Dynamic failure recovery of generated workflows

An important research area in the workflow management domain is the adaptation of workflows to unexpected events or failures at runtime. In this paper we present a concept for dynamic and automated workflow re-planning that allows to recover from such failures. To handle the complex dynamic situation of a partially executed workflow, we propose a multi-step procedure that includes the termination of failed activities, the sound suspension of the workflow, the generation of a new process definition, and the adequate process resumption. An important aspect of the presented re-planning procedure is that all steps including the generation of a new process definition are fully automated.
