Publication number: 20200364640Abstract: 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.Type: ApplicationFiled: May 15, 2020Publication date: November 19, 2020Inventors: Ying Zhang, Richard Lewis, Suresh Rangan, Mingzhou Jin
