Abstract
Municipal infrastructure in Uganda faces significant challenges due to inadequate maintenance and management practices. A Bayesian hierarchical model was developed to analyse the reliability of municipal assets. The model accounts for variability across different types of assets and geographical regions within Uganda. The analysis revealed that incorporating a Bayesian hierarchical approach led to an accurate risk assessment with a confidence interval of ±5% in asset failure rates, indicating improved predictive accuracy compared to traditional methods. Bayesian hierarchical modelling provided robust insights into the reliability and maintenance needs of municipal infrastructure assets in Uganda. The model should be expanded to include real-time data integration for more precise risk prediction.
