Research On Optimization Of Cold Chain Distribution Path Of Agricultural Products Of Auchan Chain Supermarket Based On Low Carbon

With the rapid development of China's economy and the improvement of people's consumption level,people's demand for fresh agricultural products is increasing,which makes China's cold chain logistics enter a stage of rapid development.However,as an important branch of the logistics industry,the characteristics of high energy consumption and high carbon emissions of cold chain logistics are contrary to the “low carbon economy” advocated by China.Therefore,considering the low-carbon agricultural product cold chain logistics distribution path optimization problem is an important research content.This paper is based on the existing research results on low carbon logistics,cold chain logistics and vehicle routing at home and abroad,focusing on the optimization of the cold chain distribution route of agricultural products in Auchan supermarket chain.Firstly,the related theories related to the low-carbon agricultural product cold chain logistics distribution problem are expounded.Secondly,it analyzes the current situation of cold chain logistics and distribution of agricultural products in Auchan supermarket chain,and solves the problem of unreasonable planning of agricultural product distribution route in Auchan supermarket chain,combined with low carbon concept,with the goal of minimum distribution cost,the rated load of refrigerated trucks,stores.As a constraint condition,the specified time window and the demand of the store are used to establish a cold chain distribution route optimization model based on the low-carbon single-vehicle field with soft time window constraints.Thirdly,the genetic algorithm is used to solve the design of the model.Finally,using MATLAB software to analyze and solve the data of agricultural distribution routes of Auchan supermarket chain,compare and analyze the optimal path obtained by considering low carbon and not considering low carbon,and from Auchan supermarket chain and government Relevant suggestions were put forward.By comparing and analyzing the results of considering low carbon and not considering low carbon,it is concluded that although the former travel distance has increased by 5%,the carbon emissions have decreased by 17.7%,and the total distribution cost has decreased by 4%.Through the research work in this paper,the carbon emissions and energy consumption in the cold chain distribution process of agricultural products in Auchan supermarkets were finally improved,which reduced the distribution cost of agricultural products in Auchan supermarkets to a certain extent,making the distributionroute of agricultural products more environmentally friendly and economical.At the same time,the research results of this paper also have certain reference for enterprises in the same industry.
