研究了有修理延迟的两个不同部件和两个修理工组成的冷贮备系统.假定部件的工作寿命服从一般分布,故障后的延迟修理时间和修理时间均服从指数分布.利用马尔可夫更新过程、拉普拉斯变换和拉普拉斯-司梯阶变换工具,得到了系统的首次故障前时间、可用度和平均故障次数等可靠性指标.
The cold storage system consisting of two different parts with delay and two mechanics is studied, the working life of the part is assumed to be general distribution, and the delay repair time and repair time after failure are both exponentially distributed.Using Markov renewal process, Laplace transform and Laplace - Stages transformation tools, the reliability index of the system such as the time before first failure, the availability and the average number of failures is obtained.
