All proposed solutions are based on the concept of fuzzy majority. It is argued that this implies a human consistent framework for consensus reaching support. This framework makes it possible to model individual preferences, calculate degrees of consensus, perform analyses of the group´s structure and aggregate preferences consistently with the human perception
