Orthopartitions and possibility distributions

Orthopartitions are particular sets of orthopairs generalizing the notion of standard partitions in presence of uncertainty, and describing situations where the membership class of some elements of an initial universe is not precisely known.This work aims to bridge orthopartitions with possibility theory. Therefore, our principal contribution here consists of identifying orthopartitions with a special class of Boolean possibility distributions. (c) 2022 Elsevier B.V. All rights reserved.
