Moreover, when accounting for uncertainties in the manufacturing process, material properties, and loading conditions, the process of reliability-based design optimization (RBDO) for complex engineering systems necessitates the repeated execution of expensive tasks throughout the optimization...

...Wanxin He; Hua Yang; Gang Zhao; Yan Zeng; Gang Li Reliability-based design optimization (RBDO) is receiving more attention from researchers because it can help to minimize cost reasonably in practical engineering. A large number of methods have been proposed to solve RBDO problems, most of which...

...Yutian Wang; Peng Hao; Zhendong Guo; Dachuan Liu; Qiang Gao The expensive computational cost is always a major concern for reliability-based design optimization (RBDO) of complex problems. The performance of RBDO can be lowered by the inaccuracy of reliability analysis (RA) which is caused...

...Sangjune Bae; Nam H. Kim; Seung-gyo Jang This paper presents a tradeoff between shifting design and controlling sampling uncertainty in system reliability-based design optimization (RBDO) using the Bayesian network. The sampling uncertainty is caused by a finite number of samples used...

...Meng Li; Mohammadkazem Sadoughi; Chao Hu; Zhen Hu; Amin Toghi Eshghi; Soobum Lee Reliability-based design optimization (RBDO) aims at optimizing the design of an engineered system to minimize the design cost while satisfying reliability requirements. However, it is challenging to perform RBDO under...

Choi; Ikjin Lee; David Gorsich; David Lamb For reliability-based design optimization (RBDO), generating an input statistical model with confidence level has been recently proposed to offset inaccurate estimation of the input statistical model with Gaussian distributions...

...Dong-Shin Lin; Chun-Min Ho; Kuei-Yuan Chan In this research, we investigate design optimization under uncertainties for problems with two objectives. Reliability-based design optimization (RBDO) that considers uncertainties as random variables and/or parameters and formulates constraints...

...Kai-Shian Hsu; Kuei-Yuan Chan In this work, we develop a filter-based sequential quadratic programming (SQP) algorithm for solving reliability-based design optimization (RBDO) problems with highly nonlinear constraints. The proposed filter-based SQP uses the approach of average importance sampling...
