Data-Driven Predictive Maintenance: Evaluating ML and DL Models with Enhanced OEE Metrics
摘要
This study introduces a modern solution to predictive maintenance by integrating a Modified Overall Equipment Effectiveness (OEE) framework and comparing the performance of various Machine Learning (ML) and Deep Learning (DL) models. Traditional OEE, based only on Availability (A), Performance (P), and Quality (Q), often provides limited insights, especially in real-time industrial applications. This research incorporates additional parameters. Utilization (U) and Condition (C) to form a more comprehensive Modified OEE, which better reflects machine health and operational efficiency. To support predictive maintenance, models such as Random Forest (RF), XGBoost, Artificial Neural Networks (ANN), and Long Short-Term Memory (LSTM) were evaluated on both sample and real-time datasets. Results indicate that LSTM consistently outperforms other models with the lowest False Negative Rate (FNR = 0) and highest F1 Score (100%) on real-time data. Modified OEE values highlight a more accurate degradation trend compared to traditional OEE, especially during suboptimal machine performance days. This integrated approach not only improves maintenance scheduling but also enhances production reliability and decision-making in Industry 4.0 environments.
