Availability Model of a PHM-Equipped Component

Résumé

—A variety of prognostic and health management (PHM) algorithms have been developed in the last years and some metrics have been proposed to evaluate their performances. However , a general framework that allows us to quantify the benefit of PHM depending on these metrics is still lacking. We propose a general , time-variant, analytical model that conservatively evaluates the increase in system availability achievable when a component is equipped with a PHM system of known performance metrics. The availability model builds on metrics of literature and is applicable to different contexts. A simulated case study is presented concerning crack propagation in a mechanical component. A simplified cost model is used to compare the performance of predictive maintenance based on PHM with corrective and scheduled maintenance. Index Terms—Availability, cost-benefit analysis, Monte Carlo (MC) simulation, prognostics and health Management (PHM) metrics.
