How to close AGV Path

I have attached two simple FlexSim AGV model. In the first model (Path1.fsm), 2 AGVs, they are picking items from two pick up locations and dropping off in two drops off locations. The AGVs are now looping around the four short distance control points as North-West-South-East. I want to run another scenario where it should loop around four control points as North-West1-South_East1 instead of North-West-South-East. I want to close the path where West and East control points are located.

To solve this, in the second model (Path2.fsm), I have used the Way Point Logic “Look For Work” to direct the AGVs in the control points North-West1-South-East1. But, it looping around North-West1-South-East. Now AGVs are directing to the control point “West1” instead of “West” which is as expected. But, I don’t know why it is not directing to the control point East1.

Please let me know if there are alternatives ways to close the AGV network are available. Thanks.

Kind Regards,

Abdul

Because improvements and bugs are possibly fixed in later version(s) of FlexSim than the one you are running, I decided to run your model (2) in the latest FlexSim version of 17.1.2. Running your model in this version seems to work like you describe that it should work. I would suggest upgrading to the latest version. It's not worth the time to try and "fix" models in previous versions when they work in the current version. If for some reason you are unable to upgrade, you could download the Express version of FlexSim and check to see if it will also run correctly for you.

From what I see, Mississippi State U has version 17.1 of the software but may not have activated it, not sure. But they do have the latest version of FlexSim. I would ask around to see who might be able upgrade to the latest version.

I've attached your model that is now in version 17.1.2. Let us know if you have any other questions or problems.

Thank you, Jeff, for your prompt reply. I have updatedFlexSim the latest version. The FlexSim Model (path2-v1712-jn.fsm) is now looping around to the expected paths. But they are not picking items from pick up locations and not dropping off at drop off locations.

Actually, I need to build a big model which will contain a large number of paths. And, I need to close some paths (as in some paths, there might be construction works). That's why I built this simple model to test that scenario. Please let me know if there is any code I need to write or any way to close some network paths.

Thanks,

Abdul

Version: FlexSim 17.1.4

Hi,

As per your question i have attached a model below in which each model AGV's are guided in different Path based on logic preferred in Agv template.

I have used Agv Template to direct the agv to the required path and i suggested you to use Agv Template for doing routing logic when handling Agv instead of using waypoint logic.

1) In the below-attached model 2Agv's are there where first Agv will follow the path North-West1-South_East1 and second Agv will follow the path North-West-South_East.

agv-path-selection-1.fsm

2) In the below-attached model, 2Agv's will follow the path North-West1-South_East1.

agv-path-selection-2.fsm

3) In the below-attached model, 2Agv's will follow the path North-West-South_East.

agv-path-selection-3.fsm

Thank you.

Hi @gilbert jerald,

could you mind sharing what have you altered in the model besides adding the trigger On Reset on both AGVs?
