Summary of the Invention

Problems to be Solved by the Invention

[0004] The component standardization support device of Patent Document 1 only selects components with a large past production volume as components suitable for standardized components, and does not evaluate whether the selected components are suitable for standardized components from objective viewpoints such as quality, supply stability, and cost. Therefore, for example, there is a possibility that components that have been habitually used for many years despite being of low quality or high price, or components with low supply stability, may be selected. For this reason, it is required to objectively select components suitable for standard components without being restricted by past achievements. This also applies to the standardization of materials, raw materials, etc. as well as components.

The attribute data acquisition unit acquires data indicating the attributes of a plurality of standardization targets that make up each of the plurality of products. The quality data acquisition unit acquires quality data indicating the quality of the standardization targets. The delivery date data acquisition unit acquires delivery date data indicating the delivery dates of the standardization targets. The quality loss cost acquisition unit acquires a quality loss cost obtained by converting the loss due to the quality of the standardization targets into cost based on the quality data. The delivery date loss cost acquisition unit acquires a delivery date loss cost obtained by converting the loss due to the delivery dates of the standardization targets into cost based on the delivery date data. The standardization recommendation selection unit selects a standardization recommendation that recommends treating as a standard from among the plurality of standardization targets based on the unit price, quality loss cost, and delivery date loss cost of the standardization targets.

Effect of the Invention

[0007] According to the present disclosure, a standardization recommendation that recommends treating as a standard is selected based on the unit price, quality loss cost, and delivery date loss cost of the parts. Therefore, it is possible to select a recommendation for treating as a standard from an objective perspective and support the promotion of standardization.

Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of a component standardization support device, a component standardization support method, and a component standardization support program according to the present disclosure will be described with reference to the drawings.

[0010] [Embodiment 1] With reference to FIG. 1, an overview of a component standardization support system 100 including a component standardization support device 10 will be described. The component standardization support system 100 includes a component standardization support device 10 that selects standardized recommended components recommended to be treated as standard components from among a plurality of components, a design department server DS managed by a design department that designs product PRs, a material management department server MS managed by a material management department that manages components, which are materials necessary for producing product PRs, and a production management department server PS managed by a production management department that manages the production of product PRs. Note that components are an example of objects to be standardized.

[0011] The design department server DS stores the parts list data D1. The parts list data D1 includes data such as the name of the product PR, the name of the series S of the product PR, the names of each of the plurality of first parts P1 to nth parts Pn included in the product PR, and the attributes of each of the plurality of parts. In this embodiment, the "name" is a general term for identification information for identifying the object. Specifically, in this embodiment, the name includes attribute information to the extent that the specifications of the part can be specified.

[0012] The first part P1 to the nth part Pn are all the parts necessary for manufacturing all the products PR handled by the parts standardization support device 10. Each product PR includes at least one of the first part P1 to the nth part Pn. Hereinafter, the first part P1, the second part P2, the third part P3 ··· the nth part Pn may be collectively referred to as "part P".

[0013] The parts list data D1 is updated by the design staff DU during the development of the product PR and during the improvement of the product PR. The product PR is an air conditioner, a refrigerator, etc. The part P is an electronic part, a mechanical part, etc. Electronic parts are, for example, capacitors, diodes, processors, motors, etc., and mechanical parts are, for example, springs, bolts, heat insulators, etc. The parts managed by the parts list data D1 are arbitrary.

[0014] In addition, when a certain part P is recognized as a standard part by the person in charge of promoting standardization, the standard part flag is set in the parts list data D1. The standard part flag is information indicating whether the part P is a standard part. In the example shown in FIG. 1, the fourth part P4 with an asterisk "*" added corresponds to the part P recognized as a standard part. The standard parts are pre-recognized by the person in charge of promotion in consideration of aspects such as the cost and productivity of the part P. The person in charge of promotion is composed of, for example, the design staff DU, the material management staff MU, and the production management staff PU.

[0015] The material management department server MS stores the material department management data D2 designed for the management of the component P. The material department management data D2 includes the unit price data G2 indicating the unit price of the component P and the quality data G3 indicating the quality of the component P. The material department management data D2 is registered and updated by the material management person in charge MU.

[0016] The production management department server PS manages the production department management data D3 including the delivery date data G4 indicating the delivery date of the component P. The production department management data D3 is registered and updated by the production management person in charge PU.

[0017] The component standardization support device 10 acquires the data separately managed by the design department server DS, the material management department server MS, and the production management department server PS, and selects the component P that is recommended to be treated as a standard component based on the data acquired from each server. Hereinafter, the component P that is recommended to be treated as a standard component is referred to as a "standardization recommended component".

[0018] The component standardization support device 10 acquires the data indicating the attributes of the plurality of components P that make up each of the plurality of products PR. Specifically, the component standardization support device 10 acquires the data G1 indicating the name including the attribute information of the non-standardized components other than the standard components in the component list data D1. Hereinafter, the data G1 is referred to as "product-specific component data G1". The product-specific component data G1 is input to the component standardization support device 10 by, for example, the design person in charge DU.

[0019] The component standardization support device 10 acquires the unit price data G2 indicating the unit price of each component P and the quality data G3 indicating the quality of each component P from the material department management data D2. The unit price data G2 and the quality data G3 are input to the component standardization support device 10 by, for example, the material management person in charge MU. The component standardization support device 10 acquires the quality loss cost obtained by converting the loss due to quality into cost based on the quality data G3. The method for acquiring the quality loss cost will be described later.

[0020] The component standardization support device 10 acquires delivery date data G4 indicating the delivery date of component P from the production department management data D3. The delivery date data G4 is input into the component standardization support device 10 by, for example, the production management staff PU. The component standardization support device 10 acquires a delivery loss cost obtained by converting the loss due to the delivery date into cost based on the delivery date data G4. The method for acquiring the delivery loss cost will be described later.

[0021] When designing a new product PR, the design staff DU operates the component standardization support device 10 to specify a product PR similar to the new product PR from among the product PRs indicated by the product-specific component data G1. Similarly, when making a design change to an existing product PR, the design staff DU specifies a product PR similar to the product PR to be changed in design from among the product PRs indicated by the product-specific component data G1.

[0022] The component standardization support device 10 groups the components P that are in a corresponding relationship with each other among the components P that make up the product PR specified by the design staff DU into one group. Specifically, the component standardization support device 10 groups each component P by regarding it as the same type of component P based on at least one of the attributes of each component P, particularly the specifications and functions of each component P. The component standardization support device 10 presents the components P regarded as the same type as candidate components for standardization to the design staff DU. Specifically, when the design staff DU specifies a certain type of component P, the component standardization support device 10 selects one component P with the minimum total cost obtained based on the unit price, quality loss cost, and delivery loss cost from among the candidate components for standardization belonging to the specified type of component P. The component standardization support device 10 presents the selected component P as a recommended component for standardization. The design staff DU sequentially selects the components P to be used in the new product PR or the product PR to be changed in design with reference to the components P presented by the component standardization support device 10 and the pre-approved standard components, and proceeds with the design.

