BS EN 61078:2016 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]).Cross References:IEC 60050-192IEC 61703EN 61703IEC 61025EN 61025IEC 61165EN 61165IEC 62551EN 62551IEC 60812EN 60812IEC 61508:2010EN 61508:2010IEC 61511:2016EN 61511:2016ISO/TR 12489CEN ISO/TR 12489Replaces BS EN 61078:2006 which remains currentAll current amendments available at time of purchase are included with the purchase of this document.
