Airport simulation issues

Hi!

I am trying to simulate the arrival of planes "one by one" to give them maintenance.

It is assumed that the frequency of arrivals is exponential with an average of 10 hours/plane, so once they land they are sent to wait in a hangar that has a maximum capacity of 400 planes. However, after waiting in the hangar, they are randomly sent to an inspection center (there are 2 of them and in each one only one plane is inspected at a time for a uniform time of 40 +-25 hours). After this, the plane is sent to another side of the airport to be cleaned, and where before there is an infinite waiting line where the planes wait to be cleaned. There, a crew of operators clean one plane at a time and the cleaning time follows a Triangular distribution with a minimum=10, a mode=15 and a maximum=20 hours.

All transfer times are considered to be negligible (close to 0)

And once the cleaning is finished, the plane leaves the airport.

The objective of this simulation is primarily to improve the overall times it takes for an aircraft to leave said airport.

I am a student and I would like to be able to pass the complete concept to the simulation in the best way to be able to do the necessary analysis and bring a solution to my class.

Any advice you can give me is welcome.

Thanks!

You can model this with simple queues and processors, although the numbers tell you what will happen even without modelling. For steady state the inspections needs to match the 10/hour but at the moment it is at 20/hr. Same for cleaning - it needs to average 10/hr but it's 15/hr.

The simulation will give you stats on queues etc. once you reach steady state, or tell you how long it takes for the hanger to fill if you leave it as it is.