[0023] When the design is completed, the designer DU adds and registers the data of the designed product PR and the components P that make up the product PR to the parts list data D1. As a result, the parts data G1 by product is updated. Thereafter, the above process is repeated.

[0024] Hereinafter, a method in which standardized recommended parts are selected and presented will be described with reference to the configuration of the parts standardization support device 10.

[0025] As shown in FIG. 2, the parts standardization support device 10 includes an operation unit 11 that receives an operation by a user, a display unit 12 that displays an image, a communication unit 13 that transmits and receives various data, a processor 15 that executes various processes, a main storage device 16 used as a work area for the processor 15, and an auxiliary storage device 17 that stores various data.

[0026] The operation unit 11 receives an operation by the user and outputs a signal corresponding to the operation to the processor 15. The operation unit 11 includes a touch sensor, a keyboard, a mouse, and the like.

[0027] The display unit 12 displays an image based on a signal output from the processor 15. The display unit 12 includes, for example, a liquid crystal display, an organic EL (Organic Electro Luminescence) display, and the like.

[0028] The communication unit 13 transmits and receives data according to the control by the processor 15. The communication unit 13 includes a communication device that performs communication corresponding to communication standards such as Ethernet (registered trademark) and USB (Universal Serial Bus).

[0029] The processor 15 includes an MPU (Micro processing Unit), a CPU (Central Processing Unit), and the like.

[0030] The main storage device 16 includes a RAM (Random Access Memory).

[0031] The auxiliary storage device 17 includes non-volatile memories such as a flash memory, an HDD (Hard Disk Drive), and an SDD (Solid State Drive).

[0032] As shown in FIG. 3, the auxiliary storage device 17 includes a data storage unit 170 that stores data necessary for presenting standardized recommended components. Note that the user can view and edit the data stored in the data storage unit 170.

[0033] The data storage unit 170 includes a product-specific component data storage unit 171 that stores data indicating the attributes of the component P, and a component cost data storage unit 172 that stores data indicating the cost of each component P.

[0034] As shown in FIG. 4, the product-specific component data storage unit 171 stores by associating the series S and the components P other than the standard components for each product PR described with reference to FIG. 1. Specifically, the product-specific component data storage unit 171 associates and stores data indicating an ID171a for identifying a record, a product model number 171b indicating the model number of the product PR, a series name 171c indicating the name of the series S, a component name 171d indicating the name of the component P other than the standard components included in the product PR, and a drawing number 171e indicating the drawing number of the design drawing representing the component P. Note that hereinafter, the drawing number of the design drawing representing the component P is referred to as the "drawing number of the component P".

[0035] The model number is composed of a character string that can uniquely identify the product PR. The model number is composed according to a predetermined rule based on the number of years of sales, specifications, etc. The user can sort the data stored in the product-specific component data storage unit 171 in the order of the number of years of sales, specifications, etc. by arranging the data indicating the product model number 171b in alphabetical order. In the example shown in FIG. 4, the model numbers of the product PRs with similar specifications have the same character string from the beginning to a predetermined position in advance. For example, the product PRs starting with the model number "AAA" are similar to each other. Also, the end of the model number is different for each series. Further, the four-digit number after the hyphen in the model number indicates the number of years of sales.

[0036] The series name is a name indicating a series of series S developed based on a certain concept, and is composed of a character string that can uniquely identify series S. In the example shown in FIG. 4, the data indicating from ID "11" to ID "13" are the component P constituting the product PR with the series name "Series A" and the data indicating the drawing number of the component P. Similarly, ID "21", ID "22", and ID "23" are the component P constituting the product PR with the series name "Series B" and the data indicating the drawing number of the component P, and ID "31", ID "32", and ID "33" are the component P constituting the product PR with the series name "Series C" and the data indicating the drawing number of the component P. Note that in this embodiment, Series A, Series B, Series C, and Series D are assumed to be similar products PR.

[0037] The part name is composed of a character string representing the name of the component P constituting the product PR, such as a spring or a bolt, and the attribute of the component P. Each component P includes a plurality of types with different specifications such as shape, dimension, performance, and manufacturer. Among the components P of different types, there are also components P that are similar to each other to the extent that their specifications can be regarded as the same. The use of such components P causes an increase in the number of types of components P handled by the production management department.

[0038] For example, the first component P1 shown in FIG. 4 is a "bolt with a diameter of 6 mm", and the second component P2 is a "bolt with a diameter of 15 mm". The expression method of the name of the component P is unified by factory unit and department unit, and the component P can be specified within a certain range by the name of the component P.

[0039] The drawing number is composed of a character string that can uniquely identify the design drawing representing the component P. The drawing number corresponds to the identification number of the component P. Even if the names of the components P are the same, there are those with different types, and in that case, the drawing numbers of those components P are different. Specifically, the drawing number of the design drawing of the component name "First Component P1" with ID "11" shown in FIG. 4 is "A0000A01". On the other hand, the drawing number of the design drawing of the component name "First Component P1" with ID "21" is "A0000A02". That is, although the component names of ID "11" and ID "21" are the same, their types are different.

[0040] As shown in FIG. 3, the component cost data storage unit 172 stores data indicating the cost of each component P for each purchase source of the component P. The data stored in the component cost data storage unit 172 is based on the unit price data G2 and the quality data G3 shown in FIG. 1.

[0041] Specifically, the component cost data storage unit 172 associates and stores data indicating a purchase source name 172a indicating the name of the purchase source of the component P, a series name 172b indicating the name of the series S of the product PR in which the component P is used, a drawing number 172c of the component P, a component name 172d indicating the name of the component P, a delivery date 172e indicating the number of days required from placing an order for the component P with the purchase source until delivery, an inspection pass rate 172f indicating the pass rate of the quality inspection of the component P, a unit price 172g indicating the unit price of the component P, a delivery date loss cost 172h indicating the delivery date loss cost obtained by converting the loss due to the delivery date of the component P into cost, and a quality loss cost 172j indicating the quality loss cost obtained by converting the loss due to the quality of the component P into cost. The pass rate of the quality inspection of the component P is obtained, for example, by dividing the quantity of the component P determined to be qualified in the inspection carried out at the factory after the delivery of the component P by the total number of inspected components P.

