In Figure 10, the design technology information managed for each entity ID includes a design technology table that has the part numbers and product names of the product, etc., and an item tank table that has the part numbers and product names of the components of the product, etc. There is.

The design technology information registration program (1) registers, for example, design technology information such as drives, motors, shafts, etc. in the design technology information storage device (2). At this time, the design technology information is managed by the entity ID. This entity id is the first
As shown in Figure 0, this is an ID number assigned to each piece of design technology information registered in the design technology information storage device (2). The entity 1d is a unique number in the entire system, and by using this number, information can be uniquely determined in the entire system. For example, a serial number starting from 1 is used as the entity ID.

For example, FIG. 10 shows how the design technology information regarding the drive is registered with the entity ID "1".

A keyword registration program (3) creates a keyword table from keywords input using a keyboard or the like and registers it in a keyword table storage device (4). As shown in FIG. 11, keywords are assigned to each entity ID. For example, the product names are expressed as keywords for the entity ID "1": "r drive 1", "r motor" and "shaft 1".

[Problems to be Solved by the Invention] Conventional search devices as described above have various problems in creating search key information such as a keyword table. First, if the keyword table is configured so that keywords can be assigned for the maximum number of components of a product, etc., which is the design target, not all design targets will have the maximum number of components, so there will be excess keywords. The problem was that resources were wasted.

Second, if the number of keywords that can be assigned to a design object is limited to a predetermined number m in order to avoid wasting the above-mentioned resources, there is a problem that it is not possible to support a design object that has more than the predetermined number m of components. Ta.

Thirdly, there is a problem in that it requires a considerable amount of time and effort for the operator to enter all the keywords one by one.

Next, the processing of the family tree table creation program (9) of the above-described embodiment will be explained with reference to FIGS. 2, 3, and 4.

Fig. 2 is a flowchart 1 diagram showing a family tree table creation program (9) according to an embodiment of the present invention, Fig. 3 is a reference drawing based on the concept of a family tree, and Fig. 4 shows a family tree table. It is a table diagram.

First, I would like to explain about Family Tree.

Design technology information is generally managed using a family tree. This family tree is a tree-like diagram based on hierarchical inclusion relationships such as the various specifications, drawings, and other design technology information necessary to manufacture a product, such as products, intermediate parts, and parts. The related information is 1-digit manufacturing control information. However, the family tree table expresses the hierarchical relationship between the design target product name and all its component product names as a connection relationship between nodes in the tree, based on design technology information, and Connection information with other nodes and corresponding identification numbers are described in the target product name and all component product names. Note that the family trees are correlated with each other by part numbers in the item tank table in the design technology information.

For example, as shown in FIG. 3, for an r drive 1 that corresponds to a product, an r motor j that corresponds to an intermediate part and a T shaft J that corresponds to a part are connected as lower nodes,
In addition, "Motor" includes "Synchro J" which corresponds to parts.
and r bearing j are connected as lower nodes.

Each node has its part number written.

In step (20), the family tree table creation program (9) reads the design technology information shown in FIG. 10 from the design technology information storage device (2).

In step (21), the entity ID and the part number and product name are extracted from the design technology table and written into the family tree table.

In steps (22) to (25), upper node part numbers are created in the family tree table. That is, a search is made to see if the part number in the design technology table mentioned above exists in the item tank table of other design technology information, and if it is, the part number in the design technology table of the design technology information is extracted and the upper node component is Write to the Family Tree table as a number. If there is no upper node, write data indicating that there is no upper node.

In steps (26) to (28), lower node part numbers are created in the family tree table. That is, a search is made to see if there is a part number in the item tank table, and if there is, the part number is extracted and written into the family tree table as a lower node part number.

If there is no lower note, data indicating that there is no lower note is written.

In step (2), once all the family tree tables are created, they are registered in the family tree table storage device (10).

For example, as shown in FIG. 4, in the family tree table, there is no upper node part number for part number '19', and there are lower node part numbers '90' and 144'. In the number "90",
The upper node part number is "19", and the lower node part numbers are 185'' and 113''.

Next, the processing of the component index creation program (11) of the above-described embodiment will be explained with reference to FIGS. 5 and 6.

FIG. 5 is a flowchart showing a component index creation program (11) according to an embodiment of the present invention, and FIGS. 6(a) and 6(b) are reference diagrams showing the process of creating a component index.

Note that the component index is composed of four tables: a design target product name table, an intermediate table A, an intermediate table B, and a component product name table.

In step (30), the component index creation program 11) stores the family tree table shown in FIG. 4 in the family tree table storage device (10).
Read from.

In step (31), the family tree table is sorted by product name. FIG. 6(a) shows a family tree table sorted by product name. By sorting, rows representing the same product name, such as r drive j, are successively grouped together.

