A rule-based approach for multi-perspective adaptation of service-based systems

A key feature of any business process (BP) implemented as service-based system (SBS) is adherence to compliance. BP workflows are frequently prone to faults or anomalies of various kinds namely, functional, temporal, structural, regulatory or technological updates. If faults are not handled in a timely manner, it may result in violation of service level agreements (SLAs). Therefore it is crucial for any BP to be flexible enough to adapt to changes of various categories. Current adaptation approaches try to adapt from either data (interface) mismatches from service perspective, temporal requirements from business perspective or resource constraints from the infrastructure perspective. We propose an adaptation framework which is capable of recovering from data, control-flow, temporal and infrastructure faults. The prototypical implementation using rule based approach is applied on a laboratory simulation.
