摘要
本文提出了结构多目标随机模糊优化设计的概念和实现这一概念的具体方法。为此,本文先定义了对随机模糊约束的满足度,然后建立了对满足度进行运算的模系结构。这种模系运算包含通常的概率运算。此外,还通过合适解集的概念使本方法变得更为合理、简便和易行,有时甚至比单目标最优化还要省时。本文最后给出了如何把该方法应用到抗震结构设计中所需考虑的要点和步骤。
The concept of structural random fuzzy multi-objective optimal design and the concrete method of realizing this concept are given in this paper.Therefore,the satisfaction degrees of the random fuzzy constraints are firstly defined. Then the modular structure which is used for operating these satisfaction degrees is established. This modular operation includes the usual probability operation.In addition, by using the concept of suitable solution, this method becomes more reasonable, simple and practical, and sometimes it even needs less computation time than single-objective optima] design. And finally, the chief points and steps of using this method in aseismic structural random fuzzy optimal design are illustrated.
