Abstract System safety, reliability and risk analysis are important tasks that are performed
throughout the system life-cycle to ensure the dependability of safety-critical systems …

Safety barriers include physical and non-physical means in different industries for
preventing the occurrences of hazardous events and mitigating the consequences in case …

Fault diagnosis is useful in helping technicians detect, isolate, and identify faults, and
troubleshoot. Bayesian network (BN) is a probabilistic graphical model that effectively deals …

The Bayesian network (BN) is a powerful model for probabilistic knowledge representation
and inference and is increasingly used in the field of reliability evaluation. This paper …

Bayesian network (BN) is a commonly used tool in probabilistic reasoning of uncertainty in
industrial processes, but it requires modeling of large and complex systems, in situations …

Transient fault (TF) and intermittent fault (IF) of complex electronic systems are difficult to
diagnose. As the performance of electronic products degrades over time, the results of fault …

The selection of variational mode decomposition (VMD) parameters usually adopts the
empirical method, trial-and-error method, or single-objective optimization method. The …

Deepwater oil and gas equipment is a complex and dynamic system that requires thorough
risk assessment during its operation. Existing methods such as fault tree analysis, failure …

This paper proposes a methodology to evaluate system operational reliability. The dynamic
Bayesian network (DBN) and XGBoost are integrated within an evaluation framework. The …

The coupling of multiple factors stemming from propagation effects and interdependency
relationships among risks is prone to generate major accidents. It is of necessity to develop …
