The predicted period during which an asset is expected to continue performing its intended function before functional failure occurs.
Remaining Useful Life (RUL) is the estimated period during which an asset, component or system is expected to continue performing its intended function before reaching a failure condition or requiring replacement. RUL predictions commonly use condition monitoring, operational data, degradation models and prognostic algorithms to support predictive maintenance and asset lifecycle optimization.
Remaining Useful Life predicts how long an asset is expected to continue operating before functional failure or replacement becomes necessary.
Remaining Useful Life is widely used in predictive maintenance and prognostics to optimize maintenance scheduling, reduce unplanned failures and improve asset utilization.
Remaining Useful Life predicts future operational life using condition and prognostic information, whereas Remaining Life is a broader engineering estimate based on inspection, degradation and integrity assessments.
