Abstract
Some aspects of a system operation dynamics may prevent excellence in organizations performance. This is imperative for mission-oriented systems since all necessary interventions have to be undertaken during the stoppages between successive missions. Maintenance models that deal with it, however, do not take into account that aspects, such as the length of stoppages or constraints on the maintenance resources. These constraints limit the set of actions that can be carried out during each stoppage. Thus, it should be selected the maintenance actions that would best improve system performance, observing constraints. Traditionally, models that address this issue seek to optimize one of the performance indicators of a system. Thus, an original contribution of this paper is to optimize conflicting indicators through a multicriteria perspective by considering the preferences of the decision maker. Therefore, it has been used FITradeoff (Flexible and Interactive Tradeoff) method in order to asses a global performance value to each alternative. At last, the obtained plan is compared to the one obtained in a traditional way.
