Abstract
Industrial machinery fleets in Ghana are subject to frequent breakdowns and accidents, posing significant safety risks and economic burdens. A Bayesian hierarchical model was developed and applied to data from industrial machinery fleets. The model accounts for variability across different machines, operators, and maintenance practices. The model revealed that incorporating predictive maintenance reduced the likelihood of equipment failure by approximately 30%. The Bayesian hierarchical model provided a robust framework for identifying key risk factors and optimising maintenance schedules in industrial machinery fleets. Industrial operators should consider implementing the recommended maintenance strategies to enhance fleet reliability and safety.
