摘要/Abstract

摘要：

在两级集成系统协同优化(BLISCO)方法的基础上提出了一种基于近似模型的BLISCO方法,该方法在继承了BLISCO方法优点的同时,具有能够减少设计优化过程中仿真分析和计算次数、平滑设计空间数值噪声、加快收敛速度等优点。通过两个算例,针对子系统存在耦合和不存在耦合两种情况对所提出方法进行了测试,分析结果表明,采用基于近似模型的BLISCO方法可以快速、准确地获得最优解,且综合性能优于原BLICO方法和相关文献所提出的方法。

Abstract:

BLISCO method is a high efficient multi-level MDO method which combines the advantages of Bi-level integrated system synthesis (BLISS) method and collaborative optimization (CO) method. This paper proposed a new BLISCO method based on approximate models. In addition to inheriting the merits of BLISCO method, it can also reduce the number of simulation analysis and calculation during design optimization processes,smooth the numerical noise in design space, avoid local optimum and quickly find the global optimal solution. The proposed method was tested by two examples, separately from both cases of subsystem existing coupling or not. Through the comparative analysis, it shows that the new BLISCO method based on approximate models can obtain the optimal solution quickly and accurately, and its overall performance is better than

that of the original BLISCO method and the methods proposed by the literatures.

Key words: multidisciplinary design optimization, multi-level MDO methods, bi-level integrated system collaborative optimization(BLISCO), approximate model
