摘　　要：研究了城市物流配送信息查询系统。根据城市交通网络的特点,运用结点-弧段-有向线结构描述交通网络,利用动态分段技术建立了基于MapInfo的配货网络数据库。充分考虑了配货路线短、用时少、费用低的特点,提出了一种物流配送最优路径算法。采用Delphi和MapInfo集成开发方式,设计了城市物流配送信息查询系统,实现了输入查询信息或直接对地图操作来获得配货最优路线,提高了城市物流配送的便利性和高效性。The city logistics distribution information query system is studied. According to the characteristics of city traffic network, the traffic network is described by making use of the structure of node, arc and directed line segment. Spatial database of logistics distribution traffic network which based on MapInfo is proposed by using dynamic segmentation. In view of the characteristics of logistics distribution such as the shortest route, the minimum time and the lowest expenditure, an optimal route algorithm of logistics distribution is presented. The city logistics distribution information query system is designed by adopting the integrated development mode of Delphi and MapInfo. By entering the query information or operating the digital map directly, the user could acquire optimal route of logistics distribution. The conveniency and efficiency of city logistics distribution could be improved by using this system.
