Hans-Jürgen Zimmermann was Chairman of the Department for Operations Research at the Aachen Institute of Technology and is from 1967 till 1999 Scientific Director of ELITE (European Laboratory for Intelligent Techniques Engineering).
He received his Bachelor in Engineering from Darmstadt Institute of Technology, his Masters in Engineering and his Ph.D. in Mathematical Economics and Business Administration from the Technical University of Berlin. After having held various positions in industry, he was Professor at the University of Illinois and has been teaching at various universities in India, Europe and the USA. He received his first Honorary Doctorate from the Free University of Brussels and his second Honorary Doctorate from the Abo Akademi University, Finland. In 1985 he received the EURO Gold Medal, the highest distinction in Operations Research in Europe, the K.S. Fu Certificate of Appreciation, the highest distinction of the "North American Fuzzy Information Processing Society" and in 1993 the Moisil Prize and Gold Medal.In 1997 he received the Kaufmann Prize:Gold Medal for Excellence in Uncertainty Research in Management, and in 1998 the EURO Pass in Gold. In 1999 he received "European Pioneers Award" for pioneering research from EuSFLAT th "Special Certificate of Merit "from IFSA and became Fellow of IFSA and the first Honouray Member of GOR, the german Operations Research Society.
He has published more than 240 papers in the areas of Operations Research, Decision Theory, and Fuzzy Set Theory and 30 books in English and German in similar areas. He was Editor-in-Chief of the International Journal for Fuzzy Sets and Systems and Editor of the European Journal for Operational Research, from 1978 till 1999 and is Editor of the book series International Series in Intelligent Technologies, and Editor or Co-Editor of another 12 International Journals.
He has been President of the German Operations Research Society, the European Associations of Operational Research Societies, IFSA (International Fuzzy Systems Association), the German Industrial Engineering Society, and EEMA (European Engineering and Management Associations). He has also been Vice President of IFORS (International Federation of Operational Research Societies) and some other professional associations. Dr. Zimmermann has been organizer or chairman of numerous national and international conferences.
He has been actively pursuing research in fuzzy set theory and its applications since 1972. His current research interests include fuzzy mathematical programming, fuzzy control, fuzzy expert systems, fuzzy data analysis, and their application to various areas, such as, strategic planning, managerial decision making, concurrent engineering, etc. He is supervising a number of industrial projects, in which these methods are applied to industrial problems. He is also responsible for two software houses engaged in operations research and intelligent software solutions.
