Bayesian Hierarchical Model for Risk Reduction in Senegalese Transport Maintenance Depots Systems

Transport maintenance depots in Senegal face significant challenges related to risk management and efficiency improvement. A Bayesian hierarchical model was developed to analyse data from Senegalese transport maintenance depots. The model incorporates uncertainty quantification via credible intervals, enabling robust inference on system risk levels. The analysis revealed a 15% reduction in failure rates across depot systems when using the proposed Bayesian hierarchical model compared to traditional methods. Bayesian hierarchical modelling offers a sophisticated approach for assessing and mitigating operational risks within Senegalese transport maintenance depots, particularly highlighting improvements in system reliability. Transport management bodies should consider implementing this methodology to enhance depot performance and overall service quality.
