摘要
提出一种用于多决策属性和决策属性可能取空值的不确定决策系统规则提取的粗糙集方法,并给出了求其广义决策函数的算法.
It puts forward a rough set method for the rule extraction in the indefinite decision system that could have multiple decision attributes and enable decision attributes to have absent value. The algorithm for the general decision function is also given.
