One topic under discussion of the analytic hierarchy process is the use of different scales in order to translate judgments into ratios. The author shows that the so-called balanced scale has a uniform weight distribution for two decision criteria only. If it is applied to decision problems with more than two criteria, weights are no longer balanced, and priorities are underweighted. A generalization of the balanced scale is proposed, which takes into account the number of decision criteria. It is shown that the generalized balanced scale yields equally dispersed local weights for any number of decision criteria.
