PRODUCTION PLAN MAKING PROGRAM, DEVICE, AND METHOD

摘要

A production plan enabling suppression of occurrence of excess stock is made. A shipping request representing the requested amount of shipping for each shipping request week is received.  Among the shipping weeks of the shipping requests, the furthest future shipping request week is handled as the furthest future shipping week, and the amounts of shipping of shipping weeks near the present time are determined sequentially from the amount of shipping of the furthest future shipping week.  For the shipping requests of the unset shipping among the shipping requests after the shipping week n for which the amount of shipping is to be set, the order setting time which is the time of period till the products are delivered to the shipping destination is determined.  The allocation order 1, 2,... is determined for each of the shipping requests of the unset shipping so that the longer the order setting time is, the higher the order of allocating shipping request is.  In the allocation order, the requested amounts of shipping for the shipping requests of the unset shipping are allocated sequentially to the shipping week n until the amounts of shipping reach the production capability (1300) of the product.  When the amounts of shipping exceed the production capability, the excess over the production capability is handled as the amount of unset shipping, and the amount is allocated to the shipping week (n-1) and so forth before the shipping week n.
