System Reliability Evaluation of a Bridge Structure Based on Multivariate Copulas and the AHP–EW Method That Considers Multiple Failure Criteria

open access: yesApplied Sciences, 2020
The system reliability evaluation of a bridge structure is a complicated problem. Previous studies have commonly used approximate estimation methods, such as the wide bounds method and the narrow bounds method, but neither could obtain an accurate result.

FORM-based global reliability sensitivity analysis of systems with multiple failure modes [PDF]

open access: yesReliability Engineering & System Safety
Global variance-based reliability sensitivity indices arise from a variance decomposition of the indicator function describing the failure event. The first-order indices reflect the main effect of each variable on the variance of the failure event and ...

Inference for One-Shot Devices with Dependent k-Out-of-M Structured Components under Gamma Frailty

open access: yesMathematics, 2021
A device that performs its intended function only once is referred to as a one-shot device. Actual lifetimes of such kind of devices under test cannot be observed, and they are either left-censored or right-censored.
