The reliability of the system is: RS (t) = 1 – (1 – R1 (t)) × (1 – R2 (t)). Assuming that the failure rates are constant, the reliability of each component is: Ri (t) = exp (- λi × t).

WebThe outline of the chapter is as follows: Section 4.1 defines basic concepts of reliability, like functions, failures, and failure modes and effects. Section 4.2 introduces reliability measures and lifetime models with focus on the exponential and Weibull models. System … WebMain directions of modern reliability theory are briefly described: probabilistic modeling, statistical analysis, optimization of maintenance and sparing. History of development of ideas in reliability theory is reviewed from W.Weibull and B. Gnedenko works up to recent time. A brief survey of significant publications in the area is given.
