... method and design sensitivity analysis of the confidence level. The probability of the reliability analysis output is obtained with consecutive conditional probabilities of input distribution parameters and input distribution types using a Bayesian approach. The approximate conditional probabilities...

Reliability-Based Design Optimization With Confidence Level for Non-Gaussian Distributions Using Bootstrap Method

Yoojeong Noh, Kyung K. Choi, Ikjin Lee, David Gorsich
Proc. ASME. IDETC-CIE2010, Volume 1: 36th Design Automation Conference, Parts A and B, 1065-1076, August 15–18, 2010

Comparison Study Between Probabilistic and Possibilistic Approach for Problems With Correlated Input and Lack of Input Statistical Information

Ikjin Lee, Kyung K. Choi, Yoojeong Noh
Proc. ASME. IDETC-CIE2009, Volume 5: 35th Design Automation Conference, Parts A and B, 1137-1148, August 30–September 2, 2009
Publisher: American Society of Mechanical Engineers
Paper No: DETC2009-86703
https://doi.org/10.1115/DETC2009-86703
..., two methods for problems with lack of input statistical information — possibility-based design optimization (PBDO) and reliability-based design optimization (RBDO) with confidence level on the input model — are compared using a mathematical example and Abrams roadarm of an M1A1 tank. The comparison...
