Research
Active Learning for Structural Reliability
We focus on enhancing the reliability assessment of engineering structures through advanced active learning techniques. The framework integrates various methods, such as, surrogate modeling, Monte Carlo simulation, and adaptive learning. Surrogate models such as kriging and polynomial chaos expansions are employed to efficiently approximate the limit-state surface, making the exploration of the random space more cost-effective. Reliability methods, including Monte Carlo simulations, are utilized to estimate failure probabilities with high accuracy, contributing to the development of safer and more reliable structural designs.
Quantum Computing for Reliability Simulation
We explore the application of quantum computing to reliability engineering by developing quantum algorithms to address complex reliability problems, including the use of quantum fault trees. Our goal is to leverage the unique capabilities of quantum computing to solve reliability challenges that are intractable with classical methods. By advancing computational power, we aim to enhance system reliability assessments, life data analysis, and reliability simulations, paving the way for more robust and efficient engineering solutions for the future.
Reliability Analysis of Complex Systems
Our research focuses on the reliability, life prediction, and health management of complex engineering systems. We develop dynamic reliability analysis methods and data-driven models using Bayesian networks and machine learning for health monitoring, fault detection, and remaining useful life prediction. By integrating advanced predictive algorithms, quantum-classical hybrid techniques, and real-time condition monitoring data, we enable proactive failure identification and system optimization. This work supports reliability-based design, predictive maintenance strategies, and overall performance improvement, reducing downtime and ensuring operational efficiency in a variety of challenging environments.
Bayesian Degradation Modeling and Prediction
We develop advanced likelihood-free algorithms for Bayesian degradation modeling and reliability prediction, focusing on model selection and parameter estimation from noisy and limited condition monitoring data. Our expertise includes Hamiltonian Monte Carlo-based and subset simulation-based algorithms, applied to stochastic degradation modeling and prediction. By incorporating randomness and uncertainty, we try to simulate degradation processes over time, enabling life prediction and reliability assessment. These methods guide maintenance strategies, optimize resource allocation, and enhance safety, ensuring the structural integrity of engineering systems under uncertain conditions.
