The aggregation period of the state gantt when the warm-up time is set

When warm-up time and state gantt are combined, the state gantt aggregates statistics for a period of at least twice the set warm-up time.

This is not a problem if the simulation is run for more than twice the duration of the warm-up time, but it will affect the simulation results if it is not.


In the attached model, the warm-up time is one hour from 8:00 to 9:00, and one item is transferred to the queue at 9:00.

Normally, the simulation should stop after the transfer is complete, but for some reason it continues to run until 10:00. Even when the warm-up time is changed,

The simulation continues to run until twice the set time.


Checking the event list, event was added at 3600 seconds elapsed, what does it represent?event-list.png

Is this event the reason why simulations run up to twice the warm-up time?

This occurs only when the warm-up time is combined with the Gantt chart.

Thank you in advance for your cooperation.

@Jordan Johnson Additional information for the developer who eventually looks at this:

The "blank" event is created for any Statistics Collector that has anything but "Do Nothing" set in the On Warmup option. It is not specific to the state gantt.

I've done some initial investigation, and it seems unusual to me. Most likely, this is a bug. I have added it to the dev list for further investigation.
