How to change state of patient when performing animation?

I am busy with building a simulation model of a hospital. When I added a state pie for the patients I noticed that if a patient is performing an animation, for example taking place on a seat in the waiting room, this counts as idle time.

Can I change the state of a patient during an animation somewhere?

Are you talking about the second it takes the person to sit down? If so you're not using realistic process times. Most process times and travel times are much longer than the brief moment it takes a person to sit down, so that time should not even really show up in the course of a patient's flow.

Yes, I put in just one patient in the model to see what happens. Then, if you add up the time of all the animations of a patient throughout the hospital I end up with 0.39% idle time on a total time of 4.15 hours that this patient spent in the hospital.

You can customize the Enter and Exit instructions of Location objects. You could add an enter instruction that sets the patients state using code like this:

loc.stats.state("HC States").as(TrackedVariable).value = "InTransit";

Hi Matthew,

Thanks for the answer. What is the reasoning behind setting the state to Idle instead of keeping it on In Transit for example?

The state is set to InTransit when someone does a travel task, but then reverts back to idle because the travel task is over. Then the state isn't set again until the Process activity starts.
