| Popis: | 102 This research studies the daily job release policy for a semiconductor wafer fab, operating in a scenario which involves both MTO (make-to-order) and MTS (make-to-stock) orders. The objective of the job release policy is to minimize the work-in-process (WIP) deviation of the bottleneck workstation, in order to reduce the deviation of cycle time. Four heuristic methods (M-1, M-2, M-3, and M-4) are developed in this study and justified by a simulation program coded in Flexsim (proprietary discrete event simulation software). Simulation results indicate that method M-1, by the ANOVA test, significantly outperforms the other three ones. |
