摘　　要：铁路编组站有定编发车和定点发车两种货物列车发车模式。为确定定点发车模式中最小编成辆数的模型,对发车模式的条件进行了一定的假设,研究了两种模式的相关运行指标,找出了其基本变化规律。提出定点发车模式中有利最小编成辆数、效益最小编成辆数、成本最小编成辆数、能力最小编成辆数和模型最小编成辆数5个概念,并给出了相应变量的确定方法。研究表明,定点发车模式适宜于车流量小、运行区间距离短的车流方向。There are two kinds of departure mode of freight train in marshalling station, which are fixed-point departure mode and fixed-consist departure mode. In order to determine the model of minimum number of care in fixed-point departure mode, this paper gives some assumptions on the condition of the departure mode, studies the operation index about the two departure modes and finds out the basic change principle. Furthermore, the paper puts forward five concepts, which include favorable minimum number of cars, benefit minimum number of cars, cost minimum number of cars, capacity minimum number of cars and model minimum number of cars, and gives the determination method of the variables corresponding to the five concepts. The study shows that the fixedpoint departure mode of freight train is adapted better to the condition of smaller vehicle flow and shorter distance of running section.
