Runtime Reconstruction of Simulation Models for Dynamic Structure Systems
In many simulation applications, the target system may change its structure unpredictably. The simulation model should adjust in time, to follow the evolving of the target system. In this paper we put forward a new definition of system to accommodate the dynamic structural change, and classify the structural change of system, include change in components, relationships among components and interaction between system and its environment. Then we propose a distributed framework of simulation model, which supports runtime reconstruction. In this framework, connector components work together to integrate and manage computing components. These elements and their relationship are discussed using π-calculus. We study the weak bi-simulation condition in component replacing, and discuss the consistency of transition of system states. Finally, we point out main problems in modeling and simulation for dynamic structural systems.
