【摘要】 针对第三方物流配送特点的道路网建模,通过系统分析第三方物流配送活动中各因素间的相互影响关系,归纳出道路网建模影响因子,并对道路地理信息全集进行抽取,得到道路网模型的拓扑视图。通过最短路径算法将其转化为最短路径视图,替代传统地理信息系统或组件,来支持配送路线规划。最后,进行了道路网建模应用验证。结果表明,该模型的应用提高了配送规划计算的运算效率和准确性。更多还原

【Abstract】 Aiming at road network modeling oriented to third-party logistics distribution,by systematically analyzing correlations among distribution elements,influencing factors of road network modeling were summarized so as to extract topological view of road network model in road geography information universal set.By shortest-path algorithm,the topological view of road network model was transformed to shortest-path view to replace traditional Geographic Information System(GIS) or components to support distribution route planning.Finally,modeling was applied for verification,and the computation efficiency as well as the accuracy of distribution route planning were improved.更多还原
