Rul Estimation: Predicting Asset Longevity

by

What is RUL?

Remaining Useful Life (RUL) refers to the estimated amount of time until an asset or component fails or loses its functionality. RUL estimation involves predicting the future behavior of an asset based on its current condition and historical data. Prognostics uses this information to predict potential failures and optimize maintenance strategies, leading to improved asset performance, reduced downtime, and increased safety.
