PROBLEM TO BE SOLVED: To create an equal division plan in a practical time regardless of the nature of a problem to be solved.SOLUTION: A vertex is made to correspond to a slab group in order to solve an optimization problem for minimizing an objective function value of aiming to reduce the total number of divisions and reduce the number of making divisions, and two slab groups corresponding to two vertices mutually connected by branches are represented as a candidate of two slab groups piled up on the same dispensing peak. Then, the total number of creeks is represented as the total number of divisions, and the total number of branches between the two branches corresponding to the two slab groups for establishing reverse relationship are represented as the number of making divisions (number of reverse).SELECTED DRAWING: Figure 2
