Calculates possible and necessary assignments of alternatives to classes (categories) using Robust Ordinal Regression for value-based sorting. It is possible to provide an additional optional preference information: example alternatives assignments, assignment pairwise comparisons and desired class cardinalities. Service developed by Krzysztof Ciomek (Poznan University of Technology, under supervision of Milosz Kadzinski). https://github.com/kciomek/rorutadis A list of criteria (<criteria> tag) with information about preference direction (<criteriaValues mcdaConcept="preferenceDirection">, 0 - gain, 1 - cost) and number of characteristic points (<criteriaValues mcdaConcept="numberOfCharacteristicPoints">, 0 for the most general marginal utility function or integer grater or equal to 2) of each criterion.

A comparison from list with attribute mcdaConcept="atLeastAsGoodAs" indicates that some alternative should be assigned to class at least as good as class of some other alternative (k = 0) or at least better by k classes (k > 0). A comparison from list with attribute mcdaConcept="atMostAsGoodAs" indicates that some alternative should be assigned to class at most better by k classes (k > 0) then some other alternative.
