摘　　要：文章基于差异化产品的竞争背景,建立了一种差异化产品竞争和采购价格时变的EOQ模型,运用博弈的理论求解出模型最优解,并给出了数值算例和主要参数的灵敏度分析。研究表明,差异化产品的售价和竞争程度在不同的阈值范围内,决策变量对销售商利润的影响不同;异质品的价格和服务敏感因子、顾客等待时间敏感因子的增加,会分别造成差异化产品的短缺量拖后率降低,故销售商需减少缺货时间或增加产品期初库存量来获得最大平均利润。Based on the competitive background of differentiated products,this paper establishes a time-varying economic order quantity(EOQ)model of differentiated product competition and purchase price.The optimal solution of the model is obtained by game theory,and numerical examples and sensitivity analysis of main parameters are given.The results show that the price and competition of differentiated products are within different thresholds,and the influence of decision variables on the profit of retailers is different;the increase of price and service sensitive factors of heterogeneous products and customer waiting time sensitive factors will reduce the backwardness rate of differentiated products,so the sellers need to reduce the backwardness time or increase the stock of products at the beginning of the period to obtain the backwardness rate maximum average profit.
