<P>PROBLEM TO BE SOLVED: To reduce an element rank inventory, for example a non-defective inventory left from combination but not for sale, as well as reduce a delivery (delivery date) risk by optimizing entire production including an inventory for production across multiple production sites (processes), for example optimizing a rank derivation rate of a proceeding process according to a shipment plan of a last process. <P>SOLUTION: A system controls a light-emitting property of a chip element, and a light-emitting property and a light-emitting amount of a phosphor (resin composition) to optimum values as element production parameters so as to use a rank inventory 111 of an LED element production process 11, and digests the remaining rank inventory 111. <P>COPYRIGHT: (C)2012,JPO&INPIT |
