Epidemic spread model based on cellular automata

Based on the theory of complexity adaptive system,we build a cellular automata model to simulate the complex process of epidemic spread.Based on this model,we simulate the spread process of SARS successively.Then several factors,such as move of people,whether being treated in time,which have great effects on the propagation of epidemic are analyzed,and whose effects on epidemic are studied.Some suggestion to deal with this kind of problem is given finally.
