BEESON, S. and ANDREWS, J.D., 2003. Calculating the failure intensity of a non-coherent fault tree using the BDD technique. IN: Andrews, J.D. (ed.) Proceedings of the 15th Advances in Reliability Technology Symposium (ARTS) , Loughborough, UK, 2003, pp. 249-264.
This paper considers a technique for calculating the unconditional failure intensity of
any given non-coherent fault tree. Conventional Fault Tree Analysis (FTA)
techniques involve the evaluation of lengthy series expansions and approximations are
unavoidable even for moderate sized fault trees. The Binary Decision Diagram (BDD)
technique overcomes some of the shortfalls of conventional FTA techniques enabling
efficient and exact quantitative analysis of both coherent and non-coherent fault trees.
