摘　　要：由于生鲜食品具有易腐性、时鲜性、损耗性等特点,其供应链库存问题成为管理的难点.考虑了生鲜食品供应商和零售商的保鲜努力水平,对基本变质库存模型进行了改进,构建了生鲜食品价格和新鲜度因素影响下的时变需求率;考虑收益共享比例和成本共担比例两个合作参数,并在连续时间背景下采用变分法建立了联合库存控制和分散库存控制两种模式下的供应链库存控制微分对策模型,通过求解发现当约束方程组有解时Nash均衡存在.最后通过数值仿真,比较了两种库存控制模式下供应商和零售商的保鲜努力水平、库存水平以及供应链总利润变化情况,并给出了相应的建议.Due to the perishable,fresh,deteriorating characteristics of fresh food,the inventory control of the fresh food supply chain is a strain for management.The fundamental metamorphic inventory model was improved,considering the preservation efforts of supplier and retailer,and prices and freshness factors affecting time-varying demand rate was built.Revenue sharing parameters and cost sharing parameters were considered,and the variational method was used to set up differential game models including jointly managed inventory(JMI)and decentralized inventory management(DIM)under the background of continuous time.Nash equilibrium’s existence of constraint equations was proved and corresponding optimal inventory differential strategies were proposed.Finally,by numerical simulation,preservation efforts,inventory changes and total supply chain profits were explored under the two models and corresponding suggestions were given.
