| 摘 要： | 分组列车与单组列车是我国车流组织的两种形式,二者互有利弊,对其开行适用条件研究具有理论价值和现实意义。根据固定车组重量分组列车集结的动态特性和车组到达的不确定性,将车组的车数和间隔时间都视为随机变量,应用随机过程理论,解析其在编成站和途中换挂站的集结耗费相对于单组列车的节省和额外消耗,以一昼夜所产生的总净节省的数学期望作为其综合效益的度量,给出分组列车合理开行的判别式和更易判定的必要条件。针对模型的特点,应用离散事件系统仿真方法进行模拟。仿真算例表明:判定条件的吻合率为97.36%,必要条件的失真率为4.52%;其综合效益受到车组平均车数和平均间隔时间参数影响且前者灵敏程度更高;适用于车流量较小且车流到达强度之比接近固定车组重量之比情形。
