Evaluating Artificial Neural Network Robustness for Safety-Critical Systems
Zhang, Jin (Doctoral theses at NTNU;2023:364, Doctoral thesis, 2023)With the power to perform more complex tasks than humans, artificial neural networks (ANNs) have been applied to execute tasks in safety-critical systems (SCSs), such as object detection, image recognition, and navigation. ... -
Failure rates of safety critical equipment based on inventory attributes
Håbrekke, Solfrid; Hauge, Stein; Xie, Lin; Lundteigen, Mary Ann (Chapter, 2018)Reliable failure rate estimates of safety critical equipment is crucial for verifying performance requirements and for trending the safety performance of the equipment. Joint industry efforts, like OREDA, Exida and PDS ... -
Flexible truncation method for the reliability assessment of phased mission systems with repairable components
Lu, Ji-min; Lundteigen, Mary Ann; Liu, Yiliu; Wu, Xiaoyue (Journal article, 2016)Phased-mission systems (PMS) are the system in which the component stresses and the system configuration may change over time. Real-world PMS usually consist of a large number of repetitive phases and repairable components. ... -
Guideline for follow-up of Safety Instrumented Systems (SIS) in the operating phase
Håbrekke, Solfrid; Hauge, Stein; Lundteigen, Mary Ann (Research report, 2023)This guideline describes a best practise for follow-up of safety instrumented systems (SIS) during operation of a process facility. It covers management of functional safety, operation, maintenance, monitoring, and management ... -
