Workflow process mining based on Rough Petri Net

The workflow mining technology had become a hot research field among computer application. This paper proposes a mining algorithm based on Rough Petri Net to discovery workflow process witch integrates the features of rough set theory and Petri net. Firstly, the rough Petri Net is described. Secondly, the mining algorithm based on Petri Net is proposed. Then the algorithm of workflow mining based on rough Petri Net is given. At last, Experimental results prove that the algorithm is effective.
