The Application of Improved DEA Method in the Green Supply Chain Performance Evaluation

This paper starts from the production of green supply chain. it describes the concepts of green supply chain and performance evaluation. According to the idea of green supply chain and considering the characteristics of the Green Supply Chain, this paper established a green supply chain performance evaluation system. This system made clear choice of evaluation index. Finally, by improving the data envelopment analysis (DEA) and MATLAB software-assisted calculation complete the evaluation of green supply chain performance. And combined with examples, this paper explainsed the improved data envelopment analysis (DEA) is more conducive to the whole sort of decision-making unit than the traditional data envelopment analysis (DEA).
