Abstract: This paper provides a set of intelligent simulation techniques of structure state, which mainly combines intelligent technique of information processing, mix programming, scientific visualization technique, and computer dynamic simulation and emulative technique, visualization interface based on XML technique, soft component technique and engineering database, etc, this method fully integrates advanced computer science and technology with structure analysis and optimization. Then, intelligent visualization is proposed and researched. Especially, two improved gray models (GRBF static prediction model and metabolic GM(1,1) dynamic prediction model ) that can well visualize small sample data simulation are proposed. Finally, fundamental intelligent simulation frame of structure state is built.
