Objective: The aim of this systematic review was to identify factors that influence reliability and to provide an evidence base for promoting consistent and reliable application of the GCS. Unplanned downtime results into undesirable indirect cost of maintenance due to losses in production and the idleness of other machines in the production system. affect the … Lewis, P, Schwarz, H, and Waldron, W. RELIABILITY FACTORS AFFECTING POWER PLANT MECHANICAL EQUIPMENT..Canada: N. p., 1971. To help with the research, a case study was conducted at BMSC. A. ROWSE Water Resources Board, Reading Bridge House, Reading RG1 8PS, England Abstract--It has been the painful experience of most users of automatic hydrometric instruments, that the equipment appears … Unplanned downtime results into undesirable indirect cost of maintenance due to losses in production and the idleness of other machines in the production system. Is the probability that an asset, item, or unit will perform its prescribed duty without failure for a given time in a specified environment. This framework consists of creating a vision and mission, ensuring availability of resources and empowering people to achieve organizational excellence. There will then be a dual effect on OEE due to improved reliability. These two factors are often abbreviated as MTBF (mean time between failures) and MTTR (mean time to recovery). 23 0 obj <> endobj This paper therefore, aims at identifying potential causes of Dump Truck downtime in order to establish a Framework that could be used as a tool by management to proactively identify breakdown causes and make informed decisions. performance is about response time - how fast a message can be sent or how quickly a document can be retrieved. Before diving into the reliability program key elements, we must understand the meaning of equipment reliability. Research Paper | Mining | Zambia | Volume 9 Issue 6, June 2020, Exploring Factors that Affect Reliability of Open Pit Heavy Mining Dump Trucks: A Case of Bisha Mining Share Company, Eritrea, Achieving high production and productivity target is one of the core focus areas of the mining industry today in order to stay in business. The reliability of the measures are affected by the length of the scale, definition of the items, homogeneity of the groups, duration of the scale, objectivity in scoring, the conditions of measuring, the explanation of the scale, the characteristics of the items in scale, difficulty of scale, and reliability estimation method. Reliability and maintainability are two factors that are heavily influenced by maintenance. Identifying and understanding factors that can affect its reliability is important, in order to promote high standards for clinical use of the GCS.

However, it does include explanations of some statistics commonly used to describe test reliability. It can be said that a system must be reliably safe. For example, if a professional footballer was to perform a 40-m sprint test using timing gates it may render an ICC of 0.75, but the same 40-m sprint in high school athletes using a stopwatch will be much lower. Factors that affect the performance of networks. %PDF-1.6 %âãÏÓ OSTI.GOV Conference: Factors that affect reliability of nondestructive detection of flaws in structural ceramics Understanding how reliability and maintainability affect … Further, quantitative data was analysed by the use of descriptive statistics from the Likert scale and graphs and tables have been used to highlight trends of data results. %%EOF 175 to 179 Pergamon Press, 1974.

This video is part of our online course on Reliability and Validity Assessment of a Measure. important factors that have a high effect on the accuracy of estimation (i.e. RAO: INFLUENCE OF ENVIRONMENTAL FACTORS ON COMPONENT/EQUIPMENT RELIABILITY 123 occur. Following factors affects the reliability of audit evidence: The reliability of audit evidence is increased when it is obtained from independent sources outside the entity. Equipment reliability assures that subsystems and components function as intended without failure for desired periods during their design life. Reliability and Maintainability characteristics; Meantime Between Failure (MTBF) and Meantime To Repair (MTTR) as well as failure mode patterns have been examined in order to identify the key sources of Truck downtime. Qualitative data was analysed through the inductive process of building from the data to broad themes and then proceeding to interpretation. Inadequate data quality management processes.
