Packing items on pallet

Hi everyone,

I am currently stuck in this modelling problem trying to pack items on pallet. First i have two sources: one for the pallets and the other one for panels producing different randomized products according to their lenght. I would like to pack my item with same lenght on the same pallet and the one with different lenght in separated pallets. Also i have boundaries on quantity that can be packed on a pallet:

- Where Lenght < 151 i can pack a maximum of 168 items on the pallet

- Where Lenght >= 151 i can pack a maximum of 84 items on the pallet I

I personally created a process flow model but it happen that the token get stucked in the process at some point. How can i overcome that ? Do you have any other solutions to model this problem ?

Thank you

The token can't continue because activity Pull A from List is failing, as there isn't any item whose length is less than 151. If you want to prorize A, try to use max wait timer = 0 and destination = 2 option to continue if the pull fails.

Hi thank you for the response. How can pull quantityA or quantityB based on the label Lenght that i assigned to the token of the list. Does the label in the list refer to the label assigned to the item on creation ?

Do you have any other suggestion for modelling the problem above ?

Check this logic, i think its working like you want.

Now the logic that pull items its a loop that stops when there isn't more pallets or items to pull.

I hope it helped you.

Hi Lago thank you for the precious suggestions. I just tried the model on mine. It keeps get stuck and i do not know why. Just another question do you know if there is a solution to pack items with same lenght in the same pallet? Avoiding the fact that items with different dimensions have been stacked in the same pallet.

Thank you in advance
