Abstract

In spite of the science of Reliability is old in the time, there is often misunderstanding about the various terms used in this field. This is a real situation in many contexts, also for high technology industrial and practical applications. The aim of this Chapter concerns an overview of the most important terms correlated with Dependability, that is a qualitative performance of an item such as a component, a device, an equipment, and so on. Referring to the International Standard, Dependability is defined, in fact, as the collective term used to describe the availability performance and its influencing factors: reliability, maintainability and maintenance support performance. On the basis of this definition, it is evident that dependability gives a general description of the item in non-quantitative terms. To express its performance in quantitative terms and thus to describe, measure, improve, guarantee and certify such an item, it is necessary to establish the characteristics of reliability, availability, maintainability and maintenance support performance. Such terms are defined in this Chapter.
