Discovery of role-based organization structure model in BPMS

The existing organizational structure modeling methods are difficult to model team structure. In business process management system (BPMS) there are a large number of event logs recording the performers and corresponding activities. Usually if the role of performers is similar, they can be classified as a same team. This paper design a role-based organization structure model discovery method based on event logs from BPMS. This method analyzes activities type and activities frequency of different performers in the event logs in order to judge their role similarity. Firstly, a PA (performer-activity) diagram is designed to describe the relations between different performers and activities; secondly, the role relation discovering rules are designed; At last, the measures of the role similarity among performers are designed based on which an organization structure can be modeled.
