Investigation of the potential of fuzzy sets and related approaches for treating uncertainties in radionuclide transfer predictions
This paper reviews four aspects of fuzzy sets, namely, the general framework, the role of expert judgement, mathematical and computational aspects, and present applications. Fuzzy-set theory is applied to simplified problems in radionuclide migration, with comparisons between fuzzy and probabilistic approaches, treated both analytically and computationally. A new approach to fuzzy differential equations is presented, and applied to simple ordinary and partial differential equations. It is argued that such fuzzy techniques represent a viable alternative to probabilistic risk assessment, for handling systems subject to uncertainties.
