Abstract: Dezert-Smaradache Theory retains conflicting focal element in the combined result, which benefits the combination ability for conflict evidence, meanwhile, it results in the accumulation of conflicting information, and makes the composite reliability of main focal element reduce illogically. A new combination rule based on conflict redistribution is 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 researches the method to develop DSmT on the intuitionistic fuzzy sets. An intuitionistic fuzzy belief assignment mapping is defined to replace traditional belief assignment function, and the combination rule based on the new mapping is discussed in this paper. Numerical examples demonstrate the effectiveness of the proposed method.
