Counterexamples for property violations have a number of important applications like
supporting the debugging of erroneous systems and verifying large systems via …

The computation of counterexamples for probabilistic model checking has been an area of
active research over the past years. In spite of the achieved theoretical results in this field …

Probabilistic model checking is a technique employed for verifying the correctness of
computer systems that exhibit probabilistic behaviour. A related technique is controller …

This paper presents several symbolic counterexample generation algorithms for discrete-
time Markov chains (DTMCs) violating a PCTL formula. A counterexample is (a symbolic …

We consider the problem of safety analysis of probabilistic hybrid systems, which capture
discrete, continuous and probabilistic behaviors. We present a novel counterexample …

We report on the modeling and formal analysis of reliability requirements in the context of an
Airport Surveillance Radar system using SysML and probabilistic model checking. The …

Stochastic hybrid systems consist of software-controlled physical processes, where
uncertainties manifest due to either disturbance in the environment in which the physical …

Bei der Entwicklung sicherheits-kritischer Systeme, ist die Bewertung von verschiedenen
Entwurfsalternativen von großer Bedeutung. Eine solche Bewertung ist in den frühen …

Discrete event systems (DES) are an important subclass of systems (in systems theory).
They have been used, particularly in industry, to analyze and model a wide variety of real …

Software is becoming the main innovation factor in many domains. Every more functionality
is implemented in software running on relatively generic hardware. For this the notion of …
