Description

  The present invention relates to a part configuration comparison device, a part configuration comparison method, a part configuration comparison program, and a recording medium that compare parts constituting each product among a plurality of products, and more specifically, compares parts constituting each product. The present invention relates to a component configuration comparison apparatus, a component configuration comparison method, a component configuration comparison program, and a recording medium that can be used to study cost reduction of products.

  When developing a product as a new model or an improved model from the viewpoint of providing a good product to users at a low price at the development site in the manufacturing industry, it does not impair the function of the product based on the planned specifications of the product. We are considering cost reduction to reduce costs. In particular, the cost reduction of parts costs can be achieved by replacing parts with different, inexpensive parts with the same function when the parts that make up the product have different functions between different types of products. Or by integrating a plurality of parts into one part. In addition to product design, engineers are studying such cost reductions every day.

  When comparing parts constituting each product among a plurality of products, an engineer can visually compare between two products or between products having a small number of parts. However, in recent years, products with many variations that meet user needs have been demanded, and many varieties are often produced in small quantities, so it is possible to simultaneously compare parts contained in more than 10 types of products that have been partially improved. There is a need to. In recent digital home appliances, there are products composed of 1000 or more parts, and it is difficult for an engineer to compare each part visually.

  Patent Document 1 discloses a part configuration comparison system that compares a current part configuration of a product with a part configuration at a certain point in the past for each part when designing work, particularly product specifications. When there is a design change of a product between a certain past time and the present time, the component configuration comparison system displays the part number of the changed part with an underline.

  Patent Document 2 discloses a part selection support system that supports selection of substitutes for parts constituting a product. The parts selection support system can display the parts constituting the product in a tree shape for each hierarchy, and can also display the same kind of parts belonging to the same category for the part of interest.

  In the component configuration comparison system of Patent Document 1 and the component selection support system of Patent Document 2, it is possible to consider cost reduction when developing a product by associating information on the cost of the component.

  However, the part configuration comparison system of Patent Document 1 can compare only the parts that can be identified as the same parts or the same parts before the design change for the products before and after the design change. Therefore, the component configuration comparison system of Patent Document 1 cannot compare components having the same function among different types of products. In the component configuration comparison system of Patent Document 1, it is impossible to consider cost reduction due to commonality and consolidation of components among a plurality of different types of products.

  Although the component selection support system of Patent Document 2 can display information about each component included in a product, it cannot compare a plurality of products for each component. In addition, since the component selection support system of Patent Document 2 uniformly determines whether or not a component belongs to the same classification based on the component attribute information stored in the database, the component function information is different but the same function is used. Cannot search for parts with

  For example, in the first line, information on the “March 2009 version” of the product name “A” is acquired from the configuration information 21, and information including the unit price of the “March 2009 Japanese Yen base” part is obtained from the part information 22. Show that you get.

  When the comparison target information 23 is input by the comparison target information input unit 13, the component part information acquisition unit 14 uses the configuration information 21 and the component information 22 to determine the part code information for each product unit and single component to be compared. Then, the component information 24 including the component type information and the component name information is acquired, and the acquired component information 24 is stored in, for example, a memory. The component information 24 includes information indicating a product name, a component code, a parent component code, a number, a component name, a component type, a component unit price, etc., for a unit and a single component constituting each product to be compared.

  The component information acquisition unit 14 acquires configuration information 21 related to each product from the configuration information management unit 11 for a plurality of products indicated by the comparison target information 23, and the component information management unit 12 based on the acquired configuration information 21. To acquire the component information 22 of the components constituting each product.

  The component parts information acquisition unit 14 creates a unit unit price representing a unit unit price for a unit that does not have unit price information, based on the number of individual parts constituting the unit and the unit unit price. Specifically, the component information acquiring unit 14 calculates a value obtained by multiplying the component unit price of each component constituting the unit by the number of components, and adds the calculated value to calculate the component unit price of the unit. To do.

The item “number” 24e is “3”, the item “component name” 24f is “electrolytic capacitor”, the item “component type” 24g is “capacitor”, and the item “component unit price” 24h is “10”. The component information 24 is stored in, for example, a memory in a state where the items are associated with each other as described above.

  The standard part name management means 15 is a database that stores a standard part name, which is a name based on the function of a single part and a unit, in association with the part name. The standard component name is a name based on the function of the component indicated by the functional component information, and is functional name information. The standard part name management unit 15 includes an input / output unit (not shown), and the user can use and manage the standard part name management unit 15 by the input / output unit.

