Abstract: Current workflow management systems still lack support for dynamic workflow, which is a major requirement for nextgeneration workflow systems. In fact, workflow system can’t confirm all the processes, and the relationship among processes is not invariable. To confirm the dynamic characteristic, the system must have the ability of dynamic change. In order to solve this problem, based on others’ studies about dynamic workflow, this paper introduces the characteristics and kinds of the dynamic workflow, discusses the theory and implement of dynamic change in dynamic workflow. Furthermore, it designs a case to introduce the dynamic revision of the workflow process model.

Key words: workflow, dynamic workflow, dynamic changes, dynamic modification
