As a bottleneck of electronic commerce,logistics distribution seems more and more obviously restricting the development of electronic commerce.In logistics distribution system,distribution center is becoming the symbol of modern logistics,and effect the expense,efficiency and development of the entire logistics distribution system.Once the place of the distribution center confirms,it will not alter in long time.This means if the place of distribution center is confirmed unreasonably,reselect and build the center will spend such large expenses of regular facilities as the warehouse and so on.And it will take too much if not to reselect the center,that will enable being worthy of sending goods to every site for along time,because of the unnecessary waste.Therefore,whether the location of the distribution center is rational will influence the benefit of the logistic distribution center or even the whole logistic system. This article mainly obtains following some research results: First.In consult related literature foundation,summarized under the traditional distribution and the electronic commerce environment distribution difference and under the electronic commerce environment the logistics distribution presents new characteristic. Second.Through the electronic commerce environment of logistics distribution and traditional logistics and distribution of the contrast analysis, combining the actual situation, established the e-commerce distribution center location model and route optimization model. Third.Has designed the solution algorithm.