[0042] The series name 172b stores data indicating the series name 171c of the product-specific component data storage unit 171 described with reference to FIG. 4. Similarly, the component name 172d stores data indicating the component name 171d of the product-specific component data storage unit 171, and the drawing number 172c stores data indicating the drawing number 171e of the product-specific component data storage unit 171.

[0043] The purchase source name 172a, the delivery date 172e, the inspection pass rate 172f, and the unit price 172g store data input by the materials management staff MU operating the operation unit 11 with reference to FIG. 1. Thereby, the component standardization support device 10 acquires the unit price data G2 and the quality data G3 described with reference to FIG. 1.

[0044] The materials management staff member MU adds the data stored in the supplier name 172a, delivery date 172e, inspection pass rate 172f, and unit price 172g each time a new product PR is developed and the types of parts P increase. Also, the materials management staff member MU periodically updates the data stored in the supplier name 172a, delivery date 172e, inspection pass rate 172f, and unit price 172g. The data update may be performed at the timing of confirming the effect of improvement activities, for example, once a year.

[0045] The delivery delay cost 172h stores data indicating the delivery delay cost, which is a value obtained by converting the loss due to the delivery date into cost based on the data stored in the delivery date 172e. The delivery delay cost is calculated and stored in the delivery delay cost 172h when data is stored in the delivery date 172e.

[0046] The delivery delay cost is a cost based on the expenses incurred for stocking part P in anticipation of the delivery date. The delivery delay cost is obtained, for example, by multiplying the number of days from the order of part P to its delivery by the labor cost of the inventory management operator. Specifically, if the delivery date of part P is, for example, 7 days and the labor cost of the inventory management operator is, for example, 100 yen per day, the delivery delay cost is obtained by 7 × 100. Note that the data indicating the labor cost of the inventory management operator is pre-stored in the data storage unit 170.

[0047] The quality loss cost 172j stores data indicating the quality loss cost, which is a value obtained by converting the loss due to quality into cost based on the data stored in the inspection pass rate 172f. The quality loss cost is calculated and stored in the quality loss cost 172j when data is stored in the inspection pass rate 172f.

[0048] The quality loss cost is a cost based on the return cost, which is the total value of the cost required to return the part P determined to be defective in inspection to the supplier, the cost required for return communication, and the cost required for improvement guidance. The return cost is obtained, for example, by multiplying the return man-hours required for return, return communication, and improvement guidance by the labor cost of the return workers involved in those operations. For example, when the return man-hours are 0.5 days and the labor cost of the return workers is 100 yen per day, the return cost is obtained by 100 × 0.5.

[0049] The quality loss cost is obtained by multiplying the return cost by the inspection nonconformance rate. The inspection nonconformance rate is obtained by subtracting the value of the inspection pass rate 172f shown in FIG. 5 from 100. Therefore, when the inspection pass rate is 96%, the quality loss cost is obtained by 100 × 0.5 × (100 - 96) × 100. Note that the data indicating the labor cost of the return workers is stored in advance in the data storage unit 170. Also, the data indicating the return man-hours is input to the component standardization support device 10 by the material management person in charge MU.

[0050] The processor 15 shown in FIG. 2 functions as a product-by-product component data acquisition unit 151 that acquires product-by-product component data G1 as shown in FIG. 3, a unit price and quality data acquisition unit 152 that acquires unit price data G2 and quality data G3, a delivery date data acquisition unit 153 that acquires delivery date data G4, a quality loss cost acquisition unit 154 that acquires the quality loss cost based on the quality data G3, a delivery date loss cost acquisition unit 155 that acquires the delivery date loss cost based on the delivery date data G4, a standardized candidate component presentation unit 156 that presents the standardized candidate components to the user, and a standardized recommended component selection unit 157 that selects the standardized recommended components by executing the component standardization support program PG stored in the data storage unit 170. Note that the processor 15 uses the operation unit 11, the display unit 12, the communication unit 13, the main storage device 16, and the auxiliary storage device 17 shown in FIG. 2 as resources.

[0051] The product-specific parts data acquisition unit 151 executes a product-specific parts data acquisition process for acquiring product-specific parts data G1 from the parts list data D1 shown in FIG. 1. In the product-specific parts data acquisition process, the product-specific parts data acquisition unit 151 stores the acquired product-specific parts data G1 in the product-specific parts data storage unit 171 shown in FIG. 4. The product-specific parts data acquisition unit 151 acquires the product-specific parts data G1 each time the parts list data D1 is updated.

[0052] The unit price and quality data acquisition unit 152 shown in FIG. 3 executes a unit price acquisition process for acquiring unit price data G2. Further, the unit price and quality data acquisition unit 152 executes a quality data acquisition process for acquiring quality data G3. The unit price acquisition process and the quality data acquisition process are executed in response to an operation on the operation unit 11 of the materials management person MU. Specifically, the unit price and quality data acquisition unit 152 stores the acquired unit price data G2 and quality data G3 in the unit price 172g and the inspection pass rate 172f of the parts cost data storage unit 172 described with reference to FIG. 5. Further, the unit price and quality data acquisition unit 152 acquires data indicating the purchase source of the part P. The unit price and quality data acquisition unit 152 stores the acquired data indicating the purchase source of the part P in the purchase source name 172a of the parts cost data storage unit 172.

[0053] The unit price and quality data acquisition unit 152 acquires the unit price data G2, the quality data G3, etc. by, for example, causing the unit price and quality data input screen 121 shown in FIG. 6 to be displayed on the display unit 12. The unit price and quality data acquisition unit 152 causes the unit price and quality data input screen 121 to be displayed on the display unit 12 in response to an operation on the operation unit 11 of the materials management person MU.

[0054] The unit price and quality data input screen 121 includes an item column 121a showing the items of each field, a series name display column 121b for displaying the name of the series S, a part name display column 121c for displaying the name of the part P, and a drawing number display column 121d for displaying the drawing number of the part P.

[0055] In addition, the unit price and quality data input screen 121 includes a supplier input field 121e for receiving input of data indicating the name of the supplier of part P, a part unit price input field 121f for receiving input of data indicating the unit price of part P, and an inspection pass rate input field 121g for receiving input of data indicating the pass rate of the inspection of part P.

[0056] In the supplier input field 121e, data indicating the supplier of part P displayed in the corresponding part name display field 121c is input by the materials management staff MU. Similarly, in the part unit price input field 121f and the inspection pass rate input field 121g, data indicating the unit price of part P and data indicating the inspection pass rate displayed in the corresponding part name display field 121c are respectively input by the materials management staff MU.

[0057] The data input in the supplier input field 121e is stored in the supplier name 172a of the part cost data storage unit 172 described with reference to FIG. 5. Similarly, the data input in the part unit price input field 121f and the inspection pass rate input field 121g are respectively stored in the unit price 172g and the inspection pass rate 172f of the part cost data storage unit 172.

