摘　　要：考虑由一个制造商和一个零售商组成的易逝品供应链,在销售努力水平及退货价格与需求及退货具有相关性的前提下,建立了易逝品供应链的弹性数量契约模型,指出单纯的弹性数量契约无法实现供应链协调,而基于回馈与惩罚契约策略下的弹性数量契约能够实现供应链协调,并给出了供应链协调下的模型优化方法;最后,以数值实例计算了易逝品供应链协调下的最优销售努力水平、最优退货价格和最优订购量,并分析了各种参数的变动对最优退货价格、最优销售努力、最优订购量和集成式供应链最优利润的影响.A perishable product＇s supply chain consisting of a manufacturer and a retailer is considered in this paper, on the premise of retailer＇s effort and return price dependent demand and false failure return, the mathematical models of quantity flexibility contract is established, pointing out that just one quantity flexibility contract can not coordinate the supply chain with effort and return price dependent demand and false failure return, but the quantity flexibility contract based on rebate and penalty can carry out perishable product＇s supply chain coordination, and giving parameter method for optimal contract. Finally, a numerical example is given to illustrate the model and the solution process, and analyzing the impact of parameter＇s change on the optimal return price , the optimal effect ,the optimal inventory and the integrate supply chain＇s optimal profit.
