Models have been shown to be useful during virtually all stages of the software lifecycle.
They can be reverse engineered from existing artifacts, or created as part of a system's …

Modern automotive systems with adaptive control features require rigorous analysis to
guarantee correct operation. We report our experience in modeling the automotive case …

Traditionally, practitioners use formal methods pre-dominately for one half of the quality-
assurance process: verification (do we build the software right?). The other half-validation …

Validating requirements for safety-critical systems with user interactions often involves
techniques like animation, trace replay, and LTL model checking. However, animation and …

This paper introduces an Event-b formal model of the adaptive exterior light system for cars,
a case study proposed in the context of the ABZ2020 conference. The system describes the …

Traces are used to show whether a model complies with the intended behavior. A modeler
can use trace checking to ensure the preservation of the model behavior during the …

In this thesis we present an approach to apply formal analysis methods in order to improve
the quality of requirements. The approach enables the application of formal analysis …

Writing formal specifications often requires users to abstract from the original problem.
Especially when verification techniques such as model checking are used. Without applying …

Especially in industrial applications of formal modeling, validation is as important as
verification. Thus, it is important to integrate the stakeholders' and the domain experts' …

At the ABZ2020 Conference, the case study track proposed to model an Adaptive Exterior
Light System and a Speed Control System: the former controls different exterior lights of a …
