Green Supplier Selection Based on the Combination of Fuzzy SWARA (SWARA-F) and Fuzzy MARCOS (MARCOS-F) Methods

The green supply chain operations try to minimize environmental impact over the product's lifetime including product recycling or use, reduction of harmful substances, resource saving, design, etc. Supplier selection is vital issue in purchasing. This paper aims develop applicable and efficient methodology for supplier selection. proposed includes combination Fuzzy Stepwise Weight Assessment Ratio Analysis (SWARA-F) Measurement Alternatives Ranking according COmpromise Solution (MARCOS-F) methods. extensions these methods are preferred because complexity problem inclusion both quantitative qualitative criteria. Also, criteria may be uncertain conflict with each other. It first time that SWARA-F combined MARCOS-F assessment best one among them. effectiveness demonstrated by solving real a company from textile industry. In classic main sub-criteria considered. used weighting evaluation rank alternatives obtained incomplete information score calculated MARCOS-F. two verified sensitivity comparative analyses. provides acceptable satisfactory results determining namely improving cost efficiency process.
