Car Maintenance
A motor vehicle service or tune-up is a series of maintenance procedures carried out at a set time interval or after the vehicle has traveled a certain distance. The service intervals are specified by the vehicle manufacturer in a service schedule and some modern cars display the due date for the next service electronically on the instrument panel. A tune-up should not be confused with engine tuning, which is the modifying of an engine to perform ''better'' than the original specification, rather than using maintenance to keep the engine running as it should. Common tasks involved in maintaining a vehicle * Inspection - vehicle components are visually inspected for wear or any leaks. A diagnostic is performed to identify any electrical components reporting a failure or a part operating outside of normal conditions. * Replacement - Given certain lubricants break down over time due to heat and wear, manufacturers recommend replacement. Any parts that are close to their expected fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Predictive Maintenance
Predictive maintenance techniques are designed to help determine the condition of in-service equipment in order to estimate when maintenance should be performed. This approach promises cost savings over routine or time-based preventive maintenance, because tasks are performed only when warranted. Thus, it is regarded as condition-based maintenance carried out as suggested by estimations of the degradation state of an item. The main promise of predictive maintenance is to allow convenient scheduling of corrective maintenance, and to prevent unexpected equipment failures. The key is "the right infor equipment lifetime, increased plant safety, fewer accidents with negative impact on environment, and optimized spare parts handling. Predictive maintenance differs from preventive maintenance because it relies on the actual condition of equipment, rather than average or expected life statistics, to predict when maintenance will be required. Typically, Machine Learning approaches are ado ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planned Maintenance
The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure, and supporting utilities in industrial, business, and residential installations. Over time, this has come to include multiple wordings that describe various cost-effective practices to keep equipment operational; these activities occur either before or after a failure. Definitions Maintenance functions can defined as maintenance, repair and overhaul (MRO), and MRO is also used for maintenance, repair and operations. Over time, the terminology of maintenance and MRO has begun to become standardized. The United States Department of Defense uses the following definitions:Federal Standard 1037C and from MIL-STD-188 and from the Department of Defense Dictionary of Military and Associated Terms * Any activity—such as tests, measurements, replacements, adjustments, and repairs—intended to retain or restore a fun ...

Corrective Maintenance
Corrective maintenance is a maintenance task performed to identify, isolate, and rectify a fault so that the failed equipment, machine, or system can be restored to an operational condition within the tolerances or limits established for in-service operations. Definition A French official standard defines "corrective maintenance" as maintenance which is carried out after failure detection and is aimed at restoring an asset to a condition in which it can perform its intended function (NF EN 13306 X 60-319 standard, June 2010). Corrective maintenance can be subdivided into "immediate corrective maintenance" (in which work starts immediately after a failure) and "deferred corrective maintenance" (in which work is delayed in conformance to a given set of maintenance rules). Standards The technical standards concerning corrective maintenance are set by IEC 60050 chapter 191 °Dependability and quality of service" The NF EN 13306 X 60-319 is a subset of IEC 60050-191.

Software Maintenance
Software maintenance in software engineering is the modification of a software product after delivery to correct faults, to improve performance or other attributes. A common perception of maintenance is that it merely involves fixing defects. However, one study indicated that over 80% of maintenance effort is used for non-corrective actions. This perception is perpetuated by users submitting problem reports that in reality are functionality enhancements to the system. More recent studies put the bug-fixing proportion closer to 21%. History Software maintenance and evolution of systems was first addressed by Meir M. Lehman in 1969. Over a period of twenty years, his research led to the formulation of Lehman's Laws (Lehman 1997). Key findings of his research conclude that maintenance is really evolutionary development and that maintenance decisions are aided by understanding what happens to systems (and software) over time. Lehman demonstrated that systems continue to evolve ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rail Tracks
A railway track (British English and UIC terminology) or railroad track (American English), also known as permanent way or simply track, is the structure on a railway or railroad consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade. It enables trains to move by providing a dependable surface for their wheels to roll upon. Early tracks were constructed with wooden or cast iron rails, and wooden or stone sleepers; since the 1870s, rails have almost universally been made from steel. Historical development The first railway in Britain was the Wollaton Wagonway, built in 1603 between Wollaton and Strelley in Nottinghamshire. It used wooden rails and was the first of around 50 wooden-railed tramways built over the next 164 years. These early wooden tramways typically used rails of oak or beech, attached to wooden sleepers with iron or wooden nails. Gravel or small stones were packed around the s ...

Motive Power Depot
The motive power depot (MPD) or locomotive depot, or traction maintenance depot (TMD), is the place where locomotives are usually housed, repaired and maintained when not being used. They were originally known as "running sheds", "engine sheds" or, for short, just sheds. Facilities are provided for refuelling and replenishing water, lubricating oil and grease and, for steam engines, disposal of the ash. There are often workshops for day to day repairs and maintenance, although locomotive building and major overhauls are usually carried out in the locomotive works. (Note: In American English, the term ''depot'' is used to refer to passenger stations or goods (freight) facilities and not to vehicle maintenance facilities.) German practice The equivalent of such depots in German-speaking countries is the ''Bahnbetriebswerk'' or ''Bw'' which has similar functions, with major repairs and overhauls being carried out at ''Ausbesserungswerke''. The number of these reduced drastic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bus Garage
A bus garage, also known as a bus depot, bus base or bus barn, is a facility where buses are stored and maintained. In many conurbations, bus garages are on the site of former car barns or tram sheds, where trams (streetcars) were stored, and the operation transferred to buses. In other areas, garages were built to replace horsebus yards or on virgin sites when populations were not as high as now. Description Most bus garages will contain the following elements: *Internal parking *External parking *Fueling point *Fuel storage tanks *Engineering section *Inspection pits *Bus wash *Brake test lane *Staff canteen/break room *Administration office Smaller garages may contain the minimum engineering facilities, restricted to light servicing capabilities only. Garages may also contain recovery vehicles, often converted buses, although their incidence has declined with the use of contractors to recover break-downs, and the increase in reliability. Overnight, the more valuable or regu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maintenance Of An Organism
Maintenance of an organism is the collection of processes to stay alive, excluding production processes. The Dynamic Energy Budget theory delineates two classes * Somatic maintenance mainly comprises the turnover of structural mass (mainly proteins) and the maintenance of concentration gradients of metabolites across membranes (e.g., counteracting leakage). This is related to maintenance respiration. * Maturity maintenance concerns the maintenance of defence systems (such as the immune system), and the preparation of the body for reproduction. The theory assumes that maturity maintenance costs can be reduced more easily during starvation than somatic maintenance costs. Under extreme starvation conditions, somatic maintenance costs are paid from structural mass, which causes shrinking. Some organism manage to switch to the turpor Torpor is a state of decreased physiological activity in an animal, usually marked by a reduced body temperature and metabolic rate. Torpor enables ani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
