Unit 13. In addition, although the personal computer 10 was shown as an operation part, it is not restricted to this. Further, the number of personal computers 10 as the operation unit is not limited to one, but may be plural.

  The server 20 includes a storage unit 21 that stores product information, a check list creation unit 22 that creates a check list, and a search unit 23 that retrieves information stored in the storage unit 21.

  The storage unit 21 includes a master database group 50 related to products and a product number database group 60 that stores a check list created for each product.

  The master database group 50 includes a product group database 51 that stores type information of each product, and a component database 52 that stores information on each component constituting the product stored in the product group database 51. In addition, it has a standard check item database 53 that stores check items for each component stored in the component database 52. Further, a product classification database 54 for classifying products stored in the product group database 51 and a general-purpose item for storing information on whether or not each check item stored in the standard check item database 53 is a general-purpose item. And a database 55. FIG. 2 is a conceptual diagram showing the database structure of the master database group 50.

  The product group database 51 stores the applicable product information of products. For example, information such as “product group a”, “product group b”, and “product group c” is stored.

  In the component database 52, each component for the information stored in the product group database 51 is stored. For example, information such as “element a”, “element b”, “element c”, and “element d” is stored for the information “product group a”.

  The standard check item database 53 stores check items for each piece of component information stored in the component database 52. For example, information such as “item a11” and “item a12” is stored for the information “element a” of “product group a”.

  The product classification database 54 stores information for classifying information stored in the product group database 51. For example, “product group a” and “product group b” store information such as “classification A”, and “product group c” stores information such as “classification B”.

  The general-purpose item database 55 stores information indicating whether or not the check items stored in the standard check-item database 53 are items that should be general-purpose. In other words, items that should be generalized are important check items that should be checked for all products. For example, information such as “1” is stored because “item e21” is an item that should be general-purpose, and “0” is stored because “item a11” is not an item that should be general-purpose.

  The check list creation unit 22 includes a creation unit 22a that creates a check list, a comparison determination unit 22b that collates information stored in the master database group 50 in order to create a check list, and a master database group 50. And an extraction unit 22c for extracting information.

  The comparison determination unit 22b determines whether there is a product group that includes a component for which the check list is to be created in another product group that is different from the product group to which the target product for which the check list is to be created belongs. In the extraction unit 22c, information stored in the master database group 50 that is necessary in the course of processing is extracted. Based on the information extracted by the extraction unit 22c, a check list is created by the creation unit 22a. Further, the creation unit 22a stores the created checklist in the product number database group 60, thereby adding new information to the product number database group 60, and the product number database group 60 is updated.

  The search unit 23 can search the information stored in the storage unit 21. For example, when the user inputs an arbitrary keyword (phrase) using the input unit, information including the input keyword is extracted. Can do.

  The LAN 30 connects the personal computer 10 and the server 20, enables data communication between the personal computer 10 and the server 20, and forms a communication network.

(First embodiment)
A series of processes performed using the checklist system 1 of the present embodiment will be described with reference to FIG. Hereinafter, the database may be referred to as DB.

  In this embodiment, the product name is “001”, the product group is “product group a”, and the check items for the constituent elements “element a”, “element b”, and “element c” are the target products for creating the check list. An example of the case of extracting the. In the present embodiment, the search unit 23, the product classification DB 54, and the general-purpose item DB 55 may not be included.

  FIG. 3 is a flowchart for explaining a series of processes performed using the checklist system 1 of the first embodiment.

  First, a box for inputting a product number name and a list of product groups stored in the product group DB 51 are displayed on the output unit 13.

  In step S <b> 101, the user of the check list system 1 inputs “001” as the product number for which the check list is to be created by the input unit 12 while displaying it on the output unit 13.

  In step S <b> 102, the user of the check list system 1 selects “product group a”, which is a product group to which the product number for which the check list is to be created belongs. Then, based on the information stored in the component DB 52, the component information “element a” “element b” “element c” “element d” corresponding to the product group “product group a” is displayed on the output unit 13. The

  In step S <b> 103, the user of the check list system 1 uses the input unit 12 to select the component “element a”, “element b”, and “element c” whose check items are to be extracted from the component information displayed on the output unit 13. .

