摘　　要：为了解决时变需求下时滞易变质品供应链的协调问题,考虑需求依赖销售价格和变质时间的情形,建立第三方物流服务商参与的三级时滞易变质品供应链协调模型,分别得到分散决策与集中决策下的均衡解。研究表明,集中决策下的时滞易变质品供应链预期利润高于分散决策,且两种决策模式下的预期利润差值随着生产商承担运输服务费用比例的增大而增加。借助常相对风险规避型效用函数与Nash讨价还价理论设计收益共享机制,合理分配集中决策下的预期利润增量。通过数值算例演示了决策变量的求解过程,并通过敏感性分析给出了时滞易变质品特性参数变动对模型结果的影响方式。To solve the supply chain coordination for non-instantaneous deteriorating under time-varying demand, the situation of demand dependent on sales price and deterioration time was considered to establish a three-echelon supply chain model with Third Party Logistics(3PL) participation for non-instantneous deteriorating items, and the equilibrium solutions of decentralized decision and centralized decision were obtained respectively. The results showed that the expected profit of the non-instantneous deteriorating items supply chain under centralized decision was higher than that of decentralized decision, and the difference of expected profit between the two decision modes increased with the increase of the proportion of producer s transportation services cost. With the help of the utility function of constant relative risk aversion and Nash s bargaining theory, a revenue sharing mechanism was designed, and the expected profit increment under centralized decision was allocated reasonably. A numerical example was given to demonstrate the process of solving the decision variables, and the sensitivity analysis showed the influence of the characteristic parameters variation on the model results.
