Research On Cost Optimization Of Agricultural-supermarket Docking And Distribution Based On Agricultural Product Cold Chain Logistics

With the continuous development of economy,the problems in China's agricultural development have gradually emerged,among which the circulation of fresh agricultural products has become the bottleneck of China's agricultural development.Fresh agricultural products have the characteristics of perishable and short shelf life,and there are problems such as large loss and high preservation cost in the circulation process.Therefore,China puts forward the operation mode of "agriculture-super connection".In addition to the mode of farmers and middlemen to reduce the circulation of fresh agricultural products,but there are still a lot of waste in the shipping,so how to reduce the fresh agricultural products in the process of cold chain distribution costs,improve the efficiency of distribution,ensure freshness levels are farmers and pattern of fresh agricultural products to solve the problem.Based on farmers and fresh agricultural products distribution system as the research object,aiming at reducing distribution costs,introducing fresh cost coefficient,with fresh cost path optimization decision model is set up,and use genetic algorithm to solve the path optimization problem with time Windows,and then solve under the model of the actual application of X company.The specific research contents are as follows:firstly,starting from the characteristics of fresh agricultural products,the research status at home and abroad is reviewed,and the basic knowledge related to agro-supermarket docking,fresh agricultural products cold chain logistics,vehicle path with time window and genetic algorithm is sorted out;Second,discusses the farmers and distribution modes at present stage,the farmers and points out the fresh agricultural products cold chain logistics distribution mode existing problems,and thus introduce fresh cost coefficient,through the study of the change of container transport vehicles,not the stratosphere method are adopted to decrease the cost of keeping fresh,and set up including preservation of the cost of the cold chain logistics under the path of the farmers and optimized decision-making model,Through the comparison of different algorithms,this paper selected the genetic algorithm as the model solution algorithm,and combined with the characteristics of rural super docking,the genetic algorithm was designed;Finally,the existing distribution route of X Company is optimized through the analysis of the calculation examples,and compared with the original route,it is concluded that the optimized distribution route can reduce the cost and increase the profit,which further proves the feasibility of the model and algorithm and has good application value.
