Trust at Your Own Peril: A Mixed Methods Exploration of the Ability of Large Language Models to Generate Expert‐Like Systems Engineering Artifacts and a Characterization of Failure Modes

Systems Engineering, Volume 28, Issue 5, Page 583-604, September 2025.
ABSTRACT Multi‐purpose large language models (LLMs), a subset of generative artificial intelligence (AI), have recently made significant progress. While expectations for LLMs to assist systems engineering (SE) tasks are paramount; the interdisciplinary and complex nature of systems, along with the need to synthesize deep‐domain knowledge and ...

Availability Evaluation of Overhead Contact Lines Based on a Stochastic Colored Petri Nets Model

IET Electrical Systems in Transportation, Volume 2025, Issue 1, 2025.
Due to their nonbackup characteristics and constant exposure to outdoor conditions, the performance of overhead contact lines (OCLs) will gradually degrade over time and further result in equipment defects or frequent failures. These issues significantly impact system availability and incur substantial repair costs.

Performance Criteria Assessment of Marine Radionavigation Systems Reliability Under Degradation Factors

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
This study presents a dual‐component reliability model for marine radionavigation systems, accounting for both gradual degradation and sudden failures under harsh maritime conditions. The approach integrates failure rate estimation, MTBF analysis and scenario‐based simulation to predict critical operational thresholds and optimise maintenance planning.
