存貨管理的目的，在於如何用最低的存貨成本來滿足顧客對產品的需求，而存貨決策乃是在決定每次訂購或生產貨品的數量及時間，使能達成存貨管理的目的。然而存貨服務水準和存貨總成本之間亦有著取捨關係。現今，顧客服務的滿足是企業間重要的競爭策略，所以實務上業者追求著是服務水準和成本間的平衡點。 本研究主要是探討流行性商品，其需求量服從羅吉斯分配的前提下，考慮可控制的前置時間內，允許缺貨且缺貨發生時考慮部分欠撥、部分銷售損失與生產過程不完備混合的存貨系統，且再加入服務水準的限制式。提出一個以訂購數量(Q)、請購點®、設置成本(A)、品質水準(θ)和前置時間(L)等的決策變數之存貨模型，並以數值模擬方法推算出服務水準和全年期望總成本之間的關係。

The object of the inventory management is to satisfy the customer demand with minimum inventory cost and the inventory policy is how to decide the quantity or timing of every order times, that can reach the object of the inventory management. However there is a closely-related relationship between inventory service level and the total inventory cost. Now, the services of all customers be satisfied is important competitive policy during business. All operators of the business practice are seeking for the balance point between service level and cost. The research analyzes the inventory model for the logistic demand. In the controllable lead time, the shortages are allowed and the total amount of stockout during the stockout period is considered to be a mixture of backorders and lost sales, then put in the subject of service level. We propose the inventory model of decision variables that includes order quantity、reorder point、setup cost、quality level、lead time and service level etc. Then we utilize the numerical simulation examples to illustrate the relation between total cost and service level.
