摘　　要：以定购次数必须为整数这一客观条件为前提,在Kohli和Park提出的含数量折扣的买-卖两方多商品联合定购模型基础上,构建了一个更真实、更科学的改进模型,分别对数量折扣策略下多商品单独定购和联合定购时两级供应链成本组成进行了分析,并求出两种定购情况各自所对应的最优每次定购数量;最后用模拟算例描述了改进模型的运算过程,并证明了联合定购相对于单独定购可以节约供应链总交易成本。Taking it for granted that ordering times is an integer, this paper establishes an improved model based on Kohli and Park＇s model for coordinating buyer-seller transaction of multiple products with quantity discounts. The improved model is employed to analyze the cost components of two-echelon supply chain with quantity discounts under respective ordering policies and joint ordering policies, which leads to optimal per-order quantity for each case. An example is used to demonstrate the improved model with the conclusion that total transaction cost is reduced.
