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, 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 ...
Preventive maintenance or preventative [16] maintenance (PM) has the following meanings: The care and servicing by personnel for the purpose of maintaining equipment in satisfactory operating condition by providing for systematic inspection, detection , and correction of incipient failures either before they occur or before they develop into ...
Military maintenance philosophy versus commercial. Military systems and large commercial systems share reliability constraints. The ability to for a military system to continue operating after battle damage is survivability. Military Maintenance Policy (MMP) is required for defense systems. Designs typically include redundancy with automatic ...
Military logistics is the discipline of planning and carrying out the movement, supply, and maintenance of military forces. In its most comprehensive sense, it is those aspects or military operations that deal with: Design, development, acquisition, storage, distribution, maintenance, evacuation, and disposition of materiel. Transport of personnel.
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 ...
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.
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.
