摘要： 研究了两个同型主部件组成的,Birolini,系统,并带有一个无优先权的冷贮备备用部件组成的三部件可修系统.假定部件的寿命服从指数分布、部件的修理时间服从一般连续型分布,通过补充变量法和广义马尔可夫过程方法,得到了系统可靠度的\,Laplace\,变换、首次故障前平均时间、稳态可用度与稳态故障频度等重要可靠性指标.

Abstract: This paper deals with Birolini's duplex system sustained by a non-priority unit in cold standby. It is assumed that the life of the unit is exponential distribution, and the repair time of the unit is general continuous distribution. Then by using supplementary variables approach and generalized Markov process method, the Laplace transform of the reliability and the mean time to first failure are attained. Meanwhile, the availability and the failure frequency of the system are obtained.

Key words: priority rule, Birolini's duplex system, reliability, generalized Markov process
