Industrial maintenance is divided into four categories: reactive maintenance (emergency repair after failure), preventive maintenance (replacement on a fixed cycle), condition-based maintenance (deciding whether to intervene based on real-time monitoring indicators), and predictive maintenance (using models to predict remaining useful life or failure probability and give timing recommendations).

Condition-based maintenance (CBM) is a strategy of scheduling maintenance based on the actual health state of equipment rather than a fixed timetable, and the key difference from traditional preventive maintenance is that the latter replaces parts periodically according to the calendar or operating hours.
