基于多目标遗传算法的飞行甲板参数化设计优化方法

摘要

The design of the flight deck layout is a critical and difficult point in the general design of air⁃craft carriers,and the optimization of which significantly improves the deck arrangement,and sortie gener⁃ation capacity of aircrafts. To reduce the complexity and diversity of the flight deck design process,a para⁃metric modeling approach is proposed,and the relation between the flight deck layout and the various char⁃acteristic parameters is established. Also,multi-objective genetic algorithm is presented based on the mathematic and optimization model of the flight deck design. The result shows that parametric optimization approach is able to efficiently transform the complex design process to the optimization of a few parameters affecting the performance of the flight deck,and the optimal solution set can be then obtained through the multi-objective genetic algorithm.%　　飞行甲板是航母总体设计的关键和难点，开展飞行甲板设计优化对提高航母的甲板布列、舰载机的出动回收能力等总体设计具有重要意义。为解决飞行甲板设计变量、评估要素众多而带来的总体设计的复杂性和多样性，提出一种全参数化的飞行甲板建模方法，并采用多目标遗传算法，建立飞行甲板多目标设计优化的数学模型和算法。研究表明：飞行甲板参数化模型可准确构建飞行甲板的外形方案，结合多目标遗传算法可有效实现飞行甲板多方案的自动评估和优化，获得多目标优化的前沿解。
