PHM is a multi-faceted approach which links studies of failure mechanisms to system life-cycle management and predicts when an object system will no longer perform its intended function. Actions are then implemented based on the prediction of the state of health derived from health monitoring and expected future use of the system.
In the recent past, PHM-enabled predictive maintenance solutions were focused on complex systems (or systems of systems), such as automotive, railway transportation, and avionics, for which failure would be catastrophic. Often, those systems involved the compilation of massive amounts of historical data, the application of machine learning, and the creation of a digital ?twin,? a digital rendition of the physical machine that would perform virtually like its physical counterpart. However, the ubiquity of sensors (e.g., there are 300,000 sensors in the new generations of aircraft) leads to the need for efficient processing and a relevant interpretation to gain insights from the massive volume of data. That is, synergies between the Internet of Things (IoT), data analytics, and risk assessment will ultimately determine the success of PHM.
This graduate course at the University of Maryland is one of the few in academia that covers the concepts and theory of PHM along with the latest applications. With real-life examples from academia, industry, and government, students learn and apply the latest PHM methods and tools.
CLASS TIME
9:30 AM?12:10 PM on Mondays (US Eastern) in Room 2216, J. M. Patterson Building (Bldg. 083). The class is open to graduate students, upper-level undergraduate students, and industry professionals.
