duniform item type creation and arrival scheduling

I made a workshop simulation where i use a global table and item list to create products each with it's own process route and processing time.

I was successful so far, but i want these products to arrive only once.
I tried arrival scheduling but i noticed that the source creates those items randomly and i can't figure out how to control exact item types.


I've attached screen shots from the simulation. Any ideas?

Up to 12 attachments (including images) can be used with a maximum of 23.8 MiB each and 47.7 MiB total.

When you use Arrival Schedule, did you make sure that the Repeat Schedule/Sequence box was left unchecked? If this box is checked, it will continue to make items on a repeated cycle. If you un-check it, the items will only be created once.

Alternatively, you could use Process Flow to create the objects at the beginning of your model run and then send the token to a sink.

@tanner.p yes the box is not checked. The problem is that the items being generated are random and i can't specify a quantity of each specific item type

@Muhammad A4,

Can you upload your model to this post? I'm not sure why it's not working. The table you have set up has one Type 1 item arriving at time 0, one Type 2 item arriving at time 1, one Type 3 item arriving at time 2, etc. Is this different than what's happening?

It worked on a later trial yesterday, not sure what was the problem exactly

It was not what is happening, the source generated random item types that i did not mention in the schedule, but it works just fine now


Thank you for helping
