基于几何规划的稳健设计

Robust Designs via Geometric Programming

Ali Saab, Edward Burnell, Warren W. Hoburg

摘要:

提出了鲁棒几何规划(RGP)作为凸规划的一种近似形式。使用几何规划(GP)来建模复杂的工程系统的兴趣一直在增长,这激发了明确建模的不确定性基本的工程设计优化。RGP提供了一个框架来建模和求解GP,同时将其不确定性表示为属于不确定性集。这里提出的RGP方法是基于重新制定的GP,然后鲁棒的方法,从强大的线性规划。这些新的方法,以及以前的文献中,被用来robustify两个飞机设计问题,这些不同的方法的结果进行了比较和讨论。

英文摘要:

An approximate formulation of a robust geometric program (RGP) as a convex program is proposed. Interest in using geometric programs (GPs) to model complex engineering systems has been growing, and this has motivated explicitly modeling the uncertainties fundamental to engineering design optimization. RGPs provide a framework for modeling and solving GPs while representing their uncertainties as belonging to an uncertainty set. The RGP methodologies presented here are based on reformulating the GP and then robustifying it with methods from robust linear programming. These new methodologies, along with previous ones from the literature, are used to robustify two aircraft design problems, and the results of these different methodologies are compared and discussed.
