摘要: 大规模的军用物资调度,需要传输的物资远远超出保障网络实际传输能力的情况下,现有的Dijkstra算法、Floyd算法以及传统的网络K-最短路径算法,难以求解这类网络调度优化问题。在蚁群算法的基础上,设计了一种基于时间扩展的网络K-最短路径算法,满足网络传输一致性假设的前提下,求解大规模定量传输问题。最后给出面向任务的物流保障网络调度的应用实例,获得满意的网络调度优化方案。

Abstract: The mass multi-commodity network scheduling problems can not be solved by the Dijkstra,the Floyd and the other the conventional static algorithms under over-loading transportation.Based on the Hypotheses of the temporal consistency of transportation,this paper presents a time-expanded network K shortest paths algorithm(TEN-KSP).In the last,a application case on the logistics support network scheduling problems is studied by this algorithm,and satisfied optimal solutions are gained.
