A major application is scheduling airline routes. The following examples help explain why solving transportation problems are important to airlines. Continental Airlines bases its route and schedule decisions on daily ticket data. Continental uses a computer program developed by American Airlines' Sabre unit. She noted schedulers take into consideration passenger demand, constraints of airports, the maintenance needs of the aircraft, the cost of flying individual aircraft, crew resources, and other factors.
Management can make better and more effective judgment by use of mathematical programming.
However, it is no substitute for the decision maker's ultimate judgment. 20, August 1941, pp. Kwak, N. K. Mathematical Programming with Business Applications.
