      public static String getNodeTag()
      Get the tag of the master node of a data structure.
      Returns:
      the master nodes tag

    • importFromXML

      public void importFromXML(org.jdom2.Element _element)
      Imports the data from a specified element
      Parameters:
      _element -

    • exportToXML

      public org.jdom2.Element exportToXML()
      Exports the data to a XML node.
      Returns:
      the element

    • getWeightedNormalized

      protected double getWeightedNormalized(Alternative _alternative, Criterion _criterion, Weighting _weighting)
      For convenience shortcut to get the weighted normalized value of a criterion for a given alternative.
      Parameters:
      _alternative - the alternative to aggregate for
      _criterion - the criterion to determine the aggregation value for
      _weighting - the weighting for the criteria
      Returns:
      the weighted normalized value

    • doAggregateAll

      public double doAggregateAll(Alternative _alternative, ArrayList<Criterion> _criteria, Weighting _weighting)
      Do a full aggregation on the complete set of criteria for a given alternative.
      Parameters:
      _alternative - the alternative to aggregate for
      _criteria - the list of all criteria
      _weighting - the weighting for the criteria
      Returns:
      the full aggregation value

    • doAggregateGroup

      public double doAggregateGroup(Alternative _alternative, CriterionGroup _group, ArrayList<Criterion> _criteria, Weighting _weighting)
      Do an aggregation limited to the group 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.
      Parameters:
      _alternative - the alternative to aggregate for
      _group - the group the aggregation is limited to
      _criteria - the list of all criteria
      _weighting - the weighting for the criteria
      Returns:
      the aggregation value of the group

    • doAggregateSingle

      public double doAggregateSingle(Alternative _alternative, Criterion _criterion, ArrayList<Criterion> _criteria, Weighting _weighting)
      Do determine 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.
      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
