Performance Evaluation by Using Exergoeconomics and Extenics Based on the Power Supply Chains

Using the extension technique, the return threshold is evaluated first, then based on the exergoeconomics theory, the supply chain is regarded as a huge energy system with the new view, and the sustainability of the 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 supply chain system performance in the point of energy, the case study illustrates our conclusion.
