Selective maintenance considering two types of failure modes

International Journal of Strategic Engineering Asset Management (IJSEAM), Vol. 2, No. 1, 2014

Abstract: Owing to limited maintenance resources, it may not be possible to perform all feasible maintenance actions on a system during the maintenance break between two successive missions. A subset of maintenance actions can then be selected from the available maintenance options so that the system can meet the next mission requirement. This maintenance policy is called selective maintenance. In this paper, selective maintenance has been performed for a system that has been subjected to the two types of failure modes: maintainable and the non-maintainable failure modes. The hazard rate due to the maintainable failure modes depends on the cumulative effect of the non-maintainable failure modes. A model has been used to show this relationship. An illustrative example has been used to demonstrate the effect of the two failure modes and the advantages of imperfect maintenance in selective maintenance decision making.
