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

Hi! Check the functionalities of the batch activity, it can help you matching tokens by labels (or the items as token.item). Then, when you complete a stack (the quantity you want) of tokens that represents items with same length, make the move object of those items to an empty pallet.
