摘要
提出一种基于粗糙集理论的输电线路状态评估方法。利用粗糙集理论建立决策表,采用基于可辨识矩阵的属性约简算法对决策表进行约简,得到决策规则,并研究了条件属性的重要度,最后给出实例验证。结果表明,该方法能够有效地约简规则,评估结果合理。
The paper proposes a status evaluation method of transmission lines based on rough set. The method establishes decision table by rough set and adopts attributes reduction approach based on recognizable matrix for decision table reduction. Decision rules are concluded, importance of conditional attribute is studied, and finally example verification is given. The result shows that the method is effective in rules reduction and the evaluation result is reasonable.
