Type-Reduction of the Discretised Interval Type-2 Fuzzy Set : Approaching the Continuous Case through Progressively Finer Discretisation

The defuzzification of a type-2 fuzzy set is a two stage process consisting of firstly type-reduction, and secondly defuzzification of the resultant type-1 set. This paper considers three approaches to discrete interval type-reduction: 1. The exhaustive method which produces the TypeReduced Set, 2. the Greenfield-Chiclana Collapsing Defuzzifier which gives… CONTINUE READING
