Abstract

One of the strengths of the Analytic Hierarchy Process (AHP) is that it allows decision-makers to specify their preferences using a verbal scale. Yet, as is well known, a strict reliance on the corresponding Saaty 1-9 numeric scale can induce some inconsistency. Hence we argue that, in certain situations, it may be appropriate to calibrate the verbal scale. The result of this calibration is a geometric scale based on a single parameter. We present some limited evidence that this geometric scale marginally outperforms the Saaty 1-9 scale. Moreover, we suggest that this calibration can be used to do a simple sensitivity analysis in cases where judgements are uncertain.
