When upper probabilities are possibility measures

Résumé

A characteristic property is given for a pair of upper and lower probabilities (induced by lower probability bounds on a finite set of events) to coincide with possibility and necessity measures. Approximations of upper probabilities by possibility measures are discussed. The problem of combining possibility distributions viewed as upper probabilities is investigated, and the basic fuzzy set intersections are justified in this framework.
