This simulation is a process model representation of multiple call centers. Calls are generated then processed by a center. Each center has a certain amount of staff available to answer calls.
There are two possible orientations to this model. If
queues is set to "multiple", then each call center can only answer the calls that come into it.
queues is set to "single", then as calls come in, they can be assigned to any of the centers. They are assigned based on the availability of staff in each center.
By running the Optimize Configurations experiment, the engine will compare the effectiveness of each configuration and highlight the one which reduces the average wait time for calls. By clicking on the "All Runs" option in the Activity Sidebar, you'll be shown the comparison between the two configurations' performance in the Analysis tab.
