Application of Digital Twins in Condition-Based Maintenance
Yang, Chao; Cai, Baoping; Shao, Xiaoyan; Liu, Yonghong; Liu, Yiliu; Feng, Qiang; Liu, Guijie; Wang, Honghui (Chapter, 2021)Condition-based Maintenance (CBM) is a combination of fault diagnosis, fault prognosis, and maintenance decisions. The diagnostic results can be used to predict the remaining life and maintenance plans are made based on ... -
Availability-based engineering resilience metric and its corresponding evaluation methodology
Cai, Baoping; Xie, Min; Liu, Yonghong; Liu, Yiliu; Feng, Qiang (Journal article; Peer reviewed, 2018)Several resilience metrics have been proposed for engineering systems (e.g., mechanical engineering, civil engineering, critical infrastructure, etc.); however, they are different from one another. Their difference is ... -
Bayesian network-based risk analysis methodology: A case of atmospheric and vacuum distillation unit
Zhang, Junyan; Cai, Baoping; Mulenga, Kabwe; Liu, Yiliu; Xie, Min (Journal article, 2018)Chemical and petrochemical accidents, such as fires and explosions, do not happen frequently but have considerable consequences. These accidents compromise not only human safety but also cause significant economic losses ... -
Digital Twin-based Prognostics and Health Management for Subsea systems: Concepts, Classification, Opportunities and Challenges
Abbas, Mohsin; Liu, Yiliu; Cai, Baoping (Chapter, 2021)Digital Twin (DT) constitutes to be an important pillar for industrial transformation to digitalization. Both academics and industries have recently started the exploration on methodologies and techniques related to DT. A ... -
Group maintenance optimization of subsea Xmas trees with stochastic dependency
Fan, Dongming; Zhang, Aibo; Feng, Qiang; Cai, Baoping; Liu, Yiliu; Ren, Yi (Peer reviewed; Journal article, 2021)Subsea Xmas trees (XTs) are vital equipment for offshore oil and gas development. Due to a long and continuous operation, components of XTs often become vulnerable subjected to degradation and unexpected failures. Due to ... -
A hybrid multi-stage methodology for remaining useful life prediction of control system: Subsea Christmas tree as a case study
Liu, Xuelin; Cai, Baoping; Yuan, Xiaobing; Shao, Xiaoyan; Liu, Yiliu; Khan, Javed Akbar; Fan, Hongyan; Liu, Yonghong; Liu, Zengkai; Liu, Guijie (Peer reviewed; Journal article, 2023)With the improvement of control system composition and operation process complexity, the uncertainty in its operation process increases and real-time observation data is difficult to obtain, and the influence of noise also ... -
Modeling for evaluation of safety instrumented systems with heterogeneous components
Cai, Baoping; Li, Wenchao; Liu, Yiliu; Shao, Xiaoyan; Zhang, Yanping; Zhao, Yi; Liu, Zengkai; Ji, Renjie; Liu, Yonghong (Peer reviewed; Journal article, 2021)A novel methodology for evaluation of safety instrumented systems (SISs) with heterogeneous components based on multi-stage dynamic Bayesian networks (MDBNs) is proposed. The unified evaluation model for M-out-of-N ...
