We present a new attempt to build up an axiomatic foundation for defuzzification theory using the theory of groups and the theory of partially ordered sets, and in particular, the theory of GALOIS connections.enUniversität DortmundReihe Computational Intelligence ; 31defuzzificationfunctional, bijective transformationGALOIS connectiongroup, partially ordered set004report
