shot is the weight of the SR portion molded by the SR in one shot. Also, as mentioned above, the number of pieces is the number of cavities in the mold.

For example, each of the multiple tertiary parameters is obtained by, for example, conducting a survey of suppliers. That is, for example, each of the multiple 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 multiple tertiary parameters. For example, the supplier is a parts manufacturer, etc.

Furthermore, for example, each of the multiple secondary parameters can be obtained by, for example, conducting a questionnaire survey of the supplier. In other words, for example, each of the multiple secondary parameters can be acquired in advance from the supplier and stored in the memory unit 12. This allows the calculation unit 13 to calculate the primary parameter using the multiple secondary parameters.

Furthermore, for example, each of the multiple primary parameters can be obtained by, for example, conducting a survey of the supplier. In other words, for example, each of the multiple primary parameters can be acquired in advance from the supplier and stored in the memory unit 12. This allows the calculation unit 13 to calculate the amount of the expense item using the multiple primary parameters.

Figure 3 is a first table showing information stored in the cost calculation system 10 of Figure 1. As shown in Figure 3, the memory unit 12 stores information about suppliers. Specifically, the memory unit 12 stores information indicating the supplier's company name, the supplier's company abbreviation, etc. The memory unit 12 also stores information about the supplier's factory. Specifically, the memory unit 12 stores information indicating the items of parts manufactured at the supplier's factory and the supplier's factory name, etc. The memory unit 12 also stores information about the supplier's machinery. Specifically, the memory unit 12 stores information indicating the manufacturer of the equipment used at the supplier's factory and the model number of the equipment used at the supplier's factory, etc. This information can be obtained, for example, by conducting a survey of suppliers, etc.

Figure 4 is a second table showing information stored in the cost calculation system 10 of Figure 1. As shown in Figure 4, the memory unit 12 stores information related to material prices. Specifically, the memory unit 12 stores the unit price of materials for each of multiple material manufacturers. For example, this information is obtained by conducting a survey of suppliers (material manufacturers).

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

As shown in FIG. 2, the calculation unit 13 calculates the amount of each of multiple expense items based on the part information acquired by the acquisition unit 11, and calculates the cost of the part using the multiple calculated amounts. Here, the calculation unit 13 calculates the cost of the part by adding up the multiple calculated amounts. For example, the calculation unit 13 calculates the cost of the part for each of multiple suppliers.

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 material costs by multiplying the material unit price by the total material weight minus the scrap sales price. The calculation unit 13 also calculates processing costs by multiplying the molding machine rate by the total man-hours.

The calculation unit 13 calculates at least one of the multiple primary parameters using multiple secondary parameters. Here, the calculation unit 13 calculates the material weight meter using multiple secondary parameters, and calculates the molding machine rate using multiple secondary parameters. Specifically, the calculation unit 13 calculates the material weight meter using (product weight) + (SR weight) - (SR reuse weight) + (mold change/setup weight) + (defective weight) + (purged weight). The calculation unit 13 also calculates the molding machine rate using (direct labor costs) + (equipment costs) + (power costs) + (building costs) + (management costs).

The calculation unit 13 calculates at least one of the multiple secondary parameters using multiple tertiary parameters. Here, the calculation unit 13 calculates the SR weight using multiple tertiary parameters. Specifically, the calculation unit 13 calculates the SR weight by dividing the SR weight per shot by the number of shots taken.

The calculation unit 13 calculates the theoretical lowest price for each of the multiple expense items by using multiple primary parameters, etc., obtained from suppliers through questionnaires, 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.

As shown in FIG. 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.

The above describes the functional configuration of the cost calculation system 10 and other components related to the embodiment.

Figure 6 is a flowchart showing an example of the operation of the cost calculation system 10 of Figure 1 to calculate the cost of a part. An example of the operation of the cost calculation system 10 to calculate the cost of a part will be described with reference to Figure 6.

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

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.

The above describes an example of the operation of the cost calculation system 10 to calculate the cost of a part.

Figures 7 to 16 are first to tenth figures showing example screens displayed on the output device 22. Another example of the operation of the cost calculation system 10 will be described with reference to Figures 7 to 16.

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 user name, password, and language. Note that the login information does not necessarily have to be accepted. When a user enters login information using the input device 21, the entered login information is sent to the cost calculation system 10, and the cost calculation system 10 accepts the login information.

As shown in FIG. 8, when the cost calculation system 10 accepts login information, it displays a menu screen on the output device 22. Specifically, for example, the cost calculation system 10 displays a "New Parts Selection/Quote Request" icon, a "Quote Receipt" icon, a "Master Management" icon, and a "System Management" icon.

For example, when a 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, the cost calculation system 10 displays, for example, created projects and an icon 23 for adding a new project. When calculating new costs, the user clicks the icon 23 for adding a new project to create a new project, selects the new project, and clicks the "OK" icon.

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 forms the basis for the cost estimate, information on the "materials" of the part, information on the "processing" of the part, information on the "secondary processing" of the part, information on the "secondary materials" of the part, information on the "mold" used to manufacture the part, information on the "quantity proposal" of the part, and information on the "shipping inspection and packaging" of the part.

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. For example, if the required information has not been input, the cost calculation system 10 displays an error on the output device 22.

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.

When a user selects several 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.

When a 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 for 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.

For example, if the user clicks on the ">" next to the processing cost, the molding machine rate and labor hours, which are the primary parameters for calculating the processing cost, are displayed. Furthermore, if 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.

