“…[29] aims to identify the dominated subsystem-level strategies incurring a high maintenance cost and a low production rate in stochastic ordering. In another word, the new method considers the whole system, while the method in Ref.…”

“…Moreover, the performance of a multistate system can be described more accurately by the distribution of production rates instead of a single scalar value (i.e., reliability). Zhou et al [29] proposed a strategy space reduction method based on stochastic ordering to address this issue. In their work, the subsystem-level strategies causing a high maintenance cost and a low production rate in stochastic ordering were excluded during the optimisation process.…”

“…Although the method presented in Ref. [29] can significantly reduce the strategy space, the criterion used to eliminate inappropriate subsystem-level strategies considers only the current subsystem. Nonetheless, influence of subsystem-level maintenance strategies on the objective function of maintenance optimisation also depends on the maintenance strategies of other subsystems.…”

a b s t r a c tAdvances in sensor technology have enabled companies to make significant progress towards achieving condition-based maintenance (CBM). CBM provides the opportunity to perform maintenance actions more effectively. However, scheduling maintenance at the unit level may imply a high maintenance frequency at the asset level, which can be costly and undesirable for safety reasons. In this paper, we consider systems consisting of multiple critical units for which a strict and conservative maintenance strategy is enforced. Although this implies that benefits cannot be obtained by delaying maintenance activities, the clustering of them can be beneficial. We consider two simple, practical systems for condition monitoring that involve either one signal (alarm) or two signals (alert, alarm). Our analysis and results provide general insights into when and how to cluster maintenance operations, with the objective of minimizing the total maintenance costs. Moreover, they show that clustering is essential for a broad range of circumstances, including those at a considered real-life case of equipment maintenance at Europe's largest gas field.

“…Perfect PM aims to make the system as good as before starting to work, while imperfect PM may bring the system back to an intermediate state between the current state and the perfect functioning state [22]. In some papers like [23,24], a multi-state system with the state-dependent cost was investigated. In [25], a deteriorating repairable multi-state system with an imperfect policy was o ered based on the number of system failures.…”

A Multi-Objective Multi-State Degraded System to Optimize Maintenance/Repair Costs and System Availability

Abstract. In this study, a multi-state degraded system is studied, where status of system is continuously degrading over time. As time progresses, system may either deteriorate gradually and go to lower performance state, or it may fail suddenly. If the system fails, some repairs are carried out to restore the system to the previous state. When the inspections reveal that the system has reached its last acceptable state, a PM is carried out to restore the system to the higher performance states. The goal is to nd the optimal PM level, so that the mean availability of the system is maximized and the total cost of the system is minimized. In this regard, Markov process is employed to represent di erent states of system. An integrated optimization approach is also suggested based on the desirability function of statistical approach. The suggested aggregation method is robust to the potential dependency between the total cost and the mean availability. It also ensures that both objective functions fall in decision-maker's acceptable region. In order to show the e ciency of the proposed approach, a numerical example is presented and analyzed.
