A Generic Prognostic Framework For Remaining Useful Life Prediction Of Complex Engineering Systems, Alexander V. Usynin Dec 2007

A Generic Prognostic Framework For Remaining Useful Life Prediction Of Complex Engineering Systems, Alexander V. Usynin

Doctoral Dissertations

Prognostics and Health Management (PHM) is a general term that encompasses methods used to evaluate system health, predict the onset of failure, and mitigate the risks associated with the degraded behavior. Multitudes of health monitoring techniques facilitating the detection and classification of the onset of failure have been developed for commercial and military applications. PHM system designers are currently focused on developing prognostic techniques and integrating diagnostic/prognostic approaches at the system level. This dissertation introduces a prognostic framework, which integrates several methodologies that are necessary for the general application of PHM to a variety of systems. A method is developed …


An Integrated Fuzzy Inference Based Monitoring, Diagnostic, And Prognostic System, Dustin R. Garvey May 2007

An Integrated Fuzzy Inference Based Monitoring, Diagnostic, And Prognostic System, Dustin R. Garvey

Doctoral Dissertations

To date the majority of the research related to the development and application of monitoring, diagnostic, and prognostic systems has been exclusive in the sense that only one of the three areas is the focus of the work. While previous research progresses each of the respective fields, the end result is a variable "grab bag" of techniques that address each problem independently. Also, the new field of prognostics is lacking in the sense that few methods have been proposed that produce estimates of the remaining useful life (RUL) of a device or can be realistically applied to real-world systems. This …
