Is there anyway to make the agv take the alternate route without using ProcessFlow in such layout below? I tried the method in this post (https://answers.flexsim.com/questions/89223/let-agv-automatically-choose-other-available-path.html), but doesn't seem to work. I know we can do it with ProcessFlow, but wanted to ask if there is anyway without using it.

The method in that post uses AGV Way Points. Your attached model doesn't have any way points. It doesn't have anything that even resembles you trying to redirect the AGV down that path.
Use the AGV.redirect() method to redirect the AGV to a control point on that path. Whether you use Process Flow, AGV Way Points, or some other custom code doesn't matter. Just redirect the AGV down that path if you want the AGV to be redirected down that path.
Unless you add logic to the contrary, the AGVs will just take the shortest path to their destination.
@Phil BoBo Thank you for your reply. I'm attaching the layout file with waypoints defined. I'm puzzled with the behavior.
1. TE1 takes the longer route instead of going to Queue2 (Shorter route and Flowitem destination)
2. The very first time TE2 travels to CP7, after arrival, it jumps back CP6.
What could be the cause?
1. The problem is the Control Point 7 is closer to Control Point 6 than control point 2 - it's only looking at the distance to the next control point, not distance to there, and then on to the final destination.
If you move Control Point 7 around the arc it works, as this is then the search result:
New CP7 location.
You could also try to add a condition so that you don't always use that search, only when you need to.
Another solution is to make the distance the total distance as per this changed ORDER BY clause:
@jason.lightfoot I tried your solution, but facing a little problem. When TE2 takes the shorter route, when it arrives at CP2, it jumps backward out of the path. It happens around 500 - 535 sec. What could be the cause? It also happened in 2020 Update2.
