摘要
本文提出在设计风速一次作用下,发生破坏概率最小,并结构物重量最轻的双目标优化思想.并构造了一个含有这二个目标值的替代函数.使上述矢量优化问题转化为一个替代的无约束优化问题来解决.其优点在于省时,方便.结构破坏概率不作为约束条件而作为目标提出,不必事先定出约束的边界,节省准备时间.其次,计算时无须每步判别是否满足约束条件,正大大地节省机时.
In this paper, a fundamental idea of vector optimization with two goals is presented for making the damage probability of the structure minimum and the weight of the structure lightest. A substitutional function to meet the both goals is used in order to solve this problem. It transformes this vector optimization problem into a substitutional scale unbinding optimization. The advantages of the method are convenience and saving the computation time.
