Application Research Of Dynamic Workflow Technology Based On The Role

With the widely use of computer technology, network technology and e-commerce technology, the workflow technology has been developed quickly. Due to the business process reengineering, a higher demand was put forward to meet how to make the process to adapt with the dynamic change. So this thesis is focusing on the role of a dynamic workflow technology from the point of role.Firstly it analyzed the inadequacy of workflow model in dealing with role based on the current models and gave out a role-based workflow model. By analyzing the dynamic characteristics of workflow model, it studied the dynamic workflow which is based on role deeply. Then it analyzed the dynamic modeling technology based on role and analyzed the dynamic accessing and controlling methods based on role's states independently. Furthermore it designed an algorithm supporting dynamic evolution of model. Finally an application was given out which is a dynamic approval process based on role.It was pointed out that it's easier to describe the dynamic characteristics of workflow by using role, which provides a great help to study the dynamic workflow. At the same time, the application which was studied in this thesis will give a whole example about how to design and construct the dynamic workflow management system based on role.
