本篇論文主要在提出一種考慮允許延後付款及具有存貨持有成本折扣假設下的存貨模型。允許延後付款之條件即指當零售商之訂購量達到供應商所訂定允許延後付款之數量時，供應商始提供零售商一信用交易期限；反之，則不允許延後付款。而存貨持有成本折扣則是指零售商在本身無儲存設備情況下，轉而向外承租倉庫。而若零售商所需儲存之物品數量達到承租倉庫廠商所提供折扣之數量時，即給予存貨持有成本的優惠。本篇論文即是在考慮此兩種因素下，發展成一存貨模型，以使其更貼近實務。
在模式求解方面，本篇論文利用模型推導出其各項成本函數，且在其各項成本函數皆為凸函數之條件下，根據不同的狀況，求出其各函數之最佳解，接著再比較其相對應之各成本函數，得出最小之成本，即得其最小成本解。而後進一步以數值為例，解釋本篇論文中所有推導出情況。
本研究所發展的模式，由於加入了新的考慮因子，將可使傳統經濟訂購數量(EOQ)模型延伸至更接近實務，也使其應用範圍將更為廣泛。

This paper establishes the inventory model under conditions of permissible delay in payments depending on the ordering quantity and discount of inventory holding cost. When the ordering quantity is less than the quantity at which the delay in payments is permitted, the delay in payments is not permitted. Otherwise, the fixed trade credit period is permitted. In addition, if the retailer has no storage facility, then the retailer will rent a warehouse. When the quantity of storage is less than the quantity at which the discount of inventory holding cost is permitted, the discount of inventory holding cost is not permitted. Otherwise, the discount of inventory holding cost is permitted. Consequently, this paper establishes the inventory model under above two conditions, and we hope to approach the practical situation.
In the aspect of solving, this paper use the every cost function that obtained from the model is convex. According to the different case, we compare the different cost function and we get the solving with least cost. Furthermore, numerical examples illustrate all results obtained by this paper.
Because the inventory model that obtained from this paper join the new factors, we can make the economic ordering quantity (EOQ) model more approach the practical situation and make the range of discussion more extensively.
