Multilevel regression analysis shows cost-effectiveness of machinery fleets in Tanzania, indicating management improvements are needed.

The study aims to evaluate the cost-effectiveness of industrial machinery fleets in Tanzania using multilevel regression analysis.
Utilized multilevel regression analysis to assess fleet costs and operational efficiency.
Analyzed data from 50 randomly selected industrial enterprises.
Considered both firm-level factors (size, sector) and machine-level factors (model, usage frequency).
Revealed a significant interaction effect between enterprise size and machinery type on total fleet costs.
Medium-sized enterprises incur higher costs when using more expensive machinery.
Found that regular maintenance can help minimize operational inefficiencies.

Bwire et al. (2010) studied this question.
