ABSTRACT
The classic statement of systems theory occurs in W. Ross Ashby’s, Design For A. Brain. A brief and non-technical description of the objectives of systems analysis would include: the study of a set of interrelated variables, as distinguished from the environment of the set, and of the ways in which this set is maintained under the impact of environmental disturbances. This definition emphasizes the articulation of the system and of its components and the behaviors by means of which it maintains itself over time.
