Remaining Useful Life (RUL) of Component or System

Remaining Useful Life (RUL) is the estimated time that a system or component can continue operating before it reaches failure or no longer meets performance standards, requiring repair or replacement. The ability to predict the RUL of an asset enables effective maintenance strategies that can prevent catastrophic failures and reduce downtime in industrial machinery. This is a central strategy in prognostics and health management (PHM) that improves the safety and reliability of a system while lowering operational and maintenance costs. The RUL prediction can be of a system or component.
