Hi Gordon
 

We have integrated with Descartes - Fleetwise and Omnitracs (formerly Roadnet).  Both of these systems are set-up to handle multi-truck routing and have some fairly advanced rules that can be put in place for route optimization. Our initial integrations were via a simple csv file that was loaded daily.  With Roadnet, we rewrote it leverage their Web Services.  That allows the orders to be fed in through-out the day so that dispatcher can handle same day deliveries.

We also have a scheduling application that we developed.  It allows a dispatcher to place orders on a truck/route.  After all of the order have been placed, we use Microsoft's Map routing to optimize the route for the truck.  It doesn't handle multi-truck routing, but it's very effective for smaller operations. There are some licensing considerations, so we don't purchase it directly from Microsoft, but instead go through a third-party.
