Abstract:

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.
