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 .
Metrics in operations management can be broadly classified into efficiency metrics and effectiveness metrics. Effectiveness metrics involve: Price (actually fixed by marketing, but lower bounded by production cost): purchase price, use costs, maintenance costs, upgrade costs, disposal costs; Quality: specification and compliance
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.
Reliability-centered maintenance (RCM) is a concept of maintenance planning to ensure that systems continue to do what their users require in their present operating context. [1] Successful implementation of RCM will lead to increase in cost effectiveness, reliability, machine uptime, and a greater understanding of the level of risk that the ...
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.
