结构模糊最优设计的对分法和直接规划法

HALF-AND-HALF METHOD AND DIRECT PROGRAMMING METHOD ABOUT FUZZY OPTIMUM DESIGN OF STRUCTURES

摘要: 本文根据Bellman-Zadeh模糊判决原理,提出了结构模糊最优设计的两种解法:对分法和直接规划法。前者一般只用2次迭代,后者转为直接规划即可确定最优水平α^* ,计算简捷,结果相同。

Abstract: Based on Bellman-Zadeh's fuzzy decision principle, two methods about fuzzy optimum design of structures (half-and-half method and direct programming method) are presented in this paper. The former usually needs two iterations, the letter turns the problen into a direct programming, then the optimum level is cletermined. The results of two methods are identical.
