Abstract: In modern organizations, business processes are variable and flexible. So the workflow should have the ability to cope with the uncertain factors. The dynamic hierarchy refinement Petri-net-based is one of the methods that can handle the uncertain factors. At build-time with this method, the determining factors compose the basic transition. The uncertain factors are encapsulated to the non-basic transition. Thereby, determining factors and uncertain factors are both taken into consideration at build-time. Besides the thought of software component is introduced into the process modeling; the flexible process is encapsulated to component the reusability and maintainability of the process can be improved. Finally through an example, the author recounts the modeling process of dynamic workflow with hierarchy refinement Petri-net- based approach, verifies the soundness as well.
