Research on recycling of CNC machine tools based on fuzzy analytic hierarchy process

According to the idea of green manufacturing, recycling of CNC machine tools is researched. Flow chart of CNC recycling is analyzed, after several evaluation methods compared, the fuzzy analytic hierarchy process and linear weighting method are presented to evaluate the CNC machine tools recycling, evaluation indexes selected principles are researched, and then a comprehensive and rational evaluation index system of CNC machine tools recycling is established and a prototype system is developed based on theory study. It provides theoretical and technical reference for the recycling of CNC machine tools.
