ANDREWS, J.D....[et al.], 2005. Assessing system reliability through binary decision diagrams using bayesian techniques. IN: Proceedings of the 16th Advances in Reliability Technology Symposium (ARTS), Loughborough University, UK, April 2005, pp 65-74
Binary Decision Diagrams (BDDs) have been shown to be efficient for the numerical
evaluation of the reliability of complex systems. They achieve exact results where
Fault Tree Analysis could generally produce only bounds. In this paper the approach
to systems evaluation using a Bayesian method in conjunction with BDDs is explored.
The advantages of the approach are discussed with respect to both efficiency and the
ability to deal with dependency within the system in a natural manner. As an
illustration a simple pump configuration is considered which features a dependency.
The results demonstrate both the flexibility of the approach and the ease of dealing
with the additional complexity of dependency.
