Knowledge-based architectural adaptation management for self-adaptive systems

Self-adaptive systems continually evaluate and modify their own behavior to meet changing demands. An important element in the construction of architecture-based self-adaptive software is the specification of adaptation policy: this extended abstract presents an overview of work towards basing such specification on architecture-centric knowledge-based policies. This approach leverages techniques from the artificial intelligence field to explicitly represent adaptation policy at the architectural level, providing for strong decoupling between policy specification and architectural compositions, and supports dynamic runtime policy evolution promoting reuse potential and runtime flexibility.
