Abstract: To meet the requirement of simplifying and improving simulation process of special industrial fields, a simulation supporting system was designed based on special modelbase. The design idea of supporting system framework was proposed by adopted reusing model technology. With the background of cold rolling process control system, the extract principle of standard simulation flow, the construction method of special field modelbase, and the mechanism of simulation support system were discussed. An application example was provided to prove the feasibility and practicability of the framework of supporting system presented in this paper.
