Modelling Ambient Systems with Coloured Petri Nets

This paper is concerned with the formal modelling of Ambient Systems, focussing on the issues that emerge in their modelling using coloured Petri nets. A new class of coloured Petri nets, called Ambient Petri Nets (APNs), is introduced. Furthermore, a related step-modelling approach and its rationale are described. After that, the modularity and compositionality of the new class of Petri nets are discussed, and a method of composing APNs is introduced.
