一种处理多学科优化问题的通用和有效方法

A General and Efficient Method for Multidisciplinary Design Optimization Problems

提出将多学科设计优化问题按单级优化来处理,并利用包络对偶法直接对其进行优化运算。通过对一道测试和评价多学科优化方法有效性的典型算题的计算和求解,显示了该方法处理多学科优化问题具有收敛速度快、计算效率高、并具有通用性等特点。

In this paper, we propose that the Multidisciplinary Design Optimization （MDO） problem should be formulated as a single-level optimization problem and solved by Enveloped Dual Method. The method is demonstrated on a typical example problem for testing anti evaluating the MDO methods. Results show that the proposed method improves the convergence speed, computational efficiency and applicability of MDO problems.
