针对数控装备质量多层次指标评价问题，提出了一种基于模糊物元模型的综合评价方法。该方法利用模糊物元理论分析多个质量特性及其属性特征，并建立了数控装备质量综合评价模型。采用层次分析法和信息熵确定评价指标权重，建立基于最小二乘法的优化组合权重模型计算组合权重，并运用模糊物元法给出评价结果。实例研究表明该方法可行、合理。

A comprehensive evaluation method based on fuzzy matter element analysis is proposed to solve problems of multiple performance and quality evaluation for computer numerical control (CNC) equipment. The fuzzy matter element theory is utilized to analyze multi-scale quality characteristics and attributes. Then, the comprehensive quality evaluation model for CNC equipment is founded by using fuzzy matter element analysis method. Analytic hierarchy process (AHP) and information entropy are applied to obtain the objective index weights. Furthermore, the combinational weight is calculated with the optimal mathematics model based on the least square method. Finally, the fuzzy matter element method is used to determine the assessment result. The case study indicates that the method has a certain rationality and feasibility.
