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 ...
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, 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.
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.
The main focus in occupational health is on three different objectives: (i) the maintenance and promotion of workers' health and working capacity; (ii) the improvement of working environment and work to become conducive to safety and health and (iii) development of work organizations and working cultures in a direction which supports health and ...
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.
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.
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
