Isi artikel

A multistage serial production system that produces a wide-range of final products from the same raw material is considered. The product specification of an order is given by the combination of operation types conducted at each stage, and thus it is possible to start production without confirmed orders. Generally, a single order requests multiple items with a common product specification. Major or minor setup time is incurred when an item to be processed next requests a different specification from the previous item. Because of the significant setup times, a cyclic production rule is introduced in every production stage. Policies for preparing the make-to-stock items in terms of quantity and position are proposed and evaluated in the numerical experiment. The simulation results indicate that limiting the make-to-stock quantity is undesirable and keeping items in upstream buffers is an appropriate action to improve the matching performance. By increasing the desirable quantity of make-to-stock items, the average lateness is improved because of the increase of successful matching.
