This section discusses a more complicated model to demonstrate some of the additional features and capabilities of Simulation Studio, including compound blocks, branching based on probability, and using the various plotting blocks to monitor the status of the model as it is running.
Suppose parts arrive at a repair shop at a rate of four per hour. Upon arrival, a part is taken to the service desk where
it is inspected. The time it takes a person to inspect the part is uniformly distributed between 5 and 15 minutes. The service
desk can repair of the parts. The rest require more complicated repairs and must be sent to the repair station. At the repair station, the
part is worked on by a repairman. The time it takes a repairman to diagnose and fix the problem is uniformly distributed with
a minimum of 10 minutes and a maximum of 45 minutes. With a probability of 0.09, a repairman cannot fix the part, and it is
sent to the scrap area. Otherwise, the repaired part is sent on to a quality control manager who inspects the part to determine
whether it has been repaired properly. The quality control manager sends
of the repaired parts back to the repair center for further repairs. The rest of the parts that pass inspection are sent
on to the part pickup area. The time it takes a quality control manager to inspect a part is uniformly distributed between
6 and 18 minutes. Two people work at the service desk, and two people work at the repair desk. Assume the travel time for
parts between all stations is 1 minute. The shop is open from 9:00 a.m. to 6:00 p.m., Monday through Friday. The simulation
is run for one work week (45 hours).
