Research on Contract Logistics Mathematical Model and System Based on Undo and Baidu Map

摘要

Based on fleet size and mix vehicle routing problem (FSMVRP), the article analyzes the contract logistics transport demand and characteristics. The authors establish a fleet combination and route optimization model with multiple transfer centers and multiple transport methods. Furthermore, according to the webgis service of Baidu Map, the authors develop a corresponding logistics system according with J2EE framework. Finally, Lindo solver figure out the minimum cost and solution for the dedicated situation, and results display in the Baidu Map.
