Question: A building-materials firm loads trucks with two pay loader tractors. The distribution of truck-loading times has been foqnd to be exponential with a mean loading_ time of 6 minutes. The truck interarrival time is exponentially distributed with an arrival rate of 16 per hour. The waiting time of a truck and driver is estimated to cost $50 per hour. How much (if any) could the firm save (per 10 hour day) if an overhead hopper system that would fill any truck in a constant time of 2 minutes is installed?
