Research On Location Selection And Distribution Route Optimization Of YXY Chain Supermarket Distribution Center

With the improvement of residents’ consumption level,the rapid development of many small and medium-sized supermarkets for the supermarket chain,and a growing number of stores in order to ensure the quality of service and comply with its own development trend,establish distribution center to become one of the effective methods to improve their service level,and the rationality of the distribution center location,distribution center is the precondition of effective operation,only the correct location to ensure delivery Long term use after completion of the center This paper choose YXY supermarket chain as the research object,on the study of distribution center location and distribution route optimization problem,through the study of the comprehensive evaluation of three possible choose a better place,because the location selection stage only consider alternative points of open loop route,in order to improve the distribution efficiency and reduce pollution to the environment,determine the location of point to point again after closed-loop optimal route With the newly built distribution center as the origin,the distribution route is designed based on the actual distribution of all chain stores in the urban road network,laying a foundation for the long-term development of YXY supermarket chain.The main research contents are as follows:The first chapter introduces the research background and significance of this paper.The research status of distribution center location and distribution path optimization at home and abroad.The second chapter introduces the related concepts and methods of supermarket chain distribution center location The third chapter mainly introduces the current development status and existing problems of YXY supermarket chain.On this basis,the iterative center of gravity method is used to roughly select three alternative points,which can not only narrow the range of site selection,but also provide data basis for comprehensive evaluation and path optimization in the following paper Fourth alternative points of evaluation and the path optimization model,using literature analysis method to determine the three alternative points first evaluation index,build 29 by seven indicators and secondary indicators of evaluation system,using the subjective level analysis and in combination with the objective entropy weight method to calculate indexes weight,and then use TOPSIS method from the aspects of twenty-nine to comprehensive analysis of three alternative points,choose the match Send center position,the best construction in the new distribution center as the origin,using the save mileage method path for closed-loop optimization of distribution centers,and the optimized results compared with open loop distribution way,the optimized distribution distance decreased by 123.2 km,distribution route to reduce the article 12,the day the shipping cost reduced336.1 yuan,distribution vehicle utilization 31.39%,and achieved better optimization results.
