Abstract: Virtual enterprise modeling (VEM) is regarded as the basic support for studies on virtual enterprises. A UML-based VEM(VEM-UML) method， is put forward . This modeling method leads the key modeling concepts of VEM into UML by extending the new metaclasses and stereotypes. The extension together with the inherent properties of UML makes the VEM-UML an efficient virtual enterprise modeling language. A virtual enterprise established for designing and manufacturing helicopters is modeled to prove the effectivity of VEM-UML on modeling virtual enterprises. Compared with the traditional enterprise modeling methods， the advantages of the VEM-UML are highlighted on modeling virtual enterprises. Finally， the mapping mechanism from the VEM modeling concepts to the UML modeling elements is presented to provide VEM an abstract syntax and semantics.
