RESUMO
In this work we propose a mechanism for failure detection, group management and service replication, providing fault tolerance for workflow management systems. Workflow management systems require specific replication features, since such systems deal with non-deterministic operations and update their s internal state without any external calls. As a case study we use an industrial automation system and analyze the needed modifications to use the proposed mechanism and evaluate the impact of the mechanism in the system s performance.
