In this research, an NPV optimization model for multi-period multi-product closed-loop supply chain network design and planning is developed to maximize the total NPV. The effect of interest rates on profit and performance, the effect of the maximum return ratio on the overall NPV of the system and the effect of interest rate change on the network configuration are studied.}, journal = {American Journal of Engineering and Applied Sciences}, publisher = {Science Publications} }
