Cyber–physical system (CPS) is a complex system that contains multiple components working cooperatively. According to its characteristics, we propose an object-oriented generalized stochastic Petri ...

Timed Petri nets (TPNs) are useful for performance evaluation of discrete event systems due to their mathematical formalism. This paper focuses on their use to model the preemption of emergency ...

Cluster tools are automated production cells which are largely used for semiconductor manufacturing. They consist of several processing modules (PMs) and a transportation robot. Since cluster tools ...

Medical students are called to acquire competence to manage disease in its dynamic evolution over time, learning to analyze how clinical conditions evolve in a patient's history and how each condition ...

We present a way to lift up the Tower complexity lower bound of the reachability problem for Petri nets to match the Ackermannian upper bound closing a long standing open problem. We also prove that ...
