Hi,
I am trying to change the amount of resources in a resource pool between a day shift and a night shift (different number of forklifts).
I have created a system which sends a signal of four during the day hours and two during the night but this gets added when the message is sent to the resource pool (added all the time so I end up with well over 200 forklifts).
What is the correct way to vary resources in a pool since the input value cannot be negative (so cannot withdraw resources).

One way is to create a Gate, and not to let entities when the resource is not sufficient. The other way, which is the better but harder way, is to use MATLAB Discrete-Event System (MDES) block.
