Abstract: The increasing amount of data collected from dynamic systems in real time poses a fundamental question to the modeling and simulation community: how to integrate real-time data with simulation to enable real-time prediction and analysis for a dynamic system under study? Answering this question requires a systematic examination of the relationship between data and simulation, as well as new ways of making (real-time) data and simulation work together. This talk will present Dynamic Data Driven Simulation (DDDS) as a new simulation paradigm that combines real-time data with simulation models for studying dynamic systems. A set of DDDS activities will be described, including dynamic state estimation, online model calibration, external input forecasting, and real-time simulation-based prediction/analysis. Their roles in DDDS and their relationships with other modeling and simulation activities will be discussed. The talk will also introduce data assimilation as an enabling technique for DDDS and shows how data assimilation can be carried out for discrete simulations.
