Takes a warehouse as a table and returns a placement
Takes a warehouse as a table and returns a placement. You supply the storage locations with their walking distance to the pick-and-drop point and, where they exist, their weight and volume limits; you supply the SKUs with pick frequency, weight and volume; and you may supply the joint-pick pairs.
