FIG. 6 is a flowchart showing the processing contents of the product number development unit 16.
[0015]
First, the assembly order registration unit 14 records the operation type and operation time of the assembly operation between parts given to the CAD module 11 in the assembly order storage unit 15 as shown in FIG. 7 (step ST1).
In FIG. 7, operation A represents an operation of reading a part from a database (not shown) and displaying it on the display 3, operation B represents an operation for inputting an assembly command for requesting matching of a plurality of parts, and operation C represents a part. Represents an operation of moving manually. In addition, “10:00” and “4:00” represent times when various operations are performed.
[0016]
When the recording of the operation type and the operation time is completed, the assembling order registration unit 14 searches for the part for which the B operation is performed and the operation time (step ST2).
When there is a part for which the B operation is performed, the assembly order registration unit 14 calculates the difference in the operation time related to the B operation of the part and obtains the absolute value of the difference result (steps ST3 and ST4). ).
In the example of FIG. 7, in the case of component {circle around (1)}, the absolute value of the difference result = | 4: 00-0 (blank) | = 4, and in the case of component {circle around (2)}, the absolute value of the difference result = | 4: 00— In the case of 6: 00 | = | −2 | = 2 and component {circle around (3)}, the absolute value of the difference result = | 0 (blank) −6: 00− | = | −6 | = 6.
When obtaining the absolute value of the difference result, the assembly order registration unit 14 recognizes that the parts having the smaller absolute values (part (2), part (1), part (3)) are assembled first (step ST5). ).
[0017]
When there is no part for which the B operation is performed, the assembly order registration unit 14 searches for the part for which the C operation is performed and the operation time (step ST6).
When there is a part for which the C operation is performed, the assembly order registration unit 14 recognizes that the part with the earlier operation time of the C operation is assembled first (steps ST7 and ST8).
Further, when there is no part for which the C operation is performed, the assembly order registration unit 14 searches for the part for which the A operation is performed and the operation time (steps ST7 and ST9).
When searching for the operation time of the A operation, the assembly order registration unit 14 recognizes that the parts with the earlier operation time are assembled first (step ST10).
[0018]
The product number development unit 16 of the data processing apparatus 1 stores the assembly order registration unit 14 in the assembly order storage unit 15 when the assembly order registration unit 14 recognizes the assembly order of the parts as described above and stores it in the assembly order storage unit 15. Part numbers are assigned according to the assembly order of the parts.
