Productivity is a key weapon for manufacturing companies to stay competitive in a continuous growing global market. Increased productivity can be achieved through increased availability. This has directed focus on different maintenance types and maintenance strategies. Increased availability through efficient maintenance can be achieved through less corrective maintenance actions and more accur...

We develop a matrix algebra approach for optimizing condition-based maintenance with planning time gradually deteriorating, continuously monitored equipment. This avoids the calculation times of simulation and approximations more direct approaches. consider model in which after failure should be planned as well, resulting downtime, emergency repairs upon failure. Numerical examples are provided...

In this paper we consider a k-out-of-N system with identical, repairable components under a condition-based maintenance policy. Maintenance consists of replacing all failed and/or aged components. Next, the replaced components have to be repaired. The system availability can be controlled by the maintenance policy, the spare part inventory level, the repair capacity and repair job priority sett...

The deterioration law of the system will usually be assumed to be Markovian, that is, the future process of the system depends only on its state at the present time and not on its past history. This model has been suggested by Klein [1]. There are at least two good reasons for describing deterioration by a Markov model. Firstly, if each component is approximately subject to an exponential failu...

This paper is concerned with the development of a realistic preventive maintenance (PM) scheduling model. A heuristic approach for implementing the semi-parametric proportional-hazards model (PHM) to schedule the next preventive maintenance interval on the basis of the equipment’s full condition history is introduced. This heuristic can be used with repairable systems and does not require the u...
