Description

The present invention relates to a parts management system for managing parts constituting the product.

  Since the parts and the number of parts constituting a product are enormous, it is difficult to manage them manually. Therefore, various parts management systems for managing parts have been proposed (see, for example, Patent Document 1 and Patent Document 2).

  Specifically, Japanese Patent Laid-Open No. 2004-228688 processes child part information when abolishing parent part information from parent part information related to a parent part composed of a plurality of child parts and child part information related to a plurality of child parts. A component information processing apparatus is disclosed. In particular, when the part information of a parent part to be abolished is registered, this part information processing apparatus searches for a child part constituting the parent part. Then, among the child parts, the child parts that also constitute the other parent parts are kept in the database, and the child parts that constitute only the parent parts to be abolished are subjected to processing for setting the sales deadline and the delivery deadline. Thus, the component information processing apparatus can easily abolish component information to be abolished and can prevent a decrease in information processing efficiency. However, this Patent Document 1 does not disclose any detailed method for searching for parts to be abolished.

Patent Document 2 discloses a product and component management method for managing the structural relationship between components classified into a plurality of pyramid-shaped stages and products formed by these components. In particular, this management method includes an identification step of identifying a relationship between a product one level higher or lower than a predetermined level among a plurality of levels and a part constituting the product, and attaching an identification code identified to the product or part. Is provided. With this identification configuration, products and parts between a plurality of stages are managed based on an identification code in an upper or lower vertical relationship. This management method of component parts can be simplified by unifying the management direction so that the entanglement between data can be eliminated, the relationship between products and components can be easily searched, Trouble can be reduced. However, the technique described in Patent Document 2 does not search for parts to be abolished.

  By the way, in the conventional parts management system, when a product to be abolished occurs, it is necessary to search for the part in order to abolish the part used in the product. At this time, in the conventional parts management system, if a part to be abolished is shared with other products that are not to be abolished, it cannot be abolished. There is.

  Here, in the conventional parts management system, such a search for obsolete parts is performed by using the configuration information indicating the parent-child relationship between products and parts, that is, which parts are used to configure the product for each product. Referring to the configuration information enumerated in the form of a tree, for example, the back-expansion traces back to the higher-level products and parts for all the parts that make up the product, and searches for shared relationships between products Is done by doing.

  Specifically, in the conventional parts management system, as shown in FIG. 7A, a list of all parts used in the product to be abolished is created based on the configuration information. As shown in b), the highest level product in which each part is used is obtained by executing reverse development that goes back to the higher level product or part for each part in the list over all hierarchical levels. Then, in the conventional parts management system, as shown in FIG. 7C, the parts to be abolished are obtained by extracting all parts whose products in the highest hierarchy are products to be abolished.

  Therefore, the conventional parts management system has a problem that the search time is very long for a product composed of a large number of parts and having configuration information having a deep tree hierarchy.

The present invention has been devised to solve the problems described above, it aims to provide a parts management system which can significantly reduce the search time for searching the components to abolish And

  The present invention is a data management unit that manages the parts that make up a product in a tree shape based on the usage relationship, and determines which parts can be removed from the parts used in the product when the product is abolished This is a parts management system including an obsolete part determination unit. In order to solve the above-mentioned problem, the obsolete-part determination unit of this part management system stores a first list that lists all parts used in the product to be abolished and the first list. For each part, a list creation unit that creates a second list that enumerates upper products or parts by back-expanding only one level, and all products or parts in the upper level reverse-expanded in the second list , Comparing with the parts included in the first list, and all the products or parts in the upper hierarchy which are back-expanded in the second list are only candidates for being included in the first list Among the abolition candidate part calculation unit obtained as a part and the abolition candidate parts obtained by the abolition candidate part calculation part, a part in which the upper hierarchy part reversely expanded in the second list is not a discontinuation candidate part Excluded from discontinued candidates, the remaining abolition candidate components, and having a said abolition possible component determining unit that determines as a discontinued possible components.

According to the parts management system according to the present invention, by keep the implosion dating back parts of the hierarchy only one level, it is not necessary to perform the reverse deployment across all hierarchical levels, the search time for obsolete possible components greatly Can be shortened.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[Operation of parts management system]
In the case where there is a product to be abolished, such a component management system is configured such that a predetermined access displayed on the display device 14 of the input / output device 10 by the user accessing the processing server 20 via the input / output device 10 of the user. Browse the screen and specify the product you want to discontinue. In response to this, the processing server 20 determines and searches for abolishable parts among the parts used in the specified product based on the configuration information stored in the component database 30. A list listing the parts is displayed on the display device 14 of the input / output device 10. As a result, the user can recognize the parts that can be abolished by abolishing the product and determine the actual abolition of parts.

  Further, in response to the user's instruction to delete the parts displayed in the list, the processing server 20 stores the products to be discontinued and the parts used in the product and displayed in the list from the component database 30. Delete information about.

  When the component is abolished in this way, the processing server 20 searches for a component to be abolished with the abolition of the product according to a series of steps as shown in FIG. 6 while creating the list shown in FIG. . Here, the case where two products 1 and 2 are abolished among the products specified by the configuration information shown in FIGS. 3 and 4 will be described.

