Organizations should therefore map system reliability and availability calculations to business value and end-user experience. Decisions may require strategic trade-offs with cost, performance and,security, and decision makers will need to ask questions beyond the system dependability metrics and specificatio...

Since exact aggregation is only possible in ...
The measurement of Availability is driven bytime losswhereas the measurement of Reliability is driven by thefrequencyandimpactof failures. Mathematically, the Availability of a system can be treated as a function of its Reliability. In other words, Reliability can be considered a subset of Availabilit...
The last step involves computing the availability of the entire system. These calculations have been based on serial and parallel availability calculation formulas.

The five chapters of this book collect and illustrate techniques that have been applied to the prediction of reliability and availability of the various specific segments of an electric power system. The text emphasizes the numerical procedures employed in making these reliability and availability predict...
I think that i should calculate firts the mtbf of serial or parallel and mttr of serial or paralle and than the availability as the definition. Thanks Replies continue below Recommended for youIRstuff (Aerospace) 19 May 13 02:39 Your approach is mathematically correct. However, a few examp...
The availability calculations supported the hypothesis of the negative impact of the offshore environmental conditions on the reliability figures. Nonetheless, similarities in the reliability figures of the blade adjustment system and the maintainability of the power generation and the control systems are ...
The Availability calculations for the two months are exactly equal: 99.861% Uptime. But the Reliability for the two months is dramatically different: 2 outages vs 10 outages. Which month do you think would most upset the users? January User: Well, there were a couple of outages this month,...
