摘要
本文主要研究n中取k系统失效元件数量的问题。首先,本文考虑了在t时刻并联系统正常运行时,得出失效元件为r(r=0,1,...,n-1)的概率,并且研究了一些随机序的性质,然后进一步扩展到n中取k系统中。
In this paper,the number of failed components in a k-out-of-n system is studied.Firstly,we consider the parallel system operating normally at time t and calculated the probability that r fails,r=0,1...,n=1.Secondly,the properties of some stochastic orders are investigated.Furthermore,the results of k-out-of-n system are extended.
