Research On Terminal Facility Location Of Fresh Agricultural Products’ Joint Distribution Under E-commerce Market

As people’s living standards improve, consumers demand for fresh produce growing,the demand for its freshness is also growing.At the same time, as e-commerce go into people’s daily lives, online shopping has become a trend, the proportion of fresh agricultural products in online shopping is growing.The biggest difference between fresh products and ordinary consumer goods is the perishable characteristics.It makes the study of fresh produce and other studies are essentially different.Firstly,this thesis analyzes the nature of fresh products and logistics status,and compares the joint distribution under E-commerce and traditional supermarket distribution,then points out the advantages of joint distribution and set up mathematical model in the base of joint distribution.Secondly,using the the bi-level programming as a modeling tool,standing on the perspectives of logistics planners and consumers respectively,the thesis establishes the upper and lower mathematical model.From the point of view of logistics planners,it establishes the minimum cost upper model.From the customer’s point of view, it sets up the maximum customer satisfaction level lower model.In the upper model,the thesis quantifies the costs in the process of the joint distribution,and regarding the fresh degree as the main punishment standard.In the lower model,considering customer satisfaction with distance of the terminal facility as the main research factors.Then combining the two layer problems to form a bi-level programming model for the terminal facility location problem.Then using the heuristic algorithm to solve the model and obtains the optimal terminal facility location. At last, the thesis do a sensitivity analysis of the products’ corruption rate to certificate the science of this model.
