摘 要多学科设计优化 ( MDO ) 于 20 世纪 80 年代作为一个新的讨论领域诞生，其主要是对相互影响、相互作用的子系统组成的复杂工程系统进行设计，以使系统的综合性能达到最优的一种设计方法 。它是算法讨论的一个重要应用领域 。在设计优化的过程中，算法选取的好坏直接关系到优化过程的效率和优化结果的准确性 。本文对多学科设计优化领域中涉及的几种智能优化算法的特点进行了总结。在此基础上提出了时间、精度、解决问题的个数等几个比较指标，首次将精度作为比较指标，并且创新性地提出一个针对工程问题的有效比较指标，即短时寻优能力。 首选，对多学科优化机设体系进行了系统的分析讨论，了解和阅读了iSIGHT 方面的有关外文资料，熟悉了 iSIGHT 应用背景、各部分功能、iSIGHT 的优化技术、策略的及掌握 iSIGHT 的使用。 接着，利用 iSIGHT 软件进行案例运行得出数据。对数据结果进行分析，画出坐标图。 最后，利用所学的知识得出比较结果。关键词：智能算法；多学科设计优化；iSIGHTAbstractMultidisciplinary design optimization (MDO) was born as a new research area in 1980s. It is mainly to the mutual influence ， the interaction between subsystems of complex engineering system design， in order to make the system synthesis performance optimum design method. It is one of the important algorithms application fields. In the process of design optimization，algorithm is directly related to select optimal process efficiency and accuracy of the optimization results.This paper summarized characteristics of several intelligent algorithms concerned with multidisciplinary design optimization， and on the basis， put forward several criteria such as time， precision， numbers of problems settled. It was the first time to use the precision as criterion of comparison. This paper originally introduced short-time optimizing capacity to aim at engineering problems. It received a series of instructional conclusions by running the cases selected. The cell phone example validates correctnes...
