Paper Abstract

The objective of this study is to present a novel model for simulating the evolution of gradual change systems. The proposed model, named SDCA-state delay cellar automata, extends the traditional cellar automata (CA) to include state delay, variable time step, and state-delay cell evolving to aid prediction making for the gradual systems developments. The model can perform microcosmic changing happens in one time step through changing state-delay time. In this article, the SDCA model used to simulate the forest fire spreading which is a typical gradual changing system under different external conditions. As experiments' result shown, SDCA model can simulate the forest fire spreading and perform gradual changing with time step varied accurately and simply. Finally, it is concluded that the SDCA model is an effective model in simulating the gradual changing systems' propagation.
