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 ...
Software maintenance is the modification of software after delivery. Software maintenance is often considered lower skilled and less rewarding than new development. As such, it is a common target for outsourcing or offshoring. Usually, the team developing the software is different from those who will be maintaining it.
Optimal maintenance is the discipline within operations research concerned with maintaining a system in a manner that maximizes profit or minimizes cost. Cost functions depending on the reliability , availability and maintainability characteristics of the system of interest determine the parameters to minimize.
Important data stored on computers may be copied and archived securely so that, in the event of failure, the data and systems may be reconstructed. When major maintenance such as patching is performed, a backup is recommended as the first step in case the update fails and reversion is required.
This analysis drives the maintenance support for each repairable unit analyzed. LORA is the most important physical supportability analysis business decision made during acquisition of a system. [why?] LORA is performed in two steps (SAE Standard AS1390A): Establish noneconomic decision criteria used to make initial support decisions
The key factor as to when and why this work is being done is timing, and involves a service, resource or facility being unavailable. [18] [19] By contrast, condition-based maintenance is not directly based on equipment age. Planned maintenance is preplanned, and can be date-based, based on equipment running hours, or on distance travelled.
Maintenance, and hence maintenance engineering, is increasing in importance due to rising amounts of equipment, systems, machineries and infrastructure. Since the Industrial Revolution , devices, equipment, machinery and structures have grown increasingly complex, requiring a host of personnel, vocations and related systems needed to maintain ...
In telecommunications and several other engineering fields, the term maintainability has the following meanings: . A characteristic of design and installation, expressed as the probability that an item will be retained in or restored to a specified condition within a given period of time, when the maintenance is performed by prescribed procedures and resources.
