Systems maintainence - Research Paper Example Theoretically, a reliable product is completely free of any technical errors. In practical world, there is no an ideal system (Huo, Zhang, Wang, & Yan, 2005). The reliability-Centred Maintenance Reliability-Centred Maintenance, simply called RCM is a system improvement approach that focuses on identifying and fixing the maintenance, operational and capital enhancement policies that would manage the dangers of equipment failure in the most effective way (Hauge & Johnston, 2001). It is a framework that facilitates the definition of a total maintenance regime. It considers maintenance as the means through which the functions required by a user are met. As a discipline, RCM enables machinery stakeholders to observe, predict, asses, and in general terms understand the working of their practical assets (Douglas & Greg, 1997). This is included in the first part of the RCM procedures that involves identifying the operating context of the given system, and document a Failure Mode Effects and Critically Analysis Applying the â€Å"RCM logic† is the second part of the analysis, which helps to establish the suitable maintenance tasks for the spotted failure modes of FMECA. Immediately the logic is complete for the entire FMECA elements, the outcome of the maintenance are â€Å"packed† in order for the task periodicities to be rationalized and be called up in the work packets. However, it is vital not to demolish the maintenance applicability at this stage. Lastly, it is advisable for RCM to be kept live during the entire â€Å"in-service† machinery life, where the efficiency of the maintenance is reviewed constantly and adjusted as per the experience obtained (Douglas & Greg, 1997). The RCM method can be used to recognize the most effective way to utilize resources for medical system maintenance. It involves spotting out actions that when applied, will decrease the possibility of failure and that are more cost-friendly. It seeks the best mix of Conditi on-founded actions, a Run-to Failure, or Time-or-Cycle-Based operations approach. Reliability-Cantered Maintenance is a continuous process that collects data on uses and performance of data to enhance planning for maintenance in future. These maintenance methods, rather than being used independently, are put together to take advantage of their respective powers to optimise equipment/departmental operation and competence within a particular resource constraint (Huo, Zhang, Wang, & Yan, 2005). RCM approach employs Planned Preventive Maintenance (PPM), repair, proactive maintenance methods, and Predictive Testing and Inspection. (PT&I) techniques are an integrated way to increase the likelihood that a medical component or device will work in the required way over its design life-cycle. The aim of this approach is to offer the required availability and reliability at the lowest cost possible. It necessitates that maintenance decisions be founded on the requirements justified by economic and technical support. Like for any approach, there are numerous processes or paths that lead to an eventual end. This is especially a reality for RCM, where the results of failure can differ dramatically (Hauge & Johnston, 2001). Define supportability and how it is used in the system design process Supportability refers to the level to which the design features of a support or standby system meet the operational needs of a firm (Yu, Li, Jia, & Li, 2012).

Geographical Information Systems - Term Paper Example While a definition of what constitutes GIS is central to discussing its role within geography, such a definition is, in fact, difficult to produce since the term is used so variable by different people, some using it to refer to a single system while others use it to designate a system of barely related subsystems (Pickles, in Pickles, 1995, p. 3). Pickles (1995) states that all geographic information systems have two central defining characteristics: They involve the use of digital electronic data and the production of electronic spatial representations (p. 3). Parker (in Castle, 1993, p. xvii) goes even further in simplifying the defining aspect of GIS as being nothing more than data handling  which any mention of geography per se can easily be dropped. Such a bare-bones definition of GIS lends it an appearance of neutrality that is deceptive, for geographers use electronic information technology forward a variety of epistemological perspectives and research goals. Pickles (1995) summarizes the field of possible applications; it should be noted that within each of these possible applications a wide range of philosophies and motivations is possible. [GIS is} a research community that transcends disciplinary boundaries; an approach to geographical inquiry and spatial data handling; a series of technologies for collecting, manipulating, and representing spatial information; a way of thinking about spatial data; a commodified object that has monetary potential and value; and a technical tool that has strategic value (p. 3). Not only is GIS multifaceted in its technical capabilities, it is multidimensional in its social and cultural capabilities as well, allowing for new demographic tools, new forms of workplace domination, novel commodities, new ways of identifying space and nature and new ways of waging war (Pickles, in Pickles, 1995, p. 4).
