We study the model-checking problem for weighted timed automata and the weighted CTL logic by the bisimulation approach. Weighted timed automata are timed automata extended with co...
Abstract. In a seminal paper, McMillan proposed a technique for constructing a finite complete prefix of the unfolding of bounded (i.e., finitestate) Petri nets, which can be used ...
Abstract. Time Petri nets have proved their interest in modeling realtime concurrent systems. Their usual semantics is defined in term of firing sequences, which can be coded in a ...
This paper considers distributed systems, defined as a collection of components interacting through interfaces. Components, interfaces and distributed systems are modeled as Petri...
Of special interest in formal verification are safety properties, which assert that the system always stays within some allowed region. Each safety property can be associated with...
