Inputs

(For outputs, see below)

criteria

Description:

A list of criteria. Criteria can be activated or desactivated via the <active> tag (true or false). By default (no <active> tag), criteria are considered as active.
Using thresholds is optional, only the constant ones with mcdaConcept equals to “indifference”, “preference” or “veto” will be considered.

alternatives

Description:

A list of alternatives. Alternatives can be activated or desactivated via the <active> tag (true or false). By default (no <active> tag), alternatives are considered as active.

        </alternative>
        [...]
    </alternatives>
    

performanceTable

Description:

A performance table. The evaluations should be numeric values, i.e. <real>, <integer> or <rational>.

valuationDomain

Description:

Indicates the minimal and the maximal values of the valuation domain for computing the outranking relation. By default the valuation domain is {0,0.5,1}. The median indetermination value is computed as the average of the minimal and the maximal values.

GUI information:

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

  • Name: min

    Indicates the minimal value of the valuation domain.

    • Type: float
    • Default value: 0
  • Name: max

    Indicates the maximal value of the valuation domain (which should be greater than the minimal value).

    • Type: float
    • Default value: 1
