| 摘 要： | 为了充分发挥铁路通道的整体运输能力,基于铁路运输通道分工影响因素的分析,建立了以通过能力为约束条件,以运输成本、旅行速度和日常运输组织调整为优化目标的客运专线建成后与既有线形成的铁路运输通道分工优化模型.运用满意优化理论,对构建的模型进行了改进,将多目标优化问题转化为单目标优化问题,并给出了改进模型的求解步骤.研究为铁路运输通道内平行线路的合理分工提供了理论参考.

| Abstract: | To sufficiently give play to the transportation capability of railway transportation channels consisting of a dedicated passenger line and an existing line,factors influencing the share of railway transportation channels were analyzed,and a mathematical model of railway transportation channel share was set up.In this model,the optimal object is transportation cost,traveling speed and routine transportation regulation,and the restriction condition is carrying capacity.In addition,this model was improved by using the satisfaction optimization,the multi-objective optimization was transformed into a single objective optimization problem,and the corresponding algorithm was given.The research provides a theoretical reference for the share of railway transportation channels. |
