摘　　要： 以订货批量和安全系数为变量,建立了在给定的服务水平约束条件下,安全系数变化时的最优库存决策模型。由模型的分析知,所建立的模型是一个凸规划问题,存在唯一的最优解,并且给出了模型的求解算法,最后通过一个算例说明了模型和算法的有效性。 The inventory control problem when taking account of service level constraints has been investigated in this paper. Under the condition that the order quantity and the safety factor are both treated as variables, an optimal inventory control model is established as the safety fac- tor changes and the inventory system is subjected to service level constraints. It can be proved that the proposed model is a convex programming problem and there is only one optimal solution, and the： solution algorithm is also given. Finally, the effectiveness of the model and the algorithm provided in this paper is validated with a numerical example.
