The problem of weighting experts in group decision-making is studied. In the decision-making problems, because
the information of object itself is incomplete and uncertainty, and people describe fuzzily in the process of decision-making,
the fuzzy clustering analysis is more suitable for such problems. Therefore, a method for deriving experts’ combination
weights based on judgment matrix and fuzzy kernel cluster analysis is provided, in which the collating vectors of an individual
expert are classified by using fuzzy kernel clustering principle. The experts’ combination weights are determined according
to the result of classification, the judgment matrix’s consistency and the entropy of collating vectors. Finally, a numerical
example shows the feasibility and effectiveness of the proposed method.
