Abstract: Connotation of flexible workflow was analyzed. Its implementation approaches were categorized into dynamic selection, dynamic refinement, dynamic deviation, and dynamic change, each of which was studied in-depth. Then, their strength, weakness, and application domains were compared and analyzed. Furthermore, the rigid execution mechanism, the insufficient information in the workflow model, and incomplete functions were identified as the main shortcomings of contemporary approaches. Finally, the methodology of data-centered workflow modeling and operation, flexible distributed workflow, and integration of flexibility and supportability were recognized as the future research trends from the perspectives of theory, application domain, and practice, respectively.

Key words: flexible workflow, dynamic selection, dynamic refinement, dynamic deviation, dynamic change, modeling
