A computerized simulation model has been developed to analyze the truck fleet composition at a concrete batching plant. Historical data collected at the plant is input to produce information upon which selection of the fleet may be made. The model is described including the necessary input data, the simulation process, and expected results. An important aspect of simulating different fleet compositions is the effect of customers' order quantities being influenced by the truck sizes in operation at the plant. This feature is examined and the statistical analysis outlined to determine the percentages of order switching. The results of the simulation runs produce daily quantities of concrete sold, number of trips made, percentage of empty space carried, and unit cost of concrete transported. This information together with experienced managerial judgement aids in selecting the most appropriate fleet of trucks for a particular plant.
