This evaluation aims to assess the cost-effectiveness of process-control systems in South Africa's industries.
Utilized a mixed-method approach combining econometric analysis and case studies
Applied panel data estimation (PDE) using generalized method of moments (GMM)
Modelled operational costs and production quality for different automation investments
Performed robustness checks using heteroskedasticity-consistent errors
Moderate investment in automation technology can reduce operational costs by up to 15%
Significant improvements in production quality were observed
Demonstrated potential for enhancing economic performance and environmental sustainability
