20090157438 | Quantifying Revenue and Profit Impact of Retiming Flights While Taking Into Consideration Non-Linear Ramifications and Constraints - A method, system and computer program product for efficiently quantifying the economic impact of retiming flights without the necessity of implementing the traditional airline forecasting system from scratch. A forecast module computes the difference in impact prior to and after the retiming of a flight. A flight grouping module, using the computed difference in impact, generates a new schedule, which is used by the forecast module to generate new changes in impact, until the schedule converges. A flyable module generates a list of retimed flights based on the converged schedule for resolving operational infeasibilities of the latter. The forecast module generates a profit for each of the retimed flights, which is used by a scheduling module to improve the schedule, which is used by the forecast module to revise the economic impacts for the list of all retimed flights. This process continues until no further economic improvement can be made. | 06-18-2009 |
20090125357 | Scheduling Procedure To Smooth The Flow of Air Traffic and Extend The Minimum Connect Time To a Greater Number of Passengers - A method for scheduling airplanes. Eastbound and westbound flights are scheduled to arrive to and depart from an airport within a small period of time (e.g., 5 minutes). By now scheduling both eastbound and westbound flights to arrive to and depart from an airport within a small block of time, the flow of air traffic is smoothed. Further, the scheduling structure of the present invention allows the passenger's connect time profile to be the same for all the passengers thereby extending the minimum connect time to a greater number of passengers. Further, the scheduling structure of the present invention allows staggered gating (gates are paired in such as a manner as to function as a single gate) thereby expanding gate separation as well as allowing a reduction or an elimination of the gap in times in the services being performed above and below the wings of an aircraft. | 05-14-2009 |
20090033496 | SYSTEM TO EFFECTUATE POINT OF USE CONTROL AND ACCOUNTABILITY OF MONITORED ARTICLES - The method and system for a material cabinet for use in cooperation with a plurality of articles stored in the material cabinet is disclosed. Each of the plurality of articles having a radio frequency identification tag attached thereto is connected through at least an antenna or a plurality of antennas installed in the material cabinet to a radio frequency identification reader, which is interpreted through a software in a computer system. This method and system has capability to effectuate point of use control of the stored articles through a database in the computer system. This method and system also implements a security mechanism through a lock system to secure the store articles from unauthorized user/stock clerks. | 02-05-2009 |
