And a previous work color 305. Work plan file 7
Is the work number 3 for each data as shown in FIG.
06, limited machine number 307, work time 308, scheduled start date 309, color 310 and decision section 1, each data represents each work, and is arranged in order of priority of each work.
Calendar file 8 Working day 40 as shown in Figure 4 (a)
1s are arranged in order from the earliest one. As shown in FIG. 4B, the work instruction file 9 has a work number 402, a machine number 403, a color 404, a work start date 405, and a work start time 406.

Next, the operation of this embodiment will be described with reference to FIG.

First, the present apparatus operates by issuing a molding machine allocation plan execution instruction from the input means 1. First, the previous work management data is transferred from the previous work management file 6 to the machine number selection means 3 (step 201). In the machine number selection means 3, the last work management data is stored as the last work end date 30.
3. Sorting is performed in ascending order at the last work end time 304 (hereinafter referred to as the last work end date and time) (step 20).
2). Next, the data with the smallest work end date and time of the previous time is extracted and passed to the work number assigning means 4. For example, in FIG.
In the case of (a), the data 2 with the smallest work completion date and time last time
Is transferred to the work number assigning means 4 (step 20).
3).

Next, the operation of the work number assigning means 4 will be described.

First, the work plan file 7 is searched for a limited machine number 307 (machine number for dedicated work) which is the same as the machine number 301 in the previous work management file 6 in descending order of work priority. At this time, the data in which the section “1” indicating the determined state is set in the determined section 311 is skipped. For example, the data 2 in FIG. 3A is the work number assigning means 4
When it is delivered to the machine, since the machine number 301 is "2", the limited machine number 307 is searched by "2" (step 204).

Limited machine number 307 which is the same as machine number 301
When it is possible to search for, the work number 306, the color 310, and the work number allocating means 4 output the machine number 301, the last work end date 303, and the last work end time 304 to the work instruction file 9. For example, in the case of the data 2 in FIG. 3A, the data 4 is retrieved in FIG. 3B and is output to the work instruction file 9 like the data 1 in FIG. 4B (step 205). At this time, the last work end date 303 and the last work end time 304 are set as the work start date 405 and the work start time 406 in the work instruction file 9.

Next, in the previous work management file 6, the previous work number 302 is set to the work number 306, and the previous work color 305 is set.
Is updated to the color 310, and the previous work end time 304 is updated by adding the work time 308. Last work end time 304
If the added result of is greater than or equal to "24", "24" is subtracted from the added result and updated, and the previous work end date 303 is added to the calendar file 8 that manages the working days.
Positioning is performed and the previous work end date 303 is updated with the next working day 401. Further, the decision division 311 of the work plan file 7 is updated to "1". For example, when updating the data 2 in FIG. 3A with the data 4 in FIG. 3B, the previous work number 302 is updated to “d” and the previous work color 305 is updated to “B”. When the work time 308 is added to the previous work end time 304, the result becomes "28".
04 is updated, and the last work end date 303 is "190062".
Since it is 6 ", it is first positioned in the data 2 of the calendar file of FIG.
27 "is used to update the last work end date 303. Also, FIG.
The decision division 311 of the data 4 in (b) is updated with "1" (step 206).

Limited machine number 307, which is the same as machine number 301
Is not found, the same color 310 as the previous work color 305 is searched from the work plan file 7 in descending order of work priority. At this time, as in step 204, the decision division 31
The data for which the division "1" is set to 1 is skipped. For example, when the data 3 in FIG. 3A is transferred to the work number assigning unit 4, since the previous work color 305 is "OR", the color 310 is searched by "OR" (step 20).
7).

If the same color 310 as the previous working color 305 can be retrieved, steps 205 and 206 are performed.

When the same color 310 as the previous work color 305 cannot be retrieved, the data having the highest work priority in the work plan file 7 is extracted and the work number 306, the color 310 and the work number 306 extracted into the work instruction file 9 are extracted. Work number allocation means 4
Output the machine number 301, the last work end date 303, and the last work end time 304. For example, when the data 1 of FIG. 3A is transferred to the work number assigning means 4,
In (b), the limited machine number 307 and the color 310 have no data matching the search conditions, so data 2 having a higher priority of specialization is extracted except for the data 1 whose determination category is "1", and the work instruction file 9 Is output as to the data 3 in FIG. 4B (step 208). Then, step 206 is performed. The above operation is repeated until all the decision categories 311 of the work plan file 7 become "1". For example, the operation is repeated until the result shown in FIG. 5B is obtained (step 209).

Finally, the output means 10 outputs the work instruction form from the work instruction file 9 (step 21).
