Research On The Problem Of Intra-city Express Distribution Center Location-CFLP Model Based

As the the rapid development of China's logistics, e-commerce, Internet and economic output, China's express delivery industry has been developpen rapidily. Many Express Company successively carried out intra-city express in order to find new market.At the beginning of the business, distribution center location is very important. How to select intra-city express distribution center scientificialy and rationaly is a major Problem to be solved for a lot of companies. Therefore,it's of great significance to study of intra-city express distribution center location.The author's research on the intra-city express distribution center location problem is include the following aspects:①The author gave the concept of intra-city express,analysis of the characteristics of intra-city express,and analysis of the status of domestic city express development, and proposed the technical route of research.②Based on the overviewing the theory of the distribution center location ,the author summed up the research results about domestic and international distribution center location problem, and gave the steps of CFLP model based Distribution Center Location .③Based on analysis of the characteristics of intra-city express distribution center , building meaning and operation mode, The author gave the principle of intra-city express distribution center location and site selection procedures, analied of the factors of intra-city express distribution center location and conducted AHP-Gray Comprehensive Assessment to conduct rough distribution centers location.④Based on establishment of intra-city express distribution center location assumptions and model parameters, The author established a CFLP model based intra-city express distribution center location model, and established a Final Distribution Center Path optimization Model. Model 1 take the total transport costs between the distribution center, the transport costs between the distribution center and the customers, infrastructure costs and response delay fees of distribution centers smallest as object. Model 2 take the smallest fees occurred between the process of Vehicles traverse starting from the express company headquarters traversal selected distribution center only once and then returned to the headquarters as object. ⑤The author take Ji-nan lutongyu intra-city express distribution center location problem as an example. according to the established intra-city express distribution center location methods and steps, first, the author Conducted a rough location used gray comprehensive evaluation mehods,then take further screening on distribution centers location and gave the final result. On this basis, by solving the TSP, the author given the optimal path of the vehicle starting from the headquarters of the chosen distribution center traverse only a final return to the headquarters.The conclusion is:the intra- city express distribution center location methods which the author proposed (used of AHP-Gray Comprehensive evaluation method to conduct rough distribution centers location, With the established intra- city express distribution center location model based CFLP model to determine the final location, and optimized the selected distribution centers's path.) can be scientific and reasonable to carry out the distribution centers that used minimum total cost for conducted intra-city express company.
