A conceptual methodology for conducting faster-than-real-time experiments

Faster-than-real-time simulation concepts are nowadays applied in multidisc iplinary areas. Interaction between the real world and the simulation model is performed in real time, so that information obtained from each system i s used to enhance our knowledge of the other. Even if such capabilities pro ve to be useful for real-time applications, dealing,with the requirements i mposed is only accomplished through extending the traditional simulation me thodology. Since model execution is performed faster than real-world time, experimentation is considered as the most critical phase. A methodological approach towards an experimentation framework for interacting in real time with the actual system is introduced and analyzed in terms of its functiona lity, the activities it incorporates and the restrictions imposed. Realizat ion of this methodological framework is also discussed through a simulation example.
