Multi-Objective Sustainable Closed-Loop Supply Chain Network Design Considering Multiple Products with Different Quality Levels

International laws and increasing consumer awareness have led to drastic changes in traditional supply chain network designs. Moreover, because of environmental social requirements, networks changed sustainable networks. On the other hand, reverse logistics can be effective terms economic aspects, so design as a closed loop is necessary. In addition, customers demand for different products with quality levels. Considering types variety consumption trends challenging issue, addressed this study. The main contributions research are considering levels well tendencies towards issues. study, closed-loop model designed that seeks balance economic, environmental, responsibilities. paper, costs customer demands at considered under uncertain conditions using robust possibilistic programming method. proposed multi-objective solved Augmented Epsilon Constraint (AEC) method provides an efficient set solutions all decision-making results show more dealing uncertainties than