[0058] When data indicating quality is stored in the part cost data storage unit 172, the quality loss cost acquisition unit 154 shown in FIG. 3 executes a quality loss cost acquisition process for acquiring the quality loss cost. Specifically, when data indicating the inspection result is stored in the inspection pass rate 172f of the part cost data storage unit 172 as data indicating quality, the quality loss cost acquisition unit 154 obtains the quality loss cost based on the data stored in the inspection pass rate 172f. The data indicating the obtained quality loss cost is stored in the quality loss cost 172j of the part cost data storage unit 172 described with reference to FIG. 5.

[0059] The delivery date data acquisition unit 153 shown in FIG. 3 executes a delivery date data acquisition process for acquiring the delivery date data G4. Specifically, the delivery date data acquisition unit 153 stores the acquired delivery date data G4 in the delivery date 172e of the part cost data storage unit 172 described with reference to FIG. 5.

[0060] The delivery date data acquisition unit 153 acquires the delivery date data G4, for example, by causing the delivery date data input screen 122 shown in FIG. 7 to be displayed on the display unit 12. The delivery date data acquisition unit 153 causes the delivery date data input screen 122 to be displayed on the display unit 12 in response to an operation on the operation unit 11 by the production management person in charge PU.

[0061] The delivery date data input screen 122 includes an item column 122a indicating the items of each field, a series name display column 122b for displaying the name of the series S, a part name display column 122c for displaying the name of the part P, a drawing number display column 122d for displaying the drawing number of the part P, and a supplier display column 122e for displaying the name of the supplier of the part P.

[0062] In addition, the delivery date data input screen 122 includes a delivery date input column 122f for accepting input of data indicating the delivery date of the part P. In the delivery date input column 122f, data indicating the delivery date of the part P displayed in the corresponding part name display column 122c is input by the production management person in charge PU. The input data is stored in the delivery date 172e of the part cost data storage unit 172 described with reference to FIG. 5.

[0063] When data indicating the delivery date is stored in the part cost data storage unit 172, the delivery date loss cost acquisition unit 155 shown in FIG. 3 executes a delivery date loss cost acquisition process for acquiring the delivery date loss cost. Specifically, when data indicating the delivery date is stored in the delivery date 172e of the part cost data storage unit 172, the delivery date loss cost acquisition unit 155 obtains the delivery date loss cost based on the data stored in the delivery date 172e. The data indicating the obtained delivery date loss cost is stored in the delivery date loss cost 172h of the part cost data storage unit 172 described with reference to FIG. 5.

[0064] Based on the data stored in the product-specific part data storage unit 171 described with reference to FIG. 4, the standardization candidate part presentation unit 156 shown in FIG. 3 presents the user with standardization candidate parts from among a plurality of parts P. The standardization candidate parts are selected from among the parts P used in the products PR that are similar to each other.

[0065] When selecting standardized candidate parts, the standardized candidate part presentation unit 156 extracts data indicating parts P that constitute product PRs similar to each other from the product-specific part data storage unit 171. The designation of similar product PRs is made by the user.

[0066] The standardized candidate part presentation unit 156 accepts the designation of similar product PRs, for example, by causing the display unit 12 to display a similar product designation screen 123 as shown in FIG. 8.

[0067] The similar product designation screen 123 includes a product model number input field 123a that accepts the input of the product model number of the product PR as a field for designating the conditions of the product PR to be extracted from the product-specific part data storage unit 171, a sales year input field 123b that accepts the input of the sales year of the product PR, a specification designation column 123c for designating the type of specification of the product PR, and a specification condition input column 123d for inputting the conditions of the designated specification.

[0068] The product model number input field 123a accepts the input of a character or character string designating the product model number. When the user inputs, for example, "AAA", product PRs whose product model numbers include "AAA" are extracted from the product-specific part data storage unit 171.

[0069] In the sales year input field 123b, character strings indicating sales years such as "2021" and "2020" are displayed in a pull-down format. When the user selects, for example, "2020", product PRs sold in 2020 are extracted from the product-specific part data storage unit 171.

[0070] In the specification designation field 123c, strings indicating types for each specification of the product PR, such as capacity units, ability units, etc., are displayed in a pull-down format. The specification data displayed in the specification designation field 123c is obtained, for example, from the parts list data D1 shown in FIG. 1. The user can select one type from the types of specifications displayed in the specification designation field 123c and input a character or a string specifying the conditions of the type of specification selected in the specification designation field 123c into the specification condition input field 123d. When the user selects, for example, "capacity unit" in the specification designation field 123c and inputs a string indicating "1 kW or more" as the condition of the capacity unit into the specification condition input field 123d, the product PR with a capacity unit of 1 kW or more is extracted from the product-specific parts data storage unit 171.

[0071] The standardized candidate part presentation unit 156 shown in FIG. 3 executes a standardized candidate part presentation process for presenting standardized candidate parts to the user. Specifically, in the similar product designation screen 123 described with reference to FIG. 8, when at least one condition is specified from the product model number, the number of years of sales, and the specifications, the standardized candidate part presentation unit 156 extracts data indicating the product PR that matches the specified conditions from the product-specific parts data storage unit 171 described with reference to FIG. 4.

[0072] The standardized candidate part presentation unit 156 compares the data indicated by the drawing numbers of the parts P indicated by the data extracted from the product-specific parts data storage unit 171. The standardized candidate part presentation unit 156 compares the data indicated by the drawing numbers of the same type of part P among a plurality of product PRs. The same type of part P refers to the part P with the same part name 171d described with reference to FIG. 4. That is, the standardized candidate part presentation unit 156 groups the parts P with the same part name 171d as the same type of part P. In the example shown in FIG. 4, the part name "first part P1" in the series names "series A", "series B", "series C", and "series D" corresponds to the same type of part P.

[0073] The standardized candidate part presentation unit 156 compares, for example, the drawing number "A0000A01" of the part name "First Part P1" of the series name "Series A" with the ID "11" and the drawing number "A0000A02" of the part name "First Part P1" of the series name "Series B" with the ID "21", and determines whether the data indicated by the drawing numbers is different. Similarly hereinafter, among the plurality of extracted product PRs, the data indicated by the drawing numbers of the same type of part P is compared to determine whether the data indicated by the drawing numbers is different.

[0074] When the data indicating the drawing numbers of the same type of part P is different among the plurality of product PRs, the standardized candidate part presentation unit 156 determines that those parts P are of different types, and presents the different types of parts P to the user as standardized candidate parts.

[0075] The standardized candidate part presentation unit 156 presents the standardized candidate part PK to the user by, for example, causing the display unit 12 to display the part display screen 124 for each similar product shown in FIG. 9.

