Research On Workflow System Supporting Dynamic Virtual Enterprise

Workflow technology has been a. new hotspot in the area of Computer Supported Cooperative Work since 1990. It is very important to study the technology in-depth, since it can significantly improve the information degree and operative efficiency of enterprises and government departments, hence make them more competitive.This paper studies technologies on how to realize Workflow System supporting DVE (Dynamic- Virtual Enterprise). The DVE has the characters as cooperative, competitive and learning, and the process of a DVE's form is also the business process's reengineering. How to support business process reengineering(BPR) is a very important application field of WfMS . The WfMS needs to enhance its ability to support this field by new information technology and new ideas.In order to support DVE, we must make it easily express a enterprise's business and improve on the framework of WfMS . Meshwork-node is used to describe the business of a dynamic virtual enterprise, and a new modeling way is brought forward by increasing the elements of meshwork-node in the paper. Following that a distributing structure of WfMS is designed according to the DVE's traits. The WfMS is divided it into many modules, all the models are explained in details. Many difficulties about realizing the system are illuminated in Object-Orient way such as database-designing, workflow-starting , workflow-controlling and duty-managing.According to research, the user-interfaces of Duty-Managing module and Process-Modeling module are designed, and the process of forming and running is analyzed by a DVE based on Supply Chain Management (SCM). The end is the prospect of workflow technology.
