ElectreIVCredibility

Provider:PUT
Version:0.2.0

Description

ElectreIVCredibility - computes credibility matrix as presented in Electre IV method.

The key feature of this module is its flexibility in terms of the types of elements allowed to compare, i.e. alternatives vs alternatives, alternatives vs boundary profiles and alternatives vs central (characteristic) profiles.

Electre IV is a method based on the construction of a set of embedded outranking relations (similarly to Electre III). There are five such relations, and every subsequent one accepts an outranking in a less credible circumstances.

Please note that Electre IV is not the same method as Electre Iv.

Inputs

(For outputs, see below)

criteria

Description:

Criteria to consider, possibly with preference, indifference and veto thresholds. Each criterion must have a preference direction specified (min or max).

alternatives

Description:

Alternatives to consider.

  • Tag: alternatives

performance_table

Description:

The performance of alternatives.

XMCDA related:

  • Tag: performanceTable

profiles_performance_table

Optional: yes, enabled by default

Description:

The performance of profiles (boundary or central).

method_parameters

Description:

This parameter specifies the type of elements provided for comparison.

Choosing ‘boundary_profiles’ or ‘central_profiles’ requires providing inputs ‘classes_profiles’ and ‘profiles_performance_table’ as well (which are optional by default).

GUI information:

  • Parameter values can be defined via the GUI or the XMCDA file, by default via GUI.
  • Name: comparison_with
    • Type: drop-down list
    • Possible values:
      • alternatives vs alternatives (XMCDA label : alternatives) (default)
      • alternatives vs boundary profiles (XMCDA label : boundary_profiles)
      • alternatives vs central (characteristic) profiles (XMCDA label : central_profiles)
