Modern software systems adapt themselves to changing environments in order to meet
quality-of-service requirements, such as response time limits. The engineering of the …

Abstract Model transformation is one of the key tasks in model-driven engineering and relies
on the efficient matching and modification of graph-based data structures; its sibling graph …

Self-adaptation allows continuously running software systems to operate in changing and
uncertain contexts while meeting their requirements in a broad range of contexts, eg, from …

The graph programming language GP (Graph Programs) 2 and its implementation is the
subject of this thesis. The language allows programmers to write visual graph programs at a …

Empowering end-users to wire Internet of Things (IoT) objects (things and services) together
would allow them to more easily conceive and realize interesting IoT solutions. A challenge …

To tackle the growing complexity of engineered systems, Model-Driven Engineering (MDE)
proposes to promote models to first-class citizens in the development process. Within MDE …

This dissertation thesis presents an approach enabling the modelling and quality-of-service
prediction of event-based systems at the architecture-level. Applying a two-step model …

Many software development, planning, or analysis tasks require an up-to-date software
architecture documentation. However, this documentation is often outdated, unavailable, or …

We present a new form of quantitative safety analysis-safety optimization. This method is a
combination of fault tree analysis (FTA) and mathematical optimization techniques. With the …

Model-driven performance engineering allows software architects to reason on performance
characteristics of a software system in early design phases. In recent years, model-driven …
