摘要
提速干线上编组站到解系统作业特点是到达列车流不均衡。运用排队论和随机过程理论,定量分析系统出现饱和状态的条件,即驼峰作业负荷达到临界负荷,输入流强度的增加,将导致到解系统在临界密集到达时间内进入饱和状态。临界负荷主要取决于到发线数量和驼峰作业时间变异系数。临界密集到达时间受到达流强度、变异系数、驼峰作业负荷等因素的影响。改善编组站到解系统匹配与协调关系的措施有:建立有效的生产作业保障机制,优化车流组织方案,增加编组站设备数量等等。
The operation characteristics of a marshalling station declassification system is the unbalanced status of arrival train flows. The queueing theory and stochastic process are used to analyze quantitatively the condition for the appearance of saturation in the system, in which hump-working load arrives at the critical value. The declassification system will come into the saturated state within the time of the arrival of critical intensity if input flow intensity increases. Critical load is mainly determined by the number of receiving and departure track and coefficient of variation of hump-working time. The critical intensity arrival time is influenced by input flow intensity, coefficient of variation, hump-working load, etc. The measures to improve the matching and coordinating relationship are to set up an effective guarantee mechanism of production, optimize the organization scheme of car flow, increase the number of equipment in the marshalling station, etc.
