Through practice it has proved that the construction safety risk assessment method is based on the method of quantification, can find out biggest influence factors on the safety of Bridges in engineering, and can also reduce the misjudgment caused by subjective factors. The safety of the bridge has a positive practical significance.展开更多
针对屋顶光伏并网方式无序的问题,构建包含稳定性、经济性和低碳性三个维度的评价指标体系,并设计一种基于模糊层次分析法(fuzzy analytic hierarchy process,FAHP)和改进CRITIC法组合赋权评估模型。由于传统单一赋权法具有一定的偏向性...针对屋顶光伏并网方式无序的问题,构建包含稳定性、经济性和低碳性三个维度的评价指标体系,并设计一种基于模糊层次分析法(fuzzy analytic hierarchy process,FAHP)和改进CRITIC法组合赋权评估模型。由于传统单一赋权法具有一定的偏向性,为此利用FAHP对一级指标进行主观赋权来突显评价目的。同时考虑相关系数的正负以及数据的离散程度,采用熵权法优化的CRITIC算法对二级指标进行客观赋权以增强权重的科学性,进而通过组合赋权得到最终权重。最后以某地屋顶光伏为例设置两组仿真算例,通过5种赋权法分别对指标进行赋权,并采用逼近理想序列算法(technique for order preference by similarity to ideal solution,TOPSIS)进行综合评分。经过对比分析说明了将碳交易和辅助服务收益纳入经济性指标的合理性,以及所提指标体系与评价方法的有效性。展开更多
