A New Collaboration Distribution Network Base on Third Party Logistics Alliance

摘要

This paper researching on vehicle collaboration distribution of TPL alliance, discussing the solution to the arrangement of vehicle routing problem which is base on "multi-deport" vehicle distribution of the triangle network. As for the key situation of vehicle distribution, clusters the supply and demand nodes into sliced area in order to constrain triangle distribution model and realize the triangle closed-loop route of vehicle distribution in both pickup and delivering. By comparing relative advantages of the traditional distribution model and the triangle distribution model on many code aspects; then stimulate the problem with improved ant-algorithm; finally analyzes the results of stimulation. The results imply that the triangle network of vehicle distribution can reduce unload ratio and the cost of transportation, can improve full-load ratio and can achieve the optimal allocation of transport resources.
