摘要
客运专线旅客列车开行方案是旅客列车运营组织工作的重要组成部分,必需经历运量预测、方案优化和运行图编制3个阶段。其中,OD客流的预测及分析,是旅客列车开行方案制定的前提和基础,而运行图的编制则属于方案的具体实施。研究中对3个阶段的子问题采取单独顺序优化、循环迭代的方法解决客运专线旅客列车开行方案优化问题。同时,提出了保证该研究路线可行性的必备条件,以及整体循环迭代过程是否收敛的理论关键。
The train running scheme of dedicated passenger line is an important part of passenger train operation and organization; so it is significant to find methods on exploring its scheme optimization. The complete scheme should be formed through three steps： traffic volume forecast, running scheme optimization and then drawing the running diagram. The forecast and analysis of OD passenger flow, thereinto, are the precondition and foundation of the scheme establishment. And drawing of the passenger train diagram is execution of the scheme. The paper puts forward a thought that using outer recurrent iteration to achieve the harmonized optimization of the interior three approaches. The method of sequentially optimizing and recurrent iterating the sub-issues of the three approaches separately is adopted to solve the optimization problem of the train running scheme of dedicated passenger line. Furthermore, the paper puts forward the necessary condition for ensuring the line feasibility, and akey theory point that guarantees convergence of the iteration process.
