本研究鑑於450mm晶圓廠時代的來臨，晶舟重量的增加，使得自動化物料搬運系統(AMHS)的相當重要。過去幾年當中，有學者指出AMHS的實施與操作已被認定為影響300mm和450mm晶圓廠過渡期關鍵因素之一。由於連續型搬運系統可以提供晶圓廠AMHS更好的運輸能力，致使成為下一個的晶圓時代的潛力運輸工具。為了提升晶圓廠的整體績效表現，降低批量的搬運時間，本研究找出系統的瓶頸，藉由加快瓶頸迴路的速度，並且配置一般批量的捷徑，調度規則是使用Wang et al. (2016)所提出的啟發式的搶先調度規則(Heuristic Preemptive Dispatching Method, HPDB)，使緊急批量相較於一般批量擁有較高的處理優先權，利用模擬所欲模擬之生產情境，之後與Wang et al. (2016)的HPDB模型比較。最佳的模擬結果為瓶頸速度2英尺/秒的，3條一般批量捷徑的配置下，緊急批量平均搬運時間減少6.57%，一般批量平均搬運時間減少10.53%。

According to the weight of 450mm wafer cassette increases, the weight of a wafer cassette increases. AMHS (automatic material handling system) becomes more and more important. In the past years, some researcher has identified the implementation and operation of an AMHS as one of the critical factors that will affect the transition to 300 Prime and 450mm wafer fabs. The continuous handling system provides 450mm fab AMHS with a better transport capacity, and becomes potential transport of the next generation. In order to improve the overall performance of fab and reduce transport time of wafer, this study concentrated on bottleneck loop. The model provides an effective way by accelerating the speed of bottleneck loop, and setting the configuration of lots shortcut. The dispatching rules using heuristic preemptive scheduling rules (HPDB) which was proposed by Wang et al. Experimental results demonstrate that that in the best case where the number of shortcuts is 3 and the speed of bottleneck is 2 ft/s. Comparison with HPDB, the method reduces the average delivery time by 6.57%, for hot lots and 10.53% for normal lots.
