摘 要
就存貨研究的領域而言，不同之情境具有不同之存貨模式。 企業的存貨管理者所面臨重大問題之一，就是該如何有效地控制及管理有限壽期的產品，或稱為易腐壞性產品的存貨；甚至於我們亦可將產品的過時性歸於此類。
本研究針對這類有限壽期之產品，提供兩種情境存貨模式。其一為在無限時間下且考量物價膨脹﹝即金錢之時間價值﹞之狀況，如何以折現的觀點在最低總成本下取決適當之訂購量與購置決策期程；其二為對於一般壽期較短之產品，當其壽期將盡之際，但新壽期產品業已上市，故對原壽期產品採取降價促銷的作法，使得成本損失降至最低的狀況下，如何取決適當之訂購量與促銷期程。文中除了數學式之推導外，最後並以範例數據載入電腦計算。
關鍵詞：存貨、易腐壞性﹝有限壽期﹞產品、折現、促銷

ABSTRACT
In Inventory researching field, different situations there are different inventory models. The enterprises inventory managers
have to face one of the most important problems is how to control and manage products with limited life, or we can also called
deteriorating products. Even include the out-0f-date products.
In this research we provide two kinds of inventory models for these limited life products. The first is over an infinite plann-
ing horizon for a deteriorating item taking account of time value of money. How to decide the appropriate order quantity and order
period that keeps the total cost lowest? The second is for those sho rter life cycle products, when their life is almost exhausted but the
newest products are provided in the markets already. Therefore we have to reduce the price for promoting these older products in order to keep the cost loss minimum. How to decide the appropriate order quantity and the promotion period that keeps the total cost loss lowest? Numerical examples are included to illustrate the model and solution procedure in this composition.
