Research On Multi-layer Multi-logistics Network Distribution

With the steady development of China's economy,e-commerce and information technology has also made great progress,and also to a great extent,promote the development of the logistics industry,i n addition to the express industry,there are also many enterprises began to develop its own logistics system,the logistics industry in our daily life has become more important,enterprises in the investment of logistics is also increasing.Express indust ry and electronic business enterprise to see,their logistics system almost cover various regions and cities in the country,top-down,involve more than one level of logistics node as the basic unit of the logistics system,has a very important role,more the multilayer logistics network is the need of practical problems,to study the layout problems by logistics distribution network research,can save resources,minimize the logistics cost,also can make the transit warehouse coverage and flows through put more reasonable,improve the efficiency of logistics.In this paper,the logistics distribution center location problems and logistics distribution network research generalizes the literatures at home and abroad.At the same time introduces the Su Ning pu rchase logistics present situation,it involves the different levels of multiple regions and cities,is a typical multi-level logistics distribution network problem.In addition,this paper also introduces in detail a yuan logistics network layout model wi th multiple logistics distribution network model,hand in hand the comparative analysis on them.To end multilayer multiple logistics node layout problem,considering the transit warehouse only have single function and compound function of both cases,the corresponding logistics distribution network model is established.According to the established model,the selection Su Ning in Anhui province as an example,model application to Su Ningyi purchasing logistics node layout and optimization in Anhui province.In this paper,we study through the distance between city and through put to determine its logistics cost,logistics cost minimizing target layout research,it is concluded that in a single function and compound function in both cases,Su Ning for Anhui p rovince transit warehouse location selection,scale and its coverage.Based on the research of the multilayer multiple logistics node layout problems and case application,prove that this model and the research process is practical,can be applied to othe r similar layers of multiple logistics node layout problems,for multilayer multiple logistics node layout problems that exist in the reality provides the solution and method,can reduce logistics cost,and can improve the efficiency of logistics.
