Abstract: Structure theory deals with connections between the behaviour of a system and the structure of the corresponding net. Structure theory is well developed for free choice nets. In this paper it is shown that with a notion of simulation close to bisimulation, it is impossible to simulate all confusion free nets with free choice nets.
Keywords: free choice simulation (of) net(s); free choice net; bisimulation; confusion free.
