Logistics Company Vehicle Routing Optimization Algorithm

Following the fast development of market economy, the logistics allocation is more and more brought to people's attention. The development of "The third profit source of profit " also indirectly reflects the development of the entire national economy. Modern logistics is a process that based on customer needs, use the most economic cost and bring the supplies from supply to the demand. It is made up of transportation, storage, processing, packaging, handling, distribution and information activities. Of six ministries (State Economic and Trade Commission, Ministry of Railways, Ministry of Communications, Ministry of Information Industry, Ministry of Foreign Trade, Civil Aviation Administration) in March 2001 in the "speed up the development of a number of observations of logistics," the definition of modern logistics is given in the case Statement: "The raw materials, finished goods from point of origin to destination and related the whole process of effective information flow. It combine transport, storage, handling, processing, finishing, distribution, information, to form a complete supply chain, to provide users with multi-functional, integrated and comprehensive services." The level of a country's logistics development is measured by the international community generally logistics costs to GDP, the lower the proportion of the more advanced.So, how to reduce the logistics costs and improve efficient as top priority the development of logistics industry. This is not only to some of the logistics and express company research background, find out the urgent need to solve the Vehicle Routing Problem, the establishment of a typical model as target genetic algorithms were elaborated with the tabu search algorithm to solve this problem in the advantages and disadvantages, and the proposed genetic algorithm and tabu search algorithm combining a novel combination of algorithms as accurate as possible, to quickly solve this problem, for the vehicle routing problem solving to explore a new method to improve the domestic logistics express core competitiveness of enterprises.
