7 Reliability and Availability of Repairable Components and Systems

DOI: 10.1201/9781003307495-7

When we perform reliability studies, it is important to distinguish between repairable and nonrepairable items. The reliability analysis methods discussed in Chapters 3–5 largely apply to nonrepairable items. In this chapter, we examine the critical aspects of repairable systems and discuss methods used to determine the failure characteristics of these systems, and the methods for predicting their reliability and availability.

Nonrepairable components and systems are discarded or replaced (i.e., taken out of their sockets and replaced) with new ones when they fail. For example, light bulbs, transistors, contacts, satellites, and some small appliances ...
