MULTI-OBJECTIVE FUZZY OPTIMUM DESIGN OF STRUCTURES

摘要

In this paper, on the basis of the former multi-objective ordinary fuzzy optimum design, considering the property of the relative degree in every objective and the influence of the fuzzy constraints. Determine the allowance d_j by using multi-step fuzzy comprehensive judgment At the same time, applying fuzzy sets theory, according to fuzzy decision principles, con-structing judgment function. For the multi-objective fuzzy optimum design of structures, four design methods are presented. Two examples are given in the end.
