线路通过能力限制下的变参数空车调配模型研究
Study on the empty cars distribution model with variable cost parameter and line carrying capacity
以空车总走行里程最小为目标,以空车供需平衡和径路通过能力为约束条件,并考虑径路可以多选择情况下变化的走行费用成本参数,建立空车调配数学模型,并使用Lingo进行求解。在实际应用中,路网配流相对均衡,有效地利用了路网通过能力。结果验证了模型的可行性和正确性,同时相对于分步优化迭代算法,模型求解更为高效。
ombined with the restrictive conditions of cars supply-demand equilibrium and line carrying capacity, and the variable cost parameter for each empty car flow delivering with multi route selection, the programming model for distribution of empty cars is established aiming at the minimization of consuming car-kilometer, which is solved by LINGO. In practice, the more balance car-flow distributed on the lines, the more effective utilize of every line carrying capacity. Applied result has testified the feasibility and validity and high efficient of railway network empty cars distribution model.
