摘　　要：根据数控机床绿色度评价指标具有多层次、多因素且定量与定性指标并存的特点,提出应用模糊可拓层次分析法评价数控机床绿色度的方法。该方法利用可拓区间数定量表示各指标间的相对重要程度,较传统层次分析法更科学、合理。通过专家打分建立可拓区间判断矩阵,计算各层次评价指标权重,结合模糊综合评价法进行逐级评价,最终得出综合评价值。以加工中心为实例进行评价,结果表明其绿色度处于中等水平,与实际相符。A method applying the fuzzy extension analytic hierarchy process （EAHP） method is proposed to evaluate the green degree of CNC machine tool whose evaluation indexes of green degree can be qualitative and quantitative and multi-hierarchic. It can quantitatively show the relative important degree between indexes with the extension interval number. By the extension interval judging matrix of evaluation index constructed by the experts, the weight of the indexes is identified and the green degree is evaluated step by step with fuzzy synthetic evaluation method. At last the result of synthetical green degree is obtained with fuzzy comprehensive evaluation method. An example with machining center is given to evaluate its green degree. The result shows that the green degree of the machining center is medium. It is consistent with the reality.
