摘要：AbstractThis paper deals with a proactive maintenance strategy used to increase the reliability of the equipment. A predicting schedule of the renewal interventions is proposed so as to ensure optimal equipment maintenance. Hence, the goal is to find the optimal time which is the most profitable to carry out the equipment renewal operations. For the optimization of the maintenance, the preventive strategy is based on the average maintenance cost. The deterioration process is modeled by a Markov model, which is able to provide information about the tendency of the equipment state. The considered case study is an actuator, used in the sugar industry. A parametric form of the random behavior of the main variables was added to the Markov model, in the particular case of this actuator.
