Failures of engineered systems can lead to significant economic and societal losses. Despite tremendous efforts (e.g., $200 billion annually) denoted to reliability and maintenance, unexpected catastrophic failures still occurs. To minimize the losses, most engineered systems are designed through system reliability-based design optimization (RBDO) and/or with high system redundancies. However, a high level of system redundancy increases a system’s life-cycle cost (LCC) and system RBDO cannot ensure the system reliability when unexpected loading/environmental conditions are applied. In contrast, a new design paradigm, referred to as resilience-driven system design, can ensure highly reliable system designs under any loading/environmental conditions while considerably reducing systems’ LCCs. In order to advance this design paradigm, this research advances two essential research areas: Thrust 1 – system RBDO and Thrust 2 – system prognostics and health management (PHM). In Thrust 1, reliability analyses under uncertainty will be carried out in both component and system levels against critical failure mechanisms. Thrust 2 aims at designing highly confident PHM systems for engineered systems. To demonstrate the effectiveness of the proposed RBDO and PHM techniques, multiple engineering case studies will be presented and discussed.


Mr. Chao Hu received his B.E. degree in Engineering Physics from Tsinghua University in Beijing, China in 2003. He is currently a Ph.D. candidate in the Mechanical Engineering Department at the University of Maryland, College Park in USA. His research interests are system reliability analysis, prognostics and health management (PHM), and battery power and health management of Li-ion battery system.
