A New Similarity Measure ot Generalized Fuzzy Numbers

The shortcomings of several existing methods of similarity measure are pointed out after analyzing their principles. By introducing Hausdroff distance in pattern recognition field, each generalized fuzzy number is viewed as an image sample,and then a new formula of similarity measure is constructed. Eighteen sets of generalized fuzzy numbers are used to compare the proposed method with the existing similarity measures. The results show that the new similarity measure can overcome the drawbacks of the existing methods.
