随着经济的发展,易逝品的运输量在不断增加。在时变条件下的运输网络中,易逝品的运输成本和耗损随着时间的变化而有所不同。文章在时变网络条件下,获得易逝品运输的成本和耗损的基础上,研究了易逝品运输的路径选择;给出了有达到时间限制的易逝品运输的路径选择模型;设计了路径选择的算法,并对算法的计算复杂性进行了讨论;最后给出了一个算例。 With economic development, the volume of perishable goods is increasing. In a time-varying transport network, the transport costs and wear of perishable goods vary over time. Based on the time-varying network conditions and the cost and loss of perishable goods transportation, the path selection of perishable goods transportation is studied. The routing model of perishable goods with time limit is given. The path selection algorithm is discussed and the computational complexity of the algorithm is discussed. Finally, an example is given.
