| 摘 要： | 现实世界中大量存在的信息系统是不完备的,研究了包含不确定性和不精确性两种因素的不完备信息系统,建立了一种基于相似关系推广的粗糙集模型并对这种情况下的不完备决策表进行分析.研究了广义决策约简的方法,根据约简生成了决策规则.

| Abstract: | Incomplete information systems can be found everywhere in the real world. This paper investigates incomplete information system which is composed of uncertainty and imprecision, A generalized rough set model based on similarity relation is established. Then this paper analyses the incomplete decision table on this condition, studies the way of generalized decision reduction and induces accordingly decision rules. |

| Keywords: | incomplete information system similarity relation rough sets knowledge reduction |
