Abstract :
Self-healing in workflow is becoming prominent because of the increasing software complexity. In order to support robust workflow execution, in this paper, we propose a self-healing mechanism to replace the faulty service dynamically. It is based on our previous research work -workflow execution system (WES). The OWLS2BPEL Mapper in WES is further enhanced to embed the self-healing mechanism into BPEL workflow by exploiting Semantic Web service technology. In order to realize service substitution, business rules is utilized to model the essential business logic behind the service interface (local business rules) and the service selection policy of a composite service (global business rules) in a domain-dependent and semantic-rich manner. A concrete scenario in PC manufacturing collaborative virtual enterprise is presented to test our self-healing capable workflow execution system.
