Time consistency adjustment algorithm of time Petri Net

Time Petri Net is an effective approach to modeling workflow. But existing modeling methods do not consider dynamic adjustment method for time consistency. This paper proposes two adjustment algorithms, CTAA for time consistency and ICTTA for time inconsistency. CTAA can improve the workflow efficiency and ICTAA can make the Petri Net capture the time consistency. We also propose a method to evaluate the time performance of Petri Net generated by CTAA based on granular computing. Finally, we give an instance to show the effectiveness of the proposed algorithms.
