Abstract

In this paper, we study the relations that exist between Dempster-Shafer Theory and one of its extensions named DSmT. In particular we show, by using propositional logic, that DSmT can be reformulated in the classical framework of Dempster-Shafer theory and that any combination rule defined in the DSmT framework corresponds to a rule in the classical framework. The interest of DSmT rather concerns the compacity of expression it manipulates.