  In step S104, the check items of the component group “product group a” selected in step S102 and the component elements “element a”, “element b”, and “element c” selected in step S103 are standard check items. Based on information in the DB 53, the extraction unit 22c extracts the information. That is, “item a” is extracted as “item a11”, “item a12”, “element b” is extracted as “item b11”, and “element c” is extracted as “item c11”.

  In step S105, the comparison / determination unit 22b determines whether the same components as those selected in step S103 are present in the product group other than the product group “product group a” selected in step S102. If the comparison determination unit 22b determines in step S105 that the same component as that selected in step S103 exists in another product group different from the product group selected in step S102, the process proceeds to step S106. Will migrate. On the other hand, if the comparison determination unit 22b determines in step S105 that the same component as that selected in step S103 does not exist in another product group different from the product group selected in step S102, step S107 is performed. The process moves on. In this embodiment, the comparison determination unit 22b determines that “element a” “element c” exists in “product group b” and “element b” “element c” exists in “product group c” in step S105, and step S106. The process moves on.

  In step S106 transferred from step S105, the product group “product group a” selected in step S102 is a product group different from “element a”, “element b”, and “element c” selected in step S103. Check items are extracted by the extraction unit 22c. In the present embodiment, in step S106, “item a21” “item c21” of “product group b” and “item b31” “item c31” of “product group c” are added and extracted by the extraction unit 22c. .

  In step S107, a check list is created by the creation unit 22a based on the information extracted in step S106. Then, the information stored in the check list DB 61 is updated as a newly created check list. In this embodiment, as the check item of the product number “001”, “element a” is “item a11” “item a12” “item a21”, “element b” is “item b11” “item b31”, and “element c” is “Item c11”, “Item c21”, and “Item c31” are extracted, and a check list is created.

  In step S105, if the comparison determination unit 22b determines that the same component does not exist in another product group, the creation unit 22a checks in step S107 based on the information extracted in step S104. A list is created.

  According to the check list system 1 of the present embodiment, a check list can be created while reflecting check items of a product group different from the product group to which the target product for which the check list is created belongs. In other words, not only check items for the product group “product group a” to which a target product for which a check list is to be created belongs, but also check items for other product groups can be extracted to create a check list.

  As described above, the check list system 1 according to the present embodiment creates a check list with reference to check items not only for the same type of product group but also for other types of product groups. can do. Therefore, for example, in product development, product design can be performed while eliminating design errors.

  In each embodiment described below, the same components as those in the first embodiment described above are denoted by the same reference numerals, detailed description thereof will be omitted, and different components will be described in detail.

(Second Embodiment)
A series of processes performed using the checklist system 1 of the present embodiment will be described with reference to FIG.

  In this embodiment, the product name is “002”, the product group is “product group a”, and the check items for the components “element a”, “element b”, and “element c” are the target products for which the checklist is created. An example of the case of extracting the. In the present embodiment, based on the information stored in the product classification DB 54, a checklist is created by reflecting only the information of the product group belonging to the product classification “class A” to which the product group “product group a” belongs. The case is illustrated. In the present embodiment, the search unit 23 and the general-purpose item DB 55 may not be included.

  In step S <b> 201, as in step S <b> 101, the user of the check list system 1 inputs “002” as a product number for which a check list is to be created by the input unit 12 while being displayed on the output unit 13.

  In step S202, as in step S102, the user of the checklist system 1 selects “product group a” that is the product group to which the product number for which the checklist is to be created belongs.

  In step S203, as in step S103, the user of the checklist system 1 selects the component “element a” “element b” “element c” for which the check item is to be extracted from the component information displayed on the output unit 13. Selection is made by the input unit 12.

  In step S204, as in step S104, check items for the component group “product group a” selected in step S202 and the component elements “element a”, “element b”, and “element c” selected in step S203. Is extracted by the extraction unit 22c based on the information in the standard check item DB 53.

  In step S205, when reflecting the check items of the other product group different from the product group selected in step S202, the user of the check list system 1 limits the range for extracting the check items based on the product classification. Select whether or not. Note that the user of the checklist system 1 can make a selection by marking a check box displayed on the output unit 13 with the input unit 12.

