Abstract:

Combination of intervalvalued belief structures can describe and deal with uncertainty problems effectively. In order to solve the problems of fusion failure existed in current methods, its reasons are analyzed. The new method extracts the characteristics of evidence source and modifies the evidence according to the characteristics. The evidence is modified according to the characteristics extracted from the evidence, and two kinds of optimization models are proposed to combine the intervalvalued belief structure. The experiment results show that the proposed method is convergent and robustness. And reasonable result can be obtained in the face of combination of intervalvalued belief structure with confliction.
