Outranking-ScoreBin-WithPreferenceInformation_scores

Provider:PUT
Version:1.0.0

Description

Module for calculation ScoreBin scores using preference information given by decision maker. The preferences can be given as a complete pairwise comparison matrix where the value determines the degree of preference 0.0 or 1.0. The second type of preference input is to specify pairs of alternatives for which there is a preference.

Inputs

(For outputs, see below)

alternatives

Description:

Alternatives to consider.

preferences

Description:

Aggregated preferences binary matrix or pairs for which the outrank relationship occurs.

  • Tag: alternativesComparisons

preference information

Description:

Preference information about alternatives. Strength for the alternative is given to the value of true, weakness for false, when no value is given, the alternative does not gain strength or weakness.

parameters

Description:

First parameter specifies if preference are given by matrix or pairs. Second parameter specifies the algorithm to calculate ranking. There are three algorithms to choose from: PageRank, HITS and Salsa.

GUI information:

  • Parameter values can be defined via the GUI or the XMCDA file, by default via GUI.

  • Name: input type

    • Type: drop-down list
    • Possible values:
      • Preferences given by whole matrix 1-0 valued. (XMCDA label : matrix) (default)
      • Preferences given by pairs for whom the outranking relationship occurs (crisp). (XMCDA label : pair)
  • Name: algorithm type

    • Type: drop-down list
    • Possible values:
      • ScoreBin with preference information I (XMCDA label : scorebin_with_preference_information_1) (default)
      • ScoreBin with preference information II (XMCDA label : scorebin_with_preference_information_2)
      • ScoreBin with preference information III (XMCDA label : scorebin_with_preference_information_3)
  • Name: damping factor

    Damping factor

    • Constraint description: The real value must be between 0 and 1
    • Type: float
    • Default value: 0.15
  • Name: number of iteration

    Number of iteration

    • Constraint description: The value should be greater than 1
    • Type: integer
    • Default value: 100
  • Name: Run averaging if not converge?

    Turning on the version with averaging the score value, if after “number of iteration” iteration the score does not converge, that is: the maximum score difference between the last two iterations is greater than 0.001.

    • Default value: false
  • Name: Earlier stop if converge?

    Earlier stop if the maximum difference in score between two consecutive iterations is less than 0.00001

    • Default value: true
