The Reversible Released Form of Petri Nets and Its Applications to Soundness of Workflow Nets
Ferucio Laurenţiu Ţiplea, Ioana Leahu · IEEE Transactions on Systems Man and Cybernetics Systems · 2015
The reversible released form (RRF) of Petri nets is introduced as an extension of the released form. This new form introduces undo transitions in order to reverse the effect of some of the transitions of the original Petri net. It is shown that the RRF preserves the soundness property of workflow (WF) nets: a WF net is sound if and only if its RRF is sound too. Then, various properties of the RRF of circuit-based Petri nets are investigated, and complexity results of the soundness property of circuit-based WF nets are derived.
