The fuzzy set of type 2 can be characterized by a fuzzy membership function the grade (or fuzzy grade) of which is a fuzzy set in the unit interval [0, 1] rather than a point in [0, 1]. This paper investigates the algebraic structures of fuzzy grades under the operations of join ...
Some Properties of Fuzzy Sets of Type-2Some Properties of Fuzzy Sets of Type-2doi:10.1016/S0019-9958(76)80011-3The concept of fuzzy sets of type 2 has been defined by L. A. Zadeh as an extension of ordinary fuzzy sets. The fuzzy set of type 2 can be characterized by a fuzzy membe...

Subsethood is the degree of containment of one fuzzy set in another, usually expressed as a value in the unit interval. We extend Kosko's definition of subsethood to Type-n fuzzy sets, for which subsethood is a Type-(n-l) fuzzy set on the unit interval. We then show how to compute...
1) O-type fuzzy set O型模糊集1. The degrce of fuzziness on O-type fuzzy sets and D-type fuzzy sets are introduced. 并讨论了D型隶属函数与聚类的关系,对D型模糊集和O型模糊集分别定义了模糊度且研究了相应的性质。2) o-fuzzy-number O型模糊数 1. In order to realize the expression of ...

Overview of Type-2 Fuzzy logic systems. International Journal of Fuzzy System Applications (IJFSA) 2(4): 1-28. [Impact Factor: 1.65]. Fuzzy set theory has been proposed as a means for modeling the vagueness in complex systems. Fuzzy systems usually employ type-1 fuzzy sets, representing u...
