In this example, the set required stacking shape KSB has a rectangular shape, and the minimum rectangular shape including all the stacked plate member parts W is used as the set required stacking shape KSB.
Regarding the plate material set SC, since the plate material component W included is only one plate material component WSC1, the shape of the plate material component WSC1 becomes the required loading shape KSC for each set.
In addition, when the remaining plate material parts WSA2 and WSA3 can be stacked without protruding within the range of the maximum plate material component WSA1 as in the plate material set SA, or the plate material component W belonging to the plate material set SC is the plate material. Even when only one component WSC1 is provided, the minimum rectangles including the plate material components WSA1 and WSC1 may be used as the set required loading shapes KSA and KSC, respectively.

The area nesting means 25A nests the stacking areas R1 and R2 to be stacked by the set required stacking shapes KSA, KSB, and KSC thus determined. For example, as shown in FIG. 6D, set-by-set loading areas RSA, RSB, RSC, which are the loading areas of the individual plate material sets SA, SB, SC, are determined.
