Abstract:	在競爭激烈且交易變動快速的商業行為中，為提高零售商的訂貨意願及訂貨數量，供應商往往會提供一些獎勵的策略，如給予延遲付款的寬限期。零售商只要在寬限期內支付貨款就無須負擔任何額外的費用。然而，供應商在提供此項優惠時並非完全沒有任何條件；一般而言，供應商會要求零售商必須訂購一定數量的貨品才能享受此優惠。本研究針對非即時退化性產品，探討當供應商針對各種寬限期訂定不同的訂購數量限制下，零售商該如何擬定最佳訂購策略，才能使得存貨系統的單位總利潤最大。首先，建構一滿足上述狀況之數學模式並求解；其次，深入討論此最佳策略的特性；最後，以數值範例來驗證說明此最佳策略及其相關性質。 In today’s competitive business transactions, to encourage the retailers to buy more, the supplier may provide a permissible delay to his/her retailers if the order quantity is large. Thus, the supplier makes a predetermined quantity and offers a trade credit period. The retailer is allowed a permissible period to pay back the cost of products bought without paying any interest if the order quantity is larger than the predetermined quantity. This study will develop an inventory model for non-instantaneous deteriorating items under a situation in which the supplier provides the retailer various trade credits linked to order quantity. Based on the above conditions, we establish a mathematical model to find the optimal ordering policy for maximizing the retailer’s total profit. Moreover, the characteristics for the optimal solution are discussed. Finally, the models proposed are illustrated through numerical examples and sensitivity analysis is reported.
