平流层飞艇总体多目标优化设计与决策

将多目标优化与多属性决策相结合应用于平流层飞艇总体多目标优化中。建立平流层飞艇多目标优化模型，实现优化模型参数化建模，采用多目标进化算法NSGA－Ⅱ得到Pareto最优解集，构成多属性决策矩阵，采用模糊熵权TOPSIS（ M－TOPSIS）法对Pareto非劣解进行排序，获得最佳设计方案。最终结果验证了NSGA－Ⅱ平流层飞艇多目标优化中的有效性。

Multi-obj ective Performance Optimization and Decision of Stratosphere Airship

A multi-objective optimization of stratosphere airship is proposed by combining multi -objective optimization and multi-attribute decision making .A multi-objective optimization model is proposed ,a pa-rameterized model for stratosphere airship design is constructed .NSGA-Ⅱmethod is used for multi-ob-jective optimization .The multi-attribute decision matrix is constructed based on the Pareto optimal solu -tions set solved from multi-objective method NSGA-Ⅱ.The modified technique for order preference by similarity to ideal solution ( M-TOPSIS) is employed to rank the Pareto optimal solutions and identify the best Pareto solution .The study demonstrates that the application of the NSGA-Ⅱmethod and M-TOPSIS decision method are effective in stratosphere design optimization .
