考虑效能的高铁旅客列车运行线布局优化研究

Research on Optimization of High-Speed Passenger Train Operation Line Layout Considering Efficiency and Benefit

随着高速铁路成网建设,在以跨线运营为主的既有运输组织模式下,繁忙干线区段能力紧张、路网整体效能不足的问题逐渐突出。列车运行图是反映客流需求情况、决定企业效率效益的重要运行生产计划,而列车运行线布局优劣直接影响了运行图的编制质量。跨线列车运行线应满足跨线客流对于始发、终到时刻的要求,而本线列车运行线则应匹配高峰时段充足的本线客流需求。考虑上述差异,以跨线乘客期望始发终到时间满意度最大和高峰时段相邻跨线列车间可插入本线列车数量最多为目标构建优化模型,采用模拟退火算法求解,并通过实例进行验证。结果表明,优质时段内本线及跨线列车间存在竞争性,应结合需求选取适宜的方案。模型对于协调本线及跨线客流对运力资源占用的竞争关系,实现流线匹配的目标提供了一定的参考。

With the construction of high-speed railway network, under the existing transport organization mode mainly based on cross line operation, the problems of tight capacity of busy trunk sections and insufficient overall efficiency and benefit of the railway network are gradually prominent. Train operation diagram is an important operation and production plan to reflect the passenger flow demand and determine the efficiency and benefit of enterprises, and the quality of train diagram is directly affected by the quality of train operation line layout. The operation line of cross line trains should meet the requirements of cross line passenger flow for departure and arrival times, while the operation line of this line should match the sufficient passenger flow demand of this line during peak hours. Considering the above differences, the optimization model is constructed aiming at the maximum expected satisfaction of cross line passengers and the maximum number of trains can be inserted between adjacent cross line trains during peak hours. The model is solved by simulated annealing algorithm and verified by an example. The results indicate that there is competition between trains on this line and cross line trains during high-quality time periods, and the appropriate scheme should be selected according to the demand. The model provides a certain reference for coordinating the competition between the passenger flow of this line and cross-line and realizing the goal of streamline matching.
