多学科设计优化研究应用现状综述

多学科设计优化是一种通过充分探索和利用系统中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。综述了多学科设计优化研究和应用领域的当前进展,并针对多学科设计优化发展的两大难题——计算代价和组织复杂性,介绍了多学科设计优化的主要内容。然后分别介绍了当前处理多学科设计优化的两种方法——试验设计和多学科优化算法。船舶和海洋工程结构物设计也是一个涉及到多个学科的系统工程,然而多学科设计优化的应用却很少,因此实现船舶与海洋工程结构设计的多学科设计优化也必将具有十分广阔的前景。

Overview on Research and Application of Multidisciplinary Design Optimization

Multidisciplinary Design Optimization(MDO) is a methodology for the design of complex engineering systems and subsystems that coherently exploits the synergism of mutually interacting phenomena.This paper presents an overview of the recent developments in the field of MDO.Regarding two challenges of MDO: computational expense and organization complexity,the overview presents the main contents of MDO and introduces two current methods dealing with MDO respectively: experiment design and multidisciplinary design optimization algorithm.Marine structural design is obviously a system engineering of multidisciplinary nature,however its use of MDO is scarce at the moment.It is the authors' belief that the application of MDO in the field of marine structural design is undoubtedly of significant importance.It is hoped that this overview would be of help to those who are interested in the application of MDO.
