Urban, Regional and National Planning (UNRENAP): Environmental Aspects contains the proceedings of a Workshop on Urban, Regional and National Planning held in Kyoto, Japan, on August 5-6, 1977 under the auspices of the International Federation of Automatic Control. The workshop provided an opportunity to address the environmental aspects of urban, regional, and national planning. The discussions are organized around the themes of modeling, evaluation, simulation, and optimization. Comprised of 34 chapters, this book begins by outlining an alternative approach to environmental modeling in which comprehensive models are replaced by a network of simpler models, focused on specific aspects of the reality and sponsored by corresponding decision-making organizations. The reader is then introduced to some socio-economic aspects of health care planning; structural modeling in a class of systems by fuzzy sets theory; and the role of legal measures in the orientation of urban growth. Subsequent chapters deal with the use of Environmental Assessment Scale as a technique for environmental evaluation; computer simulation of economy management systems; and optimal control models of regional economies. A model for pollution reduction and control is also described. This monograph will be of interest to urban planners and environmental policymakers.
