This web service allows to compute a concordance relation as defined in the Rubis methodology.

Inputs

valuationDomain

Description:

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.

GUI information:

-Status: define parameter value via XMCDA file or input by hand, by default via input by hand.

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.
