Taguchi Loss Function in Intuitionistic Fuzzy Sets along with Personal Perceptions for the Sustainable Supplier Selection Problem

Sustainability, a new interdisciplinary paradigm, can be defined as standard in terms of economic, environmental and social awareness company. In many applications, theoretical sustainability models considering the importance three aspects equally differed from used practice. A sustainable supplier selection problem generally contains conflicting information imprecise decision makers’ knowledge, makers judge suppliers based on their first impression. Hence, this study, plastic packaging company Turkey is taken into account under an expert-based model theorical-based for scenarios which consider personal perceptions makers. First, intuitionistic fuzzy set-based method applied to using two different distance measurement approaches, namely, normalized Euclidean Taguchi loss function, alternative proposed. Then, are ranked validity results also checked Pearson product–moment correlation coefficient. The indicate that (i) perception has inevitable impact results, (ii) proposed approach capture associated uncertainties embedded environment, (iii) there disparity between theory reality sustainability.
