基于熵权物元的输变电工程安全评价模型及应用
|
摘要
针对输变电施工过程中的复杂性和多变性,在输变电工程安全性评价中引入了熵权法与物元可拓模型相结合的评价方法.根据输变电工程特征及实际施工情况,建立了输变电工程安全评价的指标体系,采用改进的熵权法计算各指标权重以避免出现熵值无意义的情况,并运用物元分析法处理评价模型中的模糊性.最后以某输变电工程为实例进行计算分析,验证了所建模型的正确性、可行性和实用性.
Aimed at the complexity and variability of power transmission in the process of construction, the evaluation method which is the combination of entropy method and the matter-element extension model was introduced in the safety evaluation of power transmission project. According to the characteristics of engineering and the actual construction situation,the index system of safety evaluation of power transmission project was established. The improved entropy weight method was used to calculate the weight of each index in order to avoid the fact that the entropy is meaningless, and the matter-element analysis method was used to deal with the fuzziness in the evaluation model. Finally a power transmission project as an example for calculation and analysis, the model is verified the correctness, feasibility and practicability.
