A Top-down Modeling Mechanism in Multi-domain Modeling and Simulation Platform

The bottom-up modeling approach based on the traditional drag-and-drop modeling method employed in most of current multi-domain modeling platforms can not support the forward design.A top-down modeling mechanism based on empty components is presented to model multi-level abstract expression of complicated products easily.The interface of empty component and update process of models are discussed respectively.A simulation instance adopting the proposed mechanism to model complicated multi-domain problem is given.
