BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a system for producing a manufacturing parts table according to the present invention.

FIG. 1 is a diagram for explaining a configuration of a production parts table diagram creation system according to an embodiment of the present invention.

As shown in FIG. 1, a system 1 for creating a manufacturing parts table according to the present embodiment has an item file 20 (item code 201, item name 20) of a design parts table shown in FIG.
2, the work process name 203) and the configuration file 21 (parent item code 211, sibling sequence 212,
Based on the data of the child item codes 213), an X address for screen display is created for each item code 201, and a multi-layer component expansion unit 10 that expands components in multiple layers, and a multi-layer component expansion unit 10 Y to X address of each part developed in
A hierarchical address table creating unit 11 that creates a hierarchical address table 22 (index 220, item code 221, X address 222, Y address 223) shown in FIG. A hierarchy table creation unit 12 that creates a hierarchy table and a hierarchy diagram by using data; a hierarchy diagram editing unit 13 that edits the created hierarchy table and the hierarchy diagram to create a manufacturing parts table diagram; The display unit 14 includes a display unit 14 for displaying a hierarchical diagram and a manufacturing parts table diagram, and a Gantt chart generation unit 15 for generating a Gantt chart for a manufacturing plan from the manufacturing parts table diagram.

Next, a procedure for creating a manufacturing parts table diagram in the manufacturing parts table creating system 1 of the present embodiment will be described.

As shown in FIG. 3, the procedure for creating the manufacturing parts table diagram is as follows: a step 301 for creating a hierarchical diagram from the designed parts table by the hierarchical table diagram creating section 12; And a step 302 for assigning or editing a work process to create a manufacturing parts table diagram.

Hereinafter, Step 301 and Step 30 will be described.
2 will be described in detail.

As shown in FIG. 4, the hierarchical diagram creation process in step 301 first has a sequence indicating the parent-child relationship between the item file and the component and the display order of sibling components from the hierarchical component list of the design. A configuration file is input (step 401), and an index 220 and an X address 222 for each item are created from the data of the item and the configuration file by the multi-layer part expanding unit 10 (step 40).
2) Next, the hierarchical address table creating unit 11 creates a Y address for the X address 222 of each item, and creates a hierarchical address table 22 (step 40).
3) The hierarchical diagram creation unit 12 creates a hierarchical diagram (step 404).

In the process of creating a Y address for the X address 222 of each item shown in step 403, first, as shown in FIG. 5, it is determined whether there is any unprocessed item for which the Y address has not been created. (Step 4301) If not, the process ends.

If there is, the index 220 extracts one younger item (step 4302), and determines whether there is an item immediately before the extracted item (an item smaller than the index 220) (step 4302). 430
3) If not, the Y address of the retrieved item is set to "1" (step 4304).

If so, it is determined whether the X address of the immediately preceding item is smaller than the X address of the retrieved item (step 4305). If not, 1 is added to the Y address of the immediately preceding item. The value becomes the Y address (step 4306).

If it is smaller, the value of the Y address of the immediately preceding item becomes the Y address of the extracted item (step 4).
307), and returns to step 4301.

By the above-described processing, the hierarchical address table 22 shown in FIG. 2C is created, and the hierarchical address table 22 creates the hierarchical diagram shown in FIG.

The manufacturing parts table diagram creation process in step 302 obtains information on manufacturing-specific operation steps not managed in the design parts table from the operation step file 23 and displays the information on the display unit 14. This is a process of creating a hierarchy diagram of a manufacturing parts table by dragging and dropping a work process, and creating a manufacturing parts table.

First, as a manufacturing parts table diagram creation process, for example, as shown in FIG.
From the manufacturing BOM, the necessary work process is displayed below the design hierarchy diagram, and the necessary work process is dragged to the manufacturing BOM,
A case will be described in which an operator determines a position to add a work process to and drops the work process at a necessary location, thereby creating a hierarchical diagram of a manufacturing parts list.

As shown in FIG. 8, the manufacturing parts list drawing process first determines whether or not an item is displayed at the XY address of the drop destination of the work process (step 80).
1) If not displayed, an error at the drop destination is set (step 802).

If so, it is determined whether the drop position is on the right or left side of the item (step 803).

If it is on the left side, it is determined whether or not the drop destination item has a parent item (step 804). If not, the process proceeds to step 807. If there is, the configuration file 21 representing the relationship between the parent item and the drop destination is displayed. The record is deleted (step 805), and a record indicating the relationship between the parent item and the dragged work process is added to the configuration file 21 (step 8).
06), a record indicating the relationship between the dragged work process and the drop destination item is added to the configuration file 21 (step 807).

Then, the dragged work process is added to the item file 20 (step 808), the hierarchical address table 22 is recreated (step 809), and a hierarchical diagram / table is displayed (step 810).

