Let AGV automatically choose other available path

I have a question about AGV routing. In this simple model I attached you can see that taskexuter4 has 2 possible routes to go to ControlPoint12. If I click on show routing accessibility for CP12, it also shows that this is a possible route.

If I let an AGV travel to the middle CP on the straight path first, obviously that CP is allocated and then I would expect the other AGV to choose the second possible route, however he doesn't and he keeps waiting until the middle CP gets deallocated. How is it that the AGV doesn't recognize the 2 possible routes?

@bert.s10,

You might consider the use of Way Points for the AGVs. There's not any inherent logic in the AGVs to look for alternative routes if the route they intend to take is occupied. But, if you add Way Point logic, I think you can make this work. Hopefully someone else can chime in who knows more about Way Points, but I can at least get you started.

The Way Point logic I used redirects the AGVs by searching through all of the "NextLookForWork" points attached to the Way Point member CP. You can adjust this logic and add park points, alternative paths, etc. Unfortunately, I'm not an expert in this area, but I hope this at least helps spark some ideas.

Hi @ bert.s10

I have used Next look For Work logic to choose the available Path to move the AGV. I have attached a model for your reference have a look at it Support two-possible-routes.fsm
