摘　　要：为评估高铁枢纽站点线能力的协调性,运用排队论相关理论,构建了线路区间、车站咽喉、车站到发线为服务子系统的高铁枢纽点线系统多阶串联排队模型,考虑服务水平,提出了各阶服务子系统的随机概率分布模型及参数。以列车排队等待时间、排队列车数为负向指标,通过列车数为正向指标,对高铁枢纽站各阶服务子系统进行排队仿真,并运用熵权法进行点线系统的协调度计算。最后,采用实际数据进行验证。结果表明,所提方法可以为高铁枢纽站点线系统协调定量性判定提供科学依据。In order to evaluate the node and line capacity coordination of high-speed railway hub, a multi-stage queuing model of high-speed railway hub with section, station throat and arrival-departure track as service subsystems is constructed by using queuing theory. Considering the service level, the stochastic probability distribution model and parameters of each service subsystem were proposed. On the basis above, taking the waiting time and the number of trains in the queue as negative indicators and the number of trains as positive indicators, the queuing simulation of each service subsystem of high-speed railway hub station was carried out, and the coordination degree of the node-line system was calculated by using entropy weight method. Finally, the actual data were used for verification. The results show that the proposed method can provide a scientific basis for the coordinated quantitative determination of the high-speed rail hub station line system.
