Abstract: Aiming at the conflict problem among evidences in the process of information fusion, one synthetic rule of evidence based on Pignistic probability distance is presented. Evidence reliability is constructed by using the Pignistic probability, and then the body of evidence is altered by using the evidence reliability to improve the synthetic rule. Evidences are fused by employing the improved synthetic rule. Results of numerical examples show that the fusion results obtained through the improved synthetic rule are reasonable and effective. Compared with some other methods, it has good characters in applicability, reliability, and faster processing speed.
