Chapter 11

Safety, Reliability, and Risk Assessment

Abstract

The definitions of safety and reliability and the means of apportioning mission reliability are discussed, and the reliability function is introduced. Failure rate models are used in the development of reliability estimates, and apportionment goals are evaluated. Propulsion system reliability is used as an example of estimating mission success. An overview of probabilistic risk assessment is presented and the question of functional failures is addressed using the Space Shuttle as an example. The Weibull distribution and its role in risk and reliability studies are described.
