Richards 9The cybernetic concepts of variety, constraint, circularity, and process provide the foundations for a theoretical framework for the design of policy support systems. The theoretical framework consists of a modelling language and a modelling mathematics. An approach to building models for policy support sys- tems is detailed; two case studies that demonstrate the approach are described. The modelling approach focuses on the structure of mental models and the subjec- tivity of knowledge. Consideration is given to ideas immanent in second-order cybernetics, including paradox, self-reference, and autonomy. Central themes of the book are "complexity", "negative reasoning", and "robust" or "value-rich" policy. 9424 pages; 23 tables; 56 illustrations Hardback: ISBN 0-8191-3512-7 $28.75 Paperback:ISBN 0-8191-3513-5 $16.75 9order from: University Press of America 4720 Boston Way Lanham, Maryland 20706 USA
