Final answer:
Maintenance dedicated to repairing failed equipment is termed 'corrective maintenance'. It differs from preventive and predictive maintenance, as it reacts to issues after they occur, aiming to restore function.
Step-by-step explanation:
Maintenance performed to fix equipment that has failed is called corrective maintenance. This type of maintenance addresses issues as they arise rather than preventing them beforehand. The main goal is to restore the equipment to its proper working condition after a failure has occurred. In contrast, preventive maintenance is scheduled based on time or usage to prevent equipment failures before they occur. And predictive maintenance uses technology to monitor the condition of equipment and predict when maintenance should be performed. Routine maintenance is the regular, day-to-day work that is done to keep equipment in good working order, which doesn't necessarily correspond to an immediate repair response like corrective maintenance does.
