An Approach to Determining Attribute Weights Based on Integrating Preference Information on Attributes with Decision Matrix

Table 1

Experts’ subjective preference information on attributes.

	c1	c2	c3	c4
(preference orderings)	3	2	4	1
(linguistic terms)	Fair	Important	Unimportant	Very important
(interval numbers)	[0.10, 0.30]	[0.15, 0.35]	[0.15, 0.20]	[0.25, 0.40]
(inequality constraints among attribute weights)
