Evaluates cost-effectiveness in South African industries, suggesting optimized configurations for savings.

The study aims to assess the cost-effectiveness of process-control systems in various South African manufacturing sectors.
Utilized a mixed-methods approach combining qualitative insights with econometric analysis.
Employed panel data estimation techniques from South African manufacturing sectors.
Applied ordinary least squares (OLS) regression models for cost-effectiveness estimation.
Found a specific configuration of monitoring and control devices can reduce operational costs by up to 15%.
Significant cost reductions were particularly noted in metal fabrication processes.
Optimal use of process-control systems varies by sector but generally results in substantial cost savings.

Mkhize et al. (2012) studied this question.
