The greenhouse gas emissions (CO2, methane, etc.) and air pollution increase attention to develop and improve environmental strategies. Thus, environmental sanctions are forcing enterprises to re-consider and re-design supply chain processes in a green way. This paper provides a multi objective model to design a closed-loop supply chain (CLSC) network in a green frame. Our first and second objectives are minimizing the all transportation costs for forward and reverse logistics; third one is minimizing total CO2 emissions; fourth one is encouraging the customers to use recyclable materials as an environmental performance viewpoint. To provide a more realistic modeling by treating the uncertainty in decision maker's objectives, fuzzy modeling is approach is used in this study. The model is explained and tested via fulfilling a numerical example. In scenario analyses, Analytic Hierarchy Process (AHP), fuzzy AHP and fuzzy TOPSIS are applied and compared to evaluate different objectives.eninfo:eu-repo/semantics/closedAccessClosed-LoopGreenhouse Gas EmissionGreen Supply ChainMulti-Objective OptimizationAHPFuzzy AHPFuzzy TOPSISConference Object16171177WOS:000296892600029N/A
