Unplanned Breakdown Maintenance It refers to the reactive maintenance performed when equipment or machinery unexpectedly fails. This type of maintenance occurs without prior warning, disrupting operations and leading to unplanned downtime. It requires immediate attention to repair or replace the faulty equipment to restore normal functionality. It is often more costly and time-consuming than preventive maintenance because it involves emergency repairs, unexpectedly labor costs, and potential production losses.
Planned Breakdown Maintenance A type of maintenance strategy where certain non-critical equipment is intentionally allowed to operate until it breaks down. The decision is made when it is more cost-effective to repair or replace the equipment after failure rather than perform regular preventive maintenance. Resources such as spare parts, tools, and labor are prepared in advance to address the failure when it occurs. This strategy typically applies to equipment that is inexpensive, easily replaceable, or does not significantly impact overall operations when it fails.
