Your IT Department
You need data – customer codes, addresses, delivery time windows and orders. This data already exists in your order processing system. If you are doing daily planning you need to be able to get that data out of there and into your Vehicle Routing system. Not only that, if you work with a Warehouse Management System (WMS) then quite likely you need to send the routes you produce back into the WMS for picking.
