摘要
本文基于各种模糊判决原理及贴近度择近原则,就单目标结构的模糊优化设计,对综合模糊目标集F和模糊约束集c的模糊判决集D构造不同的判决函数,从而形成不同的方法,得出不同意义下的模糊最优解。文中以船舶结构的两个实例加以说明。
For the single objective fuzzy optimum design of structures, based on the principles of the fuzzy decision-making and the principle of the nearness maximization,the different decision functions which belong to the fuzzy decision sets synthesizing the fuzzy objective set and the fuzzy constraint set are constructed. Thus,the different methods are put forward, and the fuzzy optimum solutions in different meanings are found. Two numerical examples in ship structures are given in the paper.
