【摘要】 介绍了多学科设计优化计算过程中存在的不确定性问题以及不确定性对设计过程和设计结果的影响。另外,采用在多学科设计优化流程中加入可靠性和稳健性分析模块来保证结果的可靠与稳健,用实验设计方法和6σ方法控制设计变量,保证设计过程的稳定收敛。更多还原

【Abstract】 The uncertainty in the multidisci-plinary design optimization process and the effects of the uncertainty on design process and design result are introduced. The reliability and stability of the results can be ensured by adding the analysis module of reliability and stability in the multidisciplinary design optimization flow, and the design variables can be controlled by using DOE (design of experiment) method and 6a method to guarantee the stable convergence in the design process.更多还原
