Aiming to the aggregation of hybrid preference information, five kinds of hybrid preference information are
unified by intuitionistic fuzzy. Then expert weight is computed by evidence conflict degree based on conflict coefficient and
Jousselme distance. Finally, Demsper combination rule is used to combine the mass functions modified. An illustrative
example shows that the proposed method can preserve the alternative’s preference order, and the result of evidence
aggregation is in accordance with the majority of experts because of mass function modified by expert’s weight, which
has high availability.
