| 摘 要： | 排水管路运行风险的实时评估对于提高管路风险预测十分有必要。介绍了Semi-Naive—Sealer属性离散化算法，给出了基于可辨识矩阵的属性约简算法，并采用了基于可辨识矩阵的二值化数据过滤和贪心算法相结合的规则约简算法。通过属性约简和规则约筒，得出决策规则。最后在排水管路运行风险评估方面给出了应用算例。

| Abstract: | It is necessary to run a real time risk assessment for improving the prediction of drainpipe lines risk level . this paper introduces the attribute discretization algorithm of the Semi-Naive--Scaler, gives attributes reducing algorithm based on discernibility matrix, and also adopts the rules reducing algorithm combined with binarization data filtration based on discernibility matrix and greedy algorithm. Through attribute reduction and rule reduction, it obtains decision rules. Finally, an application example in risk assessment of drainpipe lines running is given. |