  The part name is a name given according to the use of a single part or unit, whereas the standard part name is a name that is a functional generalization of the single part or unit. For example, single parts whose part names are “video IC”, “image IC”, and “video IC” have the same “image IC” defined as the standard part name, although part of the part names are different from each other. Although the unit names “stand” and “foot” are different from each other, the same “stand” is defined as the standard part name.

  FIG. 6 is a diagram showing an example of the standard part name correspondence information 25 stored by the standard part name management unit 15. In the first line of the standard part name correspondence information 25, “image IC” is displayed in the item “part name” 25a, “image IC” is displayed in the item “standard part name” 25b, and the item “component IC” is displayed in the second line. “Video IC” is displayed in the “Part Name” 25a, “Image IC” is displayed in the “Standard Component Name” 25b, and “Video IC” is displayed in the “Part Name” 25a in the third row. 25b shows "Image IC". The standard part name correspondence information 25 is stored in, for example, a memory in a state where the items are associated with each other as described above.

  The same functional part determination unit 16 configures each product to be compared based on the component part information 24 acquired by the component part information acquisition unit 14 and the standard part name stored by the standard part name management unit 15. It is determined whether the unit part and the single part have the same function. "Same function" means not only when each part has the completely same function, but also when a part that constitutes a product is replaced with another part, the product can perform the same function as before. Including cases.

  The identical function component determination unit 16 acquires the component name, component type, and component code of the comparison target single component and unit from the component component information 24, and acquires the comparison target single component and unit standard component name from the standard component information. To do. The same function part determination means 16 determines whether the part name, the part type, the part code, and the standard part name are the same for each unit and single part constituting each product to be compared, and the standard part name is It is determined whether or not they are similar, and it is determined whether or not they have the same function.

  Based on the determination by the identical function component determination unit 16, the comparison unit 17 uses the component part information 24 acquired by the component part information acquisition unit 14 to identify the same unit component and individual component that constitute each product to be compared. Comparison list information 27 in which unit parts having functions and single parts are associated is created.

  The comparison means 17 arranges unit parts and single parts determined to have the same function by the same functional parts determination means 16 in the same row, and places unit parts and single components determined to have different functions in different rows. Comparison list information 27 is created. The “same row” means not only the “row” that is a horizontal row but also the “column” that is a vertical row.

  Further, the comparison means 17 may highlight the unit parts and the single parts that are determined to have the same function in the comparison list information 27 by, for example, blinking display or changing the color. Thereby, parts having the same function can be easily found from the comparison list information 27.

  In another embodiment, the comparison unit 17 may extract only the unit components and single components determined to have the same function by the same functional component determination unit 16 and create the comparison list information 27. As a result, only parts having the same function can be easily compared. In addition, the comparison unit 17 may extract only the unit components and single components that are determined not to have the same function by the same function component determination unit 16 and create the comparison list information 27. Thereby, for example, only products having different functions can be compared between products having similar component configurations, such as products of the same type.

  Since the parts shown in the first line and the fourth line from the bottom are units, they are displayed in a different color from the line showing a single part, for example. “Unit price” of a unit represents a numerical value obtained by adding the unit prices of each part constituting the unit, and “Unit price × Number” of the unit represents a value obtained by multiplying the unit price of each part constituting the unit and the number of parts. Represents the added value. The unit “unit price × number” may be the unit price of the unit. The comparison list information 27 is stored in, for example, a memory in a state where the items are associated with each other as described above. Since the comparison list information 27 illustrated in FIG. 7 is an example, the configuration information 21 and information included in the configuration information 21 may be added to the comparison list information 27.

  In the comparison list information 27, for parts having the same functions, information such as the part name, part code, number of parts, unit price of unit, unit price × number of parts of the product is arranged side by side. Therefore, it is possible to compare the differences in the unit prices of the parts having the same function, confirm the cause of the difference in the unit prices, or consider replacing the parts.

  For products in which the parts constituting the product have been changed in the past due to the design change, the products before and after the design change can be compared with the comparison list information. As a result, it is possible to compare the transition of the component unit price of the components constituting the product in order from the past to the present, and to predict the future component unit price.

