Research On Location Of Terminal Distribution Network Of S Express Company Based On Immune Algorithm

Express terminal logistics is a logistics service provider will express packages from the last distribution network directly to consumers,to meet the logistics link terminal customers for the purpose of logistics activities.At present,the most common way is to Courier express parcel delivery from city distribution center and then direct door-to-door delivery to the customer.In recent years,with the increase the amount of delivery,delivery and receiving the contradiction between gradually revealed,such as often lead to express for residents to work,students can't directly to the hands of customers;Community unit for security management demands,limiting Courier out casually,a Courier delivered tend to run several times to often occurs,so that to a large extent affected the terminal logistics distribution efficiency and customer satisfaction.To alleviate terminal logistics difficult problem,this paper puts forward between the city distribution center and customer set up at the end of the end of the distribution network distribution way,that is,from urban distribution network to the customer at the end of the distribution center to distribution way,express delivery at the end node as a connection hub station express enterprise distribution center and consumers,from point to surface covering the entire community,office buildings,schools,such as distribution terminal,customers are free to choose express packages way and time,reduce the handover package costs,make more flexible trading time.Distribution network in the end of the above in all aspects of the site selection is related to the rationalization of distribution system and the social benefit of commercial circulation major investment decision making problems,this paper will focus on research express enterprise terminal distribution outlets location layout problems.This article first chapter elaborated our country express Courier package quantity in making enterprise terminal distribution link disorderly want to,to understand the logistics distribution at the end of the express industry development at home and abroad and the research status quo,and put forward the express companies to establish distribution points at the end of the purpose and meaning.The second chapter is overview of terminal location method theory of logistics and logistics,analyzes the principle of distribution network location at the end of the Courier companies,consider the factors and the location of the program,and the logistics location method,comparison,summarized and analyzed.Laid a theoretical basis for distribution network location can be found below.The third chapter is to express enterprise terminal distribution outlets location layout problem is established considering the location model of distribution quantity and distance and their thinking and steps of the immune algorithm is introduced.The fourth chapter to express company S site development present situation as the research background,analyzes the distribution network location at the end of the external and internal environment,master S inadequate distribution status at the end of the express company,combining with the development trend of terminal distribution,proposed at the end of distribution network.Through the Courier company S main distribution present situation research,under the condition of considering artificial cost and construction cost to build the building before and after the distribution network S Courier company at the end of the benefit model,from quantitative Angle determines the number of distribution outlets at the end of the scale is established.Then,according to the above site selection of the construction of a model,application of immune algorithm ideas in the Matlab environment for location results are obtained.The fifth chapter mainly express company S terminal distribution outlets location after operation,from the talent employment,the construction of information system and the differential distribution way three aspects.The sixth chapter is conclusion and prospect.Above research is of guiding value to company S terminal distribution outlets location,and also to express enterprise logistics distribution at the end of the research has reference significance.