[0076] The part display screen 124 for each similar product includes a series name item column 124a that displays the name of the series S of the product PR as an item, a part name item column 124b that displays the name of the part P as an item, and a drawing number display column 124c that displays the drawing number of each part P of each series S.

[0077] In the series name item column 124a, the name of the series S indicated by the data stored in the series name 171c of the product-by-part data storage unit 171 is displayed. The series name item column 124a is provided along the column direction by the number of extracted series S, and the names of different series S are displayed in each column.

[0078] In the part name item column 124b, the name of the part P indicated by the data stored in the part name 171d of the product-by-part data storage unit 171 is displayed. The part name item column 124b is provided along the row direction by the number of parts P that make up the product PR of a certain series S, and the names of different parts P are displayed in each row. In the example shown in FIG. 9, the parts P are classified and displayed as mechanical parts and electronic parts.

[0079] In the drawing number display column 124c, the drawing number of the part P corresponding to the part name displayed in the same column as the product PR of the series S displayed in the same row is displayed.

[0080] The standardized candidate part presentation unit 156 presents to the user the part P of at least one different type among a plurality of products PR as the standardized candidate part PK.

[0081] Specifically, the standardized candidate part presentation unit 156 presents the standardized candidate part PK to the user by displaying the parts P of different types among the plurality of products PR in a form that is easy for the user to identify.

[0082] The standardized candidate part presentation unit 156 presents the standardized candidate part PK to the user by displaying the backgrounds of the drawing number display columns 124c for displaying the parts P of different types in different colors. Thereby, the user can easily recognize the standardized candidate part PK. Note that the standardized candidate part PK may be displayed in a form that is easy for the user to identify. For example, the characters of the drawing numbers of the standardized candidate parts PK may be displayed in different colors. Note that the parts P displayed in the drawing number display columns 124c of the same color indicate that they are of the same type as each other.

[0083] In the example shown in FIG. 9, the drawing number of the part name "First part P1" of the series name "Series A" is "A0000A01", the drawing number of the part name "First part P1" of the series name "Series B" is "A0000A02", the drawing number of the part name "First part P1" of the series name "Series C" is "A0000A03", and the drawing number of the part name "First part P1" of the series name "Series D" is "A0000A04". Therefore, since the types of the first part P1 used among the series names "Series A", "Series B", "Series C", and "Series D" are different, the drawing number display columns 124c for displaying the drawing numbers of the first part P1 of each series shown in FIG. 9 are displayed in different colors.

[0084] Also, the drawing number of the part "Second Part P2" for the series names "Series A" and "Series B" is "A0000B01", and the drawing number of the part "Second Part P2" for the series names "Series C" and "Series D" is "A0000B02". That is, the types of the second part P2 used between the series names "Series A" and "Series B" and the series names "Series C" and "Series D" are different, and the drawing number display column 124c that displays the drawing numbers of the second part P2 for the series names "Series A" and "Series B" and the series names "Series C" and "Series D" is displayed in different colors respectively.

[0085] As a result, the user can recognize that among the first parts P1, the parts P used in each of the series names "Series A", "Series B", "Series C", and "Series D" are the standardized candidate parts PK. Similarly, the user can recognize that among the second parts P2, the two parts P used in the series names "Series A" and "Series B" and the parts P used in the series names "Series C" and "Series D" are the standardized candidate parts PK.

[0086] The standardized recommended part selection unit 157 executes a standardized recommended part selection process of selecting, as standardized recommended parts, the parts P recommended to be treated as standards from among a plurality of parts P. Specifically, the standardized recommended part selection unit 157 selects standardized recommended parts from among the standardized candidate parts PK presented in FIG. 9. The standardized recommended part selection unit 157 selects only one standardized recommended part.

[0087] The standardized recommended part selection unit 157 selects standardized recommended parts from among the standardized candidate parts PK based on the respective values indicated by the data indicating the unit price 172g stored in the part cost data storage unit 172 described with reference to FIG. 5, the data indicating the delivery delay cost 172h, and the data indicating the quality loss cost 172j.

[0088] In the present embodiment, the standardized recommended component selection unit 157 selects, as the standardized recommended component, a component P for which the total cost, which is the sum of the values indicated by the data indicating the unit price of 172 g, the data indicating the delivery delay cost of 172 h, and the data indicating the quality loss cost of 172 j, is minimized.

[0089] The standardized recommended component selection unit 157 presents the selected standardized recommended component PP to the user, for example, by causing the display unit 12 to display a standardized recommended component presentation screen 125 shown in FIG. 10. The standardized recommended component presentation screen 125 is displayed on the display unit 12 when the user selects the component name displayed in the component name item column 124b described with reference to FIG. 9, for example.

[0090] The standardized recommended component presentation screen 125 includes a series name item column 125a that displays the name of the series S as an item, a component attribute item column 125b that displays the attributes of the component P as an item, a changed drawing number display column 125c that displays the drawing number of the changed component P for each component P of each series S, a drawing number display column 125d of the component P before change that displays the drawing number of the component P before change for each component P of each series S, a unit price display column 125e that displays the unit price of the component P before change, a delivery delay cost display column 125f that displays the delivery delay cost of the component P before change, and a quality loss cost display column 125g that displays the quality loss cost of the component P before change.

[0091] For example, in the example shown in FIG. 10, among the first components P1 used in similar products PR of series A, series B, series C, and series D, the total cost of the first component P1 used in series A is the lowest. Therefore, the standardized recommended component selection unit 157 selects the first component P1 used in series A as the standardized recommended component PP.

[0092] The standardized recommended component selection unit 157 presents the standardized recommended component PP to the user by displaying the backgrounds of the changed drawing number display column 125c and the previous drawing number display column 125d that display the standardized recommended component PP in a color different from the changed drawing number display column 125c and the previous drawing number display column 125d that display components P other than the standardized recommended component PP. Note that the standardized recommended component PP may be displayed in a form that is easy for the user to identify. For example, the characters of the drawing numbers of the standardized recommended component PP may be displayed in different colors. The user can easily recognize the standardized recommended component PP by referring to the changed drawing number display column 125c and the previous drawing number display column 125d.

[0093] Hereinafter, with reference to FIG. 11, the component standardization support process executed by the standardized candidate component presentation unit 156 and the standardized recommended component selection unit 157 will be described.

[0094] The component standardization support process is started, for example, when the design person in charge DU operates the operation unit 11 when selecting the component P when developing a new product PR.

[0095] When the component standardization support process is started, the standardized candidate component presentation unit 156 causes the display unit 12 to display the similar product designation screen 123 described with reference to FIG. 8 (step S101).

