This chapter addresses the approximate calculation of the probability that a functional requirement will exceed a particular acceptance limit. The chapter discusses such calculations in a general way in order to present a set of ideas that are also valid for calculating the probability of failure associated with a certain failure mode for a component.
5.1 Objective of reliability calculations
In Chapter 3, Axiomatic Design was discussed as a general design tool. Axiom 2 in particular, regarding information content, leads to the design of systems with a minimum number of functional requirements (Corollary 2), and sets the broadest acceptance intervals ...
