文献都是用模糊方法评判磨削液的,在做模糊关系运算时,文献用的是普通矩阵运算规则,这种运算没有封闭性,不符合模糊逻辑;文献用的是Zadeh算子,Zadeh运算要丢掉一部分信息,因而有评判失效的可能。近年来出现的其它模糊算子也都各有优缺点,在具体评判中如何选择合适的算子是一个急待解决的问题,有鉴于此,作者提出了下文所述的新方法。1 模糊关系的建立 设有n种待评磨削液,每种磨削液有m个评价指标。令: U=ui| ui代表第i种磨削液,i=1,2,…,n, V=vj| vj代表评判水平,j=1,2, A=ak|ak代表第k个评价指标的实验值,k= 1,…, m,
In the literature, the fuzzy method is used to judge the grinding fluid. In the process of fuzzy relational operation, the literature uses ordinary matrix operation rules, which are not closed and do not conform to fuzzy logic. The literature uses Zadeh operators, Zadeh operations To lose some of the information, which may be judged invalid. In recent years, other fuzzy operators also have their own advantages and disadvantages, and how to select the appropriate operator in a concrete judgment is an urgent problem to be solved. In view of this, the authors propose the new method described below. A fuzzy relationship with the establishment of n kinds of pending grinding fluid, m each grinding fluid evaluation index. Let: u = ui | ui represents the ith grinding fluid, i = 1,2, ..., n, V = vj | vj represents the judgment level, j = 1,2, A = ak | ak represents the kth evaluation The experimental value of the indicator, k = 1, ..., m,
