AGVs unloading at a slower rate after simulating for a few hours

Hi @Felix Möhlmann ,

I have noticed that at around 10pm (57600s), the AGVs took a longer time to unload at the Linen queue, causing a long queue of AGVs waiting to unload. Not sure what could be the issue, would appreciate your advice on this. Thank you very much!

After an AGV completes a task it waits at its current position for up to five minutes for another job to become available before travelling to a parking point.

This is what is delaying the other AGVs. Since there are no pending tasks, the unload points are blocked for an extra five minutes.

Hi @Felix Möhlmann ,

So sorry but I actually don't know what the "5*60" meant. Do you mind explaining? Thank you!
So in this case, unticking the "Use Max Wait Timer" would work right?

Thank you very much!

It's the time in seconds the token will wait for something to pull. Unticking "Use Max Wait Timer" would mean the token will wait indefinitely (or at least until new jobs are generated). What you want to do is reduce the max. waiting time.

Is there a difference between "5*60" and "300"?

Thank you @Felix Möhlmann , I reduced it to just 60s
