摘    要:建筑火灾危险度的评价具有评判参数较多、评判结论模糊、评判过程复杂的特点,一般采用模糊数学的方法加以解决,但是模糊数学有一个明显的缺陷就是评价结果为一个向量,而不是一个点值,其结果不够直观,而集值统计方法可以很好地解决此类问题.本文在前期研究中已建立的建筑火灾危险性模糊评价模型的基础上,通过在模糊数学中引入集值统计方法,...

关 键 词:建筑火灾  风险评估模型  模糊数学  隶属函数  集值统计

Abstract:Fuzzy mathematics is appropriate for the situation with many parameters,blurry conclusion and complicated process,so it is increasingly applied to the field of hazard evaluation.But fuzzy mathematics has its disadvantage that the result of evaluation is a vector rather than a point,so it is not intuitive enough.Set-valued statistics is a suitable resolution.In this paper the concept of the subordinate function in fuzzy mathematics and set-valued statistics are combined to build a new model,which modifies interval theory and uses linear interpolation to obtain the quantitative results.The results are more objective and clear,so the model has universal applicability.
Keywords:building fire  risk assessment model  fuzzy mathematics  subordinate function  set-valued statistics