[0096] Next, the standardized candidate part presentation unit 156 receives the designation of a similar product PR by the person in charge of design DU (step S103). Specifically, as a condition for the person in charge of design DU to designate a similar product PR, the person in charge of design DU inputs a character string indicating the model number of the product PR, for example, "A0000", into the product model number input field 123a. The standardized candidate part presentation unit 156 extracts data indicating the product PR that meets the designated conditions from the product-specific part data storage unit 171 as similar product PRs (step S105). In this embodiment, for product PRs with similar specifications, the character strings from the beginning to a predetermined position are unified. Therefore, the person in charge of design DU can specify the conditions for extraction as product PRs with similar specifications by designating the character string from the beginning to a predetermined position of the model number of the product PR.

[0097] When the standardized candidate part presentation unit 156 extracts data indicating similar product PRs from the product-specific part data storage unit 171, it causes the display unit 12 to display the similar product-specific part display screen 124 described with reference to FIG. 9 (step S107), and presents the standardized candidate part PK to the person in charge of design DU (step S109). The person in charge of design DU can recognize the part P corresponding to the figure number in the figure number display column 124c displayed in a different color among the figure number display columns 124c displayed on the similar product-specific part display screen 124 as the standardized candidate part PK.

[0098] When the person in charge of design DU recognizes the standardized candidate part PK, in order to select the standardized recommended part PP, the person in charge of design DU designates the part name item column 124b that displays the part P that is the basis for selecting the standardized recommended part PP. For example, the person in charge of design DU clicks on "First part P1" displayed in the part name item column 124b of FIG. 9 to designate the part P that is the basis for selecting the standardized recommended part PP.

[0099] When the standardized recommended part selection unit 157 receives the designation of the part P that is the basis for selecting the standardized recommended part PP (step S111), it calculates the total cost of the designated part P (step S113). In the example shown in FIG. 9, the standardized recommended part selection unit 157 calculates the total cost of each part P displayed in the same column as the part name item column 124b selected in the part name item column 124b.

[0100] Specifically, when the first part P1 is selected as the standardized recommended part PP, the standardized recommended part selection unit 157 calculates the total cost of the first part P1 of series A, the first part P1 of series B, the first part P1 of series C, and the first part P1 of series D. The standardized recommended part selection unit 157 calculates the total cost of each part P based on the data stored in the unit price 172g of the part cost data storage unit 172, the data stored in the delivery loss cost 172h, and the data stored in the quality loss cost 172j, which were described with reference to FIG. 5.

[0101] The standardized recommended part selection unit 157 selects one part P with the minimum total cost as the standardized recommended part PP from among the parts P for which the total cost has been calculated, and presents it to the designer DU (step S115). Specifically, the standardized recommended part selection unit 157 presents the standardized recommended part PP to the designer DU by causing the standardized recommended part presentation screen 125, which was described with reference to FIG. 10, to be displayed on the display unit 12. The designer DU can reduce the number of types of part P by sequentially making design changes such as adopting the selected standardized recommended part PP as the part P of the product PR scheduled for development and improvement in the future, thereby promoting the standardization of part P. When the standardized recommended part selection unit 157 presents the standardized candidate part PK to the designer DU, the part standardization support process ends.

[0102] As described above, according to the component standardization support device 10 according to Embodiment 1, the component P with the minimum total cost including the unit price, delivery loss cost, and quality cost is selected as the recommended standardized component PP. Therefore, it is possible to select the component P recommended to be treated as a standard from an objective perspective and support the promotion of the standardization of the component P.

[0103] Also, in this embodiment, the delivery time and quality are converted into costs. Thereby, the delivery time of the component P and the quality of the component P can be evaluated on the same basis such as cost. Therefore, it becomes easier to select the recommended standardized component PP.

[0104] For many designers DU in charge of the design of each product PR, the cases are fixed for each product PR, and there is little interest in the component P selected in other product PRs. However, according to the component standardization support device 10, the non-standardized component P is selected as the recommended standardized component PP from among the components P used in the similar product PR specified by the designer DU. Therefore, the designer DU can perform the work with an overall view from a broad perspective.

[0105] Also, the selection of the component P may be biased by the designer DU due to the experience of the designer DU, the preference of the designer DU, etc. In particular, an experienced designer DU may have a fixed way of thinking due to past experience. However, according to the component standardization support device 10, since only one recommended standardized component PP is selected, the bias in the selection of the component P can be suppressed. Also, the awareness of the designer DU can be reformed. Furthermore, the designer DU can acquire knowledge such as the cost, quality, and delivery time of the component P in addition to the knowledge necessary for design such as the dimensions and shape of the component P. As a result, the designer DU can improve the breadth of knowledge about the component P. In particular, a new designer DU can acquire the component P selection work at an early stage.

[0106] In addition, data indicating unit price, delivery date, and quality are often separately managed by departments such as the material management department and the production management department. From an economic perspective, it is not easy to select the standardized recommended part PP. However, according to this embodiment, data indicating unit price, delivery date, and quality necessary for selecting the standardized recommended part PP are acquired from among the data separately managed by the design department, the material management department, and the production management department, and the standardized recommended part PP is selected. Therefore, the part P recommended to be treated as a standard can be selected as the standardized recommended part PP in an overall view.

[0107] In addition, in this embodiment, unit price, delivery date, and quality become important management indicators for selecting the standardized recommended part PP. There are cases where these management indicators are not updated. However, according to the component standardization support device 10, it becomes easier for departments such as the material management department and the production management department to recognize the importance of management indicators such as unit price, delivery date, and quality, and it is possible to promote an awareness reform such as periodically updating the management indicators.

[0108] Due to the component standardization support device 10, in the material management department, since it is necessary to periodically update the data indicating the unit price of part P and the quality of part P, communication with the supplier of part P is activated, and closer cooperation can be achieved. As a result, the improvement activities with the supplier of part P can be accelerated. Thereby, effects such as shortening the delivery date can be expected, and the cost of lost sales opportunities can be suppressed.

[0109] In addition, by presenting the sheet on which the data input on the unit price and quality data input screen 121 is output to the supplier and seeking the supplier's agreement, the supplier can easily grasp the parts with priority for improvement. Also, although there are cases where data indicating delivery date and quality are not shared with the supplier and it is difficult to set goals during improvement activities, by presenting the sheet on which the data input on the unit price and quality data input screen 121 is output to the supplier, it is possible to promote the support for improvement activities between the material management department and the supplier.

[0110] With the component standardization support device 10, in the production management department, since it is necessary to regularly update the data indicating the delivery date, it becomes possible to consider improvement measures such as small-lot procurement and to detect problems at an early stage.

