The author presents the results of his own experience in using systems ideas, assembles a coherent account of their development and application, and examines the relationship of particular systems methodologies and concepts to the nature of the problems encountered. It emphasizes problem solving and surveys the types of modeling languages appropriate to various parts of a problem spectrum in systems design. Stresses the development of a modeling language and its applications, particularly to the (soft) less well-defined/ill-structured problems, which often require a non-mathematical language based on the concept of a human activity system. Specific problems in actual situations are discussed, including the design of a services complex, services systems and an operational system, as are the analysis of business information and role analysis. There is also a study of management control that includes discussion of concepts that illustrate and emphasize the distinction made between management and process control. Features exercises that will help develop skills in picture building and problem solving.
BRIAN WILSON has a background in nuclear power engineering and control system design. In 1966 he became a founding member of the Department of Systems Engineering at the University of Lancaster, where he pursued the application of control principles to management problem solving. There he was involved in the development and use of Human Activity Systems and 'verbs in the imperative' in place of mathematics as the modelling language for the intellectual processes involved and maintained particular interest in the application of SSM to information and organisation-based analysis. This research was published in Systems: Concepts, methodologies and Applications by John Wiley Sons.
