RISSaddlepoint Approximation for Sequential Optimization and Reliability Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A good balance between accuracy and efficiency is essential for reliability-based design (RBD). For this reason, sequential-loops formulations combined with the first-order reliability method (FORM) ...
Unified Uncertainty Analysis by the First Order Reliability Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two types of uncertainty exist in engineering. Aleatory uncertainty comes from inherent variations while epistemic uncertainty derives from ignorance or incomplete information. The former is usually ...
Toward Time-Dependent Robustness Metrics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Quality characteristics are often treated as constants in robust design, while many of them actually vary over time. It is desirable to define new robustness metrics for time-dependent quality ...
An Approximation Approach to General Robustness Assessment for Multidisciplinary Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In many engineering applications, both random and interval variables exist. The mixture of both types of variables has been dealt with in robust design for single-disciplinary systems. This work ...
Uncertainty Analysis by Dimension Reduction Integration and Saddlepoint Approximations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Uncertainty analysis, which assesses the impact of the uncertainty of input variables on responses, is an indispensable component in engineering design under uncertainty, such as reliability-based ...
A Second-Order Reliability Method With First-Order Efficiency
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The first-order reliability method (FORM) is efficient but may not be accurate for nonlinear limit-state functions. The second-order reliability method (SORM) is more accurate but less efficient. ...
Time-Dependent Reliability Analysis for Function Generator Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A function generator mechanism links its motion output and motion input with a desired functional relationship. The probability of realizing such functional relationship is the kinematic reliability. ...
Sequential Optimization and Reliability Assessment Method for Efficient Probabilistic Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Probabilistic design, such as reliability-based design and robust design, offers tools for making reliable decisions with the consideration of uncertainty associated with design variables/parameters ...
First Order Reliability Method With Truncated Random Variables
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In many engineering applications, the probability distributions of some random variables are truncated; these truncated distributions are resulted from restricting the domain of other probability ...
An Integrated Framework for Optimization Under Uncertainty Using Inverse Reliability Strategy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, we propose an integrated framework for optimization under uncertainty that can bring both the design objective robustness and the probabilistic design constraints into account. The ...
