Production problem

hello, I'm a student and need to work with flexsim for my internship.
The problem is that I don't know how to run the next data in flexsim.

I have made the model, the thing I want to know is:
I need to produce batches every time a different batch. The batch sizes for the batches has to be picked bij chances:
0 - 100 25,84%
100 - 200 23,15%
200 - 300 15,44% so on

After the batch size is picked the hole batch need to get the same item type,
1 - 19,3 %
2 - 15,6 %
3 - 17,5 %
4 - 7,5 %

when this is done the products go to the first processor after they come out of the processor the are combined on a pallet 50 quant per pallet.
The next thing I need to know, after the first proces the item types have to change but not every single one but the hole batch size. the itemtype it gets needs also to be taken from te following data:
1 - 23,9%
2 - 18,2%
3 - 11%
4 - 25,7%
5 - 13,8%

could someone help me with this, Thanks

Guus,

take a look at the "dempirical" in the command list. That is the distribution you need.

For the first itemtype, take a sample using the demperical distribution, put it in a label on the source and use the label to set the itemtype. And every time you reach the end of the batch (being a multiple of 100, look at the functions "fmod" and "getoutput") you take a new sample and put that in that label again.

Use this same structure for after the process.
