Between the numerator and denominator, there is a fine line.Only a fraction appreciates the distinction of what is above or below that line.The denominator and the "of what" is the unit in a pairwise comparison and in priority vectors.Pairwise comparisons provide the unit conversions between the elements being compared.These relationships are key to the problem definition and representation.As we understand what is above and below the fine line we come to recognize, appreciate, and respect the unit.In AHP/ANP it is important to recognize the nature of the problem and how units are used to represent it.
