A Gateway-Centered Workflow Rollback-Points Ancestry Model for Sustainable Workflow Enactments

摘要

In enacting a workflow process that is made up of stepwise activities and their temporal orderings, it is very important to control and trace each instance's execution as well as to keep it sustainable. In particular, the sustainability implies that the underlying system should be able to not only provide an error-detection functionality on its running exceptions but also to furnish a very autonomous recovery mechanism to deal with the detected exceptional and risky situations. As an impeccable technique for realizing the sustainability on workflow process enactment services, this paper tries to formalize a workflow risk-recovery concept to be used in implementing autonomous recovery mechanisms of workflow enactment systems, which is named as gateway-centered rollback-points ancestry model. Conclusively, we believe that the proposed model ought be one of those impeccable trials and pioneering contributions to improve and advance the sustainability in workflow process enactment services.
