由属性值贴近度和阈值λ可构建λ-容差关系,利用此λ-容差关系可定义直觉模糊决策信息系统属性约简的λ-可辨识矩阵,进一步可定义λ-辨识公式,最后通过λ-辨识公式的极小析取范式可以唯一确定直觉模糊决策信息系统所有的相对约简,从而可成功地解决求解直觉模糊决策信解息系统属性约简问题.
The λ-tolerance relationship can be constructed from the closeness of the attribute value and the threshold λ. By using this λ-tolerance relation, the λ-distinguishable matrix of the attribute reduction of the intuitionistic fuzzy decision information system can be defined, and the λ-identification formula can be further defined. Finally, The minimal disjunctive paradigm of λ-identification formula can uniquely identify all the relative reductions in the intuitionistic fuzzy decision information system so that the problem of attribute reduction can be successfully solved for solving the intuitionistic fuzzy decision information system.
