Abstract

Adopts IEC 61078, Ed. 3.0 (2016), which describes the requirements that apply when reliability block diagrams (RBDs) are used in dependability analysis. It also describes the procedures for modelling the dependability of a system with RBDs.

Scope

This International Standard describes:
- the requirements to apply when reliability block diagrams (RBDs) are used in dependability analysis;
- the procedures for modelling the dependability of a system with reliability block diagrams;
- how to use RBDs for qualitative and quantitative analysis;
- the procedures for using the RBD model to calculate availability, failure frequency and
- reliability measures for different types of systems with constant (or time dependent)
- probabilities of blocks success/failure, and for non-repaired blocks or repaired blocks;
- some theoretical aspects and limitations in performing calculations for availability, failure frequency and reliability measures;
- the relationships with fault tree analysis (see IEC 61025 [1]) and Markov techniques (see IEC 61165 [2]).
