This book contains a selection of revised papers and state-of-the-art overviews on current trends and future perspectives of fuzzy systems. A major aim is to address theoretical as well as application-oriented issues and to contribute to the foundation of concepts, methods, and tools in this field. The book is written by researchers who attended the workshop "Fuzzy Systems ´93 - Management of Uncertain Information" (Braunschweig, Germany, October 21-22, 1993), organized by the German Society of Computer Science (GI), the German Computer Science Academy (DIA), and the University of Braunschweig.Dieses Buch enthält ausgewählte und auf neuesten Stand gebrachte Fachaufsätze und "State of the Art"-Übersichtsartikel in englischer Sprache. Sie geben einen Überblick über aktuelle Trends sowie Zukunftsperspektiven der Fuzzy-Systeme. Besonderer Wert wird darauf gelegt, daß das Buch in einem ausgewogenen Verhältnis von Theorie und Praxis zur Fundierung von Konzepten, Methoden und Werkzeugen beiträgt. Hervorgegangen ist das Werk aus einem von der Gesellschaft für Informatik (GI), der Deutschen Informatik Akademie (DIA) und der TU Braunschweig gemeinsam veranstalteten GI-Workshop "Fuzzy-Systeme ´93 - Management unsicherer Informationen" (Braunschweig, 21.-22.10.1993). Die Aufsätze wurden überarbeitet und um Überblicksartikel ergänzt, geschrieben von H. J. Zimmermann, H. Hellendorn, D. Nauck, C. Freksa, S. Gottwald und K. D. Meyer-Gramann.
