'... Professor Zimmermann's treatise is a major contribution to the literature of fuzzy sets and decision analysis. ' L.A. Zadeh from the Foreword 'I highly recommend this text for students, both novice and advanced in theory and applications, academics and industrial researchers. Of course, this book is a must for all academic libraries. Indeed, Professor Zimmermann, who as a researcher, author, editor and organizer of international meetings has contributed so much for the cause of the fuzzy sets and systems and the fuzzy community, deserves our compliments.' Madan M. Gupta, Intelligent Systems Research Laboratory, University of Saskatchewan, Canada '...the extensive bibliography, as well as the excellent chapters on applications are of wide interest. Those teaching courses in fuzzy set theory, especially in a more practical rather than abstract context, would do well to consider this textbook. Zimmermann has compiled a collection of information that is useful, clearly presented, and with the latest revision, reflects much current research.' International Journal of General Systems, 21 (1992) 'The up-to-date content as well as the author's style and method of presentation make the book to be one of the best presentations of the whole field of fuzziness and will maintain its role as one of the preferred introductions into that topic.' European Journal of Operations Research
