TLDR
The probability that there are exactly i, $$i=0,\ldots ,n-k,$$ failures in a k-out-of-n system under the condition that it is operating at time t, is computed.Abstract:
In this paper, we study the number of failed components of a coherent system. We consider the case when the component lifetimes are discrete random variables that may be dependent and non-identically distributed. Firstly, we compute the probability that there are exactly i, $$i=0,\ldots ,n-k,$$
failures in a k-out-of-n system under the condition that it is operating at time t. Next, we extend this result to other coherent systems. In addition, we show that, in the most popular model of independent and identically distributed component lifetimes, the obtained probability corresponds to the respective one derived in the continuous case and existing in the literature.read more

On the number of failed components in a coherent system consisting of multiple types of components
TL;DR: In this paper , the authors investigated the number of failed components in an operating coherent system, where the system consists of components having non-identical failure time distributions and formulated the optimization problem to determine the optimal values of the number and arrangement of components of each type.

A study on the number of failed components in a failed coherent system consisting of different types of components
TL;DR: In this article , the authors considered a coherent system consisting of different types of components and studied the number of failed components of each type when the system fails. And they formulated the optimization problem to find the optimal replacement time.

TL;DR: A number of new classes of life distributions arising naturally in reliability models are treated systematically and each provides a realistic probabilistic description of a physical property occurring in the reliability context, thus permitting more realistic modeling of commonly occurring reliability situations.
