The Tactical Vehicle Fleet Simulation TVFS Model is a computerized stochastic representation of vehicle fleet operations. The model accepts descriptions of vehicles comprising a fleet as to capabilities and operational characteristics. Then, based on the generation of mission demands, it dispatches, loads, transits, unloads, returns, and maintains the vehicles over time. The model reports the overall utilization of the fleet and measures vehicle performance in terms of dispatch delays and in terms of the times required to complete requested missions. On a more generalized basis, the TVFS model can be described as a discrete event queueing and service model. It generates events, such as missions and maintenance actions, according to prescribed statistical distributions. It then keeps account of the time required to service each of these events with respect both to the type of event and to the type of server i.e., vehicle. Results are displayed in terms of explicit frequency distributions of the delay and service times, as well as comprehensive summary statistics.
