本科论文AbstractDistribution is an important link in the whole logistics system, If the distribution path selection With the rapid development of social economy, logistics plays an important role in economic activities, which attracts the attention of all walks of life. is unreasonable, it directly leads to inefficient distribution. The algorithm can be used to plan a satisfactory solution that meets customer conditions and works efficiently which can significantly reduce logistics costs can increase the profits of enterprises and market competitiveness. First of all, by consulting the relevant literature to understand the current situation and existing problems of cold chain distribution, this paper expounds the related theories of cold chain logistics and distribution, distribution center, and related VRP,and analyzes the problems existing in the distribution link of J company, collects and studies the distribution data of J company, converts inge-latitude-to-realistic plane coordinates and then calculate them, then uses the saving odometer method to solve the distribution model of J company. Secondly, through the comparison of distance, cost and load rate before and after optimization, it is proved that the algorithm is effective in solving the distribution route problem of J Company. Finally, the mileage saving algorithm is realized by using MATLAB. The results show that by using the mileage saving method to plan the vehicle path of company J, the investment of vehicles and personnel can be reduced, the driving distance can be shortened, and the customer can be provided with faster delivery service. The design of this paper is based on practical problems, and the results show that the algorithm has stron...
