本研究主要在探討一對一通路結構、有限多期環境下，買方之批量決策問題。傳統的存貨問題一般都未考量產品的自然損耗性及供應商產能限制對買方在制定購買決策時造成的影響。本研究將發展出一個考量缺貨、產品損耗性、缺貨待補率及每期訂購數量限制的批量決策方法。我們以華格納懷丁法(Wagner-Whitin approach)為基礎，在考量缺貨、產品損耗性(Deterioration)的前提之下，發展求解最低總成本之最佳訂購期及訂購數量之動態批量方法。其後，考量到現實環境中缺貨常帶來銷售機會的損失將缺貨待補率的觀念加入演算法之中；另外，供應商之每期產能能力關係到買方單期所能訂購之量，因此我們也將產能之限制加入演算方法之中。我們將分別討論需求之發生為離散及連續之下的演算方法，並將演算方法以數據代入，以敏感度分析的方式分析各項成本變動對於總成本及訂購政策所造成的影響。

The purpose of this study is to develop an optimal replenishment policy for deteriorating inventory in a single-level MRP system with shortage and capacity constraint of supplier. We will develop an optimal dynamic lot sizing method base on Wagner-Whitin Approach. We will develop an optimal dynamic lot sizing method of discrete demand in chapter 3 and continuous demand in chapter 4 respectively. From our numerical analysis it is demonstrated that buyer’s total cost and replenishment policy are influenced by capacity constraint of supplier.
