ABSTRACT
In many agricultural systems, waiting lines occur, and they can be a problem. Trucks waiting to unload fresh fruit or vegetables at a processing plant, grain trucks unloading at an elevator, and customers waiting in line for service of some sort are examples. The costs of waiting lines may be a definite, measurable item, such as payment for trucks and drivers while they are being nonproductive in a waiting line, or they may be more difficult to measure, such as when customers decide to go to another place of business because lines are too long.
