High-accuracy estimation of physical properties of rubber materials is a critical issue in the advancement of rubber material development. Previous studies have aimed to improve property estimation accuracy by analyzing the effects of external factors (process factors and environmental factors, etc.) on physical properties. These studies have suggested that environmental conditions can have a certain influence on the physical properties of rubber materials. However, the causal relationships among these factors remain unclear. In this study, we apply causal discovery methods to real-world rubber production data to estimate and analyze the relationships between external factors and rubber physical properties in the form of causal graphs. Specifically, we conduct a comprehensive investigation of causal structures across multiple datasets and varying experimental conditions, such as temporal data segmentation and prior knowledge constraints. Experimental results confirm that the estimated causal graphs reveal relationships consistent with empirical knowledge in the real manufacturing site. This study demonstrates that causal-discovery-based analysis can serve as an effective approach for interpreting the relationships between external factors and physical properties in rubber material production process. |
