Study on Location-Selection of Logistics Distribution Center Based on GIS and Weighted Steiner Tree

Choosing a location in a scientific and effective way is a precondition for development of E-commerce´s distribution center. With the development of computer science and information science, Geographic Information System (GIS), relying on its versatile tools in spatial analysis and visualization, makes Location-selection of distribution center more precise and more perceptible. In allusion to the traditional location model based on the algorithm encapsuled by GIS software and Steiner tree problem, this paper proposed a location model of Weighted Steiner tree problem and gave its improved algorithm based on Multi-Agent System. Then the combination of programming tools and GIS software has analyzed and carried out location problem for distribution center in E-commerce environment based on this model, and some tests have been made to prove the feasibility of this model.
