摘　　要：切削液是机械加工系统中的重要辅料,切削液不仅影响零件的加工精度、加工效率和加工成本还对环境与卫生有较大的影响。切削液的选择是一个多准则、多目标、多方案的决策问题,考虑到决策者决策的模糊性,文章提出一种指标权重和指标值都是三角模糊数的模糊层次分析法,以切削液的加工性能、理化性能、环境与卫生性能、经济性能为指标建立了切削液选择层次模型,根据三角模糊数的有关理论计算指标权重、指标值得分和可行性方案得分,确定最优方案。最后,以一个连杆螺栓孔加工过程中的切削液选择例,验证该方法的可行性。Cutting fluid is an important part of the machining system,because the improper selection of cutting fluid might cause of many problems affecting negatively on productivity,precision,cost and environment.On the other hand,selecting the optimal cutting fluid among many alternatives is a multi-criteria decision-making （MCDM）problem.Considering the vagueness and uncertainty on judgments of the decisionmaker（s）,in this study a fuzzy analytic hierarchy process with triangle fuzzy number is used to select the best cutting fluid.After the main attributes an sub-attributes for cutting fluid are defined to hierarchy structure,the weights of them and the values of them and the score of alternatives are calculated using fuzzy analytic hierarchy process approach.The cutting fluid with the highest score is selected as the best cutting fluid.Finally,a case study is given to verify the effectiveness and practicability of the method.
