独立指数情形下n中取k系统的极限行为

Limit Characterization for k-out of-n System with Independent Exponential Components

讨论了当各元件相互独立并具有互不相同的指数分布时 n中取 k系统的极限行为 ;利用有关开关更新过程的极限理论获得了该系统的极限平均故障时间间隔、极限平均停工时间长度和极限平均工作时间长度的确切计算公式 .

The k out of n system with mutually independent but not identical exponentially distributed com ponents is dealt with. By the limit theory of the alternating renewal process, w e obtain the accurate formulas of the limit mean time between failures, the limi t mean down time and the limit mean work time, as the functioning tim e of the system tends to infinity.
