AGV Routing

Morning All,

I have this model that i am trying to use task executor-AGV to do warehouse picking, currently the AGV will only pick one order at a time while the other AGV stays idle, there are also times where a AGV executor will block other AGV within the network from dropping off the items at the processors. Is there any way i can magv setup.fsmake them concurrently pick up the boxes from the racking and drop them off at the processors.

Thank you!

You currently create a single task sequence for the entire order. You should instead create a task sequence for each item. Also run the subflow tokens in parallel.

Additionally, placing more control points will allow the vehicles to follow each other more closely.

Hi Felix,

Thank you for your help, currently i face another issue where the flow get stuck because the AGV gets assigned to 3 tokens, is there any way to make it so that it takes 1 token at a time?

Thank you!

As far as I can tell all critical issues in your model are caused by not waiting until pallets have finished processing before transporting them further. A simple method for syncing the 3d model and Process Flow would be to have the processor push the pallet onto list in the Send to Port field or the On Process Finish trigger. The token then needs to first pull its pallet from that list before it can start the next transport process.

You should also strive to get rid of the other error messages:
At the initial label assignment you are using the Type value as row number, but the Type values are outside the range of the table -> instead first store the row number on a label, then read Type and SKU based on it).

Sometimes negative delay times are generated by the normal distribution you are using there. You can use "Math.max()" to use 0 when a negative value is generated or you write a while-loop in the code that generates new values until its positive.
