Research On Location Of Cold Chain Logistics Distribution Center Based On Multi-objective

The cold chain logistics distribution center is the hub of connecting the upstream supplier of cold chain logistics and the downstream consumer in cold chain logistics system.How to choose the cold-chain logistics distribution center rationally can improve the competitiveness of the enterprise,which is an urgent problem to be solved.In this paper,the problem of cold chain logistics and site selection was firstly sorted out in the study of the location of cold chain logistics distribution center.Secondly,based on the literature analysis,the influence factors of the site selection of cold chain logistics distribution center are analyzed in detail.Thirdly,based on the factors of environmental factors and customer satisfaction,the siting model of cold chain logistics distribution center was established,and the model was solved by the improved genetic algorithm.Finally,the validity of the model is verified by empirical evidence,which provides a realistic and feasible method for the site selection of cold chain logistics facilities.The main conclusions are as follows:A mathematical model for location selection of cold chain logistics distribution centers is established.Considering customer factors and customer satisfaction and carbon emissions,a multi-objective location model of cold chain logistics distribution centers is established.Based on the actual cases,the paper compares the different results considering carbon emissions and customer satisfaction and not considering the basis of solving the model,so as to provide a reasonable reference plan for the location of cold chain logistics distribution centers.