  In addition, since the unit having the part name of the stand of the product A is arranged side by side with the base of the product B, it can be easily confirmed that the parts have the same function. Further, the parts constituting the units arranged side by side are also arranged side by side in association with the parts having the same function. For example, for the angle 1 of the product A, the unit price of one part is 100 yen, and the number is 4, so the total unit price is 400 yen. As for the angle of the product B, the unit price of one part is 150 yen, and since the number is 2, the total unit price is 300 yen. Therefore, it is possible to easily know for what reason the difference in cost occurs between the plurality of parts to be compared.

  The output unit 18 outputs the comparison list information 27 created by the comparison unit 17. The output unit 18 includes, for example, a monitor and a printer, and displays the comparison list information 27 on the monitor or causes the printer to print the comparison list information 27 on paper. Further, the output unit 18 may be configured to output the comparison list information 27 to another device by wired or wireless communication.

  FIG. 8 is a flowchart showing the processing of the component configuration comparison method of the present invention. As the premise of the processing in this flowchart, the configuration information management unit 11 stores the configuration information 21 by the configuration information storage step, the component information management unit 12 stores the component information 22 by the component information storage step, and the function name storage step Thus, the standard part name management means 15 stores the standard part name correspondence information 25.

  The component configuration comparison method is executed by the component configuration comparison apparatus 1. When the component configuration comparison apparatus 1 compares a single component or a unit component constituting each product among a plurality of products, the process proceeds to step a1 and processing is started. In step a2, which is a comparison target information input step, the comparison target information input means 13 stores the comparison target information 23 input by, for example, a keyboard, for example, in a memory.

  In step a3, which is a component information acquisition step, the component information acquisition unit 14 acquires component information 24 based on the comparison target information 23 stored in the comparison target information input unit 13. The component information acquisition unit 14 acquires the configuration information 21 of the product to be compared from the configuration information management unit 11 for each product based on the configuration information acquisition condition included in the comparison target information 23. The component information acquisition unit 14 acquires the component information 22 of each component code from the component information management unit 12 for each component code included in the acquired configuration information 21.

  The component information acquisition unit 14 stores component information 24 in which the acquired configuration information 21 and the component information 22 are associated with each other, for example, in a memory. Thereby, in step a4 and subsequent steps, processing can be performed in a short time without acquiring information from the configuration information management unit 11 and the component information management unit 12.

  In step a4, the component part information acquisition unit 14 extracts unit only from the parts constituting the product in the component part information 24 acquired in step a3 to create unit list information 31, and the generated unit list information For example, 31 is stored in a memory. The component information acquisition unit 14 creates and stores unit list information 31 for each product to be compared. The processing performed by the component information acquiring unit 14 in step a4 will be described in detail later with reference to FIG.

  FIG. 9 is a diagram illustrating an example of the unit list information 31 created by the component information acquisition unit 14. The configuration information number 31 e is a number included in the component information 24. The compared flag 31f is information used when creating the comparison list information 27. The compared flag 31f is set to “1” and the initial value is set to “0” when it is determined by the same function component determination means 16 that the unit has the same function as a unit constituting another product. Therefore, a part once determined to be a part having the same function is prevented from being determined again as having the same function as another part.

The item “configuration information number” 31e indicates “15”, and the item “comparison flag” 31f indicates “0”. In the sixth line, the item “product name” 31a is “B”, the item “order” 31b is “3”, the item “part name” 31c is “stand”, the item “part code” 31d is “S0002”, The item “configuration information number” 31e indicates “30”, and the item “comparison flag” 31f indicates “0”.

  In the seventh line, the item “product name” 31 a is “C”, the item “order” 31 b is “1”, the item “component name” 31 c is “main board”, and the item “component code” 31 d is “P0001”. The item “configuration information number” 31e indicates “2”, and the item “compared flag” 31f indicates “0”. In the eighth row, the item “product name” 31 a is “C”, the item “order” 31 b is “2”, the item “component name” 31 c is “power supply board”, and the item “component code” 31 d is “P0015”. The item “configuration information number” 31e indicates “20”, and the item “comparison flag” 31f indicates “0”. In the ninth line, the item “product name” 31a is “C”, the item “order” 31b is “3”, the item “part name” 31c is “cover”, the item “part code” 31d is “S0003”, The item “configuration information number” 31e indicates “28”, and the item “comparison flag” 31f indicates “0”. The unit list information 31 is stored in, for example, a memory in a state where the items are associated with each other as described above.

