V-DEVS Approach to Simulation Modelling of Urban Dynamics
2010
Arnis Lektauers

In this paper a conceptual framework for integrating of agent-based models with cellular automata, geographic automata systems (GAS) and geographic information systems in the context of modelling and simulation of urban dynamics is proposed. In recent years, a number of research efforts have focused on presenting solutions for modelling and simulation of urban systems using automata-based models allowing a transition from large scale, aggregate spatial representation in a static equilibrium to much finer scale disaggregate forms where dynamic processes are the primary focus of the simulation. The proposed framework uses Visual Discrete Event System Specification (V DEVS) that provides integrated modelling and simulation in a virtual interactive simulation environment, in such way solving the existing problem that multi-agent systems and geographic information systems separately do not provide truly integrative modelling and simulation capabilities. The proposed approach is an extension of DEVS formalism providing a unified system-theoretical basis for integration of simulation modelling and 2D/3D visualization, as well as component-oriented coupling and synchronization of simulation processes, visualization and user interaction. A first analogy between GAS concepts and the V-DEVS formalism has been achieved by using the Shelling’s segregation model as an experimental example, but more experiments need to be done in the future, in order to have a clear idea of what reasonable limits should be imposed on the structure of V-DEVS framework for simulation of urban dynamics.
