Flow time optimization

Hi,
I want to create an optimization model to minimize total flow time by changing priority of Orders on each machine. Each machine has a fixed setup time and has a process time for each order calculated by "Process time" table" by a custom code. Each order can be done by one or more machines.
My question is :
I want each machine to pull the Order with minimum priority label & the order with diameter within range of machine range, from "machine dimensions" and "process time" tables.

Thank you in advance

You can put the diameter constraint on the pull requirement which will work in parallel with the pull strategy.

You can either add those to a schedule arrivals table or sequence, or generate an order number from 1-5 and use the row to look up the values and add the labels on creation at the source.

Thanks for your help, i don't know about the second option but for the first i want to get labels from the table so i can increase or "orders" directly from the table

Second i need to link the parameters sequence as a priority for the order
