%X The use of interval judgments instead of accurate pairwise comparisons  has been proposed as a solution to facilitate the analysis of  uncertainties in the widely applied pairwise comparisons technique. A  method is presented for deriving probability distributions for the  pairwise comparisons and for utilizing the distributions in the analysis  of uncertainties in the evaluation process. The first step is that the  expert or the decision-maker is queried as to the best guess of the  priority ratio of the attributes compared. This is followed by an  adjusting query concerning the uncertainty in the comparison: what is  the probability of the priority ratio being between the best guess ± 1  unit of the pairwise comparison scale? An application of the method is  presented in the form of multiple-criteria evaluation of alternative  management plans for a forest area.
