A Multi-Criteria Evaluation for Sustainable Supplier Selection Based on Fuzzy Sets
Özet
It is well known that sustainability strategies have moved further and further
up over the past decade due to help companies to improve the effectiveness of their
marketplace and perform better in their operations. For companies, sustainability would
gain long-term consequences such as getting greater profits and creating their own
consumer path. The Triple Bottom Line (TBL) is a key element of the companies to
achieve social, environmental, and economic benefits. Supplier’s performance directly
affects a company’s performance not only environmental or economic issues but also
sustainable issues. Thus, Sustainable Supplier Selection (SSS) has become the highly
relevant topic and many authors and researchers have focused on this subject. This
study investigates a hybrid multi-criteria decision making (MCDM) framework based on
TBL to determine sustainable suppliers. After construction of hierarchy, the integrated
fuzzy MCDM algorithm is implemented. At first, Fuzzy Analytical Hierarchy Process
(FAHP) is used for obtaining the weights of the main criteria and related sub-criteria.
Then, fuzzy TOPSIS method is applied for ranking the suppliers. Additionally, interval
type-2 fuzzy sets (IT2FSs) that express uncertainty better than traditional type-1 fuzzy
sets are used for selecting an appropriate supplier. The proposed approach is validated
