Despite the proliferation and ever-increasing need for distributed processing and parallelism in computer and communication systems, their operational behaviour has been poorly understood. This is due to the extreme complexity found in cooperative processing in modern computer systems, and the complicated communication protocols for handling a variety of traffic in information network systems. In order to cope with these developments, mathematical modelling has become more and more sophisticated, and tailored to individual problems. However, it is fair to say that the performance characteristics of today's (and future) systems cannot be fully analyzed by the techniques currently available. This book is a result of the international seminar designed to promote progress in the development of techniques for resolving the performance issues of such complex systems.

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.