  In step a5, the same functional component determination means 16 uses the unit list information 31 created by the component information acquisition means 14 in step a4, and there is a unit having the same function for the units constituting the comparison target product. It is determined whether or not. The comparison unit 17 creates unit association information 33 by associating units having the same function determined by the same functional component determination unit 16 and stores the created unit association information 33 in, for example, a memory.

  In step a6, the same functional component determination means 16 determines whether there is a single component having the same function among the single components constituting the unit determined to have the same function in step a5. The comparison unit 17 associates single components having the same function determined by the identical function component determination unit 16 to create child component association information, and stores the created child component association information in, for example, a memory. Steps a4 to a6 are identical functional component determination steps.

  In step a7, which is a comparison process and an output process, the comparison unit 17 selects a component determined to have the same function by the same function component determination unit 16 from the component part information 24 acquired by the component part information acquisition unit 14. The associated comparison list information 27 is created. The output means 18 outputs the comparison list information 27 created by the comparison means 17, proceeds to step a8, and ends the process.

  FIG. 10 is a flowchart showing in detail the process in step a4 of FIG. The processing of steps b1 to b9 described below is performed for each product to be compared by the component information acquisition unit 14.

  When the component part information acquisition unit 14 creates the unit list information 31 based on the component part information 24, the process proceeds to step b1 and the process is started. The variable representing the “number” of the component information 24 is “n”, and the variable representing the row number of the unit list information 31 to be created is “i”. In step b2, the component information acquiring unit 14 sets n = 1 and i = 0. In step b <b> 3, the component part information acquisition unit 14 acquires information related to the component with the number “n” in the component part information 24.

  In step b4, the component information acquisition unit 14 determines whether or not the component with the number “n” in the component information 24 is a unit. The component information acquiring unit 14 determines whether or not the unit is a unit by using the unit identification information included in the component information 24. If it is determined by the component information acquiring means 14 that the unit is a unit, the process proceeds to step b5. If it is determined that the unit is not a unit, the process proceeds to step b7.

  In another embodiment, the component code may include information on whether or not it is a unit component. In this configuration, the component information acquiring unit 14 uses the component code to determine whether or not the unit component is a unit. Judgment can be made.

  In step b5, the component information acquiring unit 14 sets i = i + 1. In step b6, the component information acquiring unit 14 extracts information about the component with the number “n” in the component information 24 determined to be a unit from the component information 24 and “i” in the unit list information 31. As a line, for example, it is stored in a memory. Further, the component information acquisition unit 14 stores the value of the compared flag as “0” in order to create a comparison list.

  In step b5, when the number of child parts constituting the unit is only one unit and the unit does not have a part unit price, it is determined that the unit is a dummy part or a process management part, and unit list information 31 You may perform the process which is not added to. Dummy parts or process management parts exist as data, but are not actually mounted on the product. They are virtual parts for process and management convenience, or parts that have been discontinued. And so on.

  In step b7, the component information acquiring unit 14 sets n = n + 1. In step b8, the component information acquiring unit 14 determines whether the value of n has exceeded the maximum number of “numbers” in the component information 24 for the product to be processed. If the component information acquisition unit 14 determines that n is less than or equal to the maximum number, the process proceeds to step b3. If it is determined that n exceeds the maximum number, the process proceeds to step b9 and the process ends.

  FIG. 11 is a flowchart showing in detail the processing in step a5 of FIG. When the comparison unit 17 and the same functional component determination unit 16 associate units, the process proceeds to step 1 to start processing. In step c2, the comparison means 17 defines that the product to be compared is represented by “Mx”. x is a natural number from 1 to X, and X is the maximum number of products to be compared.

  In step c3, the comparison means 17 represents x of the product Mx as i and sets i = 2. In step c4, the comparison means 17 acquires the unit list information 31 of the product Mi. Let N be the maximum value of the number of units in the unit list information 31 of the product Mi. In step c5, the comparison means 17 sets n = 1. n is a variable representing the nth information in the unit list information 31 of the product Mi. In step c6, the comparison unit 17 obtains n-th information, for example, unit information A, from the unit list information 31 of the product Mi.

  In step c7, the comparison means 17 represents x of the product Mx as j and sets j = 1. In step c8, the comparison unit 17 acquires the unit list information 31 of the product Mj. Let M be the maximum number of units in the unit list information 31 of the product Mj. In step c9, the comparison means 17 sets m = 1. m is a variable representing the m-th information in the unit list information 31 of the product Mj. In step c10, the comparison unit 17 acquires m-th information, for example, unit information B, from the unit list information 31 of the product Mj.

