- Based on the theory of risk analysis and fuzzy mathematics , three calculation models of fuzzy risk are established and solution is presented . this solution transforms fuzzy variables into random variables by level cut set so that fuzzy risk can be calculated with traditional risk calculation methods
从而运用风险分析理论与相关的模糊数学知识建立了模糊风险的三种计算模型，并提出采用水平截集将模糊变量模糊化处理为非模糊量计算模糊风险的求解方法。 - This paper sets up a fuzzy optimum math - model of the prestressed degree for prestressing bundle disposition of prestressed concrete continuous beam bridges , which is transformed into a clear math program by - level cut - set . by the solution of the clear math program , a succession of reasonable prestressing moments can be obtained . then it is convenient to dispose the prestressing system by only taking account of geometric factors of all controlling sections . based on this , a theory of automatic disposition of the prestressing bundles is proposed and an engineering example is given to demonstrate it
建立预应力混凝土连续梁桥预应力度的模糊优化问题，按-水平截集解法，将模糊优化问题转化为确定性的数学规划问题.求得一较合理的消压弯矩后，只需按控制截面的构造进行预应力体系设计.在此基础上提出了配束自动化的基本思想，并以一实例说明其理论应用 - In the second part , several fuzzy algebra structures , such as l - fuzzy subfield , l - fuzzy linear spaces over l - fuzzy subfields , l - fuzzy algebra over l - fuzzy subfields , l - fuzzy sublattice group etc , are defined . subsequently , based on several kinds of level cut sets in [ 8 ] , their some nature properties are discussed
第二部分的主要内容如下：第二部分这一部分给出了l - fuzzy代数中的l - fuzzy子域， l - fuzzy子域上的l - fuzzy线性空间， l - fuzzy子域上的l - fuzzy代数， l - fuzzy子格群等代数结构的定义并借助于[ 8 ]中的几种水平截集讨论了它们的若干特征性质。 - The method that the fuzzy optimal model is changed to ordinary optimal model by the optimal level cut sets is interpreted . as the model is a mathematical model of multi - objective optimization on minimizing volume and minimizing tooth width , the method that a multi - objective model transformed into a single - objective model is introduced
论文阐述了通过最优水平截集法实现模糊优化模型向常规优化模型转化的方法，由于该模型是一个以体积最小和齿宽最小为优的多目标优化设计模型，论文详细讨论了多目标优化模型向单目标优化模型转化。 - Abstract : this paper sets up a fuzzy optimum math - model of the prestressed degree for prestressing bundle disposition of prestressed concrete continuous beam bridges , which is transformed into a clear math program by - level cut - set . by the solution of the clear math program , a succession of reasonable prestressing moments can be obtained . then it is convenient to dispose the prestressing system by only taking account of geometric factors of all controlling sections . based on this , a theory of automatic disposition of the prestressing bundles is proposed and an engineering example is given to demonstrate it
