摘要
探讨城际通道短距离多线路列车优化问题,建立城际通道高速列车开行方案优化模型,提升列车运输效益和服务水平。针对城际通道线路特点,以多线路、多列车类型为基础构造列车流路径网络;分析旅客出行费用偏差,将客票费用偏差和旅行时间费用偏差相结合考虑,通过引入旅客对不同因素的容忍度参数,提出旅客出行需求与运输供给的协同偏差,进而建立供需协同的城际通道列车开行方案优化模型。以模拟退火算法为基础,设计模型求解算法。最后通过算例进行仿真验证,结果表明,利用该方法得到的开行方案,能在满足旅客需求条件下,在列车运输效率、运营收益和服务质量方面得到一定程度的提高,从而为高速铁路列车开行方案优化提供新思路。
The optimization problems of short distance and multi-line trains in intercity corridors are explored to build the optimization model for high speed train operation plans in intercity corridors for improving train transportation efficiency and service levels.Based on the characteristics of intercity corridors with multiple lines and train types,a train flow path network was constructed.The deviation of passenger travel costs was analyzed by considering the deviation of ticket costs and travel time costs.The cooperative deviation between passenger demand and transportation supply was proposed by introducing parameters that expressed passengers’varying tolerance levels for different factors to build an optimization model for train operation plans in intercity corridors.Based on the simulated annealing algorithm,a solving algorithm was designed and validated through experiments.The results show that the train operation plan using the proposed optimal model can improve train transportation efficiency,operational revenue,and service quality while considering passenger demand satisfaction.It is beneficial to achieving the new idea of train operation plan optimization.
