摘　　要：在李太勒公式的基础上,利用单通道和多通道M|D|n经典排队模型,确定了旅客平均排队队长、最大等待时间、扶梯服务强度之间的相互联系,建立了等待时间计算模型。结合中国某特大型客运站A站的旅客发送数据,在候车时间概率分布模型的基础上,按照等待时间的不同,对旅客发送最多日、节假日和普通工作日的扶梯配置、功率和能耗进行了细致分析,比较研究了等待时间为5、10、30s时的固定能耗和可变能耗。分析结果表明,候梯时间的设置影响扶梯的配置和扶梯能耗,扶梯能耗中固定能耗占70%,可变能耗占30%。Our research is based on the Little Formula and the classical queuing model of multi-channel M /D In. The escalator allocation and the influencing factors of the energy consumption are studied. The relations between the average queue length, the maximum waiting time and the escalator service intensity are obtained. The waiting time simulation model is built. The passenger delivery data at a railway station in China is used. With the probability distribution model of waiting time, an analysis is made on the escalator allocation, power and energy consumption on three kinds of working days, that is, holidays, ordinary working days and the largest-passengers-volume days. Meanwhile, the fixed and variable energy consumption rates for different waiting times are compared. For example, the waiting time can take values of 5, 10 and 30 seconds. The result shows that the waiting time settings affect the allocation of the escalators and the energy consumption of the escalators. The fixed energy consumption takes 70% of the whole. Variable energy consumption takes 30%.
