How to delay item creation from the start of the model ?

I want to generate a batch (1) of items every 56h that will go to half of my processors and another batch (2) of items that will go to the other half of my processors, every 56h too but i want the (2)batch to be generated 9h after the (1)batch. The processors only take 43h to deal with the item but I can't have them running certain phases at the same time so I need to delay item creation by 9h.

I've tried to do it with process flow, I don't know if that's the right thing to do but I can't link the scheduled generation of items of the process flow source to the model source. (I'm just starting on Flexsim and I'm not very familiar with process flow, i could need a little help there)

Also if there is another way to delay the processing by 9h directly on the processor or to delay the creation of items, i'm open to all solutions !

Thanks in advance !

When you use Process Flow you would create the items there using a Create Objects activity. You can set where they appear in the activity. A 3d source would not be needed.

You can set this up quite easily in a 3d source though by using the Arrival Schedule mode and setting it to repeat. The table will start from the top once the last row of items has been created. So by setting the last row to happen at the 56h mark but not actually create any items, you will get a batch every 56h with another 9h after that, as defined in the second row.
