International futures (IFs): History and status

The INTERNATIONAL FUTURES (IFS) global model was developed for education and theory building. There are two versions: a smaller one developed specifically for microcomputers and a larger one initially developed for mainframes but now being revised for micros. The model represents global demographic, agricultural, energy, and economic systems. Incorporation of domestic governmental processes and interstate behavior is foreseen. Keywords world modeling, global modeling, international futures, simulation, modeling.