[0111] Also, communication between the material management department, the production management department, and the design department can be activated, and the effect of activating improvement activities that promote cooperation between departments can also be expected. As a result, the improvement activities of the entire factory can be accelerated.

[0112] Furthermore, by installing the component standardization support device 10 in overseas affiliated companies, the method used in the domestic mother factory can also be implemented in overseas affiliated companies. As a result, the standardization of component P can be promoted globally. In overseas production, there are issues regarding logistics costs, but if the standardization of component P progresses globally, logistics costs can be suppressed, and the effect of reducing global total costs can be obtained.

[0113] In this embodiment, the standardized recommended component selection unit 157 calculates the total cost by weighting the unit price, quality loss cost, and delivery date loss cost of component P at a ratio of 1:1:1. However, the standardized recommended component selection unit 157 may change the weighting of the unit price, quality loss cost, and delivery date loss cost of component P to, for example, 1:1:2, etc., and calculate the total cost. The change in weighting is performed, for example, by the person in charge of promotion.

[0114] In this embodiment, the product-specific component data acquisition unit 151 acquires the product-specific component data G1 each time the component list data D1 is updated. However, the timing at which the product-specific component data acquisition unit 151 acquires the product-specific component data G1 is not particularly limited, and for example, the product-specific component data G1 may be acquired from the component list data D1 according to a schedule preset by the system design person in charge.

[0115] Also, the product-specific component data G1 may be stored in the product-specific component data storage unit 171 when the design person in charge DU operates the operation unit 11.

[0116] In this embodiment, the unit price data G2 and the quality data G3 are input into the component standardization support apparatus 10 by the material management person in charge MU. However, the unit price and quality data acquisition unit 152 may acquire them regularly or irregularly from the material management department server MS managed by the material management department via the communication unit 13. Similarly, the delivery date data acquisition unit 153 may acquire the delivery date data G4 regularly or irregularly from the production management department server PS managed by the production management department.

[0117] In this embodiment, the case where the product-specific component data G1 is data managed by the design department, the unit price data G2 and the quality data G3 are data managed by the material management department, and the delivery date data G4 is data managed by the production management department has been described. However, the departments that manage each data are not particularly limited. For example, the unit price data G2 may be managed by the production management department. Also, the number of departments that manage each data is not limited to three, and may be one, two, or four.

[0118] In this embodiment, by the user specifying at least one condition from among the product model number, the number of years of sales, and the specifications, data indicating similar products PR that the user recognizes as similar is extracted from the product-specific component data storage unit 171. However, the method for designating similar products PR is not particularly limited. For example, data for linking product PRs in a similar relationship may be further included in the product-specific component data storage unit 171. The standardization candidate component presentation unit 156 may extract data indicating similar product PRs from the product-specific component data storage unit 171 based on the data for linking. Note that the data for linking product PRs in a similar relationship is stored in advance in the product-specific component data storage unit 171 by the designer DU inputting the data for linking.

[0119] The product number, drawing number, part name, etc. according to this embodiment only need to be commonly recognized among departments, and may be abbreviated names instead of formal names. Also, the rule for determining the model number is not particularly limited as long as it can be commonly recognized among departments.

[0120] Data such as the product-specific parts data storage unit 171, the parts cost data storage unit 172, the unit price-quality data input screen 121, the delivery date data input screen 122, and the parts display screen 124 for similar products may be output in a file format that can be viewed and edited by each department, for example, a spreadsheet file.

[0121] [Embodiment 2] Referring to FIG. 12, the parts standardization support device 10 according to Embodiment 2 will be described. The basic configuration and basic operation of the parts standardization support device 10 according to Embodiment 2 are the same as those of the parts standardization support device 10 in Embodiment 1. However, it is different from Embodiment 1 in that the standardized recommended parts selection unit 157 is configured by artificial intelligence (AI). Hereinafter, the description will focus on the differences from Embodiment 1.

[0122] As shown in FIG. 12, the data storage unit 170 further includes a learned model storage unit 173.

[0123] The learned model storage unit 173 stores data of the learned model. The learned model is generated by using a known machine learning library and, for example, by a "supervised learning method" in which a set of data with correct labels is learned from the learning data. Note that the learned model may be learned and generated by other learning methods such as an "unsupervised learning method", a "reinforcement learning method", and a "semi-supervised learning method".

[0124] As the learning algorithm, a learning algorithm typified by a neural network can be used. The neural network has an input layer composed of a plurality of nodes to which different input parameters are input, an intermediate layer to which signals output from each node of the input layer are input, and an output layer to which signals output from the intermediate layer are input and which outputs output parameters. Note that the intermediate layer of the neural network may be composed of one or two or more.

[0125] As learning data, data for identifying component P and data indicating the cost of component P are used. As the correct label, data indicating standardized recommended component PP preliminarily selected by the person in charge of promotion is used.

[0126] In the present embodiment, the data for identifying component P is the drawing number of the design drawing of component P. The data indicating the cost of component P includes data indicating the unit price of component P, the quality loss cost of component P, and the delivery date loss cost of component P.

[0127] The standardized recommended component selection unit 157 generates a learned model and presents the standardized recommended component PP to the user using the generated learned model.

[0128] As shown in FIG. 12, the standardized recommended component selection unit 157 includes a learning unit 155a that generates a learned model and an inference unit 155b that infers the standardized recommended component PP using the learned model.

[0129] Hereinafter, the learning process by the learning unit 155a will be described. The learning process shown in FIG. 13 starts when the operation unit 11 receives an operation instructing execution by a user including the person in charge of promotion.

[0130] The learning unit 155a acquires, as teacher data, data for identifying component P and data indicating the cost of component P (step S201). The data indicating the cost of component P includes the unit price of component P, the delivery date loss cost of component P, and the quality loss cost of component P. The teacher data is input to the learning unit 155a via the communication unit 13. The correct label is added to the teacher data. Note that the correct label may not be input to the learning unit 155a at the same timing as the teacher data, and may be input to the learning unit 155a at a timing different from that of the teacher data.

[0131] The learning unit 155a repeatedly learns using teacher data (step S203), and analyzes the characteristics, rules, etc. of the data included in the teacher data. In the process of repeated learning, the learning unit 155a outputs output data that approximates the selection result by the person in charge of promotion by changing the weighting of each node. The learning unit 155a stores the learned model in the learned model storage unit 173 (step S205) and ends the learning process.

[0132] The inference unit 155b shown in FIG. 12 executes the inference process shown in FIG. 14 using the learned model stored in the learned model storage unit 173. The inference process is executed, for example, in response to an operation on the operation unit 11 of the designer DU.

