Control Point Connection Navigator Optimization

Hi,

During the simulation using the control point connection, I inquire because the path of AGV is not satisfactory.

For example, the motion moving to load items from processors 24, 26, 27, 23 shows unnecessary detours to processor 9, 13, and 19 locations.

I don't want to look like this detour.

There are shortcuts in the area where the rest of the processors are located, except for processors 9,13,19, and I want to try using these shortcuts.

The control method used advanced AGV process flow and control point connection.

I'd really appreciate it if you could help me. Thank you

With the AGV Process Flow templates the "NextWorkPoint" connections define the path along which the AGVs will travel looking for work. By default, an AGV can only 'see' a task when it passes the control point that is connected to the object the item is currently situated in. As such, up to the point when it reaches a control point where a task is available it will blindly follow the NextWorkPoint loop. If there are two or more such outgoing connections from a control point, the AGV will use them in a Round Robin fashion.

You can use work forwarding to make the AGV be able to 'see' work from farther away and avoid having to visit outlying locations just to see whether there is work available there or not.

Felix Möhlmann Thank you for your reply.

Can you refer to the model I put up and show me how to use Work Forwarding at least a part of it?

Can the AGV with Work Forwarding process flow be used with the advanced AGV process flow?

I removed some other connections for better clarity:

CP11 (red circle) only has one outgoing "NextWorkPoint" connection which leads the AGV along the shortcut. Any work of the upper six processors is forwarded to it. So if there is work available and the AGV has capacity it will take the longer route around the top to pickup the item(s). If not, it will always travel along the shortcut.

Note that while there is no "NextWorkPoint" connection leading to the upper processors, there are still connections leading back to the main loop, so the AGV can know where to travel next after it has unloaded an item to one of the processors.

I want to research while looking at the model, can I get a model?
