Combined use of finite-state machines and petri nets for modelling communicating processes
Achille Pattavina, Sebastiano Trigila · Electronics Letters · 1984
In order to model and verify systems of concurrent processes (such as those involved in communication protocols), finite-state machines and Petri nets can be used as local and global models, respectively. The problem of composing a set of communicating finite-state machines into a single global Petri net is considered in the letter with special attention to the case of more than two processes.
