基于案例分析的语言信息灰靶决策分类模型

针对不确定情形下的分类问题，研究了基于语言案例的多属性决策分类方法.根据灰靶决策过程靶心设置的逆序问题，提出了靶心设置的改进方法；基于自然语言和模糊数的对应关系，提出了语言靶心距测度方法；以案例符合度最大为目标，考虑靶心距分类临界值约束和决策者对指标权重约束，建立了基于模糊靶心距离的分类模型，可以解决语言评价信息下的样本分类问题.算例说明了方法的应用步骤和可行性.

Grey target cluster decision method on linguistic evaluation case-based

The multiple criteria decision making cluster method of linguistic evaluation is suggested under uncertain cluster problem. First, the rule of grey target heart is suggested based on the reversal phenomenon. Second, the target distance is measured based on the transform of linguistic and fuzzy number. Third, the fuzzy distance target cluster decision model is put forward based on object of the maximum case consistency, which stricts to the target cluster rule and the information of criteria weight. The method can solve the cluster problem under linguistic decision-making circumstance. A case study is presented to demonstrate that the procedure can be efficient and effective in practice.
