2、can rapidly collect the advantages of these enterprises, and has turned out to be an evolving direction of future corporation formation. It can catch market opportunity fast, fulfill customers needs in time, gather enter

3、prise resources, push technique innovation, and can reduce trade expense and risk. But members of virtual enterprises are separate and the formation of them are incompact, which makes the procedure of planning and contro

4、l in them hard, and increases the risk of the management in the virtual enterprise. With respect to such characteristics in the operation of virtual enterprises, this paper has investigated the relevant theories and tec

5、hnologies of systems for the planning and control of collaboration in virtual enterprises. Discussion has been made on the key points and difficulties in the implementation of such a planning and control system in a virt

6、ual enterprise. This, in together with the analysis on its application environment and system requirements, has led to the proposal of a Web Services based Collaborative Planning and Control System (WS-CPCS), including i

7、ts main functional modules such as the communicate platform, the plan design tool, and the execution control system. Base on the research above, the methods for plan decomposition, task distribution and execution control

8、 have been studied and designed with the application of some key technologies needed, such as XML, Web Services, Agent and workflow management. In accordance with the methodology of hierarchical software system design, t

9、he plan design tool among this proposed framework has been designed, which has four layers including the application layer, the communication layer, the service layer and the data layer. A detailed design and implementat

10、ion plan has been given with the employment of such technologies as Web Services, XML and Agent. The plan execution and control module has been designed with the application of technologies based on workflow management a
