A Method for Determining Priorities Between Competing Interval-Valued Estimates of Experts

Experts may differ in their estimates while making a decision. Therefore, how to aggregate opinions of different experts is still an open issue. The paper deals with the problem of priorities for competing interval-valued estimates made by different experts. The simple method of determining priorities is proposed. The procedure of the method includes separate aggregation of estimates of probabilities of opposite hypotheses and subsequent comparison of aggregated estimates. An aggregation is performed by solving an optimization task. A numerical example is used to illustrate proposed method.
