基于层次分析法的建筑火灾灾后评估方法研究

Study on building fire post-disaster assessment based on analytic hierarchy process

由于建筑火灾影响的复杂性和多样性,导致灾后评估结果较为主观片面,不够准确。针对上述问题,提出基于层次分析法的建筑火灾灾后评估方法研究。通过收集火灾现场的资料,了解火灾的基本情况。引入层次分析法,构建灾后评估指标体系,通过比较不同因素之间的相对重要性度,建立权重关系,确定各因素对整体的影响程度,实现对建筑火灾灾后的评估。实验结果表明,层次分析法能够综合考虑火灾影响的各个方面,全面评估火灾损失和影响程度,能够提供更加客观、逻辑清晰的评估结论。

Due to the complexity and diversity of the impact of building fire,resulting in the post-disaster assessment results more subjective and one-sided issues are not accurate.In order to solve these problems,a method of building fire post-assessment based on analytic hierarchy process (AHP) is proposed.First of all,through the collection of fire site information,to understand the basic situation of the fire.Secondly,the AHP is used to construct the post-disaster evaluation index system.By comparing the relative importance of different factors,the establishment of the weight is to determine the impact of various factors on the overall degree of building fire to achieve the post-assessment.The experimental results show that the AHP can comprehensively consider all aspects of the loudest fire,comprehensively assess the fire loss and impact,and provide more objective and logical conclusions.
