  • Patent number: 7783531
    Abstract: A container stock management technique in a hospital and a culture center is provided. A stock management device (1) manages both transfer (outgoing transfer) of cells sampled at the hospital to the culture center, and transfer (incoming transfer) of the cells cultured from the sampled cells at the culture center, to that hospital, with one working code. The ID of containers used individually for the outgoing transfer and the incoming transfer are made to correspond to an identical working code. The optimum transfer route including the procurement of containers is determined by examining the container stock in each of the hospital and the culture center.

  • Patent number: 7660753
    Abstract: In a safety stock control system, safety stock is changed in response to updating of a setting value so as to be continuously maintained as a proper value. The safety stock control system is comprised of a demand prediction means, an actual value calculating means, a predicted remainder calculating means, a parameter calculating means, and a safety stock calculating means for calculating safety stock based upon a parameter calculated by the parameter calculating means. In response to updating of the setting value, data of an area, which is different from such a data read when a plan is made, is temporarily read from a data storage means to the respective means, and then, various sorts of calculating process operations are carried out either one time or plural times.

  • 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.

  • Publication number: 20090138327
    Abstract: This invention relates to a technique for enhancing the accuracy of sale quota information used in allocation for reservation of a delivery date reply to thereby shorten a sale-quota reply response time. Disclosed herein is a delivery date reply system which permits preallotment of a sales quota of a sellable distribution item and which is responsive to receipt of a delivery date inquiry for allocating for reservation the content of such inquiry from within the sale quota to thereby reply a delivery date and, when the inquiry content is not allocated to the sale quota, issues a reply as to a delivery date after having performed sale quota alteration simulation for alteration to a sale quota with maximal satisfaction of a customer's desired delivery date, quantity and item contents.

  • Patent number: 7508983
    Abstract: According to a region dividing device, a region dividing member generates a plurality of primary region groups, each of which includes a plurality of primary regions. Each of the plurality of primary regions is characterized by each measured value of feature values. A basic region group generating member generates a single basic region group that includes a plurality of basic regions produced by dividing the target image. Each basic region is characterized by each measured value of feature values. Each measured value is obtained based on the measured values of the plurality of primary regions of the plurality of primary region groups. A region integrating member integrates similar adjacent basic regions into a corresponding integrated region, based on a weighted Euclidean distance between the similar adjacent basic regions.

  • Patent number: 7092775
    Abstract: The invention proposes a method for devising a production plan of a product to be produced through multiple production steps having different characteristics in a supply chain across multiple companies and/or multiple factories. The method divides a production step of the product into multiple production steps in advance based on a constraint to be considered when the production plan therefor is devised, defines identifiers for the multiple production steps, prestores the defined identifiers in a storage portion as step identification information, and prestores step information having at least correspondences between the production steps and items.
