| 摘 要： | 粗糙决策支持方法是一组用于决策支持的粗糙分析方法,该方法能够充分挖掘决策表的决策能力,以提供强有力的决策支持,并且本质上提供容错的决策支持,条件向量约简是这一方法的重要研究内容。论文以决策强度、条件向量的覆盖度和属性的重要性为启发式信息,提出了条件向量约简的一种启发式算法,通过实验验证了该算法是有效的。

| Abstract: | Rough Decision Support Method(RDSM),which is a family of rough analysis methods for decision support,can make the best use of the decision support abilities of the decision table and provide powerful decision support.RDSM is essentially an error-tolerable method.Condition vectors' reduction is an important aspect of RDSM.In this paper,a heuristic algorithm based on decision strength,the coverage degree of condition vectors and the significance of attribute for condition vectors' reduction is proposed.Experimental results show that this algorithm is effective. |
