Abstract: Based on the fuzzy set theory and the expand principle, using
fuzzy number as the boundary condition of fault tree analysis, a
new method of analyzing fuzzy fault probability of the top event
is developed. Fuzzy importance analysis of the basic event is
proposed as well. A practical example is given. This method is a
new way to solve the obscure problems of fault tree analysis and
has great value in engineering practice.
Key words: Fuzzy
