Interval Type-2 Fuzzy Set is the most popular kind of Type-2 Fuzzy Set, its characteristic is that all the secondary membership functions equal to 1. Though Interval Type-2 Fuzzy Sets can reduce the calculation complexity than other Type-2 Fuzzy Sets, it loses much fuzzy information simultaneously. In order to solve this problem we propose a novel theory of Triangle Type-2 Fuzzy Sets, the formulas for union, intersection and complement of Triangle Type-2 Fuzzy Sets are derived and proven in detail. In addition, the relationship and the conversion between Triangle Type-2 Fuzzy Sets and Interval Type-2 Fuzzy Sets are discussed.
Index Terms:
