Abstract: The aim of this paper is to present a new way of aggregation two expert opinions. These opinions are disjoint and inconsistent, thus it is difficult to find a common solution using currently known methods. The authors suggest using horizontal membership function and RDM (Relative Distance Measure) method to get complete and unambiguous result. A general outline of this approach is presented and its equations are shown. The numerical example is given to illustrate the efficiency of the proposed method to practical issues in decision-making problems.
