中文摘要：

针对当前多领域仿真平台建模机制采用拖放式建模、不支持产品正向设计的问题,提出基于空部件的自顶向下建模机制.该机制融合自底向上建模方式,以方便建立复杂多领域层次化模型,同时阐述了空部件的接口设计以及自底向上的模型更新机制.最后结合实例说明了采用该机制建立复杂多领域模型的过程.

英文摘要：

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.