  In step S205, when the user of the checklist system 1 reflects only the check items of other product groups belonging to the product group classification selected in step S202, that is, when the extraction range is limited by the product classification. The process proceeds to step S206. In step S205, when the user of the checklist system 1 also reflects the check items of other product groups that do not belong to the product group classification selected in step S202, that is, the extraction range is not limited by the product classification. In that case, the process proceeds to step S208. In the present embodiment, check items are extracted because only items with the same product classification are reflected, so the corresponding check box is marked, and the process proceeds to step S206.

  In step S206 transferred from step S205, the same component as that selected in step S203 exists in another product group that belongs to the same product category as the product category “class A” to which “product group a” belongs. The comparison / determination unit 22b determines whether it is present. In step S206, the comparison determination unit determines that the same component as that selected in step S203 exists in another product group that belongs to the same product category as the product category “class A” to which the product group “product group a” belongs. If 22b determines, the process proceeds to step S207. On the other hand, in step S206, the comparison is made if the same component as that selected in step S203 does not exist in the other product group belonging to the same product category as the product category “class A” to which the product group “product group a” belongs. If the determination unit 22b determines, the process proceeds to step S210. In the present embodiment, the comparison determination unit 22b determines that the same “product group b” as the product classification “class A” to which the “product group a” belongs is present, and the process proceeds to step S207.

  In step S207 transferred from step S206, the “element a” “element” selected in step S203, which is another product group belonging to the same product classification as the product classification “class A” to which the product group “product group a” belongs. The check item b "" element c "is extracted by the extraction unit 22c. In the present embodiment, “item a21” and “item c21” of “product group b” are added and extracted by the extraction unit 22c.

  In step S210, a check list is created by the creation unit 22a based on the information extracted in step S207. Then, the information stored in the check list DB 61 is updated as a newly created check list. In this embodiment, “element a” is “item a11”, “item a12”, “item a21”, “element b” is “item b11”, and “element c” is “item c11” as the check item of the product number “002”. “Item c21” is extracted, and a check list is created.

  When the process proceeds from step S206 to step S210, a check list is created by the creation unit 22a based on the information extracted in step S204 in step S210.

  Further, when the processing is shifted from step S205 to step S208, in step 208, the same components as those selected in step S203 are present in the product group different from “product group a”, as in step S105. It is judged by the comparison judgment part 22b whether it is. If the comparison determination unit 22b determines in step S208 that the same component as that selected in step S203 is present in another product group different from the product group selected in step S202, the process proceeds to step S209. Will migrate. On the other hand, when the comparison determination unit 22b determines in step S208 that the same component as that selected in step S203 does not exist in another product group different from the product group selected in step S202, step S210 is performed. The process moves on.

  In step S209 transferred from step S208, as in step S106, the product group is different from the product group “product group a” and the “element a”, “element b”, and “element c” selected in step S203 are changed. Check items are extracted by the extraction unit 22c. In step S210, a check list is created by the creation unit 22a based on the information extracted in step S209. On the other hand, when the process proceeds from step S208 to step S210, a checklist is created by the creation unit 22a based on the information extracted in step S204 in step S210.

  According to the check list system 1 of the present embodiment, it is possible to create a check list while reflecting only the check items of other product groups belonging to the product classification of the product group to which the target product for which the check list is created belongs. Therefore, when reflecting check items of other product groups, it is possible to create check lists by reflecting only check items of other product groups having the same product classification as the target product.

  In this way, checklists can be created with reference to check items not only for the same type of product group of the same product classification but also for other types of product groups, so only the appropriate items are extracted as check items and the checklist is extracted. Can be created. Therefore, it is possible to create a check list free from check item leakage and noise.

(Third embodiment)
A series of processes performed using the checklist system 1 of the present embodiment will be described with reference to FIG.

  In this embodiment, the product name is “003”, the product group is “product group a”, and the check items for the components “element a”, “element b”, and “element c” are the target products for which the check list is created. An example of the case of extracting the. In the present embodiment, a case where a check item including an arbitrary word / phrase is extracted by using the search unit 23 only as a check item including the same component as the component for which the search target range is selected is used to create a check list. Illustrate. In the present embodiment, the product classification DB 54 and the general-purpose item DB 55 may not be provided.

  In step S301, as in step S101, the user of the checklist system 1 inputs “003” as the product number for which the checklist is to be created by the input unit 12 while displaying it on the output unit 13.

