基于改进组合赋权法的装配式建筑安全评价研究

Study on the Safety Evaluation of Prefabricated Building Based on Improved Combination Weighting Method

为了提高装配式建筑安全评价的准确性,提出组合赋权法的装配式建筑安全评价方法。构建安全评价指标体系,并采用专家经验法和序列关系分析法进行主观赋权;选用熵值法与标准离差法进行客观赋权,并利用灰关联度改进组合赋权法获取综合权重;根据权值得到装配式建筑的最终安全评价结果。实验结果显示,该方法能够通过组合赋权获取综合权重,获取准确安全评价结果。

In order to improve the safety evaluation accuracy of prefabricated buildings,a safety evaluation method of prefabricated buildings based on combination weighting method is proposed.A safety evaluation index system is constructed,and the subjective weights are given by expert experience method and sequence relationship analysis method.The entropy method and standard deviation method are used for objective weights,and the comprehensive weights are obtained by the improved combination weighting method of grey correlation degree.The final safety evaluation results of prefabricated buildings are obtained according to the weights.The experimental results show that the method can obtain the comprehensive weight through the combination of weights,and obtain accurate safety evaluation results.
