Reliability Engineering & System Safety

• Proposal of a performance indicator based on the ratio of vulnerabilities associated with two different assets. • Inclusion of stochastic surrogate models for the derivation of non-log-normal fragility surfaces. • Seismic assessment of the out-of-plane behavior of slender multi-span MABs considering flood-related hazard uncertainties Railway networks are highly centralized and operate as series…

Data from psychophysiological measures can offer new insight into control room operators’ behaviour, cognition, and mental workload status. This is particularly helpful when assessing capacity to respond to critical plant conditions such as alarm response scenarios. However, wearable tools such as eye tracking and electroencephalography caps can be perceived as intrusive and unsuitable for daily …

Large Language Models (LLMs) are increasingly deployed across diverse domains, raising the need for rigorous reliability assessment methods. Existing benchmark-based evaluations primarily offer descriptive statistics of model accuracy over datasets, providing limited insight into the probabilistic behavior of LLMs under real operational conditions. This paper introduces HIP-LLM, a Hierarchical Im…
