摘要
建立了基于多种运输方式的第四方物流路径优化模型,通过虚拟运输网络,将第四方物流路径问题转化为一个带时间约束和能力约束的最短路径问题,并给出了基于Dijkstra的启发式算法。算例显示,该算法能方便有效地求解基于多种运输方式的第四方物流路径问题。
The paper estabhshes a route optimization model for fourth party logistics （FPL） based on multi-modal transportation which, through virtual transport network, converts the route problem of FPL to a shortest route problem with time and capacity con- stralnts, and gives a Dijkstra-basod heuristic algorithm. A subsequent numerical example shows such algorithm can easily and efficiently solve the route problems of FPL with muhi-modal transportation.
