Freight Car Unloading Dock $-$ a Simulation Exercise

There is a warehouse that has one dock used to unload

railroad freight cars. Incoming freight cars are delivered to

the warehouse during the night. It takes exactly half a day

to unload a car.

If more than two cars are waiting to be unloaded on a

given day, the unloading of some of the cars is postponed

until the following day.

Past experience has indicated that the number of cars

arriving during the night have the frequencies below:

Simulate this queuing process for a period of $20$ days and

note the results under the following columns in a report.
