AG-IVE: An agent based solution to constructing interactive simulation systems. An Interactive Simulation System (ISS) allows a user to interactively explore simulation results and modify the parameters of the simulation at run-time. An ISS is commonly implemented as a distributed system. Integrating distributed modules into one system requires certain control components to be added in each module. When interaction scenarios are complicated, these control components often become large and complex, and are often limited in their reusability. To make the integration more flexible and the solution more reusable, we isolated these control components out of the system’s modules and implemented them as an agent framework. In this paper we will describe the architecture of this agent framework, and discuss how they flexibly integrate distributed modules and provide interaction support.
