摘要
多学科设计优化(Multidisciplinary Design Optimization,简称MDO)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。多学科设计优化算法是其核心部分,也是研究最活跃的领域。文中首先介绍了MDO算法的定义、分类和发展,然后从算法的来源和目的、优化过程、优缺点、改进方法和应用情况等五个方面对四种基于分解技术的MDO算法进行了综述,进而对比了这四种算法的异同点。最后,针对船舶和海洋平台设计的具体特点,归纳了适合于船舶或海洋平台多学科设计优化的MDO算法所需要具备的特征,并建议使用基于近似模型的协同优化算法或BLISS 2000算法进行船舶和海洋平台的多学科设计优化。
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. Due to the obvious shortcomings of the traditional design-spiral approach for both ships and offshore platforms, it leads naturally to the desire to implement MDO techniques. This paper introduces the definition, category and development of MDO algorithm.The latter is the core technique of MDO theory and that is mostly studied.Four mainstream algorithms are elaborated from five aspects: origin, optimization procedure, advantages and disadvantages,other variants and their applications.Then a comparison of them is made. Finally, based on the analysis of the characteristics of the design of ships and offshore platforms, some cru- cial and desirous qualities for an algorithm when implementing MDO are concluded. In addition, two algorithms-collaborative optimization based on approximation models and BLISS 2000 are recommended as suitable methods to apply MDO techniques in the design of ships and offshore platforms.
