Optimization On Distribution Route Of XX Fast Food Company Of Shunyi Beijing

With the development and innovation of logistics industry, distribution industry tends to be a way with small-volume and multi-batch which has led many businesses face greater challenges in logistics costs.In recent years, the Vehicle Routing Problem (VRP) becomes an important topic in the study of the logistics management. Choosing the rational planning Vehicle path can improve the ability of handling emergency events, the level of customer service and satisfaction, reduce logistics costs, and enhance the overall efficiency and economic level.Therefore effectively selecting the logistics route and scheduling delivery vehicles have become an important way to control distribution costs. There are many methods to solve the problem of the distribution path, such as C-W algorithm, nearest neighbor scanning method and genetic algorithm. C-W algorithm is the most widely used as a vehicle routing optimization algorithm. It has significant advantages in speed and ease of implementation.The paper uses documentary research, qualitative analysis, field investigation and factor analysis, based on a large number of academic literatures. In addition it also integrates the theory of logistics and supply chain management and combines the operating overview of xx Company. Accordingly, the paper wants to find a proposal which can optimize the distribution routeThe paper proposes some current researches and methods of vehicle routing problem and introduces the basic principles, the basic provisions of the advantages and disadvantages as well as the calculation step detail of C-W algorithm.Combining the distribution status of XX Company, obtain the shortest distance between the distribution center to each network and the shortest distance among each network which can calculate the saving path between the various distribution points. Then the saving mileage and get the final optimized distribution route can be use. However, this method has limitations of which it can only consider the impact of the geographic distance.Therefore, this paper attempt to improve the optimization of savings path algorithm, depending on operating status, delivery status and influencing factors in the distribution process of the actual transportation. Through factor analysis, build a set of index system, which can get the weight of each factor to find out that which one need to consider firstly. This method can reflect the economic factor, time factor and distribution management factor in optimizing the distribution route.Finally, the paper compares the results between the pre-and post-distribution route, verifies the feasibility and operability of the improved method, at last gets the resulting distribution route optimization program of the XX Company, which can use the improved algorithm to enhance the economic efficiency and the delivery service level of enterprises.
