| 摘 要： | 在给定一个单源单汇物流运输网络中，网络中的每条弧都有一个容量和运输时间的限制，研究了当网络的容量提高到指定水平，同时限制从网络中源点到汇点运输时间，应该如何对网络进行适当的扩张，减少网络的运输时间，同时使网络效益与预期效益尽可能的接近。

| Abstract: | In a given directed logistics transportation network with only one source node and one sink node, every arc has capacity to be improved to a given level and there is time limitation between source node and sink node, how to appropriately expand the network and shorten the transportation time to reduce the difference between network benefit and expected benefit to the largest extend. The model presented here is very practicable, |
