Many organizations nowadays see their progress tied to competitive advantage over competitors, cost reduction, and customer satisfaction. A strong logistics system is a key factor in gaining competitive advantage over other organizations. The complexities involved in direct and reverse integrated processes prompts managers to opt for third-party logistics service providers as a suitable option for outsourcing processes. With the increase in the population and the expansion of the transportation network, the volume of industry-related products is increasing. One example of such products is tire, and the improper disposal of scrap tires has caused devastating damages to the environment. The review of literature suggests that only a limited number of studies have so far focused on the application of third-party logistics in tire supply chains, while their focus was mostly on direct or reverse tire flows under the production management. Therefore, this study proposed a dual-objective, multi-product, and multi-period mathematical model for designing closed-loop supply chain networks under third-party logistics management. The proposed model aims to maximize the profit of different scrap tire processes and advance social sustainability goals. The possibility of shared facility location and capacity constraints for different facilities was taken into account. This study also assessed the model's efficiency through a case study, and explored the model's behavior with certain parametric changes through sensitivity analysis. Furthermore, the two-objective model was solved using an Augmented epsilon-constraint method, and its optimal solution was investigated.
