摘　　要：依据区域性铁路网成网条件建立以运输成本最小、运输时间成本最小、运输效率最高、货主期望的货物安全成本最小为目标函数的多目标货流分配规划模型,利用主成分分析法对模型求最优解,得到货流径路优先权的选择,最终确定货流在路网上的最佳分配。它是缓解铁路运输紧张状况,最大限度地扩大运输能力最有效、最现实的方法,也是转变铁路经济增长方式,提高经济增长质量的必由之路。A multi-objective goods flow distribution planning model with the goals of minimum transport cost, minimum transport time cost, owner desired maximum transport efficiency, minimum freight security cost was established under the condition of regional railway network. Using the principal component analysis model to get an optimal solution ,then, the given priority to freight flow pathway choice was obtained. Finally, the best allocation of the freight flows on the railway network was determined .This is the most effective and realistic way to alleviate the tensional railway transport situation and to enlarge the transport capability to a large extent, and is also a prerequisite for transforming railway economy increasing mode and improving economy increasing quality.
