The wheat harvesting season in the American Midwest is$$ short, and farmers deliver their truckloads of wheat to a giant central storage bin within a $-$week span. Because of$$ this, wheat$-$filled trucks waiting to unload and return to the fields have been known to back up for a block at the receiving bin. The central bin is owned$$ cooperatively, and it is to every$$ farmer's benefit to make the$$ unloading$/$storage process as efficient as possible. The cost of grain deterioration caused by unloading delays and the cost of truck rental and idle driver time are significant concerns to the cooperative members. Although farmers have difficulty quantifying crop$$ damage, it is easy to assign a waiting and unloading cost for truck and driver of $$$ per hour. During the $-$week harvest$$ season, the storage bin is open and operated hours per$$ day, $7$ days per$$ week, and can unload trucks per hour according to a negative exponential distribution. Full trucks arrive all day long$($during the hours the bin is$$ open$)$ at a rate of about per$$ hour, following a Poisson pattern.
