| The rapid development of e-commerce had brought huge impact to logistic distribution in recent years,which pushes distribution to develop as well as exposed lots of problems,including the disorder of distribution network,unreasonable of vehicle routing arrangement,the low degree of scale distribution.In order to optimize the urban logistics node layout and broke through the limitation of the traditional logistics distribution.Three-echelon distribution mode based on joint distribution had been put forward in the thesis under the research of e-commerce and chosen the public distribution center location as the main line,and objected of WuChang district in Wuhan city to study distribution network planning.The domestic and foreign research achievements about e-commerce and theoretical knowledge of city logistic distribution location had first been reviewed.Second,the influence factors of express delivery business based on the theory of consumer behavior had been explored.The mathematical statistical analysis software SPSS was used to analyze correlation and multiple regression analysis between influence factors and express delivery business.Third,in the background of many problems of the traditional logistics distribution,Three-level distribution mode based on joint distribution had been put forward and analyzed the distribution process and each node location principle.Fourth,WuChang district of Wuhan city had been chosen to research the public distribution center location as a case,primary branches express enterprise distribution center address had been determined via the Internet;Then,the end joint distribution outlets had been determined by using the theory of center of hexagonal network location;Third,three proposed public distribution center had been chosen by set covering model;At the end,the location had been determined based on the limit of the 0-1 mixed integer programming model.A reasonable distribution center location had been chosen by using this method. |
