The cost-effectiveness of process-control systems in South Africa's manufacturing sector is a critical topic for improving productivity and sustainability. Panel data analysis was employed to assess the performance metrics associated with different process-control systems over time in South African manufacturing firms. The model used is represented by y₈ₓ = eta₀ + eta₁X₈ₓ + uᵢ + vₜ, where y₈ₓ represents the cost-effectiveness metric for firm i at time t, and X includes control variables such as firm size, industry type, and process complexity. A significant positive relationship was found between the adoption of advanced control systems (ACS) and improved energy efficiency, with an estimated coefficient of 0. 85 on ACS adoption in the model. The empirical results suggest that certain process-control system configurations can lead to substantial cost savings and improvements in operational performance. Firms should consider adopting ACS based on their specific needs for enhanced energy efficiency, thereby potentially reducing costs and improving sustainability.
