Prognostics and Health Management of Complex Systems

The confluence of recent advancements in sensor technology, information technology, probabilistic inference methods, physics of failure sciences, and complex system modeling offers the foundation for the next major push in realizing on-line, real-time condition monitoring, diagnostics, and prognostics for complex hybrid systems. The strong momentum in this direction is evidenced by the formation of research groups in prognostics and health management (PHM), creation of professional societies, and active interest and initiatives by various industries as well as the public sector. Other domains of interest and natural extensions are, “fault-adaptive controls”, and “methods for identifying and analyzing failure precursors”. Broad topics of research pursued at the Garrick Institute include (1) large scale complex system PHM technology development, and (2) model-based integration of diagnostics and prognostics for reliability and safety.