  In step S302, as in step S102, the user of the checklist system 1 selects “product group a”, which is the product group to which the product number for which the checklist is to be created belongs.

  In step S303, as in step S103, the user of the checklist system 1 selects the component “element a” “element b” “element c” for which the check item is to be extracted in the component information displayed on the output unit 13. Selection is made by the input unit 12.

  In step S304, as in step S104, the check items of “element a”, “element b”, and “element c” that are “product group a” selected in step S302 and selected in step S303 are the standard items. Based on the information in the check item DB 53, the extraction unit 22c extracts the information.

  In step S <b> 305, the user of the checklist system 1 inputs a word to be searched by the input unit 12 in a box for inputting a word to be searched displayed on the output unit 13. In the present embodiment, the search phrase “phrase α” is input by the input unit 12.

  In step S306, a search target range is determined. That is, whether to search only the check item corresponding to the same component as the one selected in step S303 or whether to search also the check item not including the same component as the one selected in step S303 is a check list. The user of system 1 selects. Note that the user of the checklist system 1 can make a selection by marking a check box displayed on the output unit 13 with the input unit 12.

In step S306, if the user of the checklist system 1 determines that the search target range is only the check items corresponding to the same components as those selected in step S303, the process proceeds to step S307. On the other hand, in step S306, if the user of the checklist system 1 also searches for a check item that does not include the same component as that selected in step S303, the process proceeds to step S309.
In this embodiment, the search target range is limited to only the check items corresponding to the same components as those selected in step S303, so that the corresponding check box is marked, and the process proceeds to step S307.

  In step S307 transferred from step S306, as in step S105, whether or not the same component as that selected in step S303 is present in a product group different from “product group a” is compared and compared 22b. Judgment. If the comparison determination unit 22b determines in step S307 that the same component as that selected in step S303 exists in another product group different from the product group selected in step S302, the process proceeds to step S308. Will migrate. On the other hand, when the comparison determination unit 22b determines in step S307 that the same component as that selected in step S303 does not exist in another product group different from the product group selected in step S302, step S312 is performed. The process moves on. In this embodiment, the comparison determination unit 22b determines that “element a” and “element c” exist in “product group b” and “element b” and “element c” exist in “product group c” in step S307, and step S308. The process moves on.

  In step S308 transferred from step S307, the check items “element a”, “element b”, and “element c”, which are different from “product group a” and selected in step S303, are first extracted by the extraction unit 22c. Extracted by Then, from the extracted check items, only the check item including the input word to be searched is extracted by the extraction unit 22c. In the present embodiment, in step S308, first, “item a21” “item c21” of “product group b” and “item b31” “item c31” of “product group c” are respectively extracted by the extraction unit 22c. Only “item a21” of “product group b” including the inputted “word α” is added and extracted by the extraction unit 22c.

  In step S312, a check list is created by the creation unit 22a based on the information extracted in step S308. Then, the information stored in the check list DB 61 is updated as a newly created check list. In this embodiment, “element a” is “item a11”, “item a12”, “item a21”, “element b” is “item b11”, and “element c” is “item c11” as check items of the product number “003”. Are extracted and a checklist is created.

  When the process proceeds from step S307 to step S312, a checklist is created by the creation unit 22a based on the information extracted in step S304 in step S312.

  Further, when the processing is shifted from step S306 to step S309, in step 309, the same component as that selected in step S303 exists in the product group different from “product group a”, as in step S105. It is judged by the comparison judgment part 22b whether it is. If the comparison determination unit 22b determines in step S309 that the same component as that selected in step S303 exists in another product group different from the product group selected in step S302, the process proceeds to step S310. Will migrate. On the other hand, if the comparison determination unit 22b determines in step S309 that the same component as that selected in step S303 does not exist in another product group different from the product group selected in step S302, step S311 The process moves on.

  In step S310 transferred from step S309, the check items “element a”, “element b”, and “element c”, which are different from “product group a” and selected in step S303, are first extracted by the extraction unit 22c. Extracted by In addition to the extracted check items, the check unit of all product groups different from the “product group a” and including the input search phrase is extracted by the extraction unit 22c. That is, a check item for a component not selected in step S303 is also searched. In step S312, a check list is created by the creation unit 22a based on the information extracted in step S310.

