Abstract: To analyze system functions and data in Petri net model, an incidence-matrix-based method was presented. As an example, a typical enterprise information system was modeled by Petri net, as well as the function structure and dataflow of the system were described. Based on the incidence matrix, properties of system functions and data accuracy were analyzed. Their relationships were also discussed. A clustering algorithm based on incidence matrix was presented according to nearest-neighborhood-first principle, and the algorithm realized automatic classification of the system. Research result showed that the new method described data and enterprise processes effectively, it could also promote system development by using unified Petri net model.
