Analysis techniques for dependability - Reliability block diagram and boolean methods

This International Standard describes procedures for modelling the dependability of a system and for using the model in order to calculate reliability and availability measures. The RBD modelling technique is intended to be applied primarily to systems without repair and where the order in which failures occur does not matter. For systems where the order of failures is to be taken into account or where repairs are to be carried out, other modelling techniques, such as Markov analysis, are more suitable.

Techniken für die Analyse der Zuverlässigkeit - Verfahren mit dem Zuverlässigkeitsblockdiagramm und Boole'sche Verfahren

Techniques d'analyse pour la sûreté de fonctionnement - Bloc-diagramme de fiabilité et méthodes booléennes

La présente Norme internationale décrit les procédures de modélisation de la sûreté de fonctionnement d'un système et l'utilisation du modèle pour calculer la fiabilité et la disponibilité. La technique de modélisation BDF est destinée à être appliquée principalement aux systèmes sans réparation et où l'ordre d'apparition des défaillances n'a pas d'importance. Pour les systèmes où l'ordre des défaillances est à prendre en compte, ou lorsque des réparations sont effectuées, d'autres techniques de modélisation, telle que l'analyse de Markov conviennent mieux.

Foreword
The text of document 56/1071/FDIS, future edition 2 of IEC 61078, prepared by IEC TC 56,
Dependability, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 61078 on 2006-03-01.
This European Standard supersedes EN 61078:1993.
The major change with respect to EN 61078:1993 is that an additional clause on Boolean disjointing
methods (Annex B) has been added.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2006-12-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-03-01
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 61078:2006 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following note has to be added for the standard indicated:
IEC 60812 NOTE Harmonized as EN 60812:2006 (not modified).
