Non equivalence between time Petri nets and time stream Petri nets

Abstract

It had been shown that Merlin's Time Petri Nets are a special case of Time Stream Petri Nets. In this paper, we show that there does not exist a time equivalence between both models. We extend first this result to the non equivalence of Timed Automata and Time Petri Nets and second to the non equivalence of Timed Link Petri Net and Timed Transition Petri Net.
