Abstract	Industrial organizations increasingly depend on complex production equipment whose unexpected failure can disrupt output, increase maintenance expenditure, reduce asset availability, and compromise operational reliability. Predictive analytics provides a data-centered approach to maintenance by transforming equipment-condition information into estimates of degradation, abnormal behavior, failure probability, and remaining useful life. This study examines how predictive analytics can strengthen industrial maintenance decision-making and improve operational reliability by integrating condition-monitoring data, machine-learning techniques, anomaly detection, and risk-based maintenance prioritization. A simulation-based analytical design was adopted because verified plant-level operational data were not available for the present study. A synthetic industrial asset environment representing motors, pumps, compressors, and gearbox systems was constructed to compare reactive, preventive, and predictive-analytics-driven maintenance strategies. The analytical framework evaluated unplanned downtime, asset availability, mean time between failures, maintenance-cost efficiency, and maintenance intervention effectiveness. The simulated comparison indicates that predictive analytics can produce substantial operational benefits when it is supported by reliable sensor data, appropriate model validation, maintenance-domain expertise, and integration with existing maintenance-management systems. In the illustrative scenario, unplanned downtime declined from 32 hours under reactive maintenance and 21 hours under preventive maintenance to 11 hours under predictive analytics for every 1,000 operating hours. Predictive maintenance also produced the highest simulated availability and mean time between failures while reducing the maintenance-cost index. The study nevertheless emphasizes that algorithmic accuracy alone does not guarantee maintenance effectiveness. Data quality, false alarms, model drift, cybersecurity, organizational capability, interpretability, and human oversight remain critical determinants of successful implementation. Predictive analytics should therefore be understood as a decision-support capability that complements engineering judgment rather than replacing maintenance professionals.
