Manufacturing systems in Ugandan plants are crucial for food production, but their reliability varies significantly. Panel data was collected from Ugandan plants over two years. A mixed-effects logistic regression model was employed to analyse the data, accounting for both fixed effects (plant-specific characteristics) and random effects (time-invariant factors). The analysis revealed that plant age had a significant impact on system reliability, with older plants showing lower reliability. Panel-data estimation successfully identified key drivers of manufacturing system reliability in Ugandan contexts. Investment strategies should focus on upgrading older plants to improve overall system performance and reduce reliability issues.
