Relative importance described by the triangular fuzzy numbers.
Relative importance in qualitative description
Description
Triangular fuzzy number
Equally important
Both indexes contribute equally to the target fire risk
(1, 1, 2)
Between equally and slightly important
Between the front and the back
(1, 2, 3)
Slightly important
Based on the objective judgment and expert experience, it is considered that one index contributes slightly more to the target fire risk than another
(2, 3, 4)
Between slightly and strongly important.
Between the front and the back
(3, 4, 5)
Strongly important
Based on the objective judgment and expert experience, it is considered that the contribution of one index to the target fire risk is better than another
(4, 5, 6)
Between strongly and very strongly important
Between the front and the back
(5, 6, 7)
Very strongly important
The index’s contribution to the target fire risk is significantly better than another
(6, 7, 8)
Between very strongly and absolutely important.
Between the front and the back
(7, 8, 9)
Absolutely important
There is evidence that one index is definitely better than another for the target fire risk
