MaxInsTx: A Best-Effort Failure Recovery Approach for Artifact-Centric Business Processes
Process instances may overlap and interweave with each other. This significantly complicates the failure recovery issue. Most of existing mechanis- msassumeaone-to-onerelationshipbetweenprocessinstances,whichwillcauseunnecessaryrecoveryinsuchcontext.Artifact-centricbusinessprocess models give equal consideration on both data and control flow of activities, thus facilit- ate addressing this issue. In this paper, we propose a best-effort failure recovery approach MaxInsTx: a transactional artifact-centric business process model with complex cardinality relationships and correlationsconsidered; a recovery mechanism to resolve the impact of the failed process on concurrent processes meanwhile protect maximal instances involved in failures from failure impact.
