Abstract
Majority of approaches in group decision consist in aggregating many individual decisions into one group decision. In this paper a different approach is proposed which is based on the idea of representation of a variety of decisions by a single decision, which could be considered as a most typical. representing the all essential features of given decisions. Such a decision is referred to as a compromise decision. Goodness of representation is defined from three different points of view. All these approaches are equivalent, provided some mild conditions are satisfied.
