A deadlock prevention policy for a class of Petri nets S3 PR was proposed. A liveness-enforcing Petri net supervisor could be obtained by adding monitors to the plant net model. The approach could generate a correct supervisor with more permissive behavior than the existing methods in Ezpeleta and Li and Zhou, where the same class of Petri nets were dealt with. The obtained additional monitors and related arcs were shown and the net supervisor produced was live with 12656 reachable states.
