复杂耦合系统新兴的多学科设计优化方法

针对传统的复杂系统设计与工程设计领域中,设计方法或者优化方法是顺序地或者没有充分考虑子学科或子系统之间的交互作用与耦合关系的弊病,介绍了多学科设计优化方法(Multidisciplinary Design Optimization——MDO)在解决航天器设计复杂系统工程中的有效成就;接着介绍MDO的思想和研究内容,单级优化和两级优化的典型方法,然后叙述了目前国内外的研究成果和进展,充分表明其在解决此类复杂系统上的优势和研究价值;展望了多学科设计优化方法在所有此类复杂设计与工程领域重大研究价值的前景。

Multidisciplinary Design Optimization of Complex Coupled System

In traditional method of designing complex system and engineering, the design method is sequential or lack of considering the coupling relations of the subdisciplines or subsystems. Because of the defects above, the achievements of Multidisciplinary Design Optimization (MDO) way is introduced to be used in aerospace field, then by simply surveying typical mathematical models and algorithms of MDO and introducing its research progress, it can be seen that its advantages is obviosly when used in such complex ...
