Titel: Self-Healing Service-Based Processes
Kurzfassung: This talk introduces a self-healing approach to handle exceptions in service-based processes and to repair the faulty activities with a model-based approach. During execution, whenever an exception arises, diagnosis of the failure is performed and repair plans are generated by taking into account information about the process execution, constraints posed by the process structure, dependencies among data, and available repair actions. However, in practice complete specifications of process activities are not available. Therefore, diagnosis and repair methods for partial behavior models are of great importance. We show that if the assumption of complete behavioral models is lifted, basic diagnosis and repair problems reside on the second level of the Polynomial Hierarchy. The talk also describes the main features of the prototype developed to validate the proposed repair and diagnosis approach for composed Web services. The self-healing architecture for repair handling and the experimental results are illustrated.
