What is it about?
The paper studied a closed-loop supply chain network design problem. The problem was formulated as a second-order conic program and solved directly by CPLEX after introducing a class of valid inequalities. Managerial insights related to closed-loop supply chain network design were explored.

Why is it important?
We proposed a second-order conic program for a closed-loop supply chain network design problem. A valid inequality was introduced to speed up the convergence of the solution procedure. Moreover, some interesting managerial insights were observed.
Perspectives
The work made further understanding of closed-loop supply chain network design and operations management.
