In today's market, companies frequently resort to outsourcing to maintain their market position and gain a competitive edge. This approach significantly increases the number of stakeholders, i.e., suppliers, subcontractors and third-party reverse logistics partners (3PRLPs) within the supply chain. Achieving effective sustainability strategies across the supply chain relies on fostering trust and collaboration among these stakeholders. This study aims to develop a closed-loop, complex supply chain network that integrates strategic and tactical decisions-including partner selection, order allocation, aggregate production planning (APP), and network flow optimization-to meet the expectations of both internal and external stakeholders while achieving the three fundamental objectives of sustainability: economic, environmental, and social. To illustrate the proposed model, a real-life application of a 100% cotton T-shirt supply chain in the Turkish textile industry is presented. The proposed model is solved using the augmented epsilon constraint method, and the results are compared.
