虚拟样机, 功能需求本体, 功能模型, 资源发现

In design process of virtual prototyping of complex products,it has already become the most urgent problem to be solved that discovery methods of resources cannot integrate with functional model of complex products.An effective and feasible approach to resource discovery based on function requirement semantics was proposed herein.The functional model and the function requirement ontology was first built,which provided an unified manner to describe the function requirements semantically.Furthermore,virtual prototyping model ontology were defined,and the method of resource discovery based on function requirement semantics was designed.Finally,the system implementation architecture was built up.
