It aims to strengthen re- tions between industry research laboratories and universities, and to create a primary symposium for world scientistsinfuzzy?eldsasfollows: 1) The mathematical theory of fuzzy systems; 2) Fuzzy logic, systems and control; 3) Fuzzy optimization and decision-making; 4) Fuzzy information, identi?cation and clustering; 5) Fuzzy engineering application and soft computing method; etc. This book contains 89 papers, divided into ?ve main parts: In Section I, we have 15 papers on "the mathematical theory of fuzzy systems". In Section II, we have 15 papers on "fuzzy logic, systems and control". In Section III, we have 24 papers on "fuzzy optimization and decisi- making". In Section IV, we have 17 papers on "fuzzy information, identi?cation and clustering". In SectionV, wehave18 papers on"fuzzy engineeringapplicationandsoft computing method". VI Preface In addition to the large number of submissions, we are blessed with the presence of eight renowned keynote speakers and several distinguished p- elists and we shall organize workshops.
