半马尔可夫过程(semi-Markov process)马尔可夫链的一种推广
在容错控制系统的可靠性分析中，利用马尔可夫过程和半马尔可夫过程理论对容错系统进行可靠性建模能够较为真实地描述系统的实际工作情况。
In the reliability analyzing of such a system, Markov process and semi Markov process theory can be applied to describing the original working condition of the system.
它直观上可视作半动力系统随机中断(或出现问题)的时刻，亦可视作逐段决定马尔可夫过程的首次随机跳跃时刻。
In a sense, it can be seen as the time when semi-dynamic system is killed, or as the time the first random jump of piecewise deterministic Markov process.
