This paper presents a condition-based maintenance policy taking into account both maintenance cost and production capacity aspects for single unit deterioratin production system whose condition is periodically monitored. Imperfect preventive maintenance activities, which restore the production system to better states and might not be as good as new, are considered. We assume however that the sy...

The use of prognostic methods in maintenance in order to predict remaining useful life is receiving more attention over the past years. The use of these techniques in maintenance decision making and optimization in multi-component systems is however a still underexplored area. The objective of this paper is to optimally plan maintenance for a multi-component system based on prognostic/predictiv...

We present a model to determine the optimal point for maintaining a software application. We also address the question: given that a maintenance project has been initiated, should maintenance effort continue till the project is completed? Most previous literature has implicitly assumed that it is optimal to complete a maintenance project once it has been initiated. We analyze two policies: a wo...

With the evolution of technology, the maintenance of sophisticated systems is of concern for system engineers and system designers. The maintenance cost of the system depends in general on the replacement and repair policies. The system replacement may be in a strictly periodic fashion or on a random basis depending upon the maintenance policy. At failure, the repair of the system may be perfor...

Employing maintenance threshold plays a critical step in determining an optimal policy for offshore wind system to reduce costs while increasing reliability. Considering the limited works on this topic, we propose two-stage procedure determine thresholds multiple components of power order minimize achieving highest possible First, using genetic algorithms, dynamic strategy is developed individu...

Maintenance and, in particular, maintenance policy plays a major -*art in achieving systems operational effectiveness at minimkm cost. The traditional approach to maintenance planning involves selecting optimal policies from known maintenance strategies such as scheduled inspection, preventive maintenance, corrective maintenance, oncondition maintenance etc. Using a traditional approach one may...

many serious accidents have happened in the world, in which systems have been large-scale and complex, and caused heavy damage and a social sense of instability. furthermore, advanced nations have almost finished public infrastructure and rushed into a maintenance period. since maintenance is more important than production and construction, then more maintenance for environmental considerations...

This article presents a case study determining the optimal preventive maintenance policy for a light rail rolling stock system in terms of reliability, availability, and maintenance costs. The maintenance policy defines one of the three predefined preventive maintenance actions at fixed time-based intervals for each of the subsystems of the braking system. Based on work, maintenance, and failur...
