Role Reconstitution of Business Process Based on Multilevel Log Data Analysis

Internet cooperative office environment promotes the development and application of workflow technology, achieving an official pattern of cross-regional and cross-sectoral. The cooperative office deals with the issue of spatial distance constraints in the interaction of business activities. However, the original staff cooperative mode in the existing office environment reflects the problems of cost of large and low efficiency and other issues. Fortunately, massive business workflow logs and database logs provide a possible way for understanding the running of the process. How to use the log data of the process and find the unnecessary cooperation in the original process model, as well as optimize the process model are the urgent problems to be solved at present. In this paper, we do the analysis of multilevel logs from database logs to workflow logs. Through the mining of the workflow log data and the exploring of the correspondence between the activities and roles in the business process, a structure identifying method is proposed. This method reconstitutes the correspondence between activities and roles based on the role permission redistribution and roles merging corresponding to the excessively decentralized subtasks. As a result, some unnecessary cooperative time can be reduced by removing the unnecessary roles and the running efficiency of the process can be improved to a greater extent.
