Customers are demanding speed and accuracy, and warehouses are undergoing transformation from a solid physical facility used to house “mistakes” in forecasting called inventory to one that distributes products in the shortest possible time at the lowest possible cost. Growing number of partners and delivery points, shrinking volume but rising frequency of orders, ever shorter delivery time and stricter working hours of drivers, and ever increasing pressure to reduce inventories all con-tribute to growing pressures on supply chains. A trend toward smaller and fewer warehouses may well translate into more crossdocking operations in the 21st century [3].
