三角模糊数在水电工程风险识别中的应用

为实现风险因素识别的数量化和科学化、提高风险识别的效果,基于水电工程特点,提出在风险因素识别中引入三角模糊数法进行量化研究,构建了施工过程中风险评价指标体系,计算了三角模糊数风险判断矩阵的期望值,并对互补判断矩阵进行排序进而获得风险指标权重.计算结果表明,该方法可实现识别水电工程中存在的风险.

Application of Triangular Fuzzy Number to Hydropower Project Risk Identification

In order to identify the risk factors quantitatively and scientifically and improve risk identification effect, the triangular fuzzy number method is introduced to quantitatively study risk identification by analyzing the characteristics of hydropower project. And then the risk evaluation index system in construction process is established and the expected value of triangular fuzzy number risk judgment matrix is calculated. Finally, it ranks the complementary judgement matrix to obtain the risk indicator weights. The results show that the proposed method can achieve the hydropower project risk identification.
