Updatable timed automata

P Bouyer, C Dufourd, E Fleury, A Petit - Theoretical Computer Science, 2004 - Elsevier
We investigate extensions of Alur and Dill's timed automata, based on the possibility to
update the clocks in a more elaborate way than simply reset them to zero. We call these …

Forward analysis of updatable timed automata

P Bouyer - Formal Methods in System Design, 2004 - Springer
Timed automata are a widely studied model. Its decidability has been proved using the so-
called region automaton construction. This construction provides a correct abstraction for the …

Untameable Timed Automata! Extended Abstract

P Bouyer - Annual Symposium on Theoretical Aspects of …, 2003 - Springer
Timed automata are a widely studied model for real-time systems. Since 8 years, several
tools implement this model and are successfully used to verify real-life examples. In spite of …

Using non-convex approximations for efficient analysis of timed automata

F Herbreteau, D Kini, B Srivathsan… - arXiv preprint arXiv …, 2011 - arxiv.org
The reachability problem for timed automata asks if there exists a path from an initial state to
a target state. The standard solution to this problem involves computing the zone graph of …

Model checking timed safety instrumented systems

J Lahtinen - 2008 - aaltodoc.aalto.fi
Defects in safety-critical software systems can cause large economical and other losses.
Often these systems are far too complex to be tested extensively. In this work a formal …
