Table 4 Maintenance strategy for different decision-making priorities.
Decision priority | Recommended strategy | Justification |
|---|---|---|
Minimizing long-term costs | RL-M | Achieves the lowest C∞ (7.4) due to AI-driven optimization |
Balancing cost and robustness | PHM-CBM | Maintains low cost variability while reducing failures |
Reducing downtime probability | RL-M, PHM-CBM | RL-M prevents unexpected failures, while PHM-CBM reduces hazard-based risks |
Minimizing cost variability | Hybrid PPM | Balances predictive scheduling with preventive actions |
Simple, low-cost implementation | QIR | Requires minimal computational resources but remains more cost-effective than BR |
