The majority preference relation based on cone preference relations of the decision makers
A multicriteria group choice problem is considered in the paper. The model
includes a set of feasible alternatives, a vector criterion, and n preference
relations of the decision makers (DMs). Each preference relation is a cone
relation with corresponding properties. It is considered the majority
preference relation, as a cone relation constructed upon the cones of the DMs'
preference relations. It is shown how to use and aggregate additional
information about the DMs' preference relations in case of three DMs and two
criteria. The Pareto set of multicriteria problem with "new" vector criterion
forms a group choice, which reduces the Pareto set of initial multicriteria
problem.Comment: Proceedings of 2nd International Conference on Information Technology
