Assessing the completeness of safeguard identification in hazards and operability (HAZOP) studies for oil and gas facilities as a quality metric: An Indonesian case study

Process Safety Progress, Volume 44, Issue 3, Page 379-393, September 2025.
Abstract Qualitative risk assessments, such as hazard and operability studies (HAZOP), are critical for identifying hazards and implementing risk mitigation strategies in industrial processes. One key yet often overlooked measure of HAZOP quality is the completeness of safeguard identification, which can serve as a practical key result indicator (KRI).

Safety Monitoring of Machine Learning Perception Functions: A Survey

Computational Intelligence, Volume 41, Issue 2, April 2025.
ABSTRACT Machine Learning (ML) models, such as deep neural networks, are widely applied in autonomous systems to perform complex perception tasks. New dependability challenges arise when ML predictions are used in safety‐critical applications, like autonomous cars and surgical robots. Thus, the use of fault tolerance mechanisms, such as safety monitors,
