Refinement operation of workflow nets is provided in this paper for modeling and analyzing integrated workflow. Structure, dynamic properties and behavior expression of refined workflow net are also discussed. These works proves that refinement operation with step-by-step refinement of transitions could realize hierarchical modeling of workflow as well as composite modeling of workflow integration Furthermore, the refinement operation can reduce complexity of model analysis. In fact the reliable refined nets satisfy soundness, and dynamic behavior of refined Petri nets was consistent with of original nets and subnets. Therefore the properties analysis and verification of refined workflow nets can be realized by properties of subnets using refinement operation. Moreover, the research results are successfully applied to designing, modeling and verification of layered workflows and their integration in Shanghai Traffic Information Service Application Grid (STISAG)
