Decidable and Undecidable Problems in Schedulability Analysis Using Timed Automata
Abstract. We study schedulability problems of timed systems with nonuniformly recurring computation tasks. Assume a set of real time tasks whose best and worst execution times, and...

Task automata: Schedulability, decidability and undecidability
We present a model, task automata, for real time systems with non-uniformly recurring computation tasks. It is an extended version of timed automata with asynchronous processes th...

Undecidability of Universality for Timed Automata with Minimal Resources
Timed automata were introduced by Alur and Dill in the early 1990s and have since become the most prominent modelling formalism for real-time systems. A fundamental limit to the al...

Universality and Language Inclusion for Open and Closed Timed Automata
The algorithmic analysis of timed automata is fundamentally limited by the undecidability of the universality problem. For this reason and others, there has been considerable inter...

Zone-Based Universality Analysis for Single-Clock Timed Automata
Abstract. During the last years, timed automata have become a popular model for describing the behaviour of real-time systems. In particular, there has been much research on proble...
