From Requirements to Architectures for Better Adaptive Software Systems

Abstract. The growing interest in developing adaptive systems has led to numerous proposals for approaches aimed at supporting their develop-ment. Some approaches define adaptation mechanisms in terms of archi-tectural design, consisting of concepts such as components, connectors and states. Other approaches are requirements-based, thus concerned with goals, tasks, contexts and preferences as concepts in terms of which adaptation is defined. By considering only a problem- or a solution-oriented view, such proposals are limited in specifying adaptive behavior. In this paper we present ongoing work on supporting the design and run-time execution of adaptive software systems both at a requirements and architectural level, as wells as its challenges, ranging from architectural derivation from requirements to refined adaptation control mechanisms
