基于节点重要度的客运专线旅客列车开行方案

将节点重要度的概念应用于列车开行方案的计划制定,通过节点重要度评价指标的计算,建立了客运专线沿线城市的节点重要度三级层次结构,在此基础上提出将一级节点作为列车始发终到起迄点、二级节点采取不固定间隔式停站、三级节点采取低等级列车＂站站停＂的服务方式建立了列车开行方案的多目标数学规划模型,利用lingo编程求解,实现了列车开行方案的停站优化算法.结合武广客运专线的本线列车开行方案制定,对本算法进行了验证.

Train Service Planning for Passenger Dedicated Railway Line Based on Analyzing Importance of Nodes

Starting from the analysis of the economic and social attributes as well as railway resource allocation of the passenger dedicated line（PDL）covered nodes,this thesis introduces the concept of the importance of nodes.On the basis of analytical hierarchy process,the thesis studies the quantitative index of the nodes transport distribution capacity in the PDL network and calculates the evaluation indexes on the importance of those city nodes.Thus,in the light of the assessment results,the thesis sets up the three-level hierarchy in the importance of city nodes covered by the PDL.Based on that,the thesis proposes that the first-level nodes serving as the departure and arrival stations,the second-level nodes adopting the fluid and alternate stop stations,and the tertiary-level nodes takeing the form of ＂all-stop＂ for low-class trains so as to build a multi-objective programming model for the PDL train line planning.With the lingo 8.0 program,the train line planning optimizes the calculation of stop stations.This method has been applied in the train line planning of Wuhan-Guangzhou high-speed railway line and proved to be very effective in reducing the complexity of the train service planning problem.
