Abstract
Depot maintenance systems play a crucial role in ensuring the reliability of transport infrastructure in Senegal's mining sector. A quasi-experimental study was conducted using data from 10 depots over two years. The study employed statistical models to measure MTBF with robust standard errors. The analysis revealed a mean MTBF of 365 days across all depots, indicating consistent system performance under the studied conditions. Depot maintenance systems in Senegal need further optimization for reliability improvements. The study provides a framework for future interventions based on empirical evidence. Implementing preventive maintenance strategies and regular equipment upgrades can enhance depot reliability.
