【摘要】：文章针对风险评估中的不确定信息问题,提出了基于熵AHP和D数理论的方法对洪涝灾害风险进行评估。首先将洪涝灾害风险评估指标体系中的第三级指标用D数表示,同时引入结构熵权法确定相应各级指标的权重,进一步基于D数合成法则给出了各地洪涝灾害风险大小的排序方案,最后通过实例验证了该方法的可行性。
[Abstract]:Aiming at the problem of uncertain information in risk assessment, a method based on entropy AHP and D number theory is proposed to evaluate the risk of flood and waterlogging disaster. First, the third level index in the index system of flood and waterlogging risk assessment is expressed as D number. At the same time, the structure entropy weight method is introduced to determine the weight of the corresponding indexes at all levels, and the ranking scheme of flood hazard risk is given based on the D-number synthesis rule. Finally, the feasibility of the method is verified by an example.
