Abstract

Many papers devoted to problems of group assessment of Pareto-optimal solutions or of compromise reaching in cooperative games were based on notions of utility functions or preference ordering identification. However, there is strong evidence that individual decision makers are apt to think in terms of goals or desirable levels of objectives rather than in terms of utility and preferences. Since reference objective levels can be used instead of weighting coefficients and utility functions to derive basic conditions for Pareto-optimality, they can also be applied to construct compromise-aiding procedures for cooperative games or for group assessment of Pareto-optimal solutions.

Several variants of such compromise-aiding procedures are investigated in the paper, together with deadlock situations and deadlock-resolving procedures.
