Domain-specific languages (DSLs) are an important tool for effective system development. They provide concepts that are close to the problem domain and allow analysis as well as generation of full solution implementations. However, this comes at the cost of having to develop a new language for every new domain. To make their development...

Recent results in language engineering simplify the development of tool-supported executable domain-specific modelling languages (xDSMLs), including editing (e.g., completion and error checking) and execution analysis tools (e.g., debugging, monitoring and live modelling). However, such frameworks are currently limited to sequential execution...

The quality of a software system can be measured by the extent to which it possesses a desired combination of quality attributes (QAs). While some QAs are achieved implicitly through the interaction of various functional components of the system, others (e.g., security) can be encapsulated in dedicated software components. These QAs are known...

Context: Domain-Specific Visual Languages (DSVLs) play a crucial role in Model-Driven Engineering (MDE). Most DSVLs already allow the specification of the structure and behavior of systems. However, there is also an increasing need to model, simulate and reason about their non-functional properties. In particular, QoS usage and management...

We address some of the limitations for extending and validating MDE-based implementations of NFP analysis tools by presenting a modular, model-based partial reimplementation of one well-known analysis framework, namely the Palladio Architecture Simulator. We specify the key DSLs from Palladio in the e-Motions system, describing the...

When configuring a software product line, finding a good trade-off between multiple orthogonal quality concerns is a challenging multi-objective optimisation problem. State-of-the-art solutions based on search-based techniques create invalid configurations in intermediate steps, requiring additional repair actions that reduce the efficiency of...
