The UTA^GMS/GRIP Methods

The UTA^GMS and GRIP methods aim at solving the multiple criteria ranking problem. The underlying preference model is a set of monotone additive value function compatible with preference statements expressed by the decision maker. The main result of these methods is :

• a necessary (robust) ranking that contains comparisons of alternatives that remain valid for all compatible value function,
• a possible ranking that contains comparisons of alternatives that are valid for at least one compatible value function.
