The Logistics Dispatch System

Recent years, logistics, taken as "third profit resource ", has been developing rapidly. Lots of physical distribution centers were established to improve the efficiency of goods flow by large factories and commercial firms. Meanwhile, considerable sum of transportation corporations, storage enterprises and shipping companies are taking on business of third party logistics, The distribution business is now flourishing, How to decrease distribution cost is concerned..Elaboration on the knowledge of physical distribution, this paper attempts to take delivery routing and inventory as the core problem - VRP for further research.On the vehicle assigning problem of VRP, analyze this problem in the logistics at first .Second , in term of the restrains and objective , the general mathematics model of this question is introduced, Set up vehicle data base and use a kind of new-type algorithms which is high accuracy , operation is fast to solve the problem .On the vehicle routing problem of VRP, first, analyze this problem and mathematics model is introduced. Set up geographical data base in order to store the area's geographical information The geographical data base can reduce the time of making the logistics plan greatly .On the basis of geographical data base, delivery goods directly can find the routing of providing and deliver in the geographical data base directly, For delivers goods for the demand most with the vehicle at least and delivers goods with time restriction problems, optimize the routing with a kind of algorithms of intelligence -ant algorithms.Because of the prosperous future of logistics development, the logistics dispatch system will be of great necessity. Base on practically and flexibility, primary design of the system is worked out in this paper.
