Additive synthesis of ratio scales requires the scales to be in a common unit of measure. Unlike regular ratio scales, the unit of measure for relative ratio scales is not readily identifiable. That obscurity complicates the problem of achieving commensurability before multiple scales are synthesized. Examples are given of how conventional AHP may fail to aggregate commensurable values. Several techniques are presented that address the issue of commensurability. The analysis is then extended to more complex forms of aggregation such as benefit/cost analysis and the ANP.
