摘要
考虑到约束条件的模糊性,应用遗传算法和模糊集原理对钢桁架结构进行了优化分析.通过对计算结果的比较和分析,可以得出考虑了结构模糊性的遗传算法对于结构优化设计的优越性,它的优点在于增加了得到整体最优解的可能性,同时,提高了收敛精度,降低了收敛过程中的重复次数,减少了计算时间.
This paper optimizes the steel truss structures by taking into account the fuzziness of constraints and employing GA and the fuzzy set theory. By comparing and analyzing the result, we can see the validity of the fuzzy GA. The advantages of the fuzzy GA include that it can increase likelihood of obtaining the global optimum solution, improve preciseness and reduce the number of iterations of convergence, and reduce total computer processing time.
