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

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.
