Research And Application Of The Location And Path Problem Of Fresh Food Cold Chain Logistics Front Warehouse

With the improvement of the consumption level of Chinese residents and the development of e-commerce,the consumption of fresh products in my country has increased year by year.At the same time,consumers have put forward higher requirements for the quality and delivery speed of fresh products.However,the development of cold chain logistics in China is relatively backward.Fresh food ecommerce platforms still have problems in the distribution of fresh products,such as high distribution costs,distant distribution terminals from customers,large product losses,and high after-sales complaints.The product cold chain logistics front storehouse rationally selects the location and further plans the distribution path to effectively improve the operating efficiency of fresh cold chain logistics,reduce the loss of fresh products,and reduce the after-sales complaint rate,thereby reducing the overall operating cost of cold chain logistics.Promote the healthy development of cold chain logistics.This article first discusses the domestic and international status of fresh product cold chain logistics and logistics node location-path planning,summarizes the development status of fresh product cold chain logistics,and sorts out related cold chain logistics,front warehouse and site selection path optimization The related theory of the problem,then analyzes the current cold chain logistics operation mode of China's fresh products,and at the same time compares the front warehouse distribution mode with the existing distribution mode.Then,according to the characteristics and existing problems of the cold chain logistics operation mode of China's fresh products,the goal of the location and path optimization of the front-end warehouse of China's fresh product cold-chain logistics was designed,and then the solution to the problem of the location and path of the front warehouse was constructed.Mathematical model,combined with the actual situation,design a hybrid algorithm of difference and variable neighborhood descent search to solve the model.Finally,based on the research background of Fresh Food E-commerce Company A in BJ City,through the specific cases involving the location selection and distribution path optimization of the front warehouse,the best location plan and distribution path are obtained,and the feasibility of the model and algorithm is also verified.It shows that the method proposed in this paper can help fresh e-commerce enterprises to expand user groups,increase user stickiness,and effectively reduce cold chain logistics operating costs.
