WebbBayesian PHM algorithm augmented with the RJMCMC approach to model selection. High temperatures (usually in excess of 550°C) and variable loading profiles may cause a structural component to fail catastrophically due to thermal creep, when accumulated over long time frames (several years). WebbRefined analytical methods are developed in [13] for the cost-benefit analysis of canarybased PHM and in [22,23] to maximize the system resilience, which is defined as a combination of...

WebbPHM algorithms. Field data only are generally not informative enough for the purpose of designing a PHM algorithm with adequate performance:-Time for degradation excessively long, evolution difficult to track. Therefore Prototyping approach is proposed to address the issue of lack of representative data.

The early lack of standardized methods for performance evaluation and benchmark data-sets resulted in reliance on conventional performance metrics borrowed from statistics. Those metrics were primarily accuracy and precision based where performance is evaluated against end of life, typically known a priori in an offline setting.
