One more problem with Coovid-19 Model.

This is a slightly revised model that @jason.lightfoot helped me with last week and @Matthew Gillespie a week before that. That model can be see here.

I modified the sequence of Activities from "Release Seat" to "Walk to ExitSpot" in order to reduce the time from Marking a Seat as Used to pulling the records from the list. It seemed to me that this delay was preventing an accurate count of the seats in use.

The model seems to be working much better now but at approximately 9:40 6 AM, 11:45 AM and 2:40 p.m. a patient arrives and no seat is immediately available. An entire the row of seats becomes available shortly after that patient arrived but the patient does not "see" the seats until another entire row of seats become available becomes available. This is sufficient time for 10 or so patients to join the waiting line. Then all the waiting patients go to those 2 rows of seats. I do not know how to correct this.

Thanks

After clearing the InUse label on the chairs in a row, you can call the reevaluateBackorders() method on the Locations list to let anyone currently waiting for a chair know that there's a new chair available.

List("Locations").reevaluateBackOrders();
