针对零件加工机床设备优选的问题,分析了影响机床设备选择的约束因素,建立了一种两级结构的多目标优选模型,包括加工时间 T、加工质量 Q、加工成本C、资源消耗 R、环境影响 E在内的5个优化目标;针对传统层次分析法(AHP)在构建机床设备优选判断矩阵时没有考虑评价工程师主观模糊性和指标属性的模糊性,导致机床设备优选的可信度和准确性降低的问题,提出并设计了基于三角模糊数的模糊层次分析法(FAHP)及模糊综合评价(FC A )用于机床设备优选的模型算法。在评价指标标准化阶段,采用隶属度函数进行数据标准化处理。结合某航空制造企业叶片榫头铣削用机床设备优选的案例,验证了该方法的可行性和有效性。
針對零件加工機床設備優選的問題,分析瞭影響機床設備選擇的約束因素,建立瞭一種兩級結構的多目標優選模型,包括加工時間 T、加工質量 Q、加工成本C、資源消耗 R、環境影響 E在內的5箇優化目標;針對傳統層次分析法(AHP)在構建機床設備優選判斷矩陣時沒有攷慮評價工程師主觀模糊性和指標屬性的模糊性,導緻機床設備優選的可信度和準確性降低的問題,提齣併設計瞭基于三角模糊數的模糊層次分析法(FAHP)及模糊綜閤評價(FC A )用于機床設備優選的模型算法。在評價指標標準化階段,採用隸屬度函數進行數據標準化處理。結閤某航空製造企業葉片榫頭鐉削用機床設備優選的案例,驗證瞭該方法的可行性和有效性。

To provide evidence for enterprises to choose the best machine tool ,the constraint fac‐tors affect machine tool selection optimization w as analyzed and the multi‐objects optimization model for machine tool selection was built with a two‐stage structure and with five optimization objects include processing time T ,processing quality Q ,processing cost C ,resources consump‐tion R and environment impact E .Because the traditional analytic hierarchy process (AHP) did not take the fuzziness of engineers′subjective assessment and index attributes into consideration during the construction of machine tool selection optimization judgment matrix ,the reliability and accuracy of machine tool selection optimization were reduced .The algorithm of solving machine tool selection optimization was put forward and designed , based on fuzzy analytic hierarchy process (FAHP) and fuzzy comprehensive assessment (FCA ) .The data were standardized by membership function during the process of assessment standardizing .A case in a machine tool se‐lection optimization of blade tenon milling by an aviation manufacturing enterprises was studied and its feasibility and validity was proved in the machine tool selection optimization .
