Description:
From the viewpoint of system dynamics the whole structure and functions of a system do not simply equal the algebraic sum of the parts which the system consists of. There universally exist mutual relationships between the transmition and exchange of information, energy and material within the whole system, its parts and its environment. The aim of this paper is to study the organic ties among the three of the whole, parts and environment of a system and the transmition involved under specific conditions. In this paper, the logical relationships between the internal and external parts of the system are described. Two concepts of the transmition matrix and the relationship matrix are presented along with the definitions of the grades of the grades of variables. Their concepts and definitions, combining the theory of the model reference self-compensation, are used to form a new method by which the functions of the structures and relationship between the whole system and its parts can be identified. Some satisfied results have been obtained from testing this new method on the Boom-town Dynamic Model.
