| 摘 要： | 基于多目标优化问题Pareto最优解的概念,提出了一种求解非劣解集的多目标遗传算法,重点讨论了算法实现中非劣解集的筛选和适应度的计算.将该算法应用于假想的干线客机方案优化设计,要求巡航段升阻比和有用载荷系数两个目标最大,对优化结果进行了分析比较.研究结果显示出MOGA(Multi-Objective Genetic Algorithms)对飞机方案多目标优化设计具有良好的应用前景.

| Abstract: | Based on the Pareto optimal conception, a kind of MOGA(multi-objective genetic algorithms) seeking non-inferior solution set of MO problems was proposed, while the filtering of non-inferior solutions and the measure of fitness degree were discussed as an emphasis. The algorithm proposed was applied to a two-objective optimization of a hypothetical airliner conceptual design, where both the ratio of lift to drag in cruise segment and the useful load fraction were required to be maximized. The optimal solutions were analyzed and compared to the solution from uni-objective optimization using simple genetic algorithms. The research result demonstrates that MOGA possesses good application foreground for aircraft conceptual multi-objective optimization. |
