Condition-based maintenance is performed only when the need arises, usually in response to a deviation from normal operation of a Technical Object. It is based on the use of real-time data through sensors and trend analysis to continuously monitor the technical condition. Through continuous monitoring, an automated system observes the functioning of the Technical Object and action is taken only when necessary. It depends on the collection of historical data for the technical object in question. The current state is then continuously compared to a historical baseline. This baseline is used as a reference point for system failures.
Challenges of condition-based maintenance are:
