摘　　要：编组站能力与运行图能力的协调是一个动态的点线能力协调过程。根据不均衡运输条件下的点图能力特点,设置状态随机变量,对编组站的到解、编组和出发3个作业子系统的动态作业过程进行描述。根据3个子系统的车流接续关系,推导出点图能力协调的状态转移方程,并给出系统协调的约束条件,用协调度定量描述点图系统的动态协调关系。The coordination of marshalling station capacity and train diagram capacity is a dynamic capacity coordinating process between stations and lines. According to the characteristics of capacity of station and diagram under unbalanced transportation condition, through setting the status random variables, the paper describes the dynamic operation process of three operation subsystems in marshalling station, which are receiving and discomposing, marshalling and departure. According to the wagon flow relation in the three subsystems, the state transition equation of station and diagram capacity coordination is achieved, the restriction conditions of system coordination are provided, and the dynamic coordination relationship of station and diagram system is described quantitatively by using coordination ratio.
