Closed-Loop Supply Chain System Performance Evaluation by Using Exergoeconomics and Extenics

Using by the extension technique, the return threshold is evaluated first, then based on the exergoeconomics theory, the closed-loop supply chain is regarded as a huge energy system with the new view, and the sustainability of the closed-loop supply chain system is discussed under the circumstance of exergoeconomics in this paper, and then the metric about "system negative environment effect" is introduced to measure the closed-loop supply chain system performance in the point of energy, the numerical computing results illustrate our conclusion.
