QRML: A Component Language and Toolset for Quality and Resource Management
vanden Berg, F.
Cyber-physical systems (CPS) are complex, heterogeneous, and dynamic systems, spanning hardware and software components ranging from edge devices to cloud platforms. CPS need to satisfy many rigorous constraints, e.g., with respect to deadlines, safety, and quality, yielding a large configuration space where only a limited number of configurations meet the constraints and only a fraction are optimal regarding certain qualities. Finding the optimal configurations is hard, especially during runtime operation. We present QRML, the Quality and Resource Management domain-specific Language, and an accompanying toolset. QRML enables specifying heterogeneous hardware/software systems and their composition and configurations conveniently, automated reasoning about them, and generating implementation artifacts like quality and resource monitoring templates. A QRML model consists of a hierarchy of components. Component specifications express constraints and requirements, that may serve multiobjective quality and resource optimization and exploration purposes. The QRML toolset offers language support, visualizations, documentation generation, template-code generation, and constraint-solving support.
