Enhancing Refinery Operations with ADTime
Petroleum refining involves complex, high-dimensional time series data from sensors and product generation. Traditional forecasting models struggle with the unique temporal features and inter-variable dependencies specific to this domain.
Challenge: Accurate prediction of reactant concentrations and generator sensor changes in real-time is crucial for optimizing refinery processes, minimizing waste, and ensuring safety. Existing LLM-based models often fail to capture these domain-specific nuances.
Solution: ADTime's adaptive preprocessing, including channel clustering and selective STL decomposition, allows it to effectively model inter-variable dependencies and diverse temporal patterns. Its temporal alignment and adaptive prompts enhance LLM understanding of domain knowledge.
Result: On real-world refinery datasets (LIMS and PI), ADTime achieved significant improvements, reducing MSE by 17.1% and MAE by 13.5% over state-of-the-art LLM-based methods. This demonstrates ADTime's stronger generalization capabilities and practical applicability in complex, domain-specific industrial forecasting tasks.
