Problem of determining group judgement is to be solved when an aggregated opinion should be formulated on the basis of individual preferences. In general it is assumed that individual preferences are given in the order scale and that all the alternatives can be compared, i.e. linear orders are considered. However the latter assumption is not always satisfied. In such a case one can make use of partial rankings. Pairwise comparisons of alternatives provide a practical framework for acquiring information on ordinal preferences. In the paper the concept of binary comparisons matrix is presented. It can be applied to the problem of determining Kemeny’s median in the case when there are some incomparable alternatives in experts’ rankings. An integer optimization problem is formulated and some numerical examples are given. When experts provide their opinions in the form of linear orders the results obtained with classic as well as binary comparisons matrices are the same.
