摘要
以轨道交通枢纽为研究对象,通过建立换乘设施串并联系统,分析了系统中串联、并联单元的可靠性对系统整体可靠性的影响。定义某一设施的可靠性是乘客在该设施上延误时间为0的概率,据此建立可靠性函数模型。并根据可靠性函数值随各参数变化曲线分析各参数对可靠性的影响。研究结果表明:系统中串联设施越多,可靠性越低,并联的数量越多,可靠性越高。连接类设施的可靠性受设施宽度及乘客到达率的影响,服务类设施的可靠性受设施平均服务率及乘客到达率的影响。
Taking the rail transit terminal as the research object, the effects of the reliability of the serial units and the parallel units in the system on the reliability of the global system were analyzed through the establishment of the serial and parallel systems in the transfer facility. The reliability of the facility was defined as the probability that the passenger delay time is 0, and a reliability function model was built for the facility. The effects of parameters on the reliability were analyzed based on the reliability function versus parameters curves. The results indicate that the more serial units are in the system, the lower the system reliability is, and the parallel units are on the contrary. The reliability of the connection facility is affected by the width of facility and the passenger arrival rate, and the reliability of the service facility is affected by the average service rate of facility and the passenger arrival rate.
