      public BAGT(BDD<T> bdd, org.apache.commons.collections15.Transformer<T,ReliabilityFunction> transformer)
      Returns a BAGT calculator for a specific system with its BDD and ReliabilityFunction Transformer.
      Parameters:
      bdd - The BDD representing the system structure function
      transformer - The Transformer used to get the ReliabilityFunction of variables present in the BDD

    • calculate

      public Map<T,Double> calculate(BAGT.Variant variant)
      Calculates one of the BAGT importance measure variants. Note: This function might have infinite run times for some variants using non coherent systems. This is due to the MomentEvaluator having an infinite run time for the restricted reliability functions in those cases.
      Parameters:
      variant - The variant of BAGT to be calculated.
      Returns:
      results Map of components and their respective BAGT importance.
