I want that the AGV can turn at the intersection when a deadlock occurs.

Dear FlexSim Community,

As you can see, I am trying to use this layout to perform material transportation tasks.

My idea is that if one of the AGVs causes a deadlock at an intersection, first determine which intersection it is at, and then determine which AGV it is. After determining which AGV it is, move it away first, stop for 5 seconds, and then let the AGV return to its original position.

The traffic avoidance logic at the intersection is as follows:

I want the AGV to return to where it was originally expected to go after turning, but the token generated by my newly created Event-Triggered Source (On deadlock) is different from the original token, so I don’t know how to make the AGV execute the original itinerary.

If I don't solve this problem, there will always be a deadlock situation.

Can anyone help figure out the error?

There are two path systems in FlexSim. An AGV path system behaves like a railway. A network node system acts like a road. Turning of vehicles matches better with a road system.

@Joerg Vogel

Thank you for your reply.

If I use the network node system, will the AGV move according to the from-to table I created?

Or can AGV path system and network node system be used at the same time? If so, can you give me some examples?

Thank you in advance.

You can use only one path system at a time.
An AGV System can detect failed allocation of a control point. Then you can redirect a vehicle to a different destination for example a control point or connected object to detour this vehicle.

A network node system relies on another tool to detect a deadlock. It is the agent system. Once a collision is detected you can detour your still movable vehicle to a different destination like a network node or connected object.
