Implementing Conditional Path Access Based on AGV Load State and Station Occupancy

[hbg485]

Hello, I would like to ask for guidance regarding a routing constraint in my current AGV model.

In this scenario, adding new paths is not an option, so I need to handle route permissions using the existing paths only.

The intended logic is as follows:

• If the AGV is empty, it should always be allowed to pass under the station, regardless of whether an item is present on the station.

• If the AGV is loaded and the station has an item, the AGV should not be allowed to use the under-station path and must instead take the lower bypass path.

• If the AGV is loaded but the station has no item, the AGV should still be permitted to pass under the station.

I would like to confirm whether such conditional path access can be implemented strictly using the existing path network, without adding new paths.
If so, I would greatly appreciate any recommendations on how to structure this logic, or which triggers/delegates would be most appropriate.

Thank you in advance for your support.

You can add a control point for each storage location and dynamically change its routing constraint when a vehicle starts a travel task. Check out the KIVA demo model for an example. https://forums.autodesk.com/t5/flexsim-knowledge-base/kiva-system-demo-model/ta-p/13520232

I attempted to implement this based on the post you shared.
However, managing deadlock avoidance under different scenarios has proven to be difficult given my current level of experience.
I would sincerely appreciate any advice or suggestions you may have.
