Discussion of theory framework for Simulation Science and Technology discipline

Propelled by application, simulation science and technology (SST) developed continuously, establishing relatively self-governed theory framework which include the similarity theory of simulation model and research object, simulation modeling theory, simulation system theory and simulation application theory. This paper brought forward that the similarity theory of simulation model and research object mainly studies the similar relationship and the similar degree, simulation modeling theory mainly studies the theories and methods abstracting the research object and mapping to simulation model, simulation system theory studies the theories and technologies of model experiment, simulation application theory studies various theory and technology of simulation application directed by simulation target.
