摘要
以地理信息系统(GIS)为开发平台,以区域电子地图为基础对基于GIS的粮食物流决策支持系统进行了总体结构设计和功能设计,建立了数据库和模型库,实现了订单管理、库存管理、客户管理、车辆管理和模型库管理。通过实证研究,构建了粮食物流中心配送车辆路径优化问题的有时间限制的VRP问题模型,研究了车辆路径优化问题,实现了最优路径的可视化。
Taking the geographic information system（GIS） as development platform,on the basis of the regional electronic map, the overall structure and functions of a grain logistics decision-making support system（GLDSS） based on GIS were designed. A database and model-based management system were developed. The core functions of the GLDSS, including the management of the order, the inventory, the customer relation,the vehicle manenver and the model base were realized. Through the case study, a VRP model with time limitation was established to optimize the routes from the grain logistics center to the end users. The vehicle route optimization problem was studied, and the visualization of the optimized routes was accomplished.
