REFUELING VEHICLE ROUTING SYSTEM

The refueling vehicle routing system can use a refueling vehicle routing application to compute a set of fuel delivery routes for a fleet of refueling vehicles for multiple different target vehicles to be serviced via cooperating with a refueling scenario simulator. The refueling scenario simulator can run scenarios of different sets of refueling routes to refuel target vehicles in light of an available set of assets, and then the application can supply results of how the versions of the set of refueling routes for the fleet of refueling vehicles are going to satisfy anticipated refueling needs for the target vehicles; to indicate any refueling stops that could be late, early, and/or missed entirely, for a service window of time; as well as to show a measure of how cost effective each of the refueling routes are at the satisfying of the needs for the target vehicles.

11526480 · 2022-12-13 · ·

A mobile apparatus receives a route response including information identifying a starting location and a target location of a route and an encoding data structure encoding the route. The encoding data structure is a probabilistic data structure configured to not provide false negatives. The mobile apparatus uses the information identifying the starting and target locations to identify a decoded origin traversable map element (TME) and a decoded target TME of the mobile version of the digital map for the route; accesses map information for determining a cost value for TMEs of the digital map, wherein a TME that satisfies the encoding data structure is assigned a minimal cost value; determines a decoded route from the decoded starting TME to the decoded target TME based on the cost value assigned to the TMEs using a cost minimization route determination algorithm; and performs at least one navigation function using the decoded route.
