A Stratified Fuzzy Decision-Making Approach for Sustainable Circular Supplier Selection

Abstract

Circular economy has attracted great attention as it meets environmental and social requirements. Selecting appropriate suppliers considering circular, and sustainability aspects for all industries is of great significance. However, addressing sustainable circular supplier selection (SCSS) problems is a difficult task due to the uncertainty in real-life cases in terms of possible future events and experts’ judgments. This article aims to address the SCSS problem considering the impacts of possible future events via a multiple-criteria decision-making framework. For this purpose, stratification theory is utilized to develop and practice a novel framework called stratified fuzzy full consistency method to identify the optimal weight coefficients of criteria considering the possible impacts o
