The Binary Decision Diagram method has been formulated over the last decade. It is the latest methodology developed to overcome the deficiencies of the common fault tree analysis technique. Its advantages include increased efficiency in determining the qualitative characteristics of a failure...

This paper is concerned with ETA (event-tree analysis)where the branch point event causes are defined using faulttrees. Attention is on the nontrivial situation where there are dependenciesamongst the branch point events. The dependenciesare due to component-failures in more than one of the...
