【 摘 要 】

D-S evidence theory can bring incorrect results when there is inconsistent and conflicting among the evidences, in order to solve this problem, a method based on reliability and falsity is proposed in the paper. Firstly, the reliability of each evidence in the system identification framework is calculated according to the Lance distance, then, falsity of evidence is adopted to measure the degree of conflict between different evidences, combining reliability and falsity determines corrected coefficient of evidences, and basic probability assignment is reconfigured, finally, modified basic probability assignment are fused by D-S combination rule. The experimental results show that the proposed method can effectively handle the problem of conflict evidence, meanwhile the method is applied to the tire pressure monitoring system, which can identify the target well and has high reliability.
