Phm algorithm
Prognostic performance evaluation is of key importance for a successful PHM system deployment. 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. More recently, efforts towards m… http://papers.phmsociety.org/index.php/phme/article/view/1373

WebbThe Prognostics Algorithm Library is a suite of algorithms implemented in the MATLAB programming language for model-based prognostics (remaining life computation). It includes algorithms for state estimation and prediction, including uncertainty propagation. 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).
