<p><P>PROBLEM TO BE SOLVED: To solve a problem that high-accuracy material ordering can not be performed by the occurrence of delivery delay of slave components to a product manufacturer since a slave component manufacturer makes a mistake in reading variations. <P>SOLUTION: Information relating to the quantity of materials in stock that a slave component manufacturer has, is held at a product manufacturer side and when ordering a slave component from the product manufacturer to the slave component manufacturer, the quantity of slave components scheduled to be next ordered calculated by the product manufacturer is described in an order statement and reported to a vender. At the same time, materials required for manufacturing the slave components to be ordered are supplied, and the quantity of supplied materials is held as theoretical stock for each slave component manufacturer. When the ordered slave components are delivered to the product manufacturer, the quantity of required materials is calculated again from the quantity of delivered slave components, and subtracted from the theoretical stock and when next ordering slave components, the quantity of materials required for manufacturing the slave components is first calculated from the slave components to be ordered similarly to the last time. When supplying the required materials, materials are supplied for the quantity subtracting a numerical value of the theoretical stock. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
