Analyzing The Patterns Of SCM Based On GIS Technology

The development of supply chain management has played an important role in the development of social economy. The modern logistics enterprises compete with rivals, not only depending on their own capacity, but also by the means of promoting the ally with all jobbers, manufacturers and providers in the supply chain. Their success is based on the efficient cooperation with all logistics nodes in the supply chain. Information technology (i.e. IT) has been recognized as a significant tool that could be used to manage the supply chain effectively and be applied comprehensively. And It is a rising research task for the application of the supply chain management Integrated GIS technology and be paid close attention day by day.This paper is trying to lead the technology and concept of GIS to the major of logistics, in order to constitute a bran-new SCM GIS system.To begin with, this paper introduces the fundamental thesis of SC, SCM and GIS. Next, it analyzes the SCM(supply chain system) GIS system and investigates the total construction, database and designing problems of electronic map in the new system. Furthermore, On the delivery routing problem of physical distribution, this paper firstly puts forward a VRPTW model considering routing and time, which can be solved with the C-W Saving Heuristic Algorithm. Secondly we design concrete steps that how to combine vehicle route optimize model with GIS on the platform of Arc/Info in detail. Then we design the program of C-W Saving Heuristic Algorithm and simulate the VRP problem by giving an example. Finally, the final chapters of this paper make the elementary development and designing of the new system, on the purpose of planning the route of logistics distribution vehicles.From the idea of systematic designing, this dissertation brings forward the method of designing the whole SCM GIS system, concludes the features of the new system and illuminates the problems which should be paid attention to when designing. In the exploitation of example, this paper contrives the configuration and functions of the system and studies the programming to realize it...
