According to the principle of "Separation of Concerns", by investigating the similarity between multi-view software process modeling and object Petri nets, this paper proposes the MOPN-SP-net model which is a multi-view software process model based on object Petri nets and enhances the reusability of software process model. During process modeling, MOPN-SP-net is a multi-dimensional Petri net, which is difficult to analyze directly. So, this paper provides a translation rule from an object Petri net to an equivalent traditional flat Petri net. The translation preserves the soundness property. According to the translation rule, the soundness property of the MOPN-SP-net can be indirectly analyzed by its translated flat net.
