Hello all.
I'm stuck on a project I'm working on. I'm trying to simulate a supermarket, where the cashiers open new check-outs when necessary (2 are always open and when there are 5 or more in queue they open another). To simulate this I've using 4 servers, with paths leading from the source to the first two nodes, setting up a balking system and then pathing from the first two servers the third server, and then the same for the fourth server, but the supermarket also closes the check-outs when there aren't enough customers to need it and I've been unable to figure out a way to do this.
