| 摘 要： | 粗集和软集在解决不确定的问题的决策分析过程中,属性约简是关键和棘手的问题.与粗集理论相比较,利用软集方法能够有效地简化决策过程.决策信息系统用软集形式表示,用软集处理粗集理论中的等价关系,进行有效的属性约简,给出一个属性真度的概念作为反映条件属性重要性的函数,在此基础上给出一种适合软集属性约简的启发式算法,通过分析和实例证明该软集属性约简方法,简化约简过程,降低运算的复杂度. |
| 关 键 词： | 软集 决策系统 属性真度 属性约简 |

| Abstract: | The attribute reduction of rough sets and soft sets theory is one of the key and difficult problem to deal with the problems of uncertain in the decision making analysis.Compared with the rough sets theory,decision making process has effectively simplified by using the method of soft sets.The decision information system is represented soft sets,soft sets are used to process equivalence relation of rough sets and give attribute reduction efficiently.Considered as the importance function of condition attribut... |
| Keywords: | soft sets decision information system attribute truth degree attribute reduction |
