An aggregating method for group evaluation based on the degree of consensus

In this paper, based on using triangular fuzzy numbers to represent evaluation opinions, a new method is proposed for aggregating individual fuzzy options into a group fuzzy consensus opinion. After factors affecting group opinion have been analyzed, the weight of each expert's opinion is output. The aggregating process and method are discussed in detail. The characteristics and properties of this method are also introduced and proved. An example given at the end of paper shows the effectiveness of this method.
