  • Patent number: 7624043
    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.

  • Patent number: 7262766
    Abstract: An apparatus and method for producing an exploded view of an assembly. The invention includes an input unit, a geometrical data memory for storing geometrical data of parts composing an assembly, a/m for storing assembling process data composed of parts to be attached and attaching directions, a calculating unit for displaying the assembly to a display based on geometrical data, and apparatus for determining arranged positions of the parts in a disassembled state based on assembling process data and geometrical data, thereby producing an exploded view of the display corresponding to the arranged positions.
