Abstract
Example methods and systems for decomposing fleet planning optimizations via spatial partitions are described. An example method includes receiving information indicating a sequence of coverage requirements for a region over a period of time. The region is characterized by a plurality of landmarks and the period of time is divided into a plurality of phases. An individual coverage requirement indicates a desired number of vehicles of a plurality of vehicles for respective landmarks at a given phase. The method also includes dividing the region into a plurality of sub-regions, and determining sub-region fleet plans for the plurality of sub-regions based on estimates of one or more vehicles entering respective sub-regions and estimates of one or more vehicles leaving respective sub-regions. The method also includes combining the sub-region fleet plans to produce a fleet plan responsive to the sequence of coverage requirements for the region.
