In this paper, we present a revised similarity measure based on
Chen-and-Chen's similarity measure for fuzzy risk analysis. The revised
similarity measure uses the corrected formulae to calculate the centre of
gravity points, therefore it is more  effective than the Chen-and-Chen's
method. The revised similarity measure can overcome the drawbacks of the
existing methods. We have also proposed a new similarity measure between type-2
fuzzy numbers and a method for handling fuzzy risk analysis problem.
