Chapter Chapter 4 in Reliability Assessment of Safety and Production Systems, 2021, pp 43-101 from Springer

Abstract: Abstract A sound corpus of concepts, terms and definitions is needed to achieve relevant reliability assessments of safety and production systems. Some of the terms and concepts have been introduced a long time ago and have, little by little, drifted from their original definitions and this is a problem. The aim of this chapter is to identify the many specific concepts related to safety and dependability useful to reliability engineers and to explain, clarify and discuss them when needed. This encompasses the states (up/down, operating/non-operating, degraded, critical restoration), the failures and faults (definitions, classification, modes, common cause, critical), the maintenance (definitions, repair, restoration, repaired and non-repaired items) and the probabilistic concepts (random processes, reliability/availability, failure rate/intensity, maintainability). Acronyms (MUT/MDT, MTTF, MTTFF, MTBF) are analysed in detail specially these which, suffering from the biggest semantic drifts (MTTF and MTBF), have become meaningless. After a thorough analysis, more relevant acronyms (e.g. mean operating time to operating failures, MTTFO, and MTBF related to operating failures, MTBFO) and definitions are provided.
