Next, referring to the storage contents (FIG. 6) of the production plan / arrangement instruction related information storage unit 36, the 10
It can be seen that, by changing the order quantity of the month 2 from 20 pieces to 0 pieces, the order quantity of the part D on October 3 also changes from 20 pieces to 10 pieces, which has an effect. Similarly, 1 of part A
The production plan for October 3 and October 4 is also reduced from 10 to 0
It turns out that you have to change to individual.

Further, the order for arranging the part G is
By changing from 0 to 20 parts 1
It can be seen that the order quantity on October 4 and the order quantity on October 4 for part F must be changed from 20 to 10, and from 10 to 0, respectively. Similarly, it can be seen that the production plan for the part B on October 5 and the production plan for the part C on October 5 also need to be changed from ten to zero.

On the basis of the results shown in FIG. 8 obtained in this way, the operator operates the input device 1 to cause the production plan change section 24 to change the production plan stored in the production plan storage section 33. .
