Abstract: Abstract This paper suggests ranking alternatives through a centroid based fuzzy weighted average (FWA) approach, where ratings of alternatives versus subjective criteria and the importance weights of all criteria are assessed in linguistic values represented by fuzzy numbers. Membership functions of the final fuzzy evaluation values of alternatives can be developed and the centroid ranking method is applied to defuzzify all the final fuzzy evaluation values to complete the model. Formulae of ranking procedure can be clearly developed to make execution of the proposed method more efficient. An example demonstrates feasibility of the proposed method.
