Transformations of Timed Cooperating Automata

Transformations of Timed

The paper pursues the investigation of Timed Cooperating Automata (T CA) by studying transformations which are suggested as means for stepwise TCA construction.

Using Interval Petri Nets and Timed Automata for Diagnosis of Discrete Event Systems (DES)

A discrete event system (DES) is a dynamic system that evolves in accordance with the abrupt occurrence, at possibly unknown irregular intervals, of physical events. Because of the special nature of these systems, different tools are currently used for their analysis, design and modeling. The main focus of this paper is the presentation of a new modeling approach of Discrete Event Systems. The ...

Recursive Timed Automata

We study recursive timed automata that extend timed automata with recursion. Timed automata, as introduced by Alur and Dill, are finite automata accompanied by a finite set of real-valued variables called clocks. Recursive timed automata are finite collections of timed automata extended with special states that correspond to (potentially recursive) invocations of other timed automata from their...

Timed Automata with non-Instantaneous Actions

In this paper we propose a model, timed automata with non-instantaneous actions, which allows representing in a suitable way real-time systems. Timed automata with non-instantaneous actions extend the timed automata model by dropping the assumption that actions are instantaneous: in our model an action can take some time to be completed. We investigate the expressiveness of the new model, compa...
