Grain Flow Restrictions in Harvesting-Delivery-Drying Systems

ABSTRACT A model has been developed which simulates the har-vesting, delivery, and handling of grain for any specified grain production enterprise. This study describes the procedures used in validating the model. A time and motion analysis was used with three sets of ac-tual field observations. A comparison is made between simulated and measured values for total grain harvested, number of combine and field unloadings, and vehicle wait time.
