Answers
The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure, and supporting utilities in industrial, business, governmental, and residential installations.Over time, this has come to include multiple wordings that describe various cost-effective practices to keep equipment operational; these activities take place either before or after a failure. Together, these functions are referred to as Maintenance, repair and overhaul (MRO). MRO is also used for Maintenance, repair and operations.
Types:
The basic types of maintenance falling under MRO include:[10]
Preventive maintenance, also known as PM
Corrective maintenance where equipment is repaired or replaced after wear, malfunction or break down.
Predictive maintenance, which uses sensor data to monitor a system, then continuously evaluates it against historical trends to predict failure before it occurs.[11]
Reinforcement[12]
Architectural conservation employs MRO to preserve, rehabilitate, restore, or reconstruct historical structures with stone, brick, glass, metal, and wood which match the original constituent materials where possible, or with suitable polymer technologies when not.
