A Bi-objective Closed-loop Green Supply Chain Design

Nowadays by growing attention to environmental issues, industries are seeking ways to reduce thepollution of environment. Clearly, if firms and industries want to be survived in competitive market, theyshould take into account the concerns and reduce total costs. Therefore, they should apply greenpractices into their supply chains. In order to optimize total costs and co2 emissions, this paper proposesa green closed-loop supply chain model by using bi-objective mixed integer programming; this model canbe practical and help managers design their supply chains. Finally, a numerical example is presented toillustrate the model.
