ABSTRACT

This chapter covers the methods for assessing the failure probability of components and systems. The failure probability can be computed based on the survival events defined as the complements of the respective underlying failure events using survival probability computations or reliability analysis. Both analytical and empirical methods can be used for this purpose at the component level or the multicomponent discretized system level. This chapter discusses how to select an appropriate method, compute the probabilities of interest, and model time-variant reliability and correlations among basic random variables, and provides illustrative examples. It has a primary learning objective to develop basic skills for modeling the performance of components and systems as a basis to quantify nonperformance probabilities.
