Scale grade and state description.
Level of scale
State description
1
When node is compared with node , the quantization index of importance is 1, indicating that node and node are equally important
3
When node is compared with node , the quantization index of importance is 3, indicating that node is slightly more important than node
5
When node is compared with node , the quantization index of importance is 5, indicating that node is significantly more important than node
7
When node is compared with node , the quantization index of importance is 7, indicating that node is more important than node
9
When node is compared with node , the quantization index of importance is 9, indicating that node is extremely important than node
2, 4, 6, 8
When node is compared with node , the quantification index of importance is 2, 4, 6, or 8, indicating that node and node are in the middle of the above judgment
The scale grade is reciprocal
When node is compared with node , the quantified index of importance is , and when node is compared with node , the quantized index of importance is
