<p><P>PROBLEM TO BE SOLVED: To ensure effectiveness of production in a processing line and reduce inventory volume of processing parts. <P>SOLUTION: A processing line 2 as a front-end process of an assembly line 1 of an engine, for example, processes a plurality of parts for engines. A change of processing tools is needed by some of the changes in kinds of processing parts. Stock amount of processed parts and an amount of processing parts in the processing line 2 are taken as processing stock (43). An inventory lead time (44), which is the time given until the processing stock comes to zero, is decided by the processing stock (43) and a production plan (52) including production order in the assembly line 1. An appropriation instruction control part 21 instructs appropriation of the processing parts of the kind with the shortest stock lead time in principle out of a plurality of the processing parts (or their materials). The control part instructs continuous appropriation of the predetermined quantity of the processing parts constituting a group which does not need a change of processing tools. <P>COPYRIGHT: (C)2004,JPO</p> |
