摘　　要：研究了修理延迟且修理设备可更换的两同型部件冷贮备系统.假定部件寿命、修理时间、修理延迟时间均服从一般分布,且修理设备寿命为指数分布,更换时间为一般分布,利用马尔可夫更新过程理论,讨论了系统的首次故障前时间、可用度和平均故障次数等可靠性指标,获得重要结果.This paper considers a two-unit same cold standby system with delay repair and a replaceable facility.Assuming that the working life,the repair time and the delay repair time are general distributions,and the repair facility＇s life has exponential distribution and its repair time has general distribution,some main reliability quantities,such as the system＇s availability and the expected failure number,are analyzed by Markov renewal process theory.Some important reliability results are obtained.
