| 摘 要： | 应用多目标优化问题中Pareto最优解集的概念,提出了一种基于多目标遗传算法的直升机总体参数优化设计方法。算法引入了个体的序和密度的概念,改进了变异操作算子,使用精英策略,确保能够搜索到具有较高贴近性、均匀性和完整性的Pareto解集。以UH-1H直升机为优化算例的计算结果表明:多目标遗传算法适用于解决多目标优化问题,能够改善Pareto解的质量和均匀性分布。

| Abstract: | With the Pareto optimal conception in a multi-objective optimization problem( MOP) ,a kind of helicopter preliminary parameter optimization method based on multi-objective genetic algorithm( MOGA) was proposed. The algorithm defined the rank and density of the population,and improved the mutation operator. These strategies had the same purpose for searching a near-optimal,uniformly distributed,and near-complete Pareto front for a given MOP. A UH-1H helicopter was taken as an example,and the solution indicat... |
