摘要
结合粮食物流配送系统的数据需求,详细地分析了粮食物流数据库系统的结构;然后根据粮食物流配送的决策问题,研究分析了粮食物流配送决策支持系统中配送中心选址优化以及粮食配送过程中车辆路线规划等核心模块,并对模型库系统中的模型进行设计。建立了基于GIS的粮食物流配送系统模型,并在实际中得到应用。
Firstly, the structure of the database system of GLD_DSS is analyzed according to the data demand of it. Then, the model base of the LDDSS is discussed, the flow of some core problems such as grain distribution centers allocation and the transportation routes planning in the grain logistics distribution system is discussed. A grain logistics distribution system module based on GIS is constructed in this paper, which provides a practically instructional scheme for applying GIS to the grain logistics system.
