摘要：The similarity co.putations for fuzzy membership function pairs were carried *** number related knowledge was introduced,and co.ventional similarity was co.pared with distance based similarity *** usefulness of the proposed similarity measure was *** results show that the proposed similarity measure co.ld be applied to ordinary fuzzy membership functions,though it was not easy to *** co.ventional results on the calculation of similarity for fuzzy membership pair,fuzzy membership-crisp pair and crisp-crisp pair were carried *** proposed distance based similarity measure represented rational performance with the heuristic point of ***,troublesome in fuzzy number based similarity measure for abnormal universe of disco.rse case was ***,the similarity measure co.putation for various membership function pairs was discussed with other co.ventional results.
