A scheme selection method on the base of super efficiency DEA (DEA, data envelopment analysis) is put forward in order to design an energy-saving product. Firstly, a fishbone figure from the point of view of life cycle is established for the sake of analyzing energy-consumption factors systematically. Secondly, as the restriction of basic DEA model, super efficiency model of DEA is referred to choose the potentially energy-saving project. In view of the high difficulty in acquiring energy-consumption factors, this paper takes all the factors into account to select the scheme of energy-saving design. Finally an example of a blade at the stage of manufacture is introduced to illustrating this model. The achievements above solve the problem of the selection of energy-saving scheme, which provide significant references for product energy-saving design.
