            Methods Of Maintenance

[John Mitchell, Machinery Analysis and Monitoring, 1993, p. 485-486]

• PREDICTIVE >  Predictive maintenance is defined as maintenance actions, e.g. repairs, overhauls and component replacement based on assessment of machinery condition through condition monitoring techniques

• PREVENTIVE > Preventive or calendar time-based maintenance is accomplished at fixed time intervals regardless of condition

• REACTIVE > Reactive or breakdown maintenance is the default alternative if problems aren't detected and corrected prior to machinery failure. This is the most expensive of the three, however perhaps justifiable on small nonvital machinery
