Analysis and design of grain logistics decision support system based on GIS
基于GIS的粮食配送决策支持系统分析与设计

Based on the grain logistics distribution problem of the grain logistics enterprise, combing with the theory and methods of GIS, this paper did the systems analysis of the GLD_DSS (grain logistics distribution_decision support system). Firstly, analyzed the structure of the database system of GLD_DSS according to the data demand of it. Then, discussed the model base of the LD_DSS, discussed the flow of some core problems such as grain distribution centers allocation and the transportation routes planning in the grain logistics distribution system. Constructed a grain logistics distribution system module based on GIS, which provided a practically instructional scheme for applying GIS to the grain logistics system.
