Hierarchical modeling and decomposition for workflow system based on Petri Net

摘要

In this paper, the complex workflow system is viewed as an overarching architecture that is decomposed into the information model, the functional model, the organizational model and the resource model for highlighting different dimension. The compound workflow model-is set up through hierarchical expansion based on those sub-models. An agile manufacturing oriented instance is presented based on the analysis of the key technology of the configuration by means of the Petri nets. For improving the efficiency of the supervision, an approach of the decomposition is demonstrated based on the domain-specified control.
