A novel combination method is proposed to handle conflict evidence. A method to obtain evidence’s support
degree is proposed by calculating the focal element-distance, and then a“referenced evidence”is obtained by averaging all
evidences according to support degree. The referenced evidence is used for uncertainty verification and model modification
of the original evidences, and Dempster-Shafer rule is applied to evidence combination. Numerical experiments show that
the combination result of the proposed method is rational.
