| 摘要: |
| 针对BLISS 2000优化过程中权值系数的引入给实际应用带来的困难，提出一种改进的BLISS优化过程——混合BLISS（Hybrid BLISS，HBLISS）。该方法在保持BLISS 2000的基本算法结构的基础上取消权值系数，利用耦合变量的最小残差协调子系统级和系统级优化，给出了HBLISS的算法结构和基本流程。减速器应用算例测试表明了改进的有效性，并在学科自治性和收敛性能方面具有优势。 |

| Abstract: |
| An improved MDO procedure for BLISS 2000 (Bi-Level Integrated System Synthesis 2000), which is named HBLISS (Hybrid BLISS) to find a way out of a difficulty in applications because of the weighting factor, is proposed. The basic algorithm structure of BLISS 2000 was kept and the weighting factor was cancelled, in which the minimum residual error of coupled variables was utilized to coordinate system level optimization and sub-system level optimization. The algorithm structure and flowchart were introduced. The results of Reducer optimization problem show that HBLISS has the superiority in the disciplinary autonomy and convergence, and the improvement is valid. |
