Object-oriented Petri nets, their simulation, and analysis

The article presents the so-called object-oriented Petri nets (OOPNs) combining advantages of Petri nets and object-orientation. OOPNs are described mostly informally, but the key concepts of their formal definition are also included. Furthermore, the computer-aided tool called PNtalk which supports editing and simulating OOPNs is briefly mentioned, too. Finally, problems accompanying formal analysis of OOPNs, stemming from the high dynamism of models based on them, are discussed.
