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.engjournal articlehttp://www.sciencedirect.com/science/article/pii/0165011488900103http://www.sciencedirect.comrestricted access519.22Decision-makingRelationsNondominated alternativesEstadística matemática (Matemáticas)1209 Estadística
