With the advancement of modern industry towards high-end and intelligent development, highly reliable components and systems have become the cornerstone of national strategic and critical infrastructure fields such as aerospace, energy and power, rail transportation, and national defense. Their performance and lifespan face severe challenges from multiple uncertainties, including complex multiphysics coupling, manufacturing tolerances, material degradation, time-varying loads, and environmental disturbances. Traditional strategies based on single-physics fields, deterministic assumptions, and fixed-period maintenance encounter significant bottlenecks in accurately characterizing failure mechanisms, quantifying lifecycle risks, and achieving proactive health management.

In recent years, interdisciplinary approaches integrating multiphysics modeling and simulation, uncertainty quantification theory, and data-driven artificial intelligence have provided revolutionary pathways to address these challenges. By constructing digital twins for components and systems that integrate physical mechanisms and uncertainties, the cross-scale correlation from microscopic failure to system-level performance degradation can be deeply revealed. Employing advanced uncertainty quantification techniques enables probabilistic and accurate assessment of reliability boundaries and remaining useful life distribution. Furthermore, combining intelligent algorithms such as machine learning and deep learning empowers real-time condition perception, early fault diagnosis, and autonomous optimization of predictive maintenance decisions, thereby achieving comprehensive improvement in reliability, safety, and cost-effectiveness throughout the entire chain of design, manufacturing, operation, and maintenance.

This Special Session aims to gather cutting-edge research and innovative practices from academia and industry in related areas. It focuses on leveraging key technologies such as multiphysics modeling, uncertainty quantification, and intelligent health management to systematically address the core challenges in the reliability design, assessment, prediction, and operational management of highly reliable components and systems. The session seeks to promote the deep integration of methodological innovation and engineering application in this field. Topics of interest include, but are not limited to: Multiphyics Coupling Modeling and Simulation Verification for Highly Reliable Components and Systems; Characterization of Uncertainty Sources, Propagation Analysis, and Sensitivity Studies; Reliability Robust Design and Multi-objective Optimization; Research on Failure Mechanisms, Diagnostic Algorithms, and Remaining Useful Life Prediction Techniques; Digital Twin-Driven or Data-Fusion Intelligent Health Management Frameworks and Systems; Relevant Advanced Experimental Methods and Significant Engineering Application Cases.
