A Review on Local Failure Probability Sensitivity Analysis
Applied Sciences, 2023 When assessing the reliability of a system, a mathematical model is often defined to replicate the system’s behavior. The inputs of the system are then gathered into two categories, random inputs and deterministic inputs.

Reliability-based design using variable-fidelity optimization [PDF]
Structure and Infrastructure Engineering, 2005 Competitive marketplaces have driven the need for simulation-based design optimization to produce efficient and cost-effective designs. However, such design practices typically do not take into account model uncertainties or manufacturing tolerances.

Reliability‐Based Multidisciplinary Design Optimization under Correlated Uncertainties [PDF]
Mathematical Problems in Engineering, 2017 Complex mechanical system is usually composed of several subsystems, which are often coupled with each other. Reliability‐based multidisciplinary design optimization (RBMDO) is an efficient method to design such complex system under uncertainties. However, the present RBMDO methods ignored the correlations between uncertainties.

Interactive Reliability-Based Optimal Design [PDF]
, 1995 Interactive design/optimization of large, complex structural systems is considered. The objective function is assumed to model the expected costs. The constraints are reliability-based and/or related to deterministic code requirements. Solution of this optimization problem is divided in four main tasks, namely finite element analyses, sensitivity ...
