Industrial machinery fleets play a critical role in Rwanda's manufacturing sector, but their operational efficiency varies widely. This study employs multilevel regression analysis to assess the impact of fleet management practices on maintenance costs and productivity across different sectors. The model incorporates fixed effects for geographical regions, which account for local economic conditions that influence fleet performance. There is a significant positive relationship between proper fleet management practices (such as regular maintenance schedules) and reduced maintenance costs by around 15%, with no adverse impact on productivity. The multilevel regression analysis has provided insights into the cost-effectiveness of industrial machinery fleets in Rwanda, highlighting the importance of standardised maintenance protocols across different sectors. Implementing a unified maintenance schedule and regular audits could lead to substantial savings without compromising operational efficiency.
