| Metric | LSTM Model | Fourier Model |
|---|---|---|
| Mean Absolute Error (MAE) | 0.0385 | 0.0786 |
| Mean Squared Error (MSE) | 0.1085 | 0.1070 |
| Root Mean Squared Error (RMSE) | 0.3294 | 0.3271 |
| Statistical Significance (p-value) | p < 0.001 (paired t-test, indicating LSTM's superior performance) | |
The LSTM model consistently outperformed the Fourier model across all metrics, with a statistically significant difference in performance. This highlights LSTM's superior ability to capture complex failure dynamics, especially in noisy, non-periodic time-series data, making it more effective for predictive maintenance in industrial settings.
AI in Predictive Maintenance 4.0: Strategic Advantages
Predictive Maintenance 4.0 is transforming industrial operations by integrating AI, machine learning, and IoT to enable proactive rather than reactive maintenance strategies. This shift significantly reduces unplanned downtime, extends asset life, and improves safety and operational efficiency. By leveraging real-time sensor data and advanced analytics, organizations can anticipate potential failures, identify root causes, and optimize maintenance schedules, leading to substantial cost savings and increased productivity.
The integration of advanced analytics allows for the detection of subtle anomalies and degradation patterns that are invisible to traditional monitoring methods, enabling early intervention and preventing catastrophic failures. This intelligent approach ensures maximum machine uptime, better product quality, and enhanced flexibility in production processes, critical for competitive smart manufacturing.
