Work Item travels on a pallet
I am trying to simulate an assembly line with 6 pallets fixed to the line where they transfers a single product around the whole assembly line. The product is placed on the pallet at station 1 and removed at station 7 by an operator. The pallet returns back to station one after the product is removed. How do I simulate the pallets and how do I fix it so the product can only go through the line if a pallet is a available.
