Abstract
In a physical distribution model of the circulation type, synchronization is established between a reuse plan and a delivery/fabrication plan to thereby reasonably reduce the excess and deficiency of inventory articles at a confluence point of regenerated reusable articles and newly delivered component parts. With regard to newly delivered lower-level items, predict a variation or fluctuation of stock quantity based on at least a delivery schedule of them and a present stock amount along with usage plans in manufacturing processes. As for lower-level items of regenerated articles, predict a delivery due date and an expected number of such regenerated lower-level items based on at least a stock quantity of recovered items collected for reuse purposes and a lead time for taking regenerated lower-level items out of the collected items, thereby controlling, based on the both prediction results, the stock quantity of the lower-level items in manufacturing processes.
