<p>Provided is a precut material allocating method for allocating a plurality of products having a predetermined size to a parent material group composed of a plurality of parent materials of different sizes. The method comprises a sorting step of arraying the plural products sequentially of the sizes, a tentative allocation step of extracting the individual products in the array order and allocating the extracted products tentatively to the individual parent materials belonging to the parent material group, thereby to establish a plurality of tentative allocation states, a first standard step of selecting the tentative allocation state, in which the yield of the parent material used in the allocation is the highest, of the plural tentative allocation states established, as an allocation candidate, and a second standard step of selecting the tentative allocation state, in which the total of the remaining sizes of all the parent materials used for the allocation, of the plural tentative allocation states established, as the allocation candidate. The method further comprises a third standard step of comparing, if predetermined tentative allocation states are satisfied at the first standard step and the second standard step, the selected tentative allocation state and the remaining tentative allocation states, for the tentative allocation states individually selected at the first and second standard steps, thereby to select again the tentative allocation state, in which the total of the sizes of the individual parent materials used is the minimum, as the allocation candidate.</p> |
