Abstract:

Aiming at paradoxes generated in combination of highly conflict evidences, a method based on trustworthy factors to modify the evidence source is proposed. Firstly, the consistency among multi-source evidences is checked, and the conflict evidence is recognized and modified. Then, the reliability and uncertainty of evidences are analyzed, and the definition of trustworthy factors is given based on them. Finally, trustworthy factors are used to modify the evidences. Comparative experiments show that the proposed method can deal with the combination problem of conflic evidences effectively, and the results are reasonable.
