摘　　要：[目的]分析高速列车运行模式及高速列车在运行过程中受到的多种外界干扰,在区间通过能力临时失效干扰的前提下,为高速列车运行调整提供一种可行的建模及求解方法。[方法]确定高速列车运行调整优化的目标函数,结合高速列车运行的实际情况,将列车运行调整过程转化成相应约束条件,建立区间通过能力临时失效条件下高速列车运行调整混合整数线性规划模型。同时,设计滚动时域算法对模型分阶段进行求解,力争在较短时间内给出调整方案。[结果]基于部分京沪高速铁路列车运行图数据,对所提出的模型与算法进行仿真验证与分析。[结论]仿真试验证明,采取调整方法可有效减小干扰对列车运行秩序的影响。[Purposes]This paper analyzes the high-speed train operation mode and various external disturbances during the operation of high-speed trains,and proposes a feasible modeling and solution for high-speed train operation adjustment under the premise of temporary failure interference of section capacity.[Methods]The objective function of high-speed train operation adjustment optimization is determined.Combined with the actual situation of high-speed train operation,the train operation adjustment process is transformed into corresponding constraints,and the mixed integer linear programming model of high-speed train operation adjustment under the condition of temporary failure of interval capacity is established.At the same time,the rolling time domain algorithm is designed to solve the model in stages,in order to make an adjustment scheme in time.[Findings]Based on the train diagram data of Beijing-Shanghai high-speed railway,the proposed model and algorithm are verified and analyzed by simulation.[Conclusions]The simulation results show that the adjustment method can effectively reduce the influence of interference on the train operation order.
