Maintenance strategies selection modeling for naval systems

Abstract

This paper presents a qualitative Maintenance Strategies Selection Model for Naval Systems based on basic RCM (Reliability Centered Maintenance) principles taking into consideration particularities of a warship and maintenance in former Serbian and Montenegro Navy. Due to the lack of statistic data on maintenance and failures, we used expert knowledge of naval systems operators and maintainers. Creation of a specific model was also necessary due to the lack of engineering resources and time for all the required analysis of complex technical items. Additional problem was a need to extend the ship´s life cycle. With a purpose to make rational use of the resources for the analysis of all complex systems of the ship, three different approaches have been modeled depending on whether some experience in the previous maintenance exists and on the amount of their maintenance costs. Pilot-analyses conducted against this model showed its applicability and potential to reduce maintenance costs of ship´s systems.
