You might try reading this paper on the subject:

"Uncertainty representation and propagation in quantified risk assessments
using fuzzy sets"
J Quelch & T T Cameron
Journal of Loss Prevention in the Process Industries, 1994, Vol 7, No 6, PP

It compares calculations done using Monte Carlo simulations and using fuzzy
