Operational Availability Assessment for Improving the Maintenance of the Complex Systems

Abstract Several modelling methods have been proposed in the production research field in order to improve the complex industry profitability. During the last few years, the availability concept can't be ignored for these industries, which want to reduce the maintenance costs and maximize the operational availability. In this way, the availability studies are the central object of our problematic. Our article is dealing with the system maintenance modelling in order to maximize operational availability systems. A study case based on aeronautical systems will be presented for illustrating the proposed method.
