Operational maintenance is the care and minor maintenance of equipment using procedures that do not require detailed technical knowledge of the equipment’s or system’s function and design. This category of operational maintenance normally consists of inspecting, cleaning, servicing, preserving, lubricating, and adjusting, as required.
Maintenance functions can be defined as maintenance, repair and overhaul (MRO), and MRO is also used for maintenance, repair and operations. [4] Over time, the terminology of maintenance and MRO has begun to become standardized. The United States Department of Defense uses the following definitions: [5]
In particular, Ethernet operations, administration and maintenance (EOAM) is the protocol for installing, monitoring and troubleshooting Ethernet metropolitan area network (MANs) and Ethernet WANs. The OAM features covered by this protocol are discovery, link monitoring, remote fault detection and remote loopback .
O-level maintenance is typically optimized for quick turn-around, to enhance operational availability. Maintenance at this level typically consists of immediate remove and replace (R&R) operations that replace failed (unserviceable) LRUs with spare (serviceable) assets taken from inventory. Repair-in-place (RIP) procedures are also common.
Maintenance, testing, and inspection schedules are required to ensure that the facility is operating safely and efficiently in compliance with statutory obligations, to maximize the life of equipment, and to reduce the risk of failure. The work is planned, often using a computer-aided facility management (CAFM) system.
Operations management covers sectors like banking systems, hospitals, companies, working with suppliers, customers, and using technology. Operations is one of the major functions in an organization along with supply chains, marketing, finance and human resources. The operations function requires management of both the strategic and day-to-day ...
The procedures associated with periodic maintenance are generally called a Periodic Maintenance System (PMS). There is risk that the system will not work as expected, and this risk grows as time passes due to increasing possibility of silent faults that cause operational failure. Periodic maintenance actions control risk of operational failure.
A maintenance engineer should possess significant knowledge of statistics, probability, and logistics, and in the fundamentals of the operation of the equipment and machinery he or she is responsible for. A maintenance engineer should also possess high interpersonal, communication, and management skills, as well as the ability to make decisions ...
