A generic symbiotic simulation framework

• A symbiotic or online simulation is defined as one that interacts with the physical system in a mutually beneficial way. The simulation is driven by real time data collected from a physical system under control and needs to meet the real-time requirements of the physical system. In turn, the results from the "what-if experiments performed by the simulator can be used to control the dynamic behaviour of the physical system. Such a simulation tool is for real-time planning and is to foresee and advise on real time problems. It aims to improve performance, to adapt to sudden and unexpected events and to improve aspects of safety and security of the physical system. There are some research efforts, for example, the Dynamic Data-Driven Application Systems (DDDAS) which are currently advocated by the National Science Foundation (NSF) of the United States. However, work in this area is far from complete and many of the research issues are not fully addressed. We see the need for a general framework for symbiotic simulation. In this project, simulators based on the same general framework will be developed using symbiotic simulation techniques and will be used to provide adaptive decision support to manage the resources in several application environments. The objectives of this project are: To develop a generic, agent-based, symbiotic simulation system architecture. To develop mechanisms to support dynamic coupling between the symbiotic simulation system and the physical system. To conduct pilot case studies of the simulation framework. To explore and evaluate the service oriented architecture approach for parallel simulation in the multi-agent symbiotic simulation framework.
