Table 7
Possible scales used for AHP’s pairwise comparison [
1].
| | Relative intensity | Definition | Explanation |
| | 1 | Of equal value | Two requirements are of equal value | | 3 | Slightly more value | Experience slightly favors one requirement over another | | 5 | Essential or strong value | Experience strongly favors one requirement over another | | 7 | Very strong value | A requirement is strongly favored and its dominance is demonstrated in practice | | 9 | Extreme value | The evidence favoring one over another is of the highest possible order of affirmation | | Intermediate values between two adjacent judgments |
When comprise is needed | | Reciprocals |
If requirement i has one of the above numbers assigned to it when compared with
requirement j, then j has the reciprocal value when compared with i |
