(eng): The theory of cooperative games with vague cooperation is based on the model of fuzzy coalitions as fuzzy subsets of the set of all players who participate in the coalitions with some part of their power. Here, we suggest an alternative approach assuming that coalitions are formed by relatively compact groups of individual players each of which represents a specific and joined interest. Each individual player may participate in several such groups and, as their member, in several coalitions.
