Abstract: The invention provides a decision support method for two or more pre-defined criteria and two or more profiles. Each criterion comprises two or more pre-defined and ordinally ranked categories. Each profile comprises a set of two or more of the criteria. Each criterion in the set is associated with one of the categories for that criterion. The method performs a comparative assessment of profiles involving an ordinal pairwise ranking of profile pairs. The method further comprises solving a system of equalities/inequalities that represents the ordinal pairwise rankings of profile pairs to obtain a point value for each category on each criterion and/or a ranking of all possible profiles and/or a ranking of a subset of all possible profiles. The invention also provides a related system and computer program.

Abstract: The invention provides a decision support method comprising: for two or more predefined criteria each criterion associated with one or more pre-defined categories, determining a point value for each category on each criterion by the pairwise ranking of profile pairs wherein each profile comprises a set of two or more of the criteria, each criterion in the set instantiated with one of the categories for that criterion. The invention also provides a related system and computer program.
