A new combination rule based on conflict redistribution was proposed to resolve the problem of DSmT. In order to further improve the DSmT performance in dealing with uncertain, highly conflicting and imprecise information, this paper researched the method to develop DSmT on the intuitionistic fuzzy sets, an intuitionistic fuzzy belief assignment mapping was defined to replace traditional belief assignment function, and the combination rule based on the new mapping was discussed in this paper. Numerical examples demonstrate the effectiveness of the proposed method.
