چکیده

The paper presents a method of abstraction for timed systems. To extract an abstract model of a timed system we propose to use static analysis, namely a technique called path compression. The idea behind the path compression consists in identifying a path (or a set of paths) on which a process executes a sequence of transitions that do not influence a property being verified, and replacing this path with a single transition. The method is property driven since it depends on a formula in question. The abstraction is exact with respect to all the properties expressible in the temporal logic CTL −X.

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 ...

Scheduling with timed automata

In this work we present timed automata as a natural tool for posing and solving scheduling problems. We show how efficient shortest path algorithms for timed automata can find optimal schedules for the classical job-shop problem. We then extend these results to synthesize adaptive scheduling strategies for problems with uncertainty in task durations.

On Presburger Liveness of Discrete Timed Automata

Using an automata-theoretic approach, we investigate the decidability of liveness properties (called Presburger liveness properties) for timed automata when Presburger formulas on configurations are allowed. While the general problem of checking a temporal logic such as TPTL augmented with Presburger clock constraints is undecidable, we show that there are various classes of Presburger liveness...

Optimal Paths in Weighted Timed Automata

We consider an optimal-reachability problem for a timed automaton with respect to a linear cost function which results in a weighted timed automaton. Our solution to this optimization problem consists of reducing it to a (parametric) shortest-path problem for a finite directed graph. The directed graph we construct is a refinement of the region automaton due to Alur and Dill. We present an expo...

Job-Shop Scheduling Using Timed Automata

In this paper we show how the classical job shop scheduling problem can be modeled as a special class of acyclic timed automata Finding an optimal schedule corresponds then to nding a shortest in terms of elapsed time path in the timed automaton This representa tion provides new techniques for solving the optimization problem and more importantly it allows to model naturally more complex dynami...