In step (32), a component product name table is created from the family tree table.

A component part that constitutes a certain product, etc. corresponds to all nodes lower than that product, etc. in the family tree. Therefore, in the family tree table,
For a certain product name, its lower node part numbers are searched in order to extract the corresponding product name, and a table is created as component product names. Note that the above process is performed in step (3)
The processing is performed sequentially from the first row of the family tree table sorted in 1) to the lower rows.

For example, the product name for the part number "19" is "The lower node part numbers of drive 1 are "90" and "144", so the product names corresponding to the part numbers "90" and "144" are r.
``motor'' and r-shaft j, and these are written in the component product name table.

Also, the lower node part numbers of the part number "'90" are ° "185" and "113", so the part number "
The product names corresponding to "185" and "113" are "synchronized gear" and "bearing", and these are written in the component product name table.

Additionally, part numbers “144”, “185” and “
The data indicates that the lower node part number of 113'' has no lower node, so the part number is ``144'' 185
” and “113” are the lowest nodes, and the creation of the component product name table for the product name r drive 1 of the part number “l9” is completed.The right end of FIG. 6(b) shows the above result. shows.

In step (33), intermediate table B is created. That is, the entity ID extracted from the family tree table, the number of components and a pointer indicating the top address of the component product name table are written into intermediate table B.

For example, in the case of the part number "'19" with the product name "r drive", the entity ID ""1, the number of components "4", and the start address of the component product name table are "33", so the pointer is "''33" is written to intermediate table B.

In step (34), intermediate table A is created. That is, the number of items having the same name as the product name in the family tree table and a pointer indicating the start address of the intermediate table B are written into the intermediate table A.

In step (35), a design target product name table is created. The product name in the family tree table is written to the design target product name table as the design target product name at the same address as the corresponding address in the intermediate table A, as shown in FIG. 6(b).
The process of steps (32) to (35) described above is shown.

In step (36), a component index consisting of the design target product name table, intermediate table A, intermediate table B, and component product name table is registered in the component index storage device F (4A).

Next, the processing of the component condition input program (5A) and component search program (6A) of the above-described embodiment will be explained with reference to FIGS. 7 and 8.

FIG. 7 is a flowchart showing a component search program (6A) according to an embodiment of the present invention, and FIG. 8 is a reference diagram showing the processing steps of the component search program (6A).

The component condition input program (5A) inputs the design target product name and its component product name from a keyboard or the like as a search key. For example, if you want to search for design technology information related to a drive whose components are a motor and a shaft, enter r drive as the product name to be designed, and r motor 1 and shaft 1 as the component product names. Component search Program (6A) includes step (4)
0), the component index is read from the component index storage device (4A).

In step (41), a search is made to see if the design target product name exists in the design target product name table. For example, in FIG. 8, when the design target product name r drive 1 is at address "5" in the design target product name table. shows.

In steps (42) to (43), if the design target product name is found in the design target product name table, the address of the corresponding component product name table is found. That is, a pointer and the number of items are taken out from the intermediate table A at the same address as the address of the product name to be designed in which the name of the product to be designed exists, and further, the entity ID, the number of items, and the pointer are taken out from the intermediate table B using this pointer. The pointer taken out from this intermediate table B indicates the start address of the component product name in the component product name table.

For example, address "11" of intermediate table B is extracted from address "5" of intermediate table A, and address "33" of the design target product name table is extracted from address "11" of intermediate table B.

In step (44), a search is made to see if the component product name exists in the component product name table. For example, regarding "Drive 1" corresponding to the entity ID "1", the component product names "Motor 1" and "Shaft j" exist in the fourth item from address '33' in the component product name table.

In steps (45) to (46), if there is the component product name, the entity ID retrieved from intermediate table B
is passed to the design technology information extraction program (7). for example,
Entity id “1” is passed.

Note that if the design target product name or component product name cannot be found, a message to that effect will be displayed.

Then, the design technology information extraction program (7) executes the entity i
For example, the entity i shown in FIG.
The design technology information of d “1” is extracted.

The display (8) then displays the extracted design technology information. For example, design technical information J regarding a drive whose components are an r motor and a shaft is displayed.

As described above, an embodiment of the present invention automatically creates a family tree table from design technology information, and further creates a design target product name table, intermediate table A, intermediate table B, and component product name table from this family tree table. Since a component index is automatically created, it is possible to search using the name of the product to be designed and its component product name as search conditions, making it possible to realize a component index that is an efficient search key. This has the effect that component indexes can be automatically created.

Incidentally, in the above description, the case where the information is used for design technology information has been described, but it goes without saying that it can be used for other information as well.
