A vector projection method to evaluating machine tool alternatives for green manufacturing

Machine tool selection for green manufacturing is a practical approach for reducing the resource consumption and negative environmental impact in mechanical processes. On the other hand, selecting the best machine tool from its increasing number of existing alternatives in market are multiple-criteria decision making problem in the presence of many quantitative and qualitative attributes. Therefore, in this paper, a reference index system is setup for the machine tool selection by the consideration of resource consumption and environmental impact. A machine tool selection model is established, and a methodology so called Vector Projection Method is developed to justify machine tool alternatives. Lastly, an example is discussed.
