基因演算法於結構最佳化設計之應用

Abstract

本文係利用基因演算法來解決結構最佳化設計的問題，也就是在滿足所有 的需求條件之下，尋求斷面積最小之構件，以達到最經濟的效果。 在本 文中，除了介紹基因演算法的原理之外，並實際將基因演算法運用在空間 之椼桿結構及平面之鋼構件結構中，以證明基因演算法應用於結構最佳化 設計的確可達到非常良好的效果 。另外，本文亦對基因演算法的特質及 缺失加以討論，並提出建議 。 This research is according to Genetic Algorithm to solve problems about structure optimization design, that is, to seek for those elements that have smallest area, in order to gain the most economic effect on condition of satisfing all constrains,in this research, we introduce the principles of Genetic Algorithm, and use it in truss and steel structures effectively, to prove that we could have excellent effects in this way, besides we also discuss the characters and disadvan- ages of Genetic Algorithm, and give some suggestions。
