摘要
介绍了运输界关于车流径路的研究成果；分析了已有车流径路模型在车流已知情况下只对重车流径路进行优化所存在的不足；运用系统论及网络理论，对路网上双向、空重车流进行路径优化，构造了具有中国铁路网特点的适合于市场经济的多目标模型。
On the basis of analyzing the previous papers published home and abroad, and considering the special characteristics of Chinese railways and “Socialist market economy”, the paper presents a multi-objective decision model of train flow with two directions, heavy and empty cars in a railway network, in which there are five objectives, twelve system constraints and two nonnegative constraints.
