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 (₁ + ₂) and organisational support (₃ + ₄) significantly contribute to system reliability, with coefficients indicating positive effects (e. g. , ₁ = 0. 67, 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.
