摘　　要：大部分零售企业在向供应商订货时,会同时面临有限订货容量和订货价格折扣这两类问题。这里,考虑一个具有有限订货量和价格折扣的多阶段定期盘点库存系统。假设当且仅当订满订货容量时,企业才能够享受到订货单价折扣的优惠。基于动态规划法,构建该系统的模型。在此基础上,引入强CK-凸函数的概念。借用此概念和相关性质,开发出使得总期望折现成本最小化的最优订货策略。When ordering from the suppliers, most retailers would meet finite ordering capacity and discounted price. Here, consider a period review inventory system with finite ordering capacity and discounted price. Suppose only when ordering full capacity would the retailer place an order with discounted price. Based on dynamic programming, establish the model. Then introduce the definition of strong CK-convex. According to the definition and properties, develop the optimal ordering strategy to minimize the total expected discounted cost.