  On the other hand, when the processing is shifted from step S309 to step S311, in step S311, the check unit includes all the check items of the product group different from “product group a” and includes the input search word / phrase. 22c is extracted. In step S312, a checklist is created by the creation unit 22a based on the information extracted in step S311.

  According to the check list system 1 of the present embodiment, it is possible to search and extract check items including the input desired word / phrase and create a check list. For example, when the target range of the search by word / phrase is only another product group including the same component as the selected one, the noise of the check item to be extracted can be reduced. Therefore, only a more appropriate item can be extracted as a check item to create a check list. For example, if the scope of the search by word includes a product group that does not contain the same component as the selected one, even if the product group does not contain the same component as the selected one, the check item You can create a checklist by extracting words that match. Therefore, it is possible to create a check list with less check items.

(Fourth embodiment)
A series of processes performed using the checklist system 1 of the present embodiment will be described with reference to FIG.

  In this embodiment, the product number is “004”, the product group is “product group a”, and the check items for the constituent elements “element a”, “element b”, and “element c” are the target products for which the check list is created. An example of the case of extracting the. In the present embodiment, the case where the general-purpose check item is further extracted by extracting the general-purpose check item and the check list is created is illustrated. In the present embodiment, the search unit 23 and the product classification DB 54 may not be included.

  In step S 401, as in step S 101, the user of the check list system 1 inputs “004” as a product number for which a check list is to be created by the input unit 12 while being displayed on the output unit 13.

  In step S402, as in step S102, the user of the check list system 1 selects “product group a” that is a product group to which the product number for which the check list is to be created belongs.

  In step S 403, as in step S 103, the user of the check list system 1 selects the component “element a”, “element b”, and “element c” for which check items are to be extracted from the component information displayed on the output unit 13. Selection is made by the input unit 12.

  In step S404, in the same manner as in step S104, the check items of “product group a” selected in step S402 and “element a”, “element b”, and “element c” selected in step S403 are standard checks. Based on the information in the item DB 53, the extraction unit 22c extracts the information.

  In step S405, the comparison / determination unit 22b determines whether the same component as that selected in step S403 is present in a product group different from the “product group a” selected in step S402. If the comparison determination unit 22b determines in step S405 that the same component as that selected in step S103 exists in another product group different from the product group selected in step S402, the process proceeds to step S406. Will migrate. On the other hand, when the comparison determination unit 22b determines in step S405 that the same component as that selected in step S403 does not exist in another product group different from the product group selected in step S402, step S407 is performed. The process moves on. In this embodiment, the comparison determination unit 22b determines that “element a” “element c” exists in “product group b” and “element b” “element c” exists in “product group c” in step S405, and step S406. The process moves on.

  In step S406 transferred from step S405, check items for “element a”, “element b”, and “element c” that are different from the “product group a” selected in step S402 and selected in step S403 Is extracted by the extraction unit 22c. In the present embodiment, in step S406, “item a21” “item c21” of “product group b” and “item b31” “item c31” of “product group c” are added and extracted by the extraction unit 22c. .

  In step S407, based on the information in the general-purpose item DB 55, check items that should be general-purpose among the check items stored in the standard check-item DB 53 are extracted by the extraction unit 22c. In this embodiment, in step S407, “item e21” of “product group b” and “item g41” of “product group d” are added and extracted by the extraction unit 22c.

  In step S408, a check list is created by the creation unit 22a based on the information extracted in step S407. Then, the information stored in the check list DB 61 is updated as a newly created check list. In this embodiment, as the check item of the product number “004”, “element a” is “item a11” “item a12” “item a21”, “element b” is “item b11” “item b31”, and “element c” is “Item c11” “Item c21” “Item c31” and “Item e21” “Item g41” are extracted as general check items, and a check list is created.

  According to the checklist system 1 of the present embodiment, important check items to be checked in product development are extracted while reflecting check items of a product group different from the product group to which the target product for which the check list is created belongs. A checklist can be created. In this way, checklists that are important check items that should be generalized can be extracted and a checklist can be created, so that it is possible to create a checklist with no check item omissions.

  The embodiments of the present invention have been described above with specific examples. However, the present invention is not limited to the above-described configuration, and various modifications can be made without changing the gist of the invention. For example, the configurations of the above-described embodiments can be combined with each other.
