On System Dynamics.

Abstract

THEOREM, Production functions, *Growth modelsThe paper presents an exegesis of Forrester's system dynamics using conventional mathematical concepts and briefly reviews its advantages and disadvantages. First, Solow's well-known economic growth model is translated into Forrester's language. Next, the mathematical structure of a general class of Forrester type models is spelled out. Three constructive suggestions are made for augmenting the methodology. These suggestions involve improved numerical integration methods, numerical control theory techniques and a parameter saving, flexible class of smooth functions for representing nonlinear relationships. Then the best known of the Forrester-type models, World 2, is briefly discussed from the point of view developed here. (Author)
