Abstract :
In order to evaluate the effect of express lots on production dispatching rule scheduling and cost, we applied the event-driven simulation analysis to a real final test facility of one-chip microcomputer. Simulated results show that when the dispatching rule in the express lot assignment is changed from usually used FIFO rule to JIG+RPM rule, the allowable percentage of express lots in total arrival lots increases from 15% to 55%. In JIG+RPM rule, the time required for jig exchange and for temperature change, and also the remaining processing time of the machine in use are considered
