Research on business process modeling and business process service based on Web service

This paper introduces the major process modeling methods and presents a new process modeling method based on Web service. The method enables business processes to be released and called as Web services and provides support for access service function. In the course of process execution, if an external service is required, the corresponding access service node will be added during process modeling. Traditionally, it is difficult for operators to take part in workflow system by Web service. To solve the problem, the author proposes a message management system in which the service provider and the requester communicate with each other via messages to realize manual participation.
