This paper studies maintained systems with nonself-announcing (" hidden") failures that
deteriorate due to both shocks and graceful degradation. Shocks occur according to a …

This article presents hybrid, degradation-based reliability models for a single-unit system
whose degradation is driven by a semi-Markov environment. The primary objective is to …

Engineers design systems to be reliable and work to fulfil their missions without failure for a
specific period. However, the system components deteriorate with time and lead to its …

The availability of systems undergoing periodic inspections is studied in this paper. A perfect
repair or replacement of a failed system is carried out requiring either a constant or a …

We analyze a periodically inspected system with hidden failures in which the rate of wear is
modulated by a continuous-time Markov chain and additional damage is induced by a …

We present transient and asymptotic reliability indices for a single‐unit system that is subject
to Markov‐modulated shocks and wear. The transient results are derived from the …

In this paper, we introduce and analyze simple, new inspection policies for maintaining
deteriorating equipment with non-self-announcing failures. These policies utilize information …

Providing customers with efficient maintenance policies is of great interest to suppliers of
complex industrial equipment and devices. Generally, developing such policies requires a …

This paper studies inspected systems with non-self-announcing failures where the rate of
deterioration is governed by a Markov chain. We compute the lifetime distribution and …

An inspection scheme is an integral part of any maintenance policy and we usually have to
determine the time points at which the system should be inspected to make sure that the …
