A new integrated group decision making framework with linguistic interval fuzzy preference relations

Abstract

Abstract The high complexity of socio-economic environments often makes it difficult for a single decision maker (DM) to consider all important aspects of decision problems. Therefore, a group decision making (GDM) process is often preferred by organizations. Moreover, during the decision process, DMs may have difficulties in the prioritization of alternatives. Linguistic interval fuzzy preference relation is a strong tool which can deal with uncertainty in case of subjective and vague information. For this reason, this paper develops a new GDM approach based on integrated linguistic interval fuzzy preference relation and analytic network process. To demonstrate the applicability of the proposed approach, an illustrative example is presented. © 2013. The authors-Published by Atlantis Press.
