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 ...
متن کاملRecursive 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...
متن کاملA Kleene-Schützenberger Theorem for Weighted Timed Automata
During the last years, weighted timed automata (WTA) have received much interest in the real-time community. Weighted timed automata form an extension of timed automata and allow us to assign weights (costs) to both locations and edges. This model, introduced by Alur et al. (2001) and Behrmann et al. (2001), permits the treatment of continuous consumption of resources and has led to much resear...
متن کاملFrom Timed Automata to Logic - and Back
One of the most successful techniques for automatic verification is that of model checking. For finite automata there exist since long extremely efficient model–checking algorithms, and in the last few years these algorithms have been made applicable to the verification of real–time automata using the region–techniques of Alur and Dill. In this paper, we continue this transfer of existing techn...
متن کاملModel Checking Real-Time Systems
This chapter surveys timed automata as a formalism for model checking real-time systems. We begin with introducing the model, as an extension of finite-state automata with real-valued variables for measuring time. We then present the main model-checking results in this framework, and give a hint about some recent extensions (namely weighted timed automata and timed games).
متن کاملDeterministic Timed AFA: A New Class of Timed Alternating Finite Automata
Timed Alternating Finite Automata (TAFA), a natural generalization of Timed Finite Automata (TFA), are synchronous and powerful models for real-time computations. They become an effective and expressive model for developing embedded systems with real-time constraint computations which are required in many applications. We introduce Deterministic Timed Alternating Finite Automata (DTAFA), a new ...
