綁機情境之MTO/MTS半導體廠派工

Abstract

晶圓代工廠生產型態為訂貨生產(make-to-order︰MTO)，當訂單不足時，會以生產存貨生產類型的產品，來維持機台的高利用率。本研究針對綁機情境下MTO/MTS混製生產情境，提出了一套派工法則，以達到MTO產品高達交率及MTS高產出為主要績效指標。經由模擬實驗驗証，本法則確實較過去文獻所提的法則有較佳的績效。

A semiconductor foundry is essentially a make-to-order (MTO) factory. However, when there is no enough order, a foundry may product some make-to-stock (MTS) products to maintain high utilization of machines. This research proposes a scheduling rule for a MTO/MTS semiconductor fab with machine-dedication characteristics. The scheduling rule aims to achieve high hit-rate (on-time delivery rate) for MTO products as well as high throughput for MTS products. Simulation results show that the proposed scheduling rule outperforms some other representative rules in literature.
