Industrial dynamics without DYNAMO

This paper presents an alternative implementation technique for systems models of the type described in J.W. Forrester's book Industrial Dynamics. Methods for converting Industrial Dynamics models written in the specialized language DYNAMO into equivalent State-variable models are presented, and a simple Fortran IV computer program for analyzing the translated models is discussed. A significant advantage of this new technique is that it allows the use of any small computer with a Fortran capability as a research tool for systems dynamics studies, making the field of Industrial Dynamics available to a wider range of institutions than is presently the case.
