Abstract: In view of the large number of electronic commerce returns, a kind of integrated distribution mode is put forward, which is based on the third party logistics and self built logistics. Location Routing Problem （LRP） has become a very difficult problem to be solved. In order to reduce distribution costs and improve customer satisfaction, using the improved genetic algorithm, the first time window is added in the self built logistics cost penalty function, remote area distribution is used third party logistics distribution mode, pick up reverse logistics are established as one of the current location of the path model; then aiming at the problem of the complexity, a genetic algorithm is designed to solve the model, the time distribution thought is used for initialization, local search algorithm is introduced, adaptive genetic algorithm is improved; finally, through data analysis for reducing logistics costs, reduce the running time, improving the operating efficiency which verifies the validity of the model feasibility and algorithm.

Key words: reverse logistics, third party distribution, e-commerce, location route
