Simulation modelling for a bus maintenance facility

The Greyhound Lines Dallas maintenance facility was congested during peak operating periods. A stochastic model of this facility was developed to determine the resource requirements needed to provide adequate service during periods of peak demand. The structure of the simulation model is described. A representative sensitivity analysis is presented to discuss how this model was used to support facility sizing decisions. Based on our simulation experiments, we concluded that the existing site, with appropriate modifications, could accommodate peak traffic with some room for growth.
