Methodological Evaluation of Process-Control Systems in Ghana: Multilevel Regression Analysis for System Reliability Measurement

Abstract
Process-control systems are crucial in engineering for ensuring quality and safety across various industries in Ghana. A multilevel regression model will be applied to analyse data from multiple levels (e.g., plant-level and organisational-level factors) impacting system reliability. The multilevel model reveals that both plant-level investments ($\beta<em>1$ + $\beta</em>2$) and organisational support ($\beta<em>3 + \beta</em>4$) significantly contribute to system reliability, with coefficients indicating positive effects (e.g., $\beta<em>1 = 0.67$, $\beta</em>3 = -0.35$). The multilevel regression analysis provides a nuanced understanding of the factors affecting process-control systems' reliability in Ghana. Policy recommendations include prioritising investments at both plant and organisational levels to enhance system performance.
