Flexible Workflow Management for Virtual Enterprise Through Web Service

Members in a virtual enterprise and the services provided by them change frequently.By adding Web service requests to activity specifications defined in the workflow process model and assigning the corresponding contents and constraints through templates for different kinds of Web services and Web service requests‚the dynamic Web service binding and invocation between a service request and an optimal service provider is realized at the time when an instance of activity is in execution.Higher flexibility and self-adaptability of workflow management are achieved because the normal business process of virtual enterprise is not affected by changing the partners involved.
