Why does my simulation abruptly stop?

[ FlexSim 17.0.1 ]

Hello, I'm new to Flexsim and everytime I try simulate my AGV the simulation stops exactly at 11.22 sec At this point the Source's state is "waiting for transport". It's a simple layout and I only want to make the AGV move along that path for now. What am I doing wrong?

@Naheed Rihan Could you please add your model. It is almost impossible for us to know what is wrong this way.

Hi @Naheed Rihan. Usually, if the simulation just stops, it is because there are no more events to be executed. Possibly your AGVs are in a deadlock situation or their tasks are not created correctly. It would help if you would be able to attach the model for us to take a look at it. If the model contains sensitive information, you can either strip it down / anonymize it to the minimal set of objects required to demonstrate the problem, or make a new Private question that only FlexSim support can see. Otherwise, feel free to attach it to this question using the Edit button.

@steven.hamoen @Mischa Spelt This is my model, I understand it's very basic but for now I'd simply like the AGV to travel along the path. The extra control points I've added are to indicate future stations that the AGV would have to visit as I develop my model. Please tell me what's wrong with my model and how I can make it better 🙂 Appreciate the helpn-test-2.fsm

Also, since I'm new I would need some guidance as my AGV layout and model develops. Any suggestions on online resources? or someone who I can correspond with via email/skype?

Hi Naheed,

Thanks for adding the demo model. It looks like you have connected your AGV to the Dispatcher the wrong way 'round. Note that even though the Source connects to the Dispatcher through a center port connection, the Task Executers are connected to the Dispatcher by regular ("A") connection and such connections have a direction. They should point from the Dispatcher to the Task Executers.

If you disconnect ("Q") the AGV from the Dispatcher and then connect ("A") the Dispatcher to the AGV the model runs.

@Mischa Spelt Thank you Sir! that worked
