An Extended Step-Wise Weight Assessment Ratio Analysis with Symmetric Interval Type-2 Fuzzy Sets for Determining the Subjective Weights of Criteria in Multi-Criteria Decision-Making Problems

摘要: Determination of subjective weights, which are based on the opinions and preferences decision-makers, is one most important matters in process multi-criteria decision-making (MCDM). Step-wise Weight Assessment Ratio Analysis (SWARA) an efficient method for obtaining weights criteria MCDM problems. On other hand, decision-makers may express their with a degree uncertainty. Using symmetric interval type-2 fuzzy sets enables us to not only capture uncertainty information flexibly but also perform computations simply. In this paper, we propose extended SWARA determine group decision-makers. The determined by proposed approach involve decision-makers’ form makes them more interpretable. To show procedure approach, it used importance intellectual capital dimensions components company. results that determining capturing information.
