The authors investigate remaining useful life (RUL) estimation with multimodal large language models (MLLMs) grounded through time-series . They propose a framework in which historically similar degradation segments are retrieved from the training set and, together with the test trajectory, transformed into a visual comparison artifact that is processed by the MLLM through a structured multimodal prompt.

They propose a framework in which historically similar degradation segments are retrieved from the training set and, together with the test trajectory, transformed into a visual comparison artifact that is processed by the MLLM through a structured multimodal prompt.
The approach is evaluated on the FD001 partition of the C-MAPSS under repeated experiments comparing -based inference against a non-retrieval baseline based on random reference selection.
The results show that time-series consistently improves MLLM-based RUL prediction across the evaluated models, yielding lower error and more stable performance.
At the same time, the magnitude of the benefit depends on model capacity, indicating that is most effective when the underlying MLLM is able to exploit the retrieved evidence.
The proposed framework has the potential to improve the accuracy and reliability of RUL estimation in various domains, such as aerospace and automotive.
The study also highlights the importance of considering the limitations of MLLM-based RUL estimation and the need for further research in this area.
The results of the study have implications for the development of more accurate and reliable prognostic systems, which can lead to improved maintenance and reduced downtime in various industries.
The study also contributes to the understanding of the role of time-series in improving multimodal prognostic reasoning and highlights the potential of this approach for future research.
The study shows that time-series RAG is a promising mechanism for improving multimodal prognostic reasoning, while also highlighting the current limitations of MLLM-based RUL estimation in practical PHM settings.
