摘要
针对传统方法难以对水利水电工程施工安全影响因素重要性进行定量分析的不足,提出了基于粗糙集理论的施工安全影响因素重要性分析方法.该方法利用粗糙集理论在知识挖掘方面的良好性能,从安全评价结果中提取有用信息,对施工安全影响因素的重要性进行定量分析.通过实例说明其对减少分析过程中主观因素影响有很好的效果,为水利水电工程安全施工影响因素重要性分析提供了新的思路.
The importance of safety impact factors in water conservancy and hydropower engineering construction is difficult to quantitatively analyze by traditional methods. In order to overcome this shortcoming, a new method is proposed to analyze the safety impact factors importance, by the useful information extracted from safety assessment results in use of the good knowledge mining performance of rough set theory. The case study shows that the method has a good effect on reducing the influence of subjective factors. It is shown that this new method is suitable for analyzing importance of safety impact factors in water conservancy and hydropower engineering construction.
