Process Flow

Hello, Flexsim community, I've been assisted by the community, and I have a Flexsim model, version 2019, which I've attached. I'm facing an issue where I want Transporter2 to move 150 boxes from Queues 3, 4, 5, and 6 to QC, and after QC completes its process, Transporter2 should transport items from Queue7 to Sink1. After that, both Transporter2 and Transporter3 should collaboratively move the remaining items in Queues 3, 4, 5, and 6 (5850 boxes) to Sink1. I mean after passing through the processors, Transporter2 will bring a small sample (150 boxes) for QC inspection, and the remaining items will be directly sent to Sink1 without going through QC again. I seek your assistance and have attached the Flexsim version 2019 file. I appreciate and hope for your help.

That should be relatively straightforward to build in an Object/Instanced Process Flow where Queues 3-6 are the instance objects. An Event-Triggered Source reacts to the entry of items. The resulting tokens are batched (Batch activity) until there are 6000 and the item references assigned in the source are made into an array.

Acquire the QC and a forklift and move the first 150 items to the QC, wait for its process to finish and move them further to the sink. Then transport the rest of the items to the sink (nested subflows; 39 tokens that move 150 items each).

I appreciate it, Felix. You always help me. I'm very grateful because I'm just learning how to use the process flow. So, could you please take a look at the layout I've used as shown below? Does it match your description?

Looks good so far! I guess it ends at the point where the token is currently waiting for the QC to finish. But the rest will pretty much consist of the same types of blocks.

I have done it and encountered an error. I have read the instructions about Batch, but I really don't understand what Batch can do in this case. Can you help me, please?Process Flow.fsm
