Performance Analysis of Probabilistic Timed Automata Using Digital Clocks
Probabilistic timed automata, a variant of timed automata extended with discrete probability distributions, is a specification formalism suitable for describing both nondeterminis...

Stochastic Games for Verification of Probabilistic Timed Automata
Probabilistic timed automata (PTAs) are used for formal modelling and verification of systems with probabilistic, nondeterministic and real-time behaviour. For non-probabilistic ti...

Towards formal security analysis of GTRBAC using timed automata
An access control system is often viewed as a state transition system. Given a set of access control policies, a general safety requirement in such a system is to determine whethe...

Probabilistic Timed Behavior Trees
The Behavior Tree notation has been developed as a method for systematically and traceably capturing user requirements. In this paper we extend the notation with probabilistic beha...

Model checking based analysis of end-to-end latency in embedded, real-time systems with clock drifts
End-to-end latency of messages is an important design parameter that needs to be within specified bounds for the correct functioning of distributed real-time control systems. In t...
