Abstract: For
general reliability analysis with fuzzy failure and safety state, line
sampling method is presented to calculate general failure probability.
Integral region of the general failure probability is scattered
according to the value of performance function. In the scattered
integral region, the membership func-tion values of the performance
function to the fuzzy failure region keep constant approximately, then
line sampling method is employed to obtain the general failure
probability. The con-cept and the implementation are described step by
step, nu-merical and engineering examples illustrate the rationality and
feasibility of the presented method.
Key words: Line sampling General failure probability
