摘要:
针对马尔可夫的单部件可修系统的不足,假设部件寿命和故障修复时间都遵从一般分布,对非马尔可夫的单部件可修系统的可用状态进行了定义,将临界修复时间分为正常数和非负随机变量两类进行分析,得出了新模型的系统瞬时可用度,从而更加准确地反映了该类系统的效能。最后,通过一组数值试验对新模型和原系统的瞬时可用度进行了比较。结果表明,得到的新模型能更准确地刻画系统的可用情况。
Abstract:
In view of the shortage of a single-unit Markov repairable system,assuming the lifetime and repair time are random variables with general distributions,this paper defines the available state of the single-unit non-Markov repairable system.The critical repair time is considered into two classes.One is a constant and the other is a non-negative random variable.An instantaneous availability model of the new system is built,which can describe the system performance more accurately.Some numerical examples are given to compare the instantaneous availability of the former and the later model,concluding that the later is better than the former in instantaneous availability.
