Availability-based engineering resilience metric and its corresponding evaluation methodology
(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 regression based condition monitoring approach for effective reliability prediction of random processes in autonomous energy supply operation
(Journal article; Peer reviewed, 2020)The probabilistic analysis on condition monitoring data has been widely established through the energy supply process to specify the optimum risk remediation program. In such studies, the fluctuations and uncertainties of ... -
A Comparative Study of STPA-Extension and the UFoI-E Method for Safety and Security Co-analysis
(Peer reviewed; Journal article, 2021)Emerging challenges in cyber-physical systems (CPSs) have been encouraging the development of safety and security co-analysis methods. These methods aim at mitigating the new risks associated with the convergence of ... -
Dynamic risk assessment in healthcare based on Bayesian approach
(Journal article; Peer reviewed, 2019)Risks related with healthcare are always dynamic, and they are affected by situations of patients, human errors in treatment and even the states of medical devices. This paper proposes a dynamic medical risk assessment ... -
Group maintenance optimization of subsea Xmas trees with stochastic dependency
(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 ... -
Human reliability analysis: Exploring the intellectual structure of a research field
(Peer reviewed; Journal article, 2020)Humans play a crucial role in modern socio-technical systems. Rooted in reliability engineering, the discipline of Human Reliability Analysis (HRA) has been broadly applied in a variety of domains in order to understand, ... -
Introduction of degradation modeling in qualification of the novel subsea technology
(Journal article; Peer reviewed, 2021)All-electric systems are the novel subsea technology that is an upgrade of widely deployed electro-hydraulic control systems. They promised more reliable equipment and a safer environment. An all-electric production system ... -
Joint optimization of performance-based contracting, condition-based maintenance and spare parts inventory for degrading production systems
(Journal article; Peer reviewed, 2024)As a novel supporting approach, performance-based contracting (PBC) ties the service supplier’s compensation to the performance outcome of the system owned by the customer. It enables the service supplier to implement an ... -
Maintenance analysis of a two-component load-sharing system
(Journal article, 2017)This paper presents a two-component load-sharing system. The failure rates of the two components are time dependent and load dependent. Whenever one fails, it is imperfectly repaired with a time delay during which the ... -
Modeling for evaluation of safety instrumented systems with heterogeneous components
(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 ... -
Multi-phase reliability growth test planning for repairable products sold with a two-dimensional warranty
(Journal article; Peer reviewed, 2019)For products sold with a two-dimensional warranty policy, the warranty servicing cost can be reduced through reliability growth during development. This paper investigates a multi-phase reliability growth test program for ... -
Optimal imperfect maintenance cost analysis of a two-component system with failure interactions
(Journal article; Peer reviewed, 2018)This paper considers a two-component system with failure interactions. Component 1 is repairable and component 2 is non repairable and is subject to an increasing degradation. One considers two different shock models. In ... -
Optimization of maintenances following proof tests for the final element of a safety-instrumented system
(Journal article; Peer reviewed, 2020)Safety-instrumented systems (SISs) have been widely installed to prevent accidental events and mitigate their consequences. Mechanical final elements of SISs often become vulnerable with time due to degradations, but the ... -
Performance analysis for subsea blind shear ram preventers subject to testing strategies
(Journal article; Peer reviewed, 2018)In a subsea blowout preventer system, a subsea blind shear ram preventer (BSRP) plays as a crucial safety barrier by cutting off the drill pipe and sealing the wellhead to prevent serious accidents. Testing and repairs of ... -
Performance analysis of safety barriers against cascading failures in a battery pack
(Peer reviewed; Journal article, 2022)Lithium-ion batteries have been widely employed as the principal power source in electric vehicles and other storage systems. However, some critical issues in a battery pack still exist, such as thermal failures on initial ... -
Performance analysis of safety instrumented systems against cascading failure during prolonged demand
(Peer reviewed; Journal article, 2021)Cascading failures may occur in many technical systems where the failure of one component triggers successive events. Safety barriers like safety instrumented systems are installed in many industries to prevent failures ... -
Proof-testing strategies induced by dangerous detected failures of safety-instrumented systems
(Journal article; Peer reviewed, 2015)Some dangerous failures of safety-instrumented systems (SISs) are detected almost immediately by diagnostic self-testing as dangerous detected (DD) failures, whereas other dangerous failures can only be detected by ... -
Reliability modeling of subsea SISs partial testing subject to delayed restoration
(Journal article; Peer reviewed, 2019)Subsea oil and gas production has always involved the challenging task of determining the overall reliability of safeguarding systems, such as safety instrumented systems (SISs). Partial testing and delayed restoration of ... -
