摘　　要：假定部件的寿命服从指数分布,其修理延迟时间和修理时间均服从一般分布,并且修理设备的寿命服从指数分布,其更换时间服从一般分布,利用马尔可夫更新过程理论和一种新的分解方法,研究了修理设备可更换且修理有延迟的两不同型部件并联可修系统,求得了系统和修理设备有关可靠性指标的一系列结果.This paper considers a two-different-units paralleled repairable system with a replaceable facility and repair delay. By assuming that the life of each unit has exponential distribution and both the repair time and repair delay time have general distribution, while the repair facility＇s life obeys exponential distribution and its repair time obeys general distribution, some primary reliability behaviors are obtained by using Markov renewal process theory and a new analytic approach--the decomposition method.

关 键 词：可修系统 修理延迟 马尔可夫更新过程 可用度 故障时间 故障次数
