Abstract: It is inevitable to introduce changing factors in the process of business system evolution,and how to repair the system model by changing factors in the evolution is of practical significance.The existing model repair mainly focuses on the original reference model and complete log,there are limitations of the original reference model unknown and incomplete log.Therefore,a change detection method based on incomplete logs was proposed,and the event log of Delete,Insert and Move operations were described using activity comparison matrix (behavior contour matrix) in the case of the unknown original model system to find the original event log with the local actual log system change bias field.According to the log deviation domain,the model found in the original log was repaired,and seven algorithms for model repair were proposed.The proposed method was simulated and experimented with ProM tool,and the experimental results showed its validity and correctness.
