A comprehensive evaluation assesses cost-effectiveness in manufacturing plants, indicating areas for operational improvement.
Manufacturing plants in Ghana face challenges related to operational efficiency and cost-effectiveness. A comprehensive study employing multilevel regression analysis was conducted. Data from 50 randomly selected plants across the country were analysed to assess system performance and costs. The analysis revealed that plant size has a significant influence on operational efficiency, with larger plants showing higher cost-effectiveness ratios (CERs). This study provides insights into optimising manufacturing systems in Ghana by identifying key factors for improvement. Implementing process improvements and training programmes tailored to specific plant sizes could enhance overall performance and reduce costs.
