Inputs

(For outputs, see below)

criteria

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.

The input value should be a valid XMCDA document whose main tag is <criteria>. It must have the following form:

<criteria>
    <criterion>
        <active>[...]</active>
        <thresholds>
            <threshold
                    mcdaConcept="indifference"><!-- REQUIRED, must be indifference, preference or veto  -->
                    <constant><real>[...]</real></constant>
            </threshold>
         </thresholds>
         [...]
    </criterion>
    [...]
</criteria>

alternatives

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.

The input value should be a valid XMCDA document whose main tag is <alternatives>. It must have the following form:

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

performanceTable

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

The input value should be a valid XMCDA document whose main tag is <performanceTable>.


criteriaWeights

The set of criteria weights.

The input value should be a valid XMCDA document whose main tag is <criteriaValues>.


valuationDomain (optional)

Indicates the minimal and the maximal values of the valuation domain for computing the concordance 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.

The input value should be a valid XMCDA document whose main tag is <methodParameters>. It must have the following form:

<methodParameters
         name="valuationDomain"> <!-- REQUIRED  -->
    <parameter
         name="min"> <!-- REQUIRED  -->
        <value>
            <integer>%1</integer>
        </value>
    </parameter>
    <parameter
         name="max"> <!-- REQUIRED  -->
        <value>
            <integer>%2</integer>
        </value>
    </parameter>
</methodParameters>

where:

  • %1 is a parameter named “min”. This is a float.
  • %2 is a parameter named “max”. This is a float.

Outputs

alternativesComparisons

The concordance relation.

The returned value is a XMCDA document whose main tag is <alternativesComparisons>.


messages

A list of messages generated by the algorithm.

The returned value is a XMCDA document whose main tag is <methodMessages>.
