Adaptive Software & Services

The ever increasing complexity, size, dynamicity, and distribution of modern software systems and service-based systems requires novel, systematic approaches to assure their quality during run-time.

The research group 'Adaptive Software and Services' investigates into novel techniques, methods and tools that can be employed to identify failures of software systems during their operation, as well as to predict imminent failures in order to proactively trigger an evolution or adaptation of the software systems or the business processes they support. The techniques include novel run-time quality assurance approaches such as online testing ("active monitoring") and run-time verification.

Research Topics

• Online failure prediction for proactive adaptation, employing run-time quality assurance techniques (including run-time verification and online testing)
• Multi-aspect and decentralized adaptation of Future Internet Applications (including federated and human-in-the loop adaptation)
• Quality assurance for variability-intensive systems (jointly with VIS)
