摘　　要：列车在枢纽站的合理接续关系到旅客换乘质量,更对铁路运输企业的收益具有重要影响。针对枢纽站列车接续的到发时刻优化问题,在分析列车的接续关系和旅客换乘方式的基础上,以换乘旅客的无效换乘等待时间最小为目标,考虑列车间隔时间、合理到发时间、换乘时间等约束,构建枢纽站列车接续的到发时刻优化模型。最后利用CPLEX求解器对算例进行求解,换乘旅客的无效换乘等待时间较优化前减少了16.8%。结果表明,建立的列车接续优化模型能够有效减少旅客换乘的无效换乘等待时间,提升列车接续质量。The reasonable train connection in junction stations relates to passenger transfer quality and has an important impact on the income of railway transport enterprises.To optimize the arrival-departure time for train connection in junction stations,an arrival-departure time optimization model for train connection in junction stations was established for the purpose of minimizing the invalid transfer waiting time for passengers based on the analysis of train connection relationship and passenger transfer mode,after considering such constraints as train headway,reasonable arrival-departure time and transfer time.Finally,the CPLEX solver was used to solve examples,obtaining a result that the invalid transfer waiting time of passengers is reduced by 16.8%compared with that before optimization.This shows that the established optimization model for train connection can effectively reduce the invalid transfer waiting time of passengers and improve the train connection quality.
