We present automated techniques for the verification and control of partially observable,
probabilistic systems for both discrete and dense models of time. For the discrete-time case …

Fault diagnosis consists in observing behaviours of systems, and in detecting online
whether an error has occurred or not. In the context of discrete event systems this problem …

Controller synthesis addresses the question of how to limit the internal behavior of a given
implementation to meet its specification, regardless of the behavior enforced by the …

A notion of alternating timed automata is proposed. It is shown that such automata with only
one clock have decidable emptiness problem over finite words. This gives a new class of …

In this paper, we study the fault codiagnosis problem for discrete event systems given by
finite automata (FA) and timed systems given by timed automata (TA). We provide a uniform …

We study observation-based strategies for partially-observable Markov decision processes
(POMDP s) with parity objectives. An observation-based strategy relies on partial information …

Timed automata are known not to be complementable or determinizable. Natural questions
are, then, could we check whether a given TA enjoys these properties? These problems are …

In previous work, we have proposed a framework for black-box conformance testing of real-
time systems based on timed automata specifications and two types of tests: analog-clock or …

In this paper we consider the problem of controller synthesis for timed games under
imperfect information. Novel to our approach is the requirements to strategies: they should …

Requirements modelling helps software engineers understand a system's required
behaviour and explore alternative system designs. It also generates a formal software …
