Yet, previous studies on lot dispatching focused on some other relevant performance indices, but very few directly focus on the raising on hit rate. This research aims to develop dispatching algorithms for raising the hit rate of semiconductor fabs. Some popular dispatching rules are first examined by discrete event simulation. Results show that CR (critical ratio) dispatching rule exceeds the others. This research proposes three novel perspectives to enhance the CR dispatching rule. The hit rate performance of the enhanced-CR rules and some significant dispatching rules in literature are compared by simulation, in scenarios varying in product mix and fab loading. Simulation results show that DCR(delay critical ratio), one of the enhanced-CR dispatching rules, outperforms the others. Muh-Cherng Wu 巫木誠 2003 學位論文 ; thesis 41 zh-TW |
