摘要

在產能相繼擴充、製程技術提高的情況下，半導體產業為了爭取客戶的訂單，各廠商莫不提高訂單調整的彈性。容許客戶調整所下訂單之內容，會造成產品組合在短期間內產生異動，此一情形，無疑對過往假設產品組合比例固定情況下之研究成果，產生一重大的挑戰。基於此，本文在保障系統其餘客戶不受到過多幹擾的前提下，提出「產品組合更動之快速生產規劃機制」，透過系統化的分析流程，分別構建「目標規劃模組」、「產能需求評估模組」、及「整體績效評估模組」，藉由此三個模組環環相扣的配合，進行產品組合更動後之各項規劃、決策工作。實驗結果顯示，本文所提之快速生產規劃機制，除了能使生產系統的達交績效不受到影響外，對於異動訂單亦能設定一個可行的交期；此外，由於「產能需求評估模組」以對瓶頸機種與關鍵機種之產能負載進行良好控制，使製造系統因為產品組合比例轉換所造成的衝擊降至最低。上述種種，展現本文於實際應用上之可行性與有效性。

Due to supply over demand, the wafer fabrication industry in Taiwan became dramatically competitive. Providing more service or flexibility for customers is very important for manufacturers. Among them, flexibility in order changeover for customers is one of key issues. This paper develops a rapid production planning mechanism, containing three modules, for reacting product mix changing problems. When product mix change is requested, the target planning module updates the performance targets (product cycle time, throughput, order due date) with an analytical method. Then, capacity demand evaluation module monitors the loading of bottleneck and capacity-constrainted resources (CCRs) by order-oriented scheduling method so as to prevent bottleneck from shifting. Finally, integrated performance evaluation module evaluates the difference in the profit making and in system slackness that induced from the changing of product mix. The case study showed that the rapid production planning mechanism not only achieved the system targets, but also set an achievable due date for these changed orders. It also decreased the impact from changing product mix, since the loading of bottleneck and CCR machine were controlled in the capacity demand evaluation module. The rapid production planning mechanism proposed hence is effective and efficient for wafer fabrication.
