半導體製造為資本密集且高度競爭的高科技產業,為了維持競爭優勢,如何提升生產力以更有效地運用各種投入資源成為各企業重要的課題。本研究以紫式決策分析架構和資料包絡分析法為基礎,建立半導體跨廠績效評估模式,使用多項製造指標以衡量各廠之相對效率,並以臺灣某半導體公司之晶圓廠為實證以檢驗效度,並結合領域專家的知識,給予各項指標改善的方向與建議,以提昇跨廠資源分配的決策品質。本研究以實例說明生產規模與生產績效之間的變化趨勢,分析各廠所面臨的優勢與弱勢指標,研究發現藉由企業內部廠際間的評比,可以幫助管理者瞭解各個決策單位執行狀況,並作適當地資源配置,設定改善的方向與幅度,實證研究已驗證本研究之效度與可行性。
Semiconductor manufacturing is very capital intensive and competitive. It is important to optimize the utilization of various resources to generate the outputs efficiently for maintaining competitive advantages. This research aims to conduct data envelopment analysis based on UNISON framework for inter-fab performance evaluation with multiple indices from the constructed objective hierarchy. An empirical study was conducted with real data collected from a leading Taiwan semiconductor company to estimate the validity of the proposed approach. The results can support the decision maker to determine the improvement directions for appropriate resource allocations and thus demonstrate the practical viability of the proposed approach.
