Research and implementation of time-based algorithm for mining workflow models

To improve mining accuracy of workflow models,a time-based algorithm was proposed.The execution time of tasks and the following wait time,succession relationships,intersection relationships between tasks were discovered by mining event logs.Setting up the edge matrix between tasks and the task parallel matrix,and finding relationships between edges,a workflow model with time factors was generated.An example was presented to demonstrate the improvements on model accuracy and the description ability of the proposed algorithm.
