Cybernetic model of the design process

Computer-aided design can be seen as a process in which a careful integration of tje specific characteristics of man and machine is taking place. This integration may lead to better design results, quantitatively and /or qualitatively. The realization of this integration in c.a.d. systems necessitates a renewed and profound analysis of the design process. A model of the design process is developed against the background of the evolution of this process. To this end, cybernetics is used as a meta-language. The development of c.a.d. systems based on this model is discussed.
