An aspect includes receiving data for each of a plurality of unmanned aerial vehicles (UAVs) that includes a current location and final destination of each UAV. An aspect also includes calculating permutations of travel routes for each of the UAVs, which permutations are calculated as a function of the current locations of the UAVs and final destinations of each UAV. An aspect also includes applying a selected variable to the calculated permutations to produce proposed travel routes for the UAVs. An aspect further includes generating a routing plan from the proposed travel routes.
