  • Patent number: 11529095
    Abstract: There is provided a research framework system. For example, in some implementations there is provided a sleep prediction system for pilots including a first data structure storing collected research data related to pilot sleep patterns, a second data structure storing data related to a flight schedule associated with a pilot, and a sleep prediction module configured to access the data stored in the first and second data structures and calculate, by one or more processors using the data stored in the first data structure, a likelihood that the pilot associated with the flight schedule stored in the second data structure is sleeping at a given time.

  • Publication number: 20200364640
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for operations of obtaining input data that includes forecasting data and reserve duty pattern parameters. The operations include iteratively generating additional coverage rate columns for a reserve-demand coverage rate (RDCR) matrix until a stop criterion is satisfied, where each iteration includes: determining a shadow value indicating a marginal value of an incremental change in reserve-demand coverage of the airline trips by solving a set cover problem based on the set of coverage rate columns within the RDCR matrix and using linear problem constraints, the set of coverage rate columns selected for the iteration; generating a new reserve duty pattern, the new reserve duty pattern including an improvement value; and determining whether the improvement value of the new reserve duty pattern satisfies the stop criterion.
