Processflow method for truck traffic analysis

Hello,

I am trying to build a model of trucks coming into a facility, unloading at the warehouse and leaving. I am using conveyors, truck objects, and custom flexsim logic to achieve this. It works as intended, but am wondering if it is possible to build something similar in Processflow. I did try going through the tutorial to figure this out, but am not able to find a way to start. I am hoping someone has tried something similar, and can help me get started. I am attaching a sample model of the scenario I described.

In the attached model, trucks can go right or straight based on the itemtype, read at the decision point.

Thank you!!

which aspects of the process would you like to be controlled by process flow? I would also suggest using the AGV paths for the movement of trucks rather than conveyors. The AGV paths aren't specifically for AGVs, but for any task executor.

Hi Joshua

The frequency of trucks coming into the warehouse varies, and also the final destination of the truck. I am able to easily create these frequencies and assign destinations using a combination of source and labels, which is the reason for using truck objects. The destination of the trucks can also change, if the docks are all occupied, which will only be known at the entry gate. I am currently able to divert the truck to a waiting area(Queue) using a decision point on the conveyor. Can these activities be done using AGV paths and task executors, if yes, can you please provide an example on how to achieve this.

Thank you,

Achuta

@achuta.kalidindi

Sorry I never got back to you about your question, is your process still the same or did you make changes to it? Either way I can help you if you are still need any.

Hi,

As per your constraint, I have Built a sample model in which truck will be created and do check-in process at the security gate and travel to dock door to unload the items in the dock door. After unloading the truck will move to check out gate and undergo a security check process and finaly the truck will get destroyed.

I have attached the sample model for your reference have a look at it

support-truck-movement.fsm

Note: To accomplish this logic I have used AGV network path and control points to make the truck to travel in the model and use the General Process flow to control the required logic in the model.

I strongly recommended you to have a look at AGV Process flow template that tells you in details how to make the logic to control the trucks in the model. there is more forum model available have a look at it because the model that i attached is just a hint to start your big model so have a look in AGV process flow template since this will be very much useful for to future model built up.

Thanks

Hi,

Is this model helps to built your truck model

Thanks

Thank you Gilbert, this is what I was looking to do, I am going through the logic and the AGV process flow template to try and understand how the custom code is working. Thanks again, this is very helpful!!

Here is another simple demo model using process flow and AGVs.
