Research on the architecture of modeling theory in SS&T

Based on analyzing of the common activity and content of modeling, this paper concluded the common essence and rules of modeling in every domain, and established the architecture of modeling theory in Simulation Science & Technology (SS&T), which is formed by general theory of model, model construction theory and modeling methodology. Moreover, the concept of model, the common characteristics and theories about common questions of model were set forth; all existing model construct theories were summed-up and their function and character was differentiated; according to modeling process, most existing modeling methods were regularized with their function and their relations between each other. All these made modeling theory more clearly.
