      public ABGT(BDD<T> bdd, org.apache.commons.collections15.Transformer<T,ReliabilityFunction> transformer)
      Returns a ABGT 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(double time)
      Calculates the ABGT importances for all components at the specified time. Uses equation 15 and 23 of [ABGT17] to calculate the importance from the failure and repair CriticalityBDDs of the components.
      Specified by:
      calculate in interface TimeDependentImportanceMeasure<T>
      Parameters:
      time - Time t at which the ABGT importance of all components is calculated. Must be greater than 0, otherwise an IllegalArgumentException is thrown.
      Returns:
      results Map of components and their respective ABGT importance at time t.
