Queuing Theory Simulation

I had to make a simulator for an OS class I took. Basically it can be used to find the optimum number of systems one would need to place in a bank of dispatch servers and another bank of processing servers.

The simulation uses a poisson process along with random failure factors to find optimal solutions.

I'll be honest, the professor never gave us an answer for this problem, so I have no idea if it is correct. If anyone has any clue about its correctness, I'd be interested to know

The whole thing was implemented with a perl script.
