Abstract: 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.
