Backgroundthe result of a long knowledge acquisition process started in the forties (e.g. design of the FMECA approach). Until now, many related approaches have been developed (e.g. HAZOP, fault trees, Markov or Petri net techniques) to improve the analyses. Based on a probabilistic approach, they prove to bearchaeology 发表于 2025-3-25 14:39:25
Reliability Study Overviewon) of the study. When this is done, it is of utmost importance to understand how the system works (.) before trying to find out how it can fail (.). This chapter explains how to do that for qualitative, semi-quantitative or purely quantitative analyses by using the various available approaches. TheALERT 发表于 2025-3-25 16:09:33

Mathematical Frameworkraphical models such as reliability block diagram, fault tree, event tree, etc. It also provides the basic definitions of events and operators (NOT, OR, AND) used within the Boolean algebra framework.

Reliability Block Diagrams (RBDs) describes its position within the probabilistic approaches in general and the Boolean family approaches in particular. This is a directed acyclic graph drafted by using specific symbols (blocks) and logic structures (series, parallel, majority vote). It aims to model how a system is in up state (i.Commonwealth 发表于 2025-3-26 17:45:38
Fault Tree Analysis (FTA)y and dependability modelling. This chapter describes its position within the probabilistic approaches in general and the Boolean family approaches in particular. It aims to model how a system is faulty (i.e. in down state) from the logic combination of the faults (i.e. down states) of its component
