Purpose–The purpose of this paper is to review the literature on maintenance optimization
models and associated case studies. For these optimization models critical observations are …

Reliability analysis considering multiple possible states is known as multi-state (MS)
reliability analysis. Multi-state system reliability models allow both the system and its …

Many systems are required to perform a series of missions with finite breaks between any
two consecutive missions. In such a case, one of the most widely used maintenance policies …

A dynamic preventive maintenance policy for system with continuously degrading
components is investigated in this paper. Different from traditional cost-centric preventive …

In engineering scenarios, failures of some components in a system may not always lead to
the failure of an entire system. In such cases, the system can continuously operate while …

A multi-state system (MSS) has more than two discrete states corresponding to different
performance rates. Usually, MSS is viewed as in a failure state once its performance rate …

This paper proposes a multi-threshold image segmentation method based on modified salp
swarm algorithm (SSA). Multi-threshold image segmentation method has good …

In this paper, we consider a serial production line consisting of nn unreliable machines with
n-1 n-1 buffers. The objective is to determine the optimal preventive maintenance policy and …

This paper presents a maintenance optimisation method for a multi-state series–parallel
system considering economic dependence and state-dependent inspection intervals. The …

In this paper, the great deluge algorithm (GDA), which has not been previously used in
constrained mechanical design optimization problems is employed to solve several design …
