摘　　要：灰色决策理论在处理不确定性问题决策中的应用已有不少成果问世,但灰色系统理论与粗糙集理论的整合方法尚不多见.研究在"小样本"、"贫信息"的条件下,利用灰色系统理论与粗糙集理论融合的方法,将决策表进行离散化处理后再进行知识约简,确定极小决策算法.通过对实际工程项目多方案进行综合评价,证明灰色粗糙组合决策方法对处理知识的不确定性和不完全性方面显示出较强的功能,对科学合理决策具有实际指导意义.The grey decision theory has achieved much in dealing with the decision of uncertain problems.However,the method to combine the grey system theory and rough set theory is rather rare.In this paper,the combination of grey system theory and rough set theory is applied to discretizing the decision table and processing knowledge reduction to determine the minimal decision algorithm under the condition of＂small sample＂and＂poor information＂.According to the comprehensive evaluation of several different proposals,it is proved that the grey rough combination decision method has guiding significance in scientific and reasonable decision.
