The green supply chain management based on EMS

Discussing the impact of environmental factors in the supply chain management is a hot issue at home and abroad. This paper begins with a brief analysis of the contents of green supply chain management and the obstacles in the environmental management process. Then we do some research on how to carry green supply chain management out considering environmental management systems, by environmental management process and definiting transfer function to quantify description the environmental management system. Based on the theory of fuzzy entropy, we establish the green supply chain environmental management decision support model, then extent environmental management to the entire green supply chain management, in order to minimize the environmental impact of the entire system.
