Power sets, implications and set inclusions revisited - Retrospect and prospect: A review of bandler and Kohout's paper and a survey of 30 years of subsequent developments

Abstract

It is an interesting story to look at the development of new concepts in fuzzy set theory. One looks at the motivation, the first formulation and the subsequent development. In our case study we look at one of the early papers that interrelates the concept of fuzzy set inclusion, power set and many-valued implication operators, namely the paper of Bandler and Kohout [4]. This is followed by discussion of the subsequent related work by the fuzzy community. © 2009 Springer-Verlag Berlin Heidelberg.
