Abstract: A system for rapidly generating minimum length pilot training schedules which uses a branch and bound, and a mixed integer programming model with constraints to produce student and resource schedules at a device period level for all pilots of an airline.

Abstract: A traffic signal system has a main housing unit that encloses three nested arrow signals pointed towards the top, namely, a red arrow signal, a yellow arrow signal nested within the red arrow signal, and a green arrow signal nested within the yellow arrow signal. Each arrow signal is made with a plurality of LEDs. A smaller satellite housing unit, preferably one-third to two-thirds the height, is attachable to the main housing unit to provide a left or right turn signal also comprised of three nested arrow signals. Arrow signals are preferably removably installed. A removable cover provides access to the back of the three arrow signals. Both housing units are preferably waterproof and have hinged closures. An electrical terminal block provides for electrical connections. Removable visors shade the light from the LEDs. Water drain knockouts to the visor and housing units facilitate water removal.

Abstract: An automated optimization system for generating multiple alternative training and transition plans for airline pilots which include a recall of furloughed pilots, and limits to deviation of pilot start bid periods for training assignments from a specific bid period, wherein such plans are cost optimized to track payroll costs of pilots recalled from furlough, and the combined time for solving an MIP Model representation and generating such plans therefrom is less than one hour.

Abstract: An automated optimization system for generating training plans for airline pilots covering both pilot transitions and assignment to training classes for pilots who have received a system bid award, wherein such training plans are generated in less than one hour by first solving a MIP Model of the training/transition problem with an LP relaxation to determine a first level of feasibility, and then solving the MIP Model for an optimized feasible solution from which the training plan is derived.

Abstract: A nonwoven textile substrate formed from microfibers with a polyurethane matrix fully and/or partially impregnated therein, a nonazo disperse dye within microfibers, including the surface, and the matrix. The dyed fibers having an L value of about 35 or less, an ?E light fastness of about 6 or less when subjected to about 225 kilo-joules, and a long term crock of at least about 1.5.
