The goal of an equipment reliability program is to effectively monitor equipment, procedures, and data covering the life of equipment. Find another word for reliability. This permits reliability, i.e. reliability definition: 1. the quality of being able to be trusted or believed because of working or behaving well: 2. the…. Identification of Failure Modes – The goal of most maintenance strategies is to prevent or predict equipment failures. At the end of the day, each of these measurements has a financial impact on the organization. The development of computer technology makes it easier to sort the data and analyze the failure mode of the failure. Reliability Centered Maintenance (RCM) is a process that ensures maintenance tasks are performed in an efficient, cost-effective, reliable, and safe manner. As we have seen, understanding the definition of reliability is extremely important for any scientist but, for social scientists, biologists and psychologists, it’s a crucial foundation of any research design.In psychometry, for example, the constructs being measured first need to be isolated before they can be measured. Design-out is used to engineer high reliability parts into machines, plant and equipment because the risks associated with the failure are too expensive to accept. B. include the associated equipment's information from the asset management system." Articles in this issue should cover activities used to assess the current capabilities of equipment and processes in terms of their reliability, availability, maintainability and criticality. • MTTF (Mean time to failure, years, hours) – more correct for items that are not repaired ... By definition, a dangerous undetected failure will not be apparent until either a demand comes along or it is revealed by a proof test. The measurement of equipment system reliability in this Document concentrates on the relationship between equipment system failures and equipment system usage. the overall reliability of equipment. "equipment reliability, availability and maintainability" can be abbreviated as ERAM. One of the definitions of ERAM is "equipment reliability, availability and maintainability".
