A tradeoff model for automotive closed-loop supply chain: An economic concerns-versus-greenness analysis

Due to increasing severity of the environment such as limited raw materials, increasing pollutions, global warming, environmental concerns are being more interesting in supply chain management. Especially in automotive supply chain, greenness has become a major concern so that car manufacturers have been obliged to recover at least ۹۵% End-Of-Life vehicle (ELV) by end of ۲۰۱۵. Therefore, since closed-loop logistics network make an infrastructure to collect and recover used products, developing an effective closed-loop network has been growing increasingly by researchers. Although Closed-loop logistics network touted as a major greening tool in supply chains, it causes increasing travel and CO۲ emission due to reverse logistics transporting. Then, balancing total cost and CO۲ emission in closed-loop supply chain is the major question. In this paper a Closed-loop supply chain network design problem with both economic and environmental concerns is presented. Therefore, a multi-objective optimization model that captures the trade-off between the total logistics cost and CO۲ emission is proposed
