RISSystem Reliability-Based Design Optimization Under Tradeoff Between Reduction of Sampling Uncertainty and Design Shift
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
Estimating Effect of Additional Sample on Uncertainty Reduction in Reliability Analysis Using Gaussian Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An approach is proposed to quantify the uncertainty in probability of failure using a Gaussian process (GP) and to estimate uncertainty change before actually adding samples to GP. The approach estimates the coefficient ...
