In the design of any system, the design variables and parameters are probabilistic in nature. Thus, it is obvious that the factors that determine the stress and strength of the components are also probabilistic. This means that when the reliability aspects of design are evaluated, the probabilistic nature of the variables and parameters for a system must be considered. The probabilistic approaches to design and reliability are discussed in Chapter 4. Chapters 5 and 6 expand on the methodology necessary to analyze complex designs from a reliability standpoint. Specifically, Chapter 5 discusses combining random variables in design and presents concepts useful in statistical tolerancing. This chapter exposes the student to the further statistical work needed for design reliability. Chapter 6 presents the techniques for determining design reliability after the probabilistic modeling of design variables and parameters. In Chapter 7 simple design examples are used to illustrate the design reliability methodology. The more advanced problem of time-dependent stress-strength models is developed in Chapter 8. Dynamic reliability models are discussed in Chapter 9 along with concepts for maintainability. In the evolution of a new product, the testing comes after the design is complete. Thus, Chapters 10 and 11 consider the problem of reliability estimation from test data. Specifically, Chapter 10 uses the exponential distribution as the underlying model and presents reliability estimation techniques for a variety of situations. Similarly, in Chapter 11 the Weibull distribution is used as the model for product life. Chapter 12 is concerned with the development of sequential tests for reliability demonstration. Chapter 13 develops the new area of Bayesian statistical inference as it applies to product testing.
