It is shown how it can be obtained through fuzzy relations, which are at least reflexive. We study the corresponding multi-modal systems depending on the properties satisfied by the approximate relation. Finally, we show some equivalences between possibilistic logical consequences and global/local logical consequences in the multi-modal systems. | Descripción: | This is a revised and extended version of the paper "Approximate-based Multi-Modal Systems and Possibilistic Logic: A comparative study" in proc. of ESTYLF'96, Publi.
