For instance, unit loads of SKUs are broken down into isolated items which are spread all over the warehouse. Or automated guided vehicles (AGVs) are applied to accompany human order pickers. This talk describes some novel warehousing structures specifically dedicated for e-commerce, introduces the resulting picker routing problems and presents some novel solution algorithms.
