Linguistic variables for the important weight of each criterion.

Linguistic values	Triangular fuzzy numbers
Just equal	(1, 1, 1)
Equally important (EI)	(1/2, 1, 3/2)
Weakly more important (WMI)	(1, 3/2, 2)
Strongly more important (SMI)	(3/2, 2, 5/2)
Very strongly more important (VSMI)	(2, 5/2, 3)
Absolutely more important (AMI)	(5/2, 3, 7/2)
