Modeling of Device Collaboration Process Based on Petri Net

In the area of device collaboration system, there are a large number of devices which needed to be collaborated with other devices, and the collaboration process is complex. It is significative to reduce the complexity of modeling a device collaboration process. In this paper, a device collaboration process model is proposed, which includes four basic structures. By use of device collaboration net, the modeling rules of the basic structures are proposed. By using a collaborative process modeling example, the modeling rules are described.
