Modeling distributed business processes of virtual enterprises based on the object-oriented approach and Petri nets

Based on the object-oriented approach and Interval Timed Coloured Petri nets (ITCPNs), we study the modeling of distributed business processes in virtual enterprises. We model each member enterprise in a virtual enterprise as an object, and define both the internal model of the member enterprise object and the interaction model among the member enterprise objects based on ITCPNs. These two kinds of models are two views of the system and when combined, a complete model for the whole business process of the virtual enterprise is achieved.
