摘要
本文在模糊判决原理的基础上,阐述了寻求结构模糊优化问题的特定最优解的限界搜索法,对于具有动、静力约束的油船中剖面进行了模糊优化设计,在模糊约束集中采用两种不同的隶属函数并经规格化处理得到相同的优化解。实例计算表明,使用限界搜索法进行结构模糊优化设计非常简便,且能获得节省材料的效益。
In this paper, the Bound Search Method based on Fuzzy decisionmaking is presented for obtaining the particular optimum solution in fuzzy optimization problems of structures. Fuzzy optimum design of tanker midship section with static and dynamic constraints is then made, in which two different forms of the membership function are adopted in the fuzzy constraints set and the same optimum solution is found by way of the process of scantlings normalization. The illustrative numerical example shows that the fuzzy optimum design of structures using the Bound Search Method is very convenient and is also beneficial for saving materials.