[0133] The inference unit 155b inputs, as input parameters, data for identifying the standardized candidate part PK described with reference to FIG. 8 and data indicating the cost of the part P to the learned model (step S301). Specifically, the inference unit 155b inputs, as data for identifying the standardized candidate part PK, data indicating the drawing numbers for identifying each of the plurality of parts P displayed in the part name item column 124b shown in FIG. 9 to the learned model. Further, the inference unit 155b obtains, as data indicating the cost of the part P, the unit price of each of the parts P displayed in the part name item column 124b, the delivery loss cost of the part P, and the quality loss cost of the part P from the part cost data storage unit 172 shown in FIG. 5 and inputs it to the learned model.

[0134] The inference unit 155b uses the learned model to execute an inference based on the input parameters (step S303), outputs, as output parameters, data indicating the part P recommended to be treated as a standard from among the input standardized candidate parts PK (step S305), and ends the inference process.

[0135] The standardized recommended component selection unit 157 acquires data indicating a component P recommended to be treated as a standard from the output parameters output by the inference unit 155b. When the standardized recommended component selection unit 157 acquires data indicating a component P recommended to be treated as a standard, the component P indicated by the acquired data is presented to the user as a standardized recommended component PP. The standardized recommended component selection unit 157 presents the standardized recommended component PP to the user, for example, by causing the display unit 12 to display the standardized recommended component presentation screen 125 described with reference to FIG. 10.

[0136] As described above, according to the component standardization support apparatus 10 of the second embodiment, the standardized recommended component selection unit 157 selects the standardized recommended component PP using the technology of AI. Therefore, the selection of components that has been determined based on the experience value or assumption of each design engineer DU so far is revised, and the standardized recommended component PP can be determined from an objective and quantitative perspective. As a result, it is also possible to obtain improvement effects such as shortening the delivery time by reducing the number of purchasing sources and eliminating the component reallocation work when changing the production series.

[0137] In addition, even a young design engineer with little experience value can select the standardized recommended component PP, which can contribute to accelerating the design improvement activities.

[0138] In the second embodiment, the case where the learning unit 155a uses a neural network as a learning algorithm has been described as an example. However, the learning unit 155a may use other known methods, for example, genetic programming, functional logic programming, support vector machine, etc. as a learning algorithm.

[0139] In addition, although the learning unit 155a and the inference unit 155b are provided in the component standardization support apparatus 10, the learning unit 155a and the inference unit 155b may be provided in a device different from the component standardization support apparatus 10. In this case, the standardized recommended component selection unit 157 presents the standardized recommended component PP based on the output parameters output from the inference unit 155b provided in a device different from the component standardization support apparatus 10.

[0140] Note that the present disclosure is not limited to the examples of the above-described embodiments, and can be implemented in other modes by making appropriate changes.

[0141] For example, although the data storage unit 170 is stored in the auxiliary storage device 17 of the component standardization support device 10, the data storage unit 170 may be stored in a storage area of a device different from the component standardization support device 10, for example, a shared server within the company, a cloud server, or the like.

[0142] In the present disclosure, although the component P is described as an example of the object to be standardized, the object to be standardized is not limited to the component P, and may be the material, raw material, etc. of the product PR. In the case of materials and raw materials, the data of the drawing number of the component P shown in FIG. 4 is replaced with, for example, information specifying the materials and raw materials in the component list.

[0143] In the present disclosure, although the standardized recommended component PP is selected from among those other than the preset standard components and presented to the user, the standardized recommended component PP may be selected from among the components P including the standard components. In this case, the data stored in the product-specific component data storage unit 171 illustrated in FIG. 4 includes the standard components.

[0144] Although only one standardized recommended component PP is selected, a plurality of standardized recommended components PP may be selected. In this case, the component standardization support device 10 may rank and select a plurality of standardized recommended components PP. The ranks assigned to the plurality of standardized recommended components PP may be, for example, in ascending order of the total cost.

[0145] Although the standardized recommended component PP is selected based on the unit price, quality loss cost, and delivery loss cost, the component standardization support device 10 may select the standardized recommended component PP in consideration of other parameters. The component standardization support device 10 may, for example, convert environmental factors such as environmental load and power consumption during the manufacturing process, economic factors other than the unit price, the life of the component itself, the relationship with the component supplier, etc. into costs, and select the standardized recommended component PP as a parameter to be evaluated.

[0146] The quality loss cost is obtained by multiplying the return cost, which is the total value of the cost required to return component P to the supplier, the cost required for return communication, and the cost required for improvement guidance, by the nonconformance rate of the inspection conducted when component P is received. However, the method for calculating the quality loss cost is not particularly limited as long as it is cost-converted based on the quality of component P. For example, the quality loss cost may be determined based on the nonconformance rate of the inspection and other qualities. Other qualities include, for example, the reliability of the supplier, such as the failure rate of component P obtained through a follow-up survey, and the power consumption of component P, etc.

[0147] The delivery loss cost is obtained by multiplying the number of days required from the order of component P until its delivery by the labor cost of the inventory management operator. However, the delivery loss cost may also be obtained by multiplying the unit price of component P by the quantity of component P in stock held for the delivery period. In this case, the operator of inventory management inputs data indicating the quantity of stock held for the delivery period into the component standardization support device 10 via the operation unit 11. Alternatively, the component standardization support device 10 may obtain data indicating the stock quantity from the data managed by the production management department.

[0148] Also, the delivery loss cost may be calculated based on the cost incurred for stocking component P in anticipation of the delivery date. For example, it may be determined based on the value obtained by multiplying the number of days required from the order of component P until its delivery by the labor cost of the inventory management operator in the production management department and the value obtained by multiplying the unit price data of component P by the quantity of component P in stock held for the delivery period. Furthermore, the delivery cost may be determined based on, for example, the delivery date and the reliability of the delivery date. The reliability of the delivery date includes, for example, the reliability of the supplier that affects the supply stability of component P, such as the debt ratio and country risk.

[0149] The product PR may be a product composed of a plurality of components P and is not limited to air conditioners, refrigerators, etc.

[0150] The users include the design engineer DU, the material management staff MU, and the production management staff PU.

[0151] As a recording medium for recording the component standardization support program PG, a computer-readable recording medium including a magnetic disk, an optical disk, a magneto-optical disk, a flash memory, a semiconductor memory, and a magnetic tape can be used.

[0152] Note that the component data acquisition process for each product corresponds to the attribute data acquisition step, the quality data acquisition process corresponds to the quality data acquisition step, the delivery date data acquisition process corresponds to the delivery date data acquisition step, the quality loss cost acquisition process corresponds to the quality loss cost acquisition step, the delivery date loss cost acquisition process corresponds to the delivery date loss cost acquisition step, and the standardized recommended component selection process corresponds to the standardized recommended item selection step.
