摘要
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.
A two different components and two repairmen of a cold standby system with delay repair are studied. Assumed that the working life of components is subject to general distribution, and the delay fault repair time and repair time are exponential distributions. By using Markov renewal process, the Laplace transform and the Laplace-Division ladder transform, the system reliability indices such as the first failure time of system, availability and the average failure frequency are obtained.
