Abstract: By analyzing the process's definition in workflow modeling, the factors resolved in modeling are polymerized with different model， and the global model of workflow system is considered as the combined model of the information model, function model, organization model and resource model. The logical relationship among these models is explored and the steps of hierarchical modeling are discussed in theory. The detailed approaches for hierarchical modeling are put forward,which is illustrated by an instance of agile manufacturing. For simplified representation of the complex workflow's model, a strategy of decomposition is proposed based on the hierarchical and blocking method and how to make use of this method is demonstrated.
