ON STRATEGIES OF CYBERNETIC MODEL‐BUILDING

Abstract

Starting from the ordinary (i.e., not model‐theoretic) model concept, the basic notions of the model‐reality relationship are discussed. In particular, the functional and behavioural equivalence is studied. It is argued that although analytically fertile, the distinction between functional and behavioural equivalence overlooks problems of crucial methodological importance. From a methodological stand‐point the knowledge hierarchy of B. Zeigler seems promising. However, Zeigler's approach contains some important ontological commitments which should be given due attention in the process of model building and model validation. Som remarks of model building in economics are used as illustrations for Zeigler's method and the limitations contained therein.
