摘　　要：研究了具有修理延迟的两不同部件并联可修系统,假定部件的寿命服从指数分布,延迟修理时间和部件的修理时间服从一般连续型分布,通过使用补充变量法和广义马尔可夫过程方法,得到了系统的可靠度的Laplace变换、首次故障前平均时间、稳态可用度和稳态故障频度等重要可靠性指标。This paper deals with the two-dissimilar-unit paralleled repairable system with delay repair. It is assumed that the life of the unit is exponential distribution;the repair time of the unit and the delay repair time are general continuous distributions. By using the supplementary variables approach and generalized Markov process method, the Laplace transforms of the reliability and the mean time to first failure are attained. Meanwhile, the availability and the failure frequency of the system are obtained.
