What is the problem about AGVs load/unload sequence?

Hello there,

Boxes are taken from StartPoint and moved to Stations 1 and 2. After the process, the boxes are taken by AGVs and moved to EndPoint.

However, AGVs do not empty the first station as often as station 2, and the first processor is waiting idle. My goal is to increase the number of stations to 9 and add the required number of AGV to the system.

What is the problem at station 1? Do you have any advice for the stable operation of the system when I increase the number of stations to 9 and increase the number of AGV?

Thanks for your kind support.

Hi @gokhan.k2,

I think the main reason why the AGV is not picking up processed boxes at Station1 is because it is staying in unload mode if it plans to unload its second box in unload 2. When it hits the activity "Should I Stay in Unload Mode?" it returns "Yes", then immediately travels to the next unload point.

By changing the "Conditional Decide" within that decide activity to 0, you can change the model behavior to the desired result. This will make the AGV check at each control point to see if there is work to be done:
