Activity Interaction and Self-Simulating Systems

Two radically new discrete-event simulation modeling technologies are introduced: Activity Interaction (AI), a general approach for modeling system dynamics, and Self-Simulating Systems (S³), where AI models are integrated with information systems to generate correct, current, and credible real-time simulations. The research and development paths taken with these new technologies constitute a meta-experiment on the two fundamental historical approaches to developing new simulation modeling methodology: academic and commercial. Examples in production and service system settings are presented.
