Current studies have shifted from the analysis of single-layer network to multi-layer network.
However, the performance of multi-layer networks has been significantly influenced by …

In many cases, the safety and the reliability of a warm standby system heavily rely on the
successful activation and the subsequent operation of its standby components. Optimal …

The parallel structure in the reliability engineering is widely used in many industrial systems
such as power generation systems, pump systems, production systems and computing …

Weighted k-out-of-n systems form an important class of redundant systems with a wide
range of applications in reliability engineering. In this paper, we introduce novel optimal …

Real-world systems are often exposed to shocks likes earthquakes and hurricanes during
service life, and these shocks may occur multiple times. However, existing studies lack …

Motivated by real-world applications of cloud computing and unmanned aerial vehicles
(UAVs), this paper models a heterogeneous 1-out-of-n standby system with n components …

In this paper, we study some preventive maintenance policies for coherent systems with n,
n⩾ 1, components. We consider a coherent system consisting of K, K⩾ 1, different types of …

In many industrial and technological systems, due to factors such as deterioration, corrosion,
attacks, etc., preventive replacement is typically performed according to a predetermined …

In reality, a system and its components, apart from internal failures, are often exposed to
external shocks as well. Since external shocks have significant effects on the performance of …

We propose optimal preventive maintenance strategies for n-component coherent systems.
We assume that in the early time of the system operation all failed components are repaired …
