Analysis evaluates operational costs in industrial sectors, suggesting maintenance improvements for cost savings.
Industrial machinery fleets in Ghana are a critical component of various sectors including manufacturing, construction, and agriculture. The study utilised a fixed effects model to analyse panel data from multiple industrial sectors in Ghana. The model is specified as: Yᵢₜ = eta₀ + eta₁Xᵢₜ + uᵢ + eᵢₜ, where Yᵢₜ represents the operational cost of machinery fleet in sector i at time t, and Xᵢₜ includes variables such as machine age, maintenance frequency, and usage patterns. Robust standard errors were applied to account for potential heteroscedasticity. The analysis revealed that a 10% increase in the frequency of machine maintenance led to an average reduction of 5% in operational costs across all sectors studied. This study provides empirical evidence on cost-effectiveness improvements through targeted interventions, offering insights for policymakers and industrial stakeholders in Ghana. Policymakers should encourage regular maintenance schedules and promote the use of energy-efficient machinery to enhance fleet performance and reduce costs.
