摘　　要：区别于传统的两部件冷储备系统,考虑带有预防维修的两同型部件的冷储备系统的问题,根据马氏更新过程、半马氏过程及L变换、LS变换等理论算出3种可靠性指标,可以看出,两部件型的带有预防维修的冷储备系统相比其它传统冷储备系统来说,要计算相应结果较为困难,不能仅仅通过半马氏过程、马氏更新过程的理论对其分析,但可以利用上述理论得出常用的可靠性指标。Different from the traditional two unit cold standby system,we consider the cold standby system problems of the same type of two units with preventive maintenance,according to the theory of Markov renewal process,semi-Markov process,and L or LS transformation,we calculates the three kinds of reliability index,we can see that,the cold standby system problems of the same type of two units with preventive maintenance different from other the traditional cold storage system,it is difficult to calculate the corresponding results,not only through the the theory of Markov renewal process,semiMarkov process to analysis it,but we can get the common reliability index through the above theory.
