This project was designed for a small pharmaceuticals warehouse, which processes individual orders. Since this is pharmaceuticals industry, order pickers work with short lists of goods. This is why the flow lines have sizes convenient for transporting small boxes. A picker puts a box on the flow line, pushes and moves it across the racks, while putting the needed pharmaceuticals in the box. When the order is complete, the box goes down the flow line and gets to the control and packing zone.
