Symbiotic Simulation
Posted on Wednesday, February 01, 2006 at 5:44 PM by Malcolm
Symbiotic Simulation
Symbiotic simulation is an emergent technology proposed by the Parallel and Distributed Simulation working group at the 2002 Dagstuhl seminar on Grand Challenges for Modelling and Simulation (Fujimoto et al., 2002). Es-sentially, a symbiotic simulation system consists of a simu-lation model interacting with the physical system in a mu-tually beneficial way. The simulation system benefits from the continuous supply of the latest data and the automatic validation of its simulation outputs, whereas the physical system benefits from optimized performance obtained from the analysis of simulation experiments. A symbiotic inte-gration of the real-time physical system and the corre-sponding decision support module will enable prompt re-sponse to be carried out to handle abrupt changes in the physical system. The figure below shows a generic structure of a symbiotic simulation system.
