针对传统层次分析法(AHP)在构建刀具优选判断矩阵时没有考虑评价工程师主观判断的模糊性和指标属性的模糊性,导致刀具优选可信度和准确性降低的问题。分析了影响刀具选择的约束因素,建立了一种两级结构的多目标刀具优选模型,包括刀具的加工时间T、加工质量Q、加工成本C、资源消耗R、环境影响E五个优化目标;提出并设计了基于三角模糊数的模糊层次分析法(FAHP)及灰色关联分析(GRA)法进行求解刀具优选层次模型的算法,在三角模糊数互补判断矩阵传统计算权重方法的基础上,进行了算法优化。结合某航空制造企业叶片榫头铣削刀具优化选择的案例,证明了该方法用于刀具优选是可行且有效的。
Aiming at the problem that traditional analytic hierarchy process (AHP) does not consider the fuzziness of subjective judgments and the ambiguity of the index attributes in the construction of the tool selection judgment matrix, which leads to the problem of lower the credibility and accuracy of the cutter preference. The paper analyzes the constraint factors that affect the tool selection and establishes a two - level structure optimization model of multi - target tool, which includes five optimization objectives: tool processing time T, processing quality Q, processing cost C, resource consumption R, and environmental impact E; A fuzzy AHP (Fuzzy Analytic Hierarchy Process) and gray relational analysis (GRA) method based on triangular fuzzy number is proposed and designed to solve the optimal hierarchical model of cutter. Based on the traditional weighting method of triangular fuzzy number complementary judgment matrix, Algorithm optimization. Combined with the case study of blade tenon milling cutter optimization in an aeronautical manufacturing enterprise, it is proved that this method is feasible and effective for tool optimization.
