摘要
提出一种基于集对分析理论的结构强度分析方法。此法在随机变量的联系度或联系数中引入了置信度和置信区间 ;在模糊变量的联系度和联系数中引入λ截集以及λ截集区间 ,并且把这些表达式用于结构分析中 ,算例表明 。
An analytical method of structural strength based on a kind of set pair analytical theory is put forward. This method introduced the comfidence degree and region of confidence into relational degree or relational number of random variables, and the λ cut set and λ cut set region are introduced into relational degree and relational number of fuzzy variables,and these expressions are applied to structural analysis. It is indicated by calculational examplew that this method being advanced may be conveniently employed to handle the indeterminate factors in practical engineering.
