1–9 scale rules.

Importance scale	Meaning
1	The former is as important to me as the latter j
3	The former i is slightly more important than the latter j
5	The former i is more important than the latter J
7	The former i is obviously important as the latter j
9	The former i is extremely important as the latter j
2, 4, 6, 8	The importance of i and j was taken as the middle value
Reciprocal of the above values	The importance degree of index i relative to index j is bij, and then the importance degree of index j relative to index i is b. = 1/bij
