With the development of web services related technologies, the enterprise business systems can be encapsulated through web services. The service oriented architecture can be adopted for the enterprise business processes. Specific interfaces are introduced between the web services of different enterprises for data exchanging to achieve the cross-enterprise systems integration. Different enterprises can be organized into virtual enterprise through web services to share resources and achieve win-win.

This paper introduces an adaptive model of virtual enterprise based on dynamic composition of web services (DCWS-VE). A service execution plan will be dynamically built to aim at the target of the virtual enterprise through the composition of web services. The development and deployment of web services is separated to support the dynamically deploying and binding of the web service at run time. The members in the virtual enterprise will be located through the dynamic web service discovery based on DAML+OIL logic reasoning, and selected through the dynamic web services negotiation with multi- steps protocol to organize the virtual enterprise at run time. Electronic contract is adopted in the organizing process of virtual enterprise to achieve the stable running.
