Abstract
Consider an agent with fuzzy preferences, who has to make exact choices whe n faced with different feasible sets of alternatives. Confining our analysi s to the case of feasible sets with not more than two alternatives, we axio matically characterize two broad classes of decision rules ('ratio rules' a nd 'difference rules') for determining exact choices from these two-element feasible sets on the basis of fuzzy preferences.
