How to run two sub flows assigned to two diff.tasks parllely using Process Flow

Hello Everyone,

Recently I started working with Flexsim and did a lot of interesting tasks, cases etc. A few days ago when I planned to establish a case (below mentioned) in Flexsim I addressed a lot of problems. I tried my best and posted this here so that can share and gain some knowledge.

My primary goal is to load flow items from multiple Queues and distribute them to delivery queues using AGVs. For a better understanding, refer to the attached image.

Process 1: AGV 1 should load a Flow item from Pickup queue1 and deliver it to Delivery Queue 1.

Process 2: AGV 2 should load a Flow item from Pickup queue 2 and deliver it to Delivery Queue 2.

I created a process flow and added two subprocess flows to it (Process 1 and Process 2 ) to execute the above tasks.

Is it possible to run two different sub flows parllely?

Here is the file on which I worked Running_Two_Subflows_Parllely.fsm

Software Version:

FlexSim 22.2.2

Instanced process flow is made for this kind of logic. You build only one task sequence. An instance is applied to each of your Taskexecuter.

Respected @Joerg Vogel Thank you for the Response. Could this case be possible in the same process flow?

There are many ways to do this.

If you're trying to coordinate a single token on completion of both subflows , you could use split and join activities to create two tokens, each of which would invoke different subflows

Or you could define a single subflow that refers to token labels rather than directly referencing objects in the model, and then set the number of tokens to 2 on the runSubflow, adding the required labels to the created tokens based their creationRank.

Respected @Jason Lightfoot I solved the preceding problem using process flow instances, and it worked. However, for each instance, I must create a new task executer group and source. Is there a way to attach all task executors to a single group and just to one source for acquisition?

Can you share your model?

Thank you @Jeanette F for responding. Here is the model running-2-subflows-parllely_using_ProcessFlowInstances.fsm

I did my best with the flexsim knowledge I have. Please correct me if I did any mistake.
