A New Combination Rule of Evidence Theory on Multi-Source Information Fusion

(1)On traditional evidence theory, conflict coefficient K is generally used to measure the conflict of evidence, which only consider the non-inclusive among evidences, and without considering the differences among the evidences. To solve this problem, this paper first proposed a modified measure method of evidence conflict, which measured evidence conflict through conflict coefficient K and the pignistic distance between evidences, this way not only reflects the non-inclusive among evidences, but also reflects the differences among the evidences; and then, this paper gives the process of combination rule of the new method; finally, typical examples showed the new method is effective and adaptability.
