Abstract

Diagnostic Bayesian networks (DBNs) offer effective and interpretable solutions for HVAC fault detection and diagnosis (FDD), yet their practical construction and deployment require substantial manual effort. The work proposes a retrieval-augmented LLM framework to achieve robust and automated DBN generation. Preliminary results demonstrate that the proposed framework effectively mitigates hallucinations and significantly improves the structural quality of the generated DBNs.
