摘要
针对层次分析法评价机床设计质量时未考虑区间灰度以及判断矩阵调整困难等问题,提出了一种基于灰色理论和模糊层次分析法的机床设计质量评价方法。笔者分析了设计质量评价内涵,构建了具有通用性的机床设计质量评价体系,应用了灰色理论使区间灰数的白化处理与模糊层次分析法相结合,并将其用于质量综合评价。评价过程设有灰度等级,同时设有评价等级,将定性评价与定量评价相结合,使评价结果更合理;对每个层次都进行权重分配,并用关联系数对权值进行了修正,使评价过程更科学。最后,以五轴机床为例验证该方法对机床设计质量综合评价的可行性。灰色模糊层次分析法可以科学有效地评价机床的设计质量,准确地给出产品质量评估等级。
In order to solve the ignored interval gray level and the difficult judgment matrix adjustment in the evaluation of the design quality of machine tools by using analytic hierarchy process （AHP）, a method based on gray theory and fuzzy analytic hierarchy process （FAHP） was proposed. The design quality evaluation was deeply analyzed, a universal evaluation system for design quality of machine tools was established and the grey theory was applied to evaluate the design quality by the combination of interval gray number and fuzzy hierarchy. The evaluation process was equipped with gray level and evaluation grade, combining qualitative evaluation and quantitative evaluation, which made the final results more reasonable. The weight was assigned to each level and was modified with correlation coefficient to make the evaluation process more scientific. Finally, the feasibility of the method in the comprehensive evaluation of design quality of machine tools was proved by the example of a five-axis machine tool. The results show that the design quality of machine tools can be evaluated by grey fuzzy analytic hierarchy process scientifically and effectively, and the grade of product quality evaluation can be provided accurately.
