      Description copied from class: AbstractAggregation
      Imports the data from a specified element
      Overrides:
      importFromXML in class AbstractAggregation

      the master node where the data structure values are anchored

    • aggregateAll

      protected double aggregateAll(Alternative _alternative, ArrayList<Criterion> _criteria, Weighting _weighting)
      Description copied from class: AbstractAggregation
      Delegated method to subclass for doing a full aggregation on the complete set of criteria for a given alternative.
      Specified by:
      aggregateAll in class AbstractAggregation
      Parameters:
      _alternative - the alternative to aggregate for
      _criteria - the list of all criteria
      _weighting - the weighting for the criteria
      Returns:
      the full aggregation value

    • aggregateGroup

      protected double aggregateGroup(Alternative _alternative, CriterionGroup _group, ArrayList<Criterion> _criteria, Weighting _weighting)
      Expression aggregation does not work for groups in general.
      Specified by:
      aggregateGroup in class AbstractAggregation
      Parameters:
      _alternative -
      _group -
      _criteria -

    • aggregateSingle

      protected double aggregateSingle(Alternative _alternative, Criterion _criterion, ArrayList<Criterion> _criteria, Weighting _weighting)
      Description copied from class: AbstractAggregation
      Delegated method to subclass for determining the aggregation value of a single criterion for a given alternative. The aggregation is done in respect to the aggregation of the full set e.g. in respect to the overall maximum.
      Specified by:
      aggregateSingle in class AbstractAggregation
      Parameters:
      _alternative - the alternative to aggregate for
      _criterion - the criterion to determine the aggregation value for
      _criteria - the list of all criteria
      _weighting - the weighting for the criteria
      Returns:
      the single aggregation value

    • fixVariableName

    • getHighestTier

      public int getHighestTier()
      Description copied from class: AbstractAggregation
      Get the highest tier for which tierwise information is available. Weighted sum provides information for any tier, TOPSIS and weighted product only for the lowest tier 0.
      Specified by:
      getHighestTier in class AbstractAggregation
      Returns:
