多种多学科设计优化方法的比较研究

多学科设计优化(Multidisciplinary Design Optimization,MDO)是一种通过充分探索和利用系统间的相互作用的协同机制来设计复杂系统工程和子系统的方法论.随着多学科设计优化方法在船舶与海洋工程中的广泛应用,多学科设计优化方法越来越受到重视,目前已经发展出了多种不同的具体算法.该文的主要目的就是对这些现有的算法开展比较研究,为后续的应用选择奠定基础.论文首先介绍了MDO算法的分类和发展,对各种MDO算法的优缺点进行了比较分析,最后再通过具体算例来显示这些方法的差别.

Comparison of Several Methods for Multidisciplinary Design Optimization

Multidisciplinary Design Optimization (MDO) is a methodology for designing complex systems and subsystems engineering by fully exploring and exploiting the cooperative mechanisms of interaction in the systems.With the extensive application of multidisciplinary design optimization methodsin ship and ocean engineering, the multi-disciplinarydesign optimization method has been received more and more attention.Many different algorithms have been developed. The main purpose of this paper is to carry out a comparative study to these algorithms and lay a good foundation for the selection of an algorithm in the subsequent application. In the paper, the classification and development of MDO algorithms are introduced, and the advantages and disadvantages of MDO algorithms are comparedthrough numerical examples.