In step 803, if it is on the right, the configuration file 21 having the drop destination item as the parent item
Are deleted, the dragged work process is rewritten to a record having the parent item (step 811), and a record indicating the relationship between the drop destination item and the dragged work process is added to the configuration file 21 (step 812). Similarly, the process proceeds to step 808.

It is to be noted that whether or not the drop destination item has a parent item in step 803 is determined as follows: X and Y addresses of the drop destination item are X1 and Y1, respectively. X address <X1 and Y address ≦ Y1 The search is performed by searching for the item satisfying the condition from the back of the hierarchical address table 22. Then, the corresponding first record is set as a parent item to be obtained.

Next, FIG.
As shown in the figure, when the items A and C in the hierarchical diagram A are to be lower than the item B, drag the item A in the hierarchical diagram A and drop it below the item B in the hierarchical diagram B. The parent-child relationship is changed (process moving process) to create a hierarchical diagram of the manufacturing parts list.

As shown in FIG. 10, the manufacturing parts list drawing process first deletes the record of the dragged item and the parent item of the item from the configuration file 21 (step 1001), and deletes the parent item in the drop destination. It is determined whether or not there is an item (step 1002). If so, it is determined whether or not the item is displayed at the drop destination (step 1002).
3) If the item is displayed, it is determined whether the drop position is above or below the item (step 1004). If it is above, the previous record and the drop destination record among the sibling records of the drop destination are determined. With the intermediate value of the sibling sequence as the sibling sequence, a record indicating the relationship between the parent item at the drop destination and the dragged item is added to the configuration file 21 (step 1005).

Thereafter, the hierarchical address table 22 is re-created (step 1006), and a hierarchical diagram / table is displayed (step 1007).

In step 1004, if the drop position is on the lower side, the intermediate value of the sibling sequence of the record immediately after the sibling record of the drop destination and the sibling sequence of the record of the drop destination is set as the sibling sequence, and the parent of the drop destination is set. A record indicating the relationship between the item and the dragged item is added to the configuration file 21 (step 1008),
Proceed to step 1006.

If the item is not displayed at the drop destination in step 1003, the intermediate item of the record immediately before and after the sibling record of the drop destination is set as the sibling sequence, and the item dragged to the parent item at the drop destination is set. Is added to the configuration file 21 (step 1009), and the process proceeds to step 1006.

Thus, the order of the hierarchical table can be automatically changed.

Further, in addition to the above-described processing, the hierarchical diagram editing unit 13 increases the number of items in the hierarchical address table 22 as shown in FIG. If the content cannot be displayed on the
1 is indicated by the symbol of the table index of the hierarchical address table instead of each item code shown in (b),
If you want to see the contents in the frame, specify a specific range (for example, a range of functional units) of the entire hierarchy diagram, and display only the hierarchy diagram in that range on the screen by zooming. It is also possible to display the contents at the same time.

The zoom display at this time is performed by using a rectangular area selection by mouse drag as shown by a dotted line in FIG. 11B.

Here, the XY address of the drag start point is X1, Y1, and the X / Y of the drag end point is X2, Y2 (X
If 1 ≦ X2, Y1 ≦ Y2), a record that satisfies X1 ≦ X address ≦ X2 and Y1 ≦ Y address ≦ Y2 is selected from the hierarchical address table and the item is displayed.

Further, as shown in FIG. 12, the root list file 24 contains a tree base point (X address = 1 item).
(In the example of FIG. 12, the route list file 24a has information of the item A and the route list file 24b has the information of the item D.) The hierarchy is displayed, and the combination (merging) of the hierarchy of each tree is dragged and dropped to create the item file 20, the configuration file 21, and the route list file 24, and the entire route list file 24 is created based on the created route list file 24. It is also possible to create a hierarchical diagram.

Further, as shown in FIG. 13A, by inputting the lead time of each work process to each item in the hierarchy diagram of the manufacturing parts table, the Gantt chart creation unit 15 shown in FIG. 13B. Gantt charts used for scheduling can be created.

Therefore, the manufacturing parts bill diagram creation system for creating a manufacturing parts bill diagram to be used in manufacturing from the design hierarchy parts table is provided to each part based on the data of the item file and the configuration file of the design hierarchy parts table. Hierarchical address table creating means for creating a hierarchical address table having address information when hierarchically displaying, hierarchical table diagram creating means for creating a hierarchical table and a hierarchical diagram using data of the hierarchical address table, Means for allocating work steps required for the production of items to the created hierarchy table and hierarchy diagram to create a manufacturing parts diagram, and the hierarchy table, hierarchy diagram, and manufacturing parts diagram And a display means for displaying a work process for adding a work process necessary for parts manufacturing to the parts list having a hierarchical structure of the design through the display screen. It is possible, it is possible to perform the creation 及-BOM view from BOM easily in a short time.

Further, in order to support the editing work of the manufactured parts table diagram editing means for correcting the created manufactured parts table diagram or changing the manufacturing order,
