  • Schedule optimization using market modeling
    Patent number: 8504402
    Abstract: A schedule for a network of transportation resources is produced by iteratively generating sets of variables for each market pair using an objective function and based on at least an identified range of permissible departure or arrival times for each market pair and spacing parameters. Each variable represents a different set of possible departure or arrival times for a particular market pair. The proposed schedule is built based on the generated sets of variables for each market pair and a set of constraints.
