How to make to wait an AGV while an other AGV is in the same path ?

Hi!

I have two AGVs and they have a missions where they must the same path ,so I would like when one GAV is in the path , the orther AGV wait and he goes after.

I have put a control area but I received a error message.

Thank you for your help.

I join you my model : it's the AGV 2&3 and the path 38 and 39.100agv123-toutespieces-tpsdecycle142.fsm

Software Version:

FlexSim 16.2.0

When I start my model , after the AGVs 2&3 are in collision in the path 38 & 39 (control point 84&85) , I put a control area but nothing change.

I don't know the logic of your model, so I don't know if I've achieved exactly what you're looking for. But the problem with your control area, is that you had created a point where there was a circular deadlock happening.

So I removed the Control Area around the junction, and instead just spread Control Area 1 out to cover the CPs on that branch of the track. It seems to have fixed your deadlock problem, and also the AGVs don't seem to be traveling down the same branch of paths as each other.

control-area.fsm

(In the example I deleted your CAD file, just because it was slowing the model run time down a lot. You'll want to make the changes in your own model with the CAD file.)

@Sam Stubbs; @Rodrigo Lamas

Now, there isn't colission between the AGV 2&3 but the AGV 2&3 didn't make their complete missions:

-the AGV 3 makes only the path between the conveyor 5 and 6. It didn't make the mission to put the pink pallets on the separators.

- the AGV 2 makes only the path between the pallets of gearbox and the separator. It didn't make the mission to put the pallet where takes place on the path 39 & 61.

Thank you for your help.

Try this one:

controlarea.fsm

Essentially just play around with the control areas. Make sure they are allowing your AGVs to get where they need to, but are also placed to restrict them from going where you don't want them to.
