Similarity Measure between Generalized Fuzzy Numbers Using Quadratic-Mean Operator

This presents a novel similarity measure that is based on the quadratic-mean operator to solve similarity measurement problems that involve generalized fuzzy numbers. Some properties of the proposed similarity measure are demonstrated, and 36 sets of generalized fuzzy numbers are adopted to compare the proposed method with existing similarity measurement methods. The results of the comparison show that the proposed similarity measure is better than existing methods.
