Application of Haekel’s Thesis to ABSEL Development

In this paper the authors use a model of embryonic development proposed by Haekel to retrace the development of the DECIDE simulation and the development of several key evolutionary stages of ABSEL research. The paper highlights four distinct development stages that the DECIDE simulation went through including; (1)the Demand Functions, Fortran (or BASIC), Mainframe Computer, and Hollerith Card Era, (2) the Administrator’s Summary Sheet Era, (3) Decision Input and Decision Support Systems Era, and the (4) the Artificial Intelligence and Expert Systems Era. Following Haekel’s Thesis the same four evolutionary stages are detailed for ABSEL research.
