Properties of Distributed Time Arc Petri Nets.
In, Foundation of Software Technology and Theoretical Computer Science, FST&TCS 2001.
In recent work we started a research on a distributed-timed extension of Petri nets where time parameters are associated with tokens and arcs carry constraints that qualify the age of tokens required for enabling. This formalism enables to model e.g. hardware architectures like GALS. We give a formal definition of process semantics for our model and investigate several properties of local versus global timing: expressiveness, reachability and coverability.
