Abstract:

The need for a Prognostics and Health Management (PHM) system is propelled by increasing demand for condition based maintenance for systems to reduce cost of maintenance and mitigate risk. The use of multiple algorithms for PHM for a variety of systems presents challenges for PHM system developers in terms of integration and interfacing of various components, including hardware and software. A PHM system comprises of several elements including sensors, computing hardware and software algorithms for fault detection, diagnostics, prognostics and decision support. Thus there is a need for an architectural framework to help system developers and integrators for faster system development and deployment.
