This web service allows to compute a concordance relation as defined in the Rubis methodology. R. Bisdorff, P. Meyer, M. Roubens, Rubis: a bipolar-valued outranking method for the best choice decision problem, 4OR, 6 (2), June 2008, Springer (doi:10.1007/s10288-007-0045-5). 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. [...] [...] [...] [...] ]]> 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. [...] [...] [...] ]]> A performance table. The evaluations should be numeric values, i.e. <real>, <integer> or <rational>. The set of criteria weights. 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. %1 %2 ]]> Indicates the minimal value of the valuation domain. Indicates the maximal value of the valuation domain (which should be greater than the minimal value).
