RISMulti-Target-Reliability-Based Design Optimization: A New RBDO Method Considering Multiple Target Reliabilities Simultaneously
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Traditional reliability-based design optimization (RBDO) methods are typically developed to address problems with a single-target reliability. However, as the complexity of engineering structures increases, there ...
Reliability Analysis Considering Model Uncertainty Based on Adaptive Expectation Maximization-Enhanced Stochastic Polynomial Chaos Expansion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Model uncertainty exists in stochastic simulators, which provides different responses when evaluated repeatedly, even with fixed input values. It is prevalent in multiple engineering fields, but research regarding ...
Surrogate-Based Time-Dependent Reliability Analysis for a Digital Twin
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mature digital twin (DT) is supposed to enable engineers to accurately evaluate the real-time reliability of a complex engineering system. However, in practical engineering problems, reliability analysis (RA) often ...
