運用限制理論需求拉動補貨與緩衝庫存管理改善記憶體模組當日接單當日出貨滿足率

Abstract

記憶體產業是現今電子產業中面臨景氣波動衝擊影響甚鉅的產業之一，緣自各種消費性電子產品的引用,記憶體產品的應用近年來快速走向多元化,結合消費性電子產品的產業特性,產品生的命週期趨向更為短促。供給與需求面的失衡經常引起市場價格的劇烈變動，企業庫存價值損失的風險相對提升。因此供應鏈庫存管理的一直是這個產業營運成敗的關鍵議題。 限制理論的需求拉動與緩衝管理模式(Demand Pull & Buffer Management)，為供應鏈管理提供了不錯的解決方案。本研究運用此供應鏈管理模式，為個案公司發展出符合記憶體模組產業特性的成品庫存控管機制。運用即時成品庫存的資訊來拉動半成品庫存之包裝作業，成功藉由系統評估與系統建置的實務應用，印證此庫存管理模式在面對多變的市場需求，仍能快速反應調整庫存。並運用極短促的補貨週期，將庫存水準控制在更低的合理的範圍。整體而言，除了庫存管理績效評估的改善達到令人滿意的結果，個案公司所強調的單日接單供貨滿足率也獲得明顯的改善。

Currently, the memory industry is one of the businesses faced and influenced with market fluctuation assaulting prosperously in the electronic industry. Since various kinds of consuming electronic products applying the memory storage function, the memory product move towards diversification rapidly in recent years. Combining the industry characteristic of the consuming electronic product, the life cycle of the memory products tend to be shorter and shorter. The out-of-balance between supply and demand caused not only the market pricing fluctuated but increasing the risk of the stock value loss to the enterprise. Thus, it’s always the important subject to enhance the profitability through the inventory control of supply chain management TOC Demand-Pull and Buffer Management is an outstanding and effective model to provide the solution of supply chain management. In this paper we adopted the management model and developed a practical inventory control mechanism for the finish goods. Based on the real-time inventory change information driven, the packing line issues and completes the replenishment orders accordingly. Through the progress of evaluation, realization, and implementations, we confirmed the effectiveness of TOC Demand-Pull and Buffer Management inventory control. Facing the changeable market demand and shorter replenish time requirement in the memory module practice, this inventory control model provides higher fulfillment rate, more flexible, and lower inventory. Meanwhile, the improvement target of the same-day shipping fulfillment rate of the case company is achieved.
