Definition of importance scale of judgment matrix A.
| Scaling (aij) | Importance |
| 1 | i and j are equally important | 3 | i is slightly more important than j | 5 | i is obviously more important than j | 7 | i is far more important than j | 9 | i is significantly more important than j | 1/3 | j and i are equally important | 1/5 | j is obviously more important than i | 1/7 | j is far more important than i | 1/9 | j is significantly more important than i | 2, 4, 6, 8 | The middle of each scale |
