Systematic Refinement of Performance Models for Concurrent Component-Based Systems

Model-driven performance prediction methods require detailed design models to evaluate the performance of software systems during early development stages. However, the complexity of detailed prediction models and the semantic gap between modelled performance concerns and functional concerns prevents many developers to address performance. As a solution to this problem, systematic model refinements, called completions, hide low-level details from developers. Completions automatically integrate performance-relevant details into component-based architectures using model-to-model transformations. In such scenarios, conflicts between different completions are likely. Therefore, the application order of completions must be determined unambiguously in order to reduce such conflicts.
