Abstract: To construct the reasonable logistics network in dynamic competitive environment,the customer utility function was proposed by considering the factors of service level,price and distance.The bi-level programming model with the enterprise as the leader and the competitor as the follower was established to optimize sale terminals based on the differences and changes of customer value.The model to optimize enterprise's upstream network was proposed to achieve overall optimization of the enterprise's logistics network.For the characteristics of the model,an iterative solving algrithm was designed based on the fast and elitist non-dominated sorting generic algorithm,and a  simulation example was studied.Analysis results showed that the enterprise obtained good results on the profits and sales,and the proportions were 50.81% and 55.75% respectively,which was better than that of calculated by Lingo 10.0.The validity of proposed model and the algorithm were indicated by the numerical simulation,which provided theoretical support for logistics network design based on the differences of customer value in dynamic environment.
