Optimization Of Cold Chain Logistics Transportation Path Of Fresh Agricultural Products

With the improvement of the quality of life of the people in China's economy,people's requirements for fresh logistics products are also increasing.Therefore,the development of cold chain logistics technology has brought opportunities and challenges to the cold chain logistics and distribution industryThis paper summarizes the research on the related research of cold chain logistics,vehicle routing problem and fresh agricultural products by domestic and foreign scholars and experts,and analyzes the development status of these three aspects.In the research,it is found that the production and demand of fresh agricultural products in China are large.However,China's fresh agricultural products have low cold chain transportation rate,low transportation efficiency,and large cargo loss rate during transportation.This paper uses fresh agricultural products as the research object,analyzes the related characteristics and influencing factors of cold chain logistics and vehicle routing,obtains relevant theoretical basis,and studies the optimization of cold chain logistics transportation path of fresh agricultural products demanded by urban residential quarters.Firstly,the theoretical basis of the characteristics of fresh agricultural products,the concept of cold chain logistics,and the problem of vehicle routing are summarized.The problem of cold chain logistics transportation path of fresh agricultural products is described.Considering the cost factors of each link in the cold chain distribution process,after analyzing the multiple costs in the cold chain logistics transportation process of fresh agricultural products,the total cost is optimal.The objective function establishes a mathematical model.After the model was established,the supermarkets near the 10 residential quarters in Zhengzhou City were randomly selected as the distribution points,and the third-party cold chain logistics distribution center transported the fresh agricultural products in a large farmer's market in Zhengzhou.Then data collection and collation,using genetic algorithm and MATLAB 2015 b to solve the case to obtain the results and the optimal transportation path,analyze the number of each cost of the experimental results and the proportion of the total cost,and propose corresponding solutions.Then,the transportation method based on the regional location distribution is used to solve the problem,and the results of the two experiments are compared and analyzed to obtain the optimal transportation path and minimum transportation cost.