For example, the molding machine rate factor confirmation/change screen accepts changes to secondary parameters, etc. Specifically, for example, the cost calculation system 10 accepts changes to operating costs, changes to personnel, changes to TON numbers, and changes to the tie bar spacing/injection capacity list. When a user changes a secondary parameter, etc. and clicks the "Recalculate theoretical value" icon, the 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.

When the user clicks the "Confirm theoretical value" icon, the screen returns to the screen shown in Figure 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 Figure 8.

When the user clicks the "Receive quotation" icon, the cost calculation system 10 displays a list of received quotation screens, as shown in FIG. 15. Specifically, for example, the cost calculation system 10 displays the cost, etc. for each project for which a "request for quotation" has been issued.

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, etc. calculated by the cost calculation system 10 and actual values indicating the costs, etc. provided by the supplier. For example, a mark (see dotted circle) is displayed next to an expense item where 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.

When the user selects a supplier and clicks the "Output supplier selection report" icon, the report for that supplier will be output.

The above describes another example of the operation of the cost calculation system 10.

Figure 17 is an eleventh diagram showing an example of a screen displayed on the output device 22. Another example of the operation of the cost calculation system 10 will be described with reference to Figure 17.

As shown in FIG. 17, for example, the acquisition unit 11 acquires CAD data and obtains 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. In this case, the CAD data is 3D data.

The cost calculation system 10 further includes an extraction unit that references the CAD data acquired by the acquisition unit 11 and extracts parts of the part that are associated with any of multiple expense items. For example, the extraction unit is realized by a processor or the like, and is provided in a single housing together with the acquisition unit 11, etc.

For example, each of multiple expense items is linked in advance to the shape of the part, and the extraction unit extracts and displays the parts of the part that are linked to the expense item selected by the user. Also, for example, CAD data includes information indicating the machined parts of the part, and when the user selects a processing cost, the extraction unit extracts and displays that part as a part associated with the processing cost.

Specifically, for example, the CAD data includes information indicating that the outer shape of the part is formed by cutting, and that the curved parts of the part are formed by bending.

For example, if the first process is a cutting process and the user clicks on the "Processing Cost" text for the first process, the extraction unit will extract the outer shape of the part, and the outer shape of the part will be highlighted (for example, shown with a bold line) as the part associated with that processing cost.

For example, if the second process is a bending process and the user clicks on the "Processing Cost" text for the second process, the extraction unit will extract the bending portion of the part, and the bending portion of the part will be highlighted (for example, shown with a bold line) as the part associated with that processing cost.

The above describes an example of another operation of the cost calculation system 10.

Figure 18 is a twelfth diagram showing an example screen displayed on the output device 22. Referring to Figure 18, another example of the operation of the cost calculation system 10 will be described.

As shown in FIG. 18, for example, when the acquisition unit 11 reads CAD data, the cost calculation system 10 indicates design issues for the part. For example, the cost calculation system 10 indicates design issues for the part by representing the design issues with a thick line.

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 in bold and display a message indicating that there is a risk of tearing. Furthermore, for example, the cost calculation system 10 may display a list of multiple parts with a similar shape to the part in question, and display information about a part selected by the user from the list. This makes it possible to find out how similar issues were resolved in parts manufactured in the past.

The above describes another example of the operation of the cost calculation system 10.

Figures 19 to 21 are thirteenth to fifteenth figures showing example screens displayed on the output device 22. Another example of the operation of the cost calculation system 10 will be described with reference to Figures 19 to 21.

As shown in FIG. 19, for example, the cost calculation system 10 displays an input screen that accepts input of part information such as the part's manufacturing region, part size, and secondary processing of the part. When the user inputs part information and clicks the "Search with these conditions" icon, the cost calculation system 10 searches for suppliers that can manufacture the part related to the input part information.

As shown in FIG. 20, for example, the cost calculation system 10 displays one or more suppliers that can manufacture the part related to the input part information. For example, the cost calculation system 10 displays, for each of 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."

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

The above describes another example of the operation of the cost calculation system 10.

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 multiple 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 multiple expense items using multiple primary parameters.

As a result, the calculation unit 13 calculates the amount of at least one of the multiple expense items using multiple primary parameters, allowing for more accurate calculation of the amount of at least one of the multiple expense items, and therefore more accurate calculation of the cost of the part.

Furthermore, in the cost calculation system 10 according to the embodiment, the calculation unit 13 calculates the theoretical lowest cost price for the part.

This allows for more accurate calculation of the theoretical lowest cost of a part.

Furthermore, in the cost calculation system 10 according to the embodiment, the calculation unit 13 calculates at least one of the multiple primary parameters using multiple secondary parameters.

This allows at least one of the multiple primary parameters to be calculated more accurately, and the cost of the part to be calculated even more accurately.

Furthermore, in the cost calculation system 10 according to the embodiment, the multiple expense items include processing costs, and the multiple primary parameters used to calculate 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 (total man-hours).

This allows for more accurate calculation of processing costs and more accurate calculation of part costs.

In addition, in the cost calculation system 10 according to the embodiment, the multiple secondary parameters used to calculate 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.

This allows for more accurate calculation of the cost per unit time required to process a part (molding machine rate), and more accurate calculation of the cost price of the part.

Furthermore, in the cost calculation system 10 according to the embodiment, the acquisition unit 11 acquires CAD data for the part and acquires part information from the CAD data.

This allows for more accurate acquisition of part information, enabling more accurate calculation of part costs.

In addition, the cost calculation system 10 according to the embodiment further includes an extraction unit that references CAD data and extracts parts of the part that are associated with any of multiple expense items.
