As a variation of Dempster-Shafer theory (DST) of evidence, the Dezert-Smarandache Theory (DSmT) of plausible and paradoxical reasoning allows to formally combine any kind of information (certain, uncertain, paradoxical). It was developed by Jean Dezert and Florentin Smarandache.
The DSmT is intended to fusion complex data/information fusion problems where conflicts (paradoxes) between sources become large and when the refinement of the frame of discernment is inaccessible because of the vague, relative, and imprecise nature of elements of the frame of discernment. The usefulness of this theory is highly controversial, as it appears to be a special case of DST for which the power set of the frame of discernement serves as the actual frame of discernement.
