Think of a large factory that moves jobs from one workstation to another using fork trucks. When a workstation has filled up a bin that is ready for a fork truck, it sends out a signal to a central dispatching area. When the signal comes in, the dispatcher will assign it to the next available fork truck. On average, the dispatcher gets about 29 signals per hour. There tends to be a lot of variability in these signals and the SCV has been estimated at 2. It takes a fork truck 6 minutes, on average, to get to the job and move it to it destination. The SCV of the move time is estimated at 1. There are currently 4 fork trucks on duty. What is the current utilization of the fork trucks and the current average time that a job spends waiting to be assigned a fork truck? What would happen to the time a job spends waiting if the number of fork trucks was reduced to 3?
