Improving the behaviour of supervisor under blocking

Sometimes, under control of a supervisor a discrete event system couldconstitute a conservative solution in this case relaxing the blocking becomes an inevitablefact to improve the performance. Meanwhile the balance between blocking andachievement has to be preserved. So the strings that drive the system to blocking and alsothe strings causing achievement have to be investigated in a numerical manner. For thispurpose in this study a new performance measure is introduced. The elements of theperformance measure depend on numeric values obtained from strings that correspond toblocking and success so the proposed formulation captures the fundamental trade-offmotivated by the classical optimization approach. Then a new algorithm that explores thebest result according to this performance measure is introduced.
