On the ranking of ill-known values in possibility theory

Résumé

This short note improves a result of Roubens and Vincke on possibility graphs, i.e. valued ordering relations defined on a finite set of fuzzy numbers, using possibility theory. Especially, the Ferrers and min-max transitivity property for possibility graphs are obtained as a straightforward consequence of an inference rule in possibilistic logic.
