  • Publication number: 20180315009
    Abstract: The invention is directed to an inventory analysis device that analyzes whether one of a warehousing side and a releasing side causes an inventory of a target article to what extent. The inventory analysis device includes a warehousing-induced quantity calculating portion that calculates, from information on warehousing of the target article, an inventory fluctuation quantity caused by the warehousing; and a releasing-induced quantity calculating portion that calculates, from information on releasing of the target article, an inventory fluctuation quantity caused by the releasing.

  • Publication number: 20180107961
    Abstract: In a supply chain, an optimal task logic is automatically presented in accordance with a status change occurring in each enterprise in a short time. A task support system generates scenario information of a simulation and generates task logic combining information by combining the scenario information and the task logic of each enterprise. Then, KPI information for each task logic in a scenario is calculated by performing a simulation based on the task logic combining information. Next, status change information relating to a task is read, and a search for a scenario closest thereto is performed. Then, a scenario closest to the status change information is referred to, a KPI relating to the scenario from the KPI information is acquired, a scenario achieving the input importance KPI most is acquired, and a task logic that is combined with the scenario in the task logic combining information is calculated as an optimal task logic.

  • Publication number: 20150379466
    Abstract: A BOM of a product which is used at a plurality of sites is acquired from a BOM input unit. With respect to each component configuration in the BOM, specifications with variations in past demand at or above a given level are accepted as variation specification information. On the basis of the variation specification information, the component specification to be segmented is extracted from the BOM and a BOM to be changed is generated. On the basis of the BOM to be changed, the component configuration of the BOM is segmented and reconfigured, a changed BOM is generated, and the changed BOM is outputted.
