The proceedings of the Tenth European Meeting on Cybernetics and Systems Research, held in Vienna, Austria, from April 17-20, 1990, cover a wide range of topics in cybernetics and systems research. The book is edited by Robert Trappl and the Austrian Society for Cybernetic Studies. It includes contributions from various fields such as general systems methodology, fuzzy sets, design and systems, humanity, architecture, and conceptualization, cybernetics in biology and medicine, socio-economic systems, artificial intelligence, and the impacts of artificial intelligence. The book is divided into several sections, each focusing on different aspects of cybernetics and systems research. The first section includes general systems methodology, with contributions on learning automata theory, self-organizing networks, and conformation versus novelty in reconstructability analysis. The second section focuses on fuzzy sets, with topics such as operational fuzzy set theory, knowledge-based systems, and fuzzy decision making. The third section discusses design and systems, with contributions on design principles, design apprenticeship, and evolutionary guidance systems. The fourth section explores humanity, architecture, and conceptualization, with topics such as the two-fold price of intellect, simulation of depth psychological processes, and cybernetics, autopoiesis, and the definition of life. The fifth section covers cybernetics in biology and medicine, with contributions on membrane potential recovery, ion channel correlations, and medical cybernetics. The sixth section discusses socio-economic systems, with topics such as economic forecasting, policy modeling, and the role of feedback in macroeconomic policy. The seventh section focuses on artificial intelligence, with contributions on consultation frameworks, knowledge representation, and parallel distributed processing. The eighth section explores the impacts of artificial intelligence, with topics such as AI for social citizenship and expert games. The final section includes a panel on organizational cybernetics, national development planning, and large-scale social experiments. The book concludes with an author index and a subject index.The proceedings of the Tenth European Meeting on Cybernetics and Systems Research, held in Vienna, Austria, from April 17-20, 1990, cover a wide range of topics in cybernetics and systems research.
