Order picking sorted by rack label

170225- MODELE CIBLE V3.fsmWe have an order preparation model in a warehouse, and we need to optimize the sequencing of item picking to follow the picking path. This path is based on the "Zone" label (assigned to racks), ordered from the smallest to the largest.

The order preparation process (both containers "Processus reappro magasin" and "processus prepa entrepot") consists of two steps:

• Step 1: Reserving the entire stock required for the order by updating the "nb_cartons" quantity in the stock pallets. This data is stored in an array called "missions", which contains all pallets and the corresponding quantities to pick.

• Step 2: Actual picking performed by resources by updating the "NbCartonsReels" quantity in the stock pallets. They follow the missions in order, moving through the racks as they become available, ensuring that only one resource is assigned per rack at a time.
  

To optimize the picking process, we need to:

• Add the picking zones to the "missions" array.
• Sort the "missions" array by picking zone, so, for exemple, that the resource picks first from rack "zone = 1", then "zone = 2", and so on.
  

I’ve attached the model.

Do you know how I can modify my model to incorporate this complexity?

Thanks in advance!

One way is to push all missions onto a list and then pull them again ordered by the Zone the respective item is in.

You could also clone the array to a table, add the zone information, sort the table by zone and clone it again to the token label.

If you were to use the racks' addressing scheme rather than a label you could also control the pick order within an aisle/rack by also ordering the missions by the bayID.
