Abstract

Traditional simulation methodology supports only changes in models state variables. Some models are better expressed by a combination of both changes in state variables and changes in structure. Dynamic Structure Discrete Event Specification (DSDEVS) is a recently introduced modelling and simulation formalism that provides full support for representing models with time varying structure. The DELTA simulation environment is an implementation of the DSDEVS formalism and provides full support to Structural Simulation. We show the advantages of the Dynamic Structure Cellular Automata describing the model of forest fire spreading and its implementation in the DELTA environment.
