LMT: A Bayesian Framework for Causal Discovery from Textual Alarm Records in Manufacturing Systems
arXiv:2606.09892v1 Announce Type: new Abstract: Textual event records, such as alarm logs, have become an increasingly common data source in engineering and manufacturing systems. Beyond identifying correlations or recurring patterns, engineers are often interested in understanding which types of events causally trigger or influence other events during system operation. Textual event descriptions may contain semantic clues about such causal relationships, and recent large language models (LLMs) provide a promising tool for extracting these signals. However, relying solely on LLM-encoded textua
The proliferation of textual event data in industrial systems and the advancements in large language models make it timely to explore causal discovery from such data.
Understanding causal relationships in complex manufacturing systems can significantly improve operational efficiency, predictive maintenance, and quality control, reducing downtime and costs.
Traditional correlation-based analyses are being augmented by more sophisticated causal inference methods, driven by AI's ability to process unstructured text.

Improved decision-making and automation for complex industrial processes become possible through clear causal understanding derived from alarm data.
The cost of industrial accidents and system failures decreases as predictive and preventative measures become more effective and precisely targeted.
This could lead to a broader adoption of AI-driven causal inference across other complex systems beyond manufacturing, such as critical infrastructure or logistical networks.
