Network Collaborative Workflow Modeling And Implementation Of Technology Research In The Work Environment

With the development of information technology and network technology, networked manufacturing is becoming a new paradigm for manufacturing industry. As a powerful tool of process management, workflow management is one of the key technologies to support the implementation of collaborative work. It can shorten product development time, improve the quality of the product, reduce the cost and improve the quality of the service, thereby enhance the competition capability of enterprises.In this paper, the architecture of workflow management system is given to meet the requirements of the application in the networked collaborative work system, which establishes the strong foundation for the further research. The workflow infrastructure based on Web Service is proposed to support the architecture in the cooperation environment of HAD (heterogeneous, autonomous, distributed).Workflow Modeling is the base for implementing the workflow management. It is analyzed under the collaborative work system from the view of organization model, resource model, information model, and process model. Based on this, a graphical model description is proposed, which accord with the standard of the process definition established by workflow management coalition and use XML technology and database technology in data management. The study of model building rule and model interchange rule ensure the realization of the process integration in collaborative work environment.Workflow runtime control is to guarantee operations effectively and run efficiently in the workflow management. A framework of the Enactment is put forward. Based on the framework, the function of the components and the relation between them is discussed in detail. Workflow runtime control rule is formulized in ECA rules and its application in database is researched to realize the control logic. In the end, the interoperation between workflow engine and the environment is researched.According to the methods and theories researched above, a workflow management module in prototyping system is developed. In the end of the paper, the realization method and the application of the system are introduced.
