Systems Approach: Some General Comments

The "systems approach" is finding wide application in a large variety of situations. This paper discusses the essential property of this approach: that of seeking to optimize the overall system functions in accordance with specified objectives, and of achieving the best compatibility among its parts. Systems engineering constitutes one of the major components of the systems approach. An important step in the systems engineering methodology involves either mathematical or physical modelling Difficulties encountered in the formulation of the models are discussed.
