Abstract
Fuzzy preference relations are considered and the concept of “fuzzy acyclity” is defined in order to measure their rationality. Such a concept is applied to study the properties of social welfare function in a fuzzy environment. In particular, the existence of non-irrational aggregation rules is assured, in such a way that they can be used as a group decision aid.Keywords
