In this paper we propose an extension to the formalism of timed automata by allowing urgent transitions. A urgent transition is a transition which must be taken within a fixed time interval from its enabling time. We give a set of rules formally describing the behaviour of urgent transitions and we show that, from a language theoretic point of view, the addition of urgency does not improve the expressive power of timed automata.

Abstract

In this paper we propose an extension to the formalism of timed automata by allowing urgent transitions. A urgent transition is a transition which must be taken within a fixed time interval from its enabling time. We give a set of rules formally describing the behaviour of urgent transitions and we show that, from a language theoretic point of view, the addition of urgency does not improve the expressive power of timed automata. However, from a specification point of view, the use of urgent transitions is crucial, especially in modular specification of systems.
