An engine system consists of three main components in a series, all having the same reliability.
Determine the level of reliability required for each of the components if the engine is to have a
reliability of 0.998.
(Round your answer to 4 decimal places, the tolerance is +/-0.0005)
Solution
Since failure in one component brings down the whole engine we can multiply the
separate (equal) reliabilities r^3 = 0.998 r = 0.9993 If the tolerance is on the components, and
you need to be absolutely sure that system reliability is at least 0.998, then you would need to
raise the reliability of each component by 0.0005.
