Abstract: To satisfy improvement requirements for quality management system, an idea based on workflow-mining technology to support quality management process improvement was presented. This process was divided into three steps, workflow log preprocessing, process activity-control graph reconfiguration and generation of activity transfer conditions. Among them, process activity-control graph reconfiguration was the core step. By modeling the activity execution as an interval, the relationship between two activities execution durations could be categorized into three kinds, as disjoint, overlapped and contained, and a heuristic algorithm was designed based on this relationship to search activities sequential relationships contained in workflow log, so that the quality management process model comprising complicated Plan-Do-Check-Action(PDCA)loop structures was reconstructed. Finally, process improvement of external audit reports treatment was used as a case study to illustrate the proposed approach and its performance.
