%0 Journal Article %A Montero De Juan, Francisco Javier %A Tejada Cazorla, Juan Antonio %T A necessary and sufficient condition for the existence of Orlovsky's choice set %D 1988 %@ 0165-0114 %U https://hdl.handle.net/20.500.14352/57459 %X In a previous paper [2], the authors proved that a property of ‘acyclity’ in fuzzy preference relations was anecessary and sufficientcondition for the existence of unfuzzy nondominated alternatives when such aset of alternatives is finite. In this paper, a general property of ‘foundation’ is proved to be anecessary and sufficientcondition, without requiring finiteness on the set of alternatives. Both concepts are based on classical results in crisp binary relations. %~
