Table 4 Judgment matrix index importance level numerical scale table.
Scale value | Importance level | Implication |
|---|---|---|
1 | Equally important | Indicator i is of equal importance compared to indicator j |
3 | Slightly important | Indicator i is slightly important compared to Indicator j |
5 | Obviously important | Indicator i is obviously important than Indicator j |
7 | Significantly important | Indicator i is significantly important compared to Indicator j |
9 | Absolutely important | Indicator i is absolutely important compared to Indicator j |
2,4,6,8 | Intermediate value | The importance level is between two adjacent levels |
1/2,1/3…1/9 | Reverse comparison | If the importance scale of indicator i over indicator j is "n", the reverse comparison is "1/n" |
