Workflow interoperability across enterprises boundaries presents a significant challenge recently. Process-view provides a promising way to cross-organizational workflows design. A multi-agent system combined with Petri net based process-view approach is proposed to facilitate cross-organizational workflows management. Within this multi-agent system, a Petri net algebra model and a character string mapping algorithm are proposed to automate the mapping from a Petri net workflow model to a process-view workflow model; the synchronization points are added to integrated process-view workflow models to coordinate the execution of cross-organizational workflow instances.
