Green products can reduce the environmental burden during design and disposal. The most approved technique to evaluate the environmental profile of a green product is the life cycle assessment. Data mining has also been successfully applied in many fields. However, little research has been done in the quality function deployment of mining the dynamic trends of customer requirements and engineering characteristics, using data mining and grey theory. This paper proposed an approach to use data mining and grey theory in quality unction deployment for mining dynamic trends of the computer life cycle-oriented green supply.
