At the border of fuzzy systems and chaos theory a new field emerges: the largely unexplored arena of nonlinear systems with fuzzy-type uncertainty. The first book devoted to this new field, this text explains the principles and applications of the dynamics of fuzzy and neuro-fuzzy systems. It identifies the primary trends and offers many examples of applications that illustrate relevant concepts. Demo software for generating and analyzing chaotic fuzziness is available on the Internet. The promise held by this new discipline along with the unique and comprehensive nature of this book make it an invaluable, state-of-the-art resource for advanced researchers and students.
