Methodology for assessing the probabilistic condition of an asset based in concepts of structural reliability “PCBM - Probabilistic Condition Based Maintenance”

The purpose of this paper is to propose a methodology for assessing the probabilistic condition of an asset with the introduction of the concept of PCBM (Probabilistic Condition Based Maintenance) as an extension of the existing concept CBM (Condition Based Maintenance). The concepts of structural reliability and its methods will be used to evaluate the structural integrity of a mechanical system. The evaluation will be held through the probability of failure of this system and its reliability index. The system will be subject to dynamic loads. From experimental results, simulations will be performed and the correlations between the probabilistic model and the deterministic will be conducted in order to verify the possibility of using this methodology to support the decision-making process.
