杂合灰色聚类与扩展优势粗集的概率决策方法

Probabilistic decision methodology based on hybrid model of grey clustering and extended dominance-based rough set

为了能够由多标准信息表获取最小的知识表达,提出了一种灰色定权聚类与扩展优势粗糙集杂合的方法,杂合方法建立的基本思路为:首先运用灰色定权聚类方法将由不同量纲偏好属性组成的多标准信息表生成多标准决策表,接下来应用扩展优势粗糙集方法进行概率决策分析,并导出偏好概率决策模型.该方法被应用于区域关键技术的评价选择中,获取的偏好概率决策规则可为决策者提供决策参考.

In order to abstract minimal knowledge presentation from multiple criteria information table,a hybrid approach of grey fixed weight clustering and extended dominance-based rough set is proposed.The basic idea of the hybrid method is as follows.Firstly,a multi-criteria information table with different dimensional preferential attributes is transformed into multi-criteria decision table by grey fixed weight clustering approach,then probabilistic decisions are made by means of extended dominance-based rough se...
