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...

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.

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.

The share of a railway transportation channel and competition in medium and long distance passenger traffic market were analyzed.A multilevel programming model for pricing of high speed passenger lines with different classes of trains was proposed.In this mode,the requirement of passengers to choose a train based on minimum generalized cost,maximum benefits for transportation enterprises and share of the railway channel by the existing lines were considered as the optimization objectives...

The share of a railway transportation channel and competition in medium and long distance passenger traffic market were analyzed.A multilevel programming model for pricing of high speed passenger lines with different classes of trains was proposed.In this mode,the requirement of passengers to choose a train based on minimum generalized cost,maximum benefits for transportation enterprises and share of the railway channel by the existing lines were considered as the optimization objectives to get the best or the almost best methods of pricing.The model was solved with a genetic algorithm.

分析了中长途旅客运输市场竞争环境以及运输通道内既有线和客运专线合理分工.提出了客运专线多产品票价制定的多层规划模型.模型中不仅考虑了基于广义费用最小的旅客出行选择要求和运输企业效益最大化,并且兼顾了与客运通道内既有线的分工,其优化目标是得到最优或接近最优的票价制定方案.探讨了求解该模型的遗传算法.
