摘要
以粮食物流企业的配送问题为背景,结合GIS理论和方法,对粮食物流配送决策支持系统进行了系统分析。首先结合粮食物流配送决策支持系统的数据需求,详细分析了数据库系统的结构;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了设计。建立了基于GIS的粮食物流配送系统模型,为GIS应用于粮食物流配送决策支持系统(GLD_DSS)提供了较实用的指导性方案。
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.
