Abstract: To realize the rapid development of sustainable product,a method identifying critical functional modules for product sustainable design was proposed.The traditional customer demands was expanded to the sustainable needs such as environmental,economic and social demands,and these demands were translated into technology and function module terms to identify the critical function modules for sustainable design based on Quality Function Deployment (QFD).The environmental needs as the input of QFD were collected considering the environmental concerns during the whole life cycle stages of product by investigating.Through the sensitivity analysis of life cycle phase and environment require standards with the correlation analysis of life cycle stage and environmental impact evaluation index,the environmental impact contribution of different life cycle stages was obtained,which were integrated with the environmental concerns survey research to obtain the weight of environmental needs.By integrating Analytic Hierarchy Process (AHP) and KANO model,the economic and social demands and their weights were got.The identifying process of strip rectifying control system was as an example to demonstrate the rationality and feasibility of the proposed method.
