Abstract:

In the paper a heuristic procedure of determining the Kemeny median is presented. It is assumed that all the alternatives are compared and ties may occur in experts’ opinions as well as in group rankings. The loss matrix is applied to derive the solution. Lower bound of a distance of a given ranking from experts’opinions is evaluated for the case of ties in group ranking. It is also shown that the procedure of determining the Kemeny median can be simplified by means of the analysis of the loss matrix.
