限制理論緩衝管理之加強研究

Abstract

在傳統的供應鍊中，傳統的補貨模式是利用預測以及推式管理的方式，常造成供應鍊中的庫存堆積，或是缺貨等無法反應需求變動之情形。為了解決這個問題，TOC提出了Demand-Pull以及Buffer Managements存貨管理模式來降低庫存及提高對需求變動的反應，但Buffer Managements存貨管理模式常會因為假性需求等原因造成庫存的過高，因此為解決存貨偏高的問題，此研究探討Buffer Managements存貨管理模式在實務運作上會遇到的問題，並針對這些問題對Buffer Managements存貨管理模式進行改良，最後驗證了改良之Buffer Managements存貨管理模式比改良前的模式更可以降低庫存水準，同時避免缺貨的發生。

In the traditional supply chain management, we use forecasting and push management to control the inventory, which causes the stock to pile up and the inventory can’t reflect the fluctuation of the actual demand. To solve this problem, TOC proposes Demand-Pull and Buffer Management to reduce the inventory. However, Buffer Management often causes high inventory level. To reduce the stock level, this research discusses the problems which occurred when using Buffer Management in practice. Furthermore, we improve Buffer Management by solving these problems. At last, this research create a computer program and simulate various of scenarios to proves that the improved Buffer Management will decrease the inventory and have fewer shortages than the original one in all circumstances.
