This process w as divided into three steps, w orkf low log preprocessing, process activity control graph reconfiguration and generation of act ivity trans fer condit ions. Among them, process activity control graph reconfiguration w as the core step. By modeling the ac tivity execution as an interval, the relationship between tw o activities execut ion durations could be categorized into three kinds, as disjoint, overlapped and contained, and a heuristic algorithm was designed based on this relationship to search activitiessequential relationships contained in w orkflow log, so that the quality management process model