Therefore, when comparing the units and individual components that make up a product, in addition to having the same function, consider the unit price of the component, find the part that can reduce the cost, and examine the design change etc. It can be carried out.

  In addition, the component part information acquisition unit 14 creates unit price information representing the unit price of the unit based on the number information and unit price information of the single parts constituting the unit for the unit having no unit price information.

  As a result, the comparison unit 17 can create comparison list information 27 including the unit unit price of the unit based on the unit unit price of the unit created by the component information acquisition unit 14. Therefore, when comparing the unit and the single component constituting the product, it is possible to surely know information about the component unit price, and it is possible to appropriately examine design changes and the like.

  In addition, the same functional parts determination means 16 has a part name indicated by the part name information, a standard part name indicated by the standard part name information, and a type indicated by the part type information for the units and individual parts constituting each product to be compared. Whether or not they have the same function by determining whether or not the component codes indicated by the component code information are the same and determining whether or not the standard component names indicated by the standard component name information are similar Determine.

  As a result, even if the attribute information of the unit and the single component does not completely match, the same function component determination unit 16 can use the same function for each of the unit and the single component when the standard component names are similar. It can be reliably determined that it has. Therefore, it is possible to search and extract a substitute part having the same function between different products in a wider range.

  Further, the comparison unit 17 arranges units and single components determined to have the same function by the same functional component determination unit 16 in the same row, and arranges units and single components determined to have different functions in different rows. Comparison list information 27 representing the comparison list is created.

  As a result, when the comparison list information 27 is viewed, it is possible to easily compare units and single components having the same function.

  Further, the comparison unit 17 extracts the units and single components determined to have the same function by the same function component determination unit 16 and creates the comparison list information 27.

  As a result, the comparison means 17 can create comparison list information 27 that displays only units and single parts having the same function. Therefore, by comparing the component configurations of different products based on the comparison list information 27, it is possible to more easily study design changes and the like. Further, by comparing a plurality of products, it is possible to search for alternative parts over a wide range and extract parts having the same function.

  Further, a single component or unit that configures each product among a plurality of products with respect to a product configured to include at least one of a plurality of single components and a unit component composed of a plurality of single components by a component configuration comparison method. When comparing parts, the component configuration comparison method includes a configuration information management process, a part information management process, a comparison target information input process, a component information acquisition process, a standard part name management process, and a function determination with the same function. A process, a comparison process, and an output process are included. In the configuration information storage step, the configuration information 21 including the component code information representing the component code of each of the unit component and the single component is stored in association with the product component code information. In the component information management process, component information 22 including component code information for unit components and single components, component name information indicating a component name, and component type information indicating a type is stored in association with each component code. In the comparison target information input step, comparison target information 23 for specifying a plurality of products to be compared is input. In the component information acquisition step, when the comparison target information 23 is input in the comparison target information input step, from the configuration information 21 and the component information 22, component code information for each product unit and single component to be compared, The component information 24 including the component type information and the component name information is acquired. In the standard part name management process, part name information and standard part name information representing a standard part name that is a name based on the function of a unit or a single part indicated by the part name information are stored in association with each other. In the same functional part determination step, based on the component part information 24 and the standard part name information, it is determined whether or not the unit and the single part of each product to be compared have the same function. In the comparison step, based on the determination result in the same functional component determination step, from the component information 24, the unit and the single component having the same function among the units and the single components constituting each product to be compared are associated with each other. Comparison list information 27 is created. In the output process, the comparison list information 27 created in the comparison process is output.

  Accordingly, it is possible to appropriately determine whether or not the unit and the independent component constituting the comparison target product have the same function by the same functional component determination step. By the comparison process, the comparison list information 27 in which the units and independent parts constituting each product are associated by function can be created. Therefore, parts having the same function can be appropriately compared among a plurality of products by the part configuration comparison method. As a result, it is possible to easily examine the replacement of parts, the design change, and the integration of parts for the units and independent parts constituting each product. Moreover, since the component structure comparison apparatus 1 can simultaneously compare the component parts of a plurality of products, it is possible to search for and easily extract alternative parts having the same function.

  Furthermore, a component configuration comparison program that causes a computer to function as the component configuration comparison apparatus 1 can be provided.

  Furthermore, it is possible to provide a computer-readable recording medium for recording the component configuration comparison program.
