Proposed linguistic terms for the triangular fuzzy number conversion scale (adapted from [1]).

AHP-based fuzzy terms	Equivalent fuzzy number/reciprocal		Equivalent triangular fuzzy
	Number	Reciprocal	Number	Reciprocal
Equal important			(1, 1, 1)	(1, 1, 1)
In between			(1, 2, 3)	(1/3, 1/2, 1)
Moderately important			(2, 3, 4)	(1/4, 1/3, 1/2)
In between			(3, 4, 5)	(1/5, 1/4, 1/3)
Highly important			(4, 5, 6)	(1/6, 1/5, 1/4)
In between			(5, 6, 7)	(1/7, 1/6, 1/5)
Very highly important			(6, 7, 8)	(1/8, 1/7, 1/6)
In between			(7, 8, 9)	(1/9, 1/8, 1/7)
Extremely important			(8, 9, 9)	(1/9, 1/9, 1/8)
