Abstract

Purpose - Supplier selection considering economic, environmental and social sustainability issues has been attempted in this case empirical study. Design/methodology/approach – Subjective human judgment bears some kind of vagueness and ambiguity; fuzzy set theory has immense potential to overcome this. Owing to the advantage of intuitionistic fuzzy numbers set over classical fuzzy numbers set; three decisionmaking approaches have been applied here in intuitionistic fuzzy setting (viz. intuitionisticTOPSIS, intuitionistic-MOORA and intuitionistic-GRA) to facilitate supplier selection in sustainable supply chain. Findings – The stated objective of this research “to verify application potential of different decision support systems (in intuitionistic fuzzy setting) in the context of sustainable supplier selection” has been carried out successfully. A case empirical research has been conducted by applying three different decision making approaches: Intuitionistic Fuzzy-TOPSIS (IFTOPSIS), Intuitionistic Fuzzy-MOORA (IF-MOORA) and Intuitionistic Fuzzy-GRA (IFGRA) to an empirical data set of sustainable supplier selection problem. The ranking orders thus obtained through exploration of aforesaid three approaches have been explored and compared. Originality/value – As compared to generalized fuzzy numbers, intuitionistic fuzzy numbers exhibit a membership degree, a non-membership degree and the extent of hesitation; a better way to capture inconsistency, incompleteness and imprecision of human judgment. Application potential of aforesaid three decision support approaches has been demonstrated in this reporting for a case sustainable supplier selection.

7. Conclusion

The contributions of aforesaid research have been summarized below.

1. Adaptation to a list of criteria from sustainability perspective to facilitate supplier selection. Sustainability encompasses of economic, social as well as environmental sustainably. The selection criteria on the basis of three sustainability dimensions have been accumulated through literature review and these have been utilized for effective decision making.

2. Owning to the advantages of intuitionistic fuzzy set over generalized fuzzy set, application potential of intuitionistic-TOPSIS, intuitionistic-MOORA and intuitionistic-GRA have been attempted to a sustainable supplier selection problem. The similar ranking order of candidate suppliers thus obtained supports consistency of aforesaid three decision support tools in intuitionistic fuzzy setting. A variety of decision support tools based on the concept of intuitionistic fuzzy numbers set theory could be well articulated from existing literature; however, application of these decision support tools in the context of sustainable supplier selection has rarely been addressed.

3. The specialty of the decision support tools attempted in the present work is that these tools consider importance (weight) of the decision-makers. In most of the decision making approaches, weights the decision-makers are assumed equal; means their opinions are equally important.

4. Apart from applying Ratio System part of intuitionistic-MOORA, which is readily available in existing literature, the current research extends intuitionistic-MOORA by introducing Reference Point Approach. The formulations of Reference Point Approach in intuitionistic fuzzy setting have been developed herein. It has been observed that both Ratio System Approach and Reference Point Approach provide similar ranking order of candidate suppliers.
