Methods and systems for determining a cyclical fleet plan satisfying a recurring set of coverage requirements
First Claim
1. A method comprising:
- receiving a sequence of coverage requirements for a region and an associated period of time, wherein the region is characterized by a plurality of landmarks and the period of time is divided into a plurality of phases, and wherein individual coverage requirements of the sequence of coverage requirements are indicative of a desired number of vehicles of a fleet of vehicles for one or more of the plurality of landmarks at an end of a given phase of the plurality of phases;
determining, by a processor, for each of one or more phases of the plurality of phases, possible routes that a vehicle of the fleet of vehicles located at one or more respective landmarks of the plurality of landmarks at a beginning of the phase could follow to reach one or more additional landmarks of the plurality of landmarks by an end of the phase; and
based on the sequence of coverage requirements and the determined possible routes, determining, by the processor, a cyclical pattern of trajectories for vehicles of the fleet of vehicles that minimizes a difference between a distribution of vehicles in the fleet of vehicles at a beginning of the period of time and a distribution of vehicles in the fleet of vehicles at an end of the period of time.

Abstract
Methods and systems for determining a cyclical pattern of trajectories for a fleet of vehicles are provided. In one example, a method comprises receiving a sequence of coverage requirements for a region and an associated period of time. For each of one or more phases of the period of time, possible routes that a vehicle located at one or more respective landmarks at a beginning of the phase could follow to reach one or more additional landmarks by an end of the phase are determined. Further, a cyclical pattern of trajectories for vehicles of a fleet of vehicles that minimizes a difference between a distribution of the fleet at a beginning of the period of time and a distribution of the fleet at an end of the period of time is determined.

12. A non-transitory computer-readable storage medium having stored therein instructions, that when executed by a computing device, cause the computing device to perform functions comprising:
-
receiving a sequence of coverage requirements for a region and an associated period of time, wherein the region is characterized by a plurality of landmarks and the period of time is divided into a plurality of phases, and wherein individual coverage requirements of the sequence of coverage requirements are indicative of a desired number of vehicles of a fleet of vehicles for one or more of the plurality of landmarks at an end of a given phase of the plurality of phases; determining for each of one or more phases of the plurality of phases possible routes that a vehicle of the fleet of vehicles located at one or more respective landmarks of the plurality of landmarks at a beginning of the phase could follow to reach one or more additional landmarks of the plurality of landmarks by an end of the phase; and based on the sequence of coverage requirements and the determined possible routes, determining a cyclical pattern of trajectories for vehicles of the fleet of vehicles that minimizes a difference between a distribution of vehicles in the fleet of vehicles at a beginning of the period of time and a distribution of vehicles in the fleet of vehicles at an end of the period of time. - View Dependent Claims (13, 14)

16. A system, comprising:
-
at least one processor; data storage comprising program instructions executable by the at least one processor to cause the system to perform functions comprising; receiving a sequence of coverage requirements for a region and an associated period of time, wherein the region is characterized by a plurality of landmarks and the period of time is divided into a plurality of phases, and wherein individual coverage requirements of the sequence of coverage requirements are indicative of a desired number of vehicles of a fleet of vehicles for one or more of the plurality of landmarks at an end of a given phase of the plurality of phases; determining for each of one or more phases of the plurality of phases possible routes that a vehicle of the fleet of vehicles located at one or more respective landmarks of the plurality of landmarks at a beginning of the phase could follow to reach one or more additional landmark of the plurality of landmarks by an end of the phase; and based on the sequence of coverage requirements and the determined possible routes, determining a cyclical pattern of trajectories for vehicles of the fleet of vehicles that minimizes a difference between a distribution of vehicles in the fleet of vehicles at a beginning of the period of time and a distribution of vehicles in the fleet of vehicles at an end of the period of time. - View Dependent Claims (17, 18, 19, 20)
