New Coloured Reductions for Software Validation
Résumé
Structural model abstraction is a powerful technique for reducing the complexity of a state based enumeration analysis. We present in this paper accurate reductions for high-level Petri nets based on new ordinary Petri nets reductions. These reductions involve only structural and algebraical conditions. They preserve the liveness of the net and any LTL formula that does not observe the reduced transitions of the net. The mixed use of structural and algebraical conditions significantly enlarges their application area. Furthermore the specification of the transformation is parametric with respect to the cardinalities of coloured domains.