  First, as shown in FIG. 6, when the processing server 20 inputs a list of products to be abolished designated by the user under the control of the CPU 21 in step S1, the processing server 20 refers to the component database 30 in step S2. Then, a list (hereinafter referred to as a first list) listing all the parts used in the products 1 and 2 to be abolished is created in the RAM 22 or the like.

Specifically, in the processing server 20, the parts constituting the product 1 are the two parts A1 and A2, the child parts constituting the part A1 are the parts B1, and the child parts constituting the part A2 are the two parts. B2, B3, the parts constituting the product 2 are the two parts A3, A4, the child parts constituting the part A3 are the two parts B2, B4, and the grandchild parts constituting the part B4 are the parts C1. There, constituting child component parts A4 are two parts B5, B6, since grandchild component constituting the component B6 is part C2, as shown in FIG. 5 (a),
Part A1
Part A2
Part A3
Part A4
Part B1
Part B2
Part B3
Part B4
Part B5
Part B6
Part C1
Part C2
Such a component group is stored in the first list 101 and stored in the RAM 22 or the like.

  Subsequently, in step S3 in FIG. 6, the processing server 20 refers to the component database 30 under the control of the CPU 21 and does not store all the hierarchical levels for each component stored in the first list 101. Backward expansion is performed by going back one layer, and a list (hereinafter referred to as a second list) that enumerates products and parts that are higher by one layer is created in the RAM 22 or the like.

Specifically, the processing server 20 has only one layer for each of the 12 components A1, A2, A3, A4, B1, B2, B3, B4, B5, B6, C1, C2 stored in the first list. By going back up the hierarchy, as shown in Fig. 5 (b),

Part A2-Product 1
Part A3-Product 2
Part A4-Product 2, Product 3
Part B1-Part A1
Part B2-Part A2, A3
Part B3-Part A2, A5
Part B4-Part A3
Part B5-Part A4
Part B6-Part A4
Part C1-Part B4
Part C2-Part B6
The second list 102 composed of the component group group 102a and the upper layer component (product) 102b is configured and stored in the RAM 22 or the like.

  Subsequently, in step S4 in FIG. 6, the processing server 20 creates a third list 104 in the RAM 22 or the like that stores components that can be finally abolished. At this point, the third list 104 is an empty list.

  Subsequently, in step S5 and step S6, the processing server 20 includes, in the first list 101, all the products or parts of the upper hierarchy reversely expanded in the second list 102 under the control of the CPU 21. It is determined whether there is a part that is present, and only such a part is obtained as a candidate for abolition.

Parts Specifically, the processing server 20, as shown in FIG. 5 (c), including of the twelve component group 102a stored in the second list 102, the product 3 out discontinued subject to an upper layer Ten parts A1, A2, A3, B1, B2, B4, B5, B6, C1, C2 other than A4 and the part B3 including the part A5 not included in the first list are abolished A candidate component group 103 is assumed.

  Then, in step S7 to step S9 in FIG. 6, the processing server 20 includes an upper layer component (product) 102b that is reversely expanded in the second list 102 in the abolishment candidate component group 103 under the control of the CPU 21. It is determined whether there is a part that is not an abolishable candidate part, such a part is excluded from the abolished candidates, and the remaining abolished candidate parts are stored in the third list 104 as the abolishable parts. The process ends.

Specifically, the processing server 20, as shown in FIG. 5 (d), among the ten abolition candidate parts A1, A2, A3, B1, B2, B4, B5, B6, C1, and C2, abolition candidates. The parts B5 and B6 having the part A4 which has not been made a part as upper-layer parts and the part C2 having the part B6 excluded from the abolishment candidate parts as upper-layer parts are excluded from the abolishment candidates, and the remaining seven The parts A1, A2, A3, B1, B2, B4, and C1 are stored in the third list 104 as obsolete parts and stored in the RAM 22 or the like.

  The processing server 20 is made up of obsolete parts that are surely excluded from the parts used in the non-decommissioned product among the parts used in the decommissioned product through such a series of steps. A third list 104 can be created.

[Effect of the embodiment]
As described above in detail, in the component management system according to the embodiment of the present invention, the processing server 20 lists the first component that lists all components used in the product to be abolished under the control of the CPU 21. For each part stored in the first list 101, and a second list 102 that lists products or parts that are higher by one layer. Then, under the control of the CPU 21, the processing server 20 obtains only the parts in which all the products or parts of the upper hierarchy reversely expanded in the second list are included in the first list as the abolition candidate parts. Among the obtained abolition candidate parts, a part whose upper hierarchy part (product) 102b reversely developed in the second list 102 is not an abolition candidate part is excluded from the abolition candidates, and the remaining abolition candidate parts are Decide as a disposable part.

  In this way, in this parts management system, it is not necessary to perform back-expansion across all hierarchical levels by limiting the back-expansion going back to the part hierarchy to only one level, so the extraction of obsolete parts can be performed very quickly. It can be carried out. As a result, it is possible to improve the responsiveness of presenting the third list 104 including the parts that can be abolished in response to the designation of the product to be abolished by the user, and to greatly shorten the search time.

  In particular, in this component management system, the number of searches for abolishable components is reduced in advance by comparing the two first tables 101 and the second table 102, so that the search time can be greatly reduced. it can.

  The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made depending on the design and the like as long as the technical idea according to the present invention is not deviated from this embodiment.
