一种不完全信息下的决策规则获取方法

An Approach of Obtaining Decision Rules with Incomplete Information

针对含有模糊属性值的多属性群决策问题,提出了一种模糊属性值区间的确定方法。首先将属性划分成准则、定性属性、定量属性三类,分析了不同属性类型下不同方案之间的关系;同时分析了不同截集下决策规则的分类性质,给出了依据分类质量确定模糊属性区间的分析方法;并运用算例演示了该方法的可行性和有效性。

A new approach of fixing on the interval of fuzzy attribute value is proposed for the multi-attribute group decision problem including fuzzy attribute value.Firstlyattributes can be divided into three types criteriaqualitative attributesand quantitative attributes.We analyze the relationship among different alternatives in different types of attributes.Secondly the classification property of decision rules under different cutting points is analyzed and the approach of fixing on the interval of fuzzy attribute value by classification quality is put forward. At last we give a calculation example to validate the feasibility and validity of the new approach.
