摘　　要：对由两个不同型部件组成的、有优先权的、开关寿命为连续型随机变量的冷贮备可修系统 ,在两部件的工作时间和维修时间以及转换开关的寿命和修理时间均服从指数分布、所有随机变量均相互独立、工作部件的寿命分布与其贮备时间无关、故障部件和转换开关均可修复如新的条件下作了研究 ,建立了该类系统的一般模型 。This paperpresents the reliability analysis of the cold standby repairable system of two compo- nents with continuous lifetime switch and priority,under the condition thatthe operating time and main- tained time of two components and the lifetime and repair- time of switch are all exponential distribu- tions.All the variables are independent,and the lifetime of operating components have nothing to do with its maintained time,and the failure components and switch can be as good as new after repair.We set up a model of this kind of system,so the reliability R( t) and other steady- state reliability indexes are ob- tained.
