Generate different order sequence and get the WIP result

Hi all,

I have a problem with seeking an optimal sequence of orders.

For example, I have a line with 3 type of products (1,2,3) coming with its batch size. Then when I run the model with difference sequence (1-2-3 or 3-2-1 or 2-1-3...), the WIP at input queue (in P2, in P3, in P4) will be different accordingly. Any possibility that I can set up FlexSim to generate the sequence automatically and get the WIP result? Then I can decide which sequence provide me the minimum WIP. If yes, please help to guide me. Thank you.

I put the file here for you to take a look: trial_1.fsm

Software Version:

FlexSim 23.0.8

You can use a Sequence type parameter. A Range Based experimenter job will iterate through all possible permutations of the sequence.

Tying the sequence to the creation of items is much easier through Process Flow. Each token can be assigned a row from a table that stores the batch sizes of the different types.
